INTRODUCTION
The shampoo sector is probably the largest unit sale amongst the
hair care products since shampoos are one of cosmetic products used
in daily life. Shampoos are primarily been products aimed at
cleansing the hair and scalp. Zizipus spina-christi is a tree
indigenous to the north districts of United Arab Emirates. The leaves
of this plant, which are locally known as Sedr and Konar, have
been traditionally used for washing the hair and body. Application of
the powdered leaves is said to darken and lengthen womens hair1.
Zizipus Spina-christi leaves are also used in the folk medicine as an
antiseptic, antifungal and anti-inflammatory agent, and for healing
skin diseases such as atopic dermatitis2. The plant is already used in
many parts of the world for the care of the skin3. The chemical
composition and phytochemicals present in the plant would suggest
and substantiate the ethnobotanical and cultural reliance on this
plant. From the constituents, it contains four saponin glycosides4.
Saponin is one of the natural washing agents that help to absorb
excess sebum without causing adverse reactions. In addition to the
emollient effect of saponins their antibacterial and antifungal
properties are important in cosmetic applications. Selected
ingredients of shampoo have been popular with the consumer are
currently under attack because of potential risks.
Zizyphus spina-christi has shown to have antimicrobial activity
against bacteria, fungi and other pathogens that are normally quite
resistant5. Therefore the ideology of preparation of a self preserved
with low concentration of a detergent will be advantageous and
reduce the risk of chemicals.
Sodium lauryl sulfate based detergents are the most common but the
concentration will vary considerably from brand to brand and even
within a manufacturer's product range. Cheap shampoos may
contain a high detergent concentration while expensive shampoos
may contain very little of a cheap detergent5.
Our endeavor was to formulate a herbal shampoo from Ziziphus
spina leaves. The prepared formulas were in vitro evaluated for
detergency, foam volume and stability, surface tension, wetting
properties, pH, viscosity, conditioning effects and stability in
comparison to commercial brand (Cedr shampoo®, Sehat Company,
Iran). The test methods had been selected based upon their
simplicity, rapidity and reproducibility. Furthermore, in vivo eye
irritation and skin sensitization tests were performed using the
candidate formula.
MATERIALS AND METHODS
Plant collection
Leaves of Ziziphus spina were obtained from Haj Seed gardens (Al-
Muhaisanah 1, Dubai, UAE) in September 2011. Authentication of
the samples was done by the Head of Department of Pharmacognosy
at Dubai Pharmacy College.
Preparation of plant extract
The collected leaves were cleaned from unwanted foreign materials
and accurately weighed. Then samples were homogenized and
extracted using ethanol (70 % v/v). The extracts were filtered and
concentrated to dryness under reduced pressure and controlled
temperature (50-55°C) to obtain solvent-free semisolid extracts. The
solvent-free semisolid extract obtained was washed, weighed and
packed into plastic containers and stored at room temperature in the
laboratory until used for the antimicrobial studies. The percentage of
yield was 16.34%.
Preparation of herbal shampoos
To formulate a clear shampoo base, four samples, designated as F-0,
F-1, F-2 and F-3 were prepared as shown in Table 1. F1, F2 and F3
were prepared by incorporation of 5, 10 and 20 % w/w of Z. spina
extract in 10%, 5% and 0% w/w of sodium laureth sulfate
respectively. The volume was completed with distilled water to
100mL. F-0 was control sample (without plant extract).
Evaluation of herbal shampoos
To evaluate the prepared formulations, quality control tests
including organoleptic and physicochemical characterization such as
pH, solid contents and viscosity were performed. As well to ensure
the quality of the products, specific tests for shampoo formulations
including: surface tension, foam volume and foam stability,
detergency, eye irritation, skin sensitization tests and preliminary
stability study were also carried out. The results were compared with
frequently used marketed herbal shampoo (Cedr shampoo®, Sehat
Company, Iran) that was considered as reference

Physical appearance/visual inspection
All samples were observed for their physical appearance/visual
inspection. The prepared formulations were evaluated in terms of
their clarity, foam producing ability and fluidity6.
Determination of pH
The pH of shampoo solution (10% w/v) in distilled water was
determined at room temperature7. The pH was measured by pH
meter (Mettler Toledo, USA).
Percentage of solid contents
Four grams of the prepared shampoo were placed in a clean dry
evaporating dish. The weight of the dish and shampoo was
determined. The liquid portion of the shampoo was evaporated by
placing on a hot plate. Then the weight of the shampoo solid
contents after complete drying was determined.
Surface tension measurement
The surface tension measurement of the diluted shampoos (10% w/v
in distilled water) was carried out at 20 °C using du Nuoy
tensiometer. (Lauda, Germany)
Wetting time
The canvas was cut into 1-inch diameter discs having an average
weight of 0.44 g. The disc was floated on the surface of shampoo
solution 1% w/v and the stopwatch started. The time required for the
disc to begin to sink was measured accurately and noted as the
wetting time.
Rheological property
The viscosity of the prepared formulations was measured at room
temperature using a programmable rheometer (Brookfield DV-III
Ultra, Brookfield Engineering Laboratories Inc., USA) fitted with a
spindle type S 17 while set at different spindle speeds. The best
approach is to take multipoint measurements approximate to those of
the process being modeled8. All measurements were performed in
triplicate at room temperature and the viscosity profile of the
shampoos was measured.
Dirt dispersion
Two drops of shampoo were added in a large test tube contain 10 ml
of distilled water. One drop of India ink was added; the test tube was
Stoppard and shacked for ten times. The amount of ink in the foam
was estimated as None, Light, Moderate, or Heavy.
Foam, volume and stability
The foam volume test was determined by mixing the prepared
formulas with distilled water, hard water (Ca++ 150 ppm) and a
standard soil. The foam was produced by mixing in a kitchen
blender. An artificial sebum was used for detergency evaluation
(0.25 mL of sebum10% in hexane for 4g of the shampoo). Forty
milliliters of shampoo solution 10% w/v in distilled water was
blended for 5 sec in a kitchen blender. The height of the foam
generated was measured immediately and after 3 min, the test was
repeated in hard water, standard soil and in the presence of artificial
sebum.
On the other hand, Ross-Miles foam column method was used to
evaluate the foaming stability of the prepared formulations. Briefly,
0.25% and 0.5% of aqueous solutions of each formulation were
prepared and placed in burette of 100 mL capacity at the room
temperature. They were then individually poured from a height of 50
cm into a measuring cylinder and the height of produced foam was
measured. The foam height after 10 and 20 minutes were also
determined9, 10.
Detergency evaluation
Thompson method11 was used to evaluate the detergency of the
prepared shampoos with minor modification since our results were
evaluated gravimetrically. Hair tresses of Asian (Indian) origin were
obtained from the market. The tresses were prewashed with 5% SLS
solution, dried and cut into 10 inch, 3 g swatches. The sebum
composition was chosen to include a variety of functional groups
similar to that in actual sebum.
The actual formula for the artificial sebum used in our study was
olive oil 2%, coconut oil 15%, stearic acid 15%, oleic acid 15%,
paraffin wax 15% and cholesterol 20%. The hair swatch (3 g) was
suspended in 20 ml of a 10% sebum solution in hexane for 15 min
with intermittent shaking. The swatch was removed, the solvent
evaporated at room temperature and the hair swatch weighed to
determine the sebum load. Fifteen swatches were treated similarly
and the soil levels were found to range from 9.96 to 11.05%, each
swatch was then split into two equal samples of 1.5 g each: one for
the shampoo treatment and the other to act as internal control to
overcome the tress-to-tress variation in soil levels. The control
swatch was left untreated. The test swatch was washed with 0.1 ml
of a shampoo solution 10% using the finger method described by
Thompson et al. It was then dried using a hair dryer and further
dried in an oven at 60 degrees for 4 hours to ensure uniform
moisture content.
The sebum remaining in the test swatch after shampooing and that in
the unwashed control swatch was then extracted, using 20 ml hexane
in a stoppered flask for 30 minutes on a rotary shaker. The hexane
solution was then evaporated to dryness and the sebum extracted
from the test and control swatches were weighed. Detergency was
evaluated as a percentage of sebum removed after shampooing
according to the following equation:
Detergency = 100 (T x 100/C)
Where T is the weight of sebum in test swatch and C is the weight of
sebum in control swatch.
Eye irritation test
Animals (albino rats) were collected from animal house of Dubai
Pharmacy College. Ethical approval to conduct this experiment was
obtained from the Research Committee of the College. Shampoo
solution 1% was dripped into the eyes of six albino rabbits with their
eyes held open with clips at the lids .The progressive damage to the
rabbits eyes was recorded at specific intervals over an average
period of five minutes. Reactions to the irritants can include swelling
of the eyelid, inflammation of the iris ,ulceration, hemorrhaging
(bleeding) and blindness12.
Skin sensitization test
Animals (guinea pigs) were divided into six groups (n=3). On the
previous day of the experiment, the hairs on the backside area of
guinea pigs were removed. The animals of Group I was served as
negative control (without any treatment). Animals Group II, III and
IV were applied with shampoo formulation F1, F2, F3, respectively.
While animals group V was considered as a reference (applied with
the commercial product). Shampoos were applied onto nude skin of
animals groups. A 0.8% v/v of formalin aqueous solution was
applied as a standard irritant on animals Group VI (positive control)
up to 72 hours. The application sites were graded according to a
visual scoring scale, always by the same investigator. The erythema
scale was as follows: 0: none, 1: slight, 2,:well defined, 3: moderate
and 4: scar formation severe13.
Preliminary stability study
Stability and acceptability of organoleptic properties (odor and
color) of formulations during storage indicate chemical and physical
stability of the prepared shampoos formulations. This study was
conducted on a candidate formula (F2). Samples were placed in dark
glass tubes and stored in a chamber at 45°C and 75% relative
humidity. Their appearance and physical stability was inspected for
a period of 3 months at interval of one month13, 14. To assess their
mechanical stability, each sample was centrifuged at 2400 rpm for 3
minutes and then its structural stability was inspected15.
Statistical analysis
The results were given as mean± S.D. (n=5). One-way analysis of
variance (ANOVA) comparison test was used to compare
characteristics of different formulations with the commercial
product. A p value of 0.05 was considered to be significant.

RESULTS AND DISCUSSION
Evaluation of herbal shampoos
Physical appearance
The results of visual inspection of shampoo formulations are showed
in Table 2. It can be noticed that, all formulations had good
characteristics with respect to appearance and foaming.
pH
The pH of shampoo formulations has been shown to be important
for improving and enhancing the qualities of hair, minimizing
irritation to the eyes and stabilizing the ecological balance of the
scalp8.
The pH of shampoo solution 10% in distilled water was determined
at 25 C and the results are presented in Table 3.
The current trend to promote shampoos of lower pH is one of the
ways to minimize damage to the hair. Mild acidity prevents swelling
and promotes tightening of the scales, thereby inducing sheen. As
seen from Table 3, only shampoo F3 shows a higher pH nearly the
same as the commercial one, whereas all the other shampoos are
acid balanced and were ranged 5.5 to 5.8.
Solids contents
If the shampoo has too many solids it will be hard to work into the
hair or too hard to wash out. The solids contents of the prepared
formulas were in a range of 22-28%. Thus they can be considered
easy to wash out shampoos (Table 3). No significant difference (p<
0.05) among the prepared formulas and the commercial brand
(reference).
Surface tension
All shampoo formulations showed similar reduction in surface
tension (p< 0.05), as shown in Table 3. Surface tension reduction is
one of the mechanisms implicated in detergency. The reduction in
surface tension of water from 72.8 dynes cm-1 to 32-37 dynes cm-1
by the shampoos is an indication of their good detergent action.
Wetting action
The rate of wetting or the wetting ability of surface-active agents is
commonly used to determine their comparative efficacies. Although
the Draves test16 has been adopted as the official test, the canvas
disc wetting test17 offers a number of advantages over it. The canvas
disc method is more accurate and time saving than the official test.
Also, the unlike materials and apparatus required for the canvas test
are easily available in any laboratory, unlike the Draves test, which
requires cotton skeins, anchors and weights. Hence, we have used
the canvas disc method for our work.
Different types of canvas were tried for the test and one that gave an
effective balance between time saving and testing efficiency was
chosen for the test.
The wetting ability of a substance is a function of its concentration.
By comparing the results in Table 3 with those of detergency% in
the next column it seems fair to conclude that shampoo F3 contains
the maximum concentration of natural detergents, and hence shows
maximum detergency and minimum wetting time. By contrast,
shampoo F0 shows minimum detergency and maximum wetting
time; and shampoos F1, F2 and reference showed intermediate
detergency and wetting times.
Detergency evaluation
Although cleaning or soil/sebum removal is the primary aim of a
shampoo, experimental detergency evaluation has been difficult to
standardize, as there is no real agreement on a standard soil, a
reproducible soiling process or the amount of soil a shampoo should
ideally remove.
Earlier work on detergency evaluation was done using greasy wool
yarn by Barnette and Powers18. Later, the approach turned to
evaluating detergency using as little as 10 mg of hair clippings
obtained from salons19. Thompson et al.11 used hair tresses soiled
with artificial sebum for evaluating detergency.
However our formulas were evaluated gravimetrically and results
indicated a significant difference (p< 0.05) in the amount of sebum
removed by different shampoos. Shampoo F0, being a frequent-use
cleanser, was expected to have the minimum detergency. Shampoos
F2 and F3 also show moderate detergency and may be regarded as
mild cleansers. However, shampoos F1 and reference are 'active'
cleansers and are more suitable for oily hair than normal hair, (Table
3).
Cleaning action
Cleaning action was tested on wool yarn in grease. Although
cleaning or soil/sebum removal is the primary aim of a shampoo,
experimental detergency evaluation has been difficult to standardize,
as there is no real agreement on a standard soil, a reproducible
soiling process or the amount of soil a shampoo should ideally
remove. As seen from the results, there is a significant difference in
the amount of sebum removed by the different shampoos. The
results of detergency studies showed that the final formulation has
significantly similar detergency ability, when compared with the
marketed formulations and it was found in between 18-33%. Table
3.
Dirt dispersion
Shampoo that causes the ink to concentrate in the foam is considered
poor quality; the dirt should stay in water. Dirt that stays in the foam
will be difficult to rinse away. It will redeposit on the hair. All three
shampoos (F1, F2 and F3) showed similar results as the marketed
one, except the control (F0). These results indicate that no dirt would
stays in the foam; so prepared and marketed formulations are
satisfactory20, 21.
Viscosity
Product viscosity plays an important role in defining and controlling
many attributes such as shelf life stability and product aesthetics
such as clarity ease of flow on removal from packing and spreading
on application to hair and product consistency in the package. The
flow characteristics of non-Newtonian materials are usually not
measured with a single data point, because their viscosity is
dependent on the shear rate. The best approach is to take multipoint
measurements approximate to those of the process being modeled22.
Fig.1. indicates that shampoo F0 and F1 are low viscosity products,
whose viscosity remains almost unchanged over the range of r.p.m
used. Shampoo F2 and F3 show pseudo plastic behavior the same as
the commercial one (reference), which is a desirable attribute in a
shampoo formulation. At a low r.p.m., these shampoos show high
viscosity. On increasing the shear, the viscosity drops, which would
allow ease of spreading on the hair.
Foam volume and stability
All the investigated shampoos showed similar foaming
characteristics in distilled water as well as hard water. However, in
the presence of soil, only shampoos F2 and F3 foamed well as the
commercial one (Table 4). From a practical point of view, shampoos
F0 and F1 would not foam well during the first hair wash, due to the
presence of soil. However, during the second wash, i.e. once the
sebum has been removed; all five shampoos would show
comparable foaming properties. A point to be noted here is that there
does not seem to be any direct correlation between detergency and
foaming, which only confirms the fact that a shampoo that foams
well need not clean well.
Eye irritation test
There was slight irritation on application of preparation. The animal
recovered well within 3 days as the case with the reference. No eyes
irritation, dryness or scaling caused by the tested formulations.
Skin sensitization test
The all formulation showed no skin sensitization including marketed
shampoo except F1. The adverse reactions may occur to one of the
primary constituents of the cosmetic formulation or contamination
or procedural misconduct. Other additives are the second most
Rasool Bazigha Kadhim et al / IJRAP 2011, 2 (6) 1802-1806
International Journal of Research in Ayurveda & Pharmacy
common cause of skin reactions besides fragrances. In most cases,
these were only mild or transient such as stinging sensation. In few
cases, reactions may be more severe with redness, edema.
Preliminary stability study
Stability and acceptability of organoleptic properties (odor and
color) of the selected F2 during the storage period indicated
complete chemical and physical stability of the tested formula .The
stability of the herbal shampoo formulation is shown in Table 5.
CONCLUSION
The present study aimed to prepare a stable, self preserved a
shampoo formulation contains low detergents to reduce the risk of
chemicals. Results showed that no significant difference between
both F2 and F3 in comparison with the reference regarding their
physicochemical properties and their in vivo evaluation. However
these formulas contain no preservative and less detergent contents as
the reference that make them in favorite on the commercial product.

... The amount of Indian ink was visually estimated in the foam as none, light, moderate and heavy. Shampoos that caused the color to stay in the foam were considered low quality [16]. ...
... Dirt dispersion is an important quality attribute of shampoos and it is linked with the cleansing action of shampoos. Generally, shampoos that cause the ink to stay in the foam instead of the liquid portion are considered poor quality products because of difficulty in washing away the ink, consequently, the dirt would be difficult to remove from the hair [16]. Among the prepared tea tree oil shampoos, S2, S3, S5, and S6 had light ink in their foam section while no ink was detected in the S1 and S4 shampoo formulation ( Table 3). ...

Background Dandruff is a common scalp condition affecting half of the population of the world. Objective The current study aimed at developing anti-dandruff shampoos containing tea tree oil, which is believed to be effective against Malassezia furfur, a fungus involved in dandruff production. Methodology Various shampoos containing tea tree oil in 0.5 to 3% concentration were prepared after careful selection of various shampoo ingredients. The formulated shampoos were subjected to various quality tests such as pH, viscosity, foam production, dirt dispersion, wetting time, surface tension, solid contents, and antimicrobial activity against a model fungal strain, namely Candida albicans. The formulated shampoos were also compared with the marketed shampoos for quality attributes. Results The results revealed that tea tree oil shampoos had pH values in the range of 5 – 6, which is close to the slightly acidic skin’s pH and considered as good for hair. All other quality attributes were comparable to the marketed products. The marketed shampoos had superior antifungal activity due to the presence of zinc pyrithione or a higher concentration of salicylic acid or selenium sulfide. Notwithstanding, the tea tree oil shampoos demonstrated an appreciable antifungal activity due to synergistic effects of tea tree oil, sodium lauryl sulphate, and salicylic acid. Furthermore, the tea tree oil shampoos were stable during two months-long stability testing. Conclusion Thus, tea tree oil anti-dandruff shampoos have the potential to address the dandruff problem.
... Dirt dispersion activity was evaluated by the method of Saad and Kadhim (2011). 25 In this test two drops of 1% and 5% solution of test drug extracts were added in a large test tube containing 10 ml of distilled water. One drop of Indian ink was added; the test tubes had been stoppered and shook ten times. ...
... Dirt that stays in the foam will be difficult to rinse away, it will redeposit on the hair. 25 The dirt dispersion activity is due to a combined property of surface tension. It is inversely proportional to surface tension; lower the surface tension more is the dirt dispersion activity. ...

Aim of the study: To evaluate the detergent activity of aqueous extract of Ammi majus L. and Psoralea corylifolia L. Materials and methods: The detergent activity of aqueous extract of test drugs was evaluated by using a standard physicochemical test with Sodium lauryl sulfate (SLS) as a standard drug. Surface tension was measured by Du Nouytensiometer; Dirt dispersion by using Indian ink; Cleaning ability by greasy wool yarn test; Foaming properties by cylinder shake method and Wetting ability by canvas disc method. pH values and total saponin was also determined. Both the test and standard drugs were analyzed in 1% and 5% concentrations. Results: The aqueous extract of both the test drugs produced a significant detergent effect at both the concentration but less than SLS as it exhibited a pronounced effect in all the parameters except detergency. The test drugs were found to be acidly balanced; exhibited a prominent surface tension reduction, high foaming, wetting, and cleaning ability with a good quantity of saponin. Conclusions: Based on the above results it can be concluded that the aqueous extract of test drugs has significant surface-active properties thus these drugs can be used as a natural surfactant.
... Dirt dispersion is an important criterion for evaluating the cleaning action of shampoos. Shampoos that cause the ink to concentrate in the foam are considered to be of low quality because the ink or dirt remaining in the foam is difficult to rinse out and is re-deposited on the hair (Saad and Kadhim 2011). In the studies conducted by Kumar and Mali (2010), Khaloud and Shah (2014) and Bushra et al. (2018) observed that the shampoo samples analyzed showed good results as there was no ink distribution in their foam. ...

In light of recent developments in the scientific and technological world, herbs are widely used as remedial agents. This study was aimed to formulate and evaluate the safety and the efficacy of herbal antidandruff shampoo from Ziziphus spina-christi (Sidr) leaves extract, which is used traditionally for several medical and cosmetic purposes. Sidr leaves were extracted by maceration using ethanol as a solvent. The antifungal activity of the plant extract was tested against M. furfur. In-vivo study of the extract has been evaluated with daily oral doses (50, 100, and 200 mg/kg) for 28 days for tested rats, followed by, evaluation of the biochemical and histological parameters. Subsequently, the plant extract was formulated as a shampoo and tested for its antidandruff efficiency on 80 volunteers, with dandruff, for four consecutive weeks. An obvious antifungal activity against M. furfur has been displayed by sidr extract, where 86% of the tested volunteers substantially ameliorated from dandruff with sidr shampoo formulation. The toxicity of the extract was not shown aberrant results as compared with the control group in biochemical analysis. However, mild histological harmful effects on the liver and kidney tissues appeared at high doses of the extract, 100 and 200mg/kg, when used orally. As a conclusion, sidr extract could be used topically as anti-dandruff shampoo formulation with high efficiency and good safety

Industrial processes generate toxic organic molecules that pollute environment water. Phenol and its derivative are classified among the major pollutant compounds found in water. They are naturally found in some industrial wastewater effluents. The removal of phenol compounds is therefore essential because they are responsible for severe organ damage if they exist above certain limits. In this study, ground Ziziphus leaves were utilized as adsorbents for phenolic compounds from synthetic wastewater samples. Several experiments were performed to study the effect of several conditions on the capacity of the Ziziphus leaves adsorbent, namely: the initial phenol concentration, the adsorbent concentration, temperature, pH value, and the presence of foreign salts (NaCl and KCl). The experimental results indicated that the adsorption process reached equilibrium in about 4 hours. A drop in the amount of phenol removal, especially at higher initial concentration, was noticed upon increasing the temperature from 25 to 45oC. This reflects the exothermic nature of the adsorption process. This was also confirmed by the calculated negative enthalpy of adsorption (-64.8 kJ/mol). A pH of 6 was found to be the optimum value at which the highest phenol removal occurred with around 15 mg/g at 25oC for an initial concentration of 200 ppm. The presence of foreign salts has negatively affected the phenol adsorption process. The fitting of the experimental data, using different adsorption isotherms, indicated that the Harkins-Jura isotherm model was the best fit, evident by the high square of the correlation coefficient (R2) values greater than 0.96. The kinetic study revealed that the adsorption was represented by a pseudo-second-order reaction. The results of this study offer a basis to use Ziziphus leaves as promising adsorbents for efficient phenol removal from wastewater.

Saponins are natural surfactants that are readily biodegradable, generally non-toxic to humans and environmentally friendly. In this work, the surface properties, coffee ring effect and characterisation of the extract of Albizia procera pod were studied. It showed good washing power and good soil or dirt dispersion and cleaned effectively at low surface tension. The extract is equivalent to commercial detergents, making it a viable biosurfactant. In addition to the critical micelle concentration, there is a lower concentration at which the surface tension curves flatten out. We have named this concentration “Minor Critical Micelle Concentration”. The surfactant also reduces the coffee ring effect of a drying droplet and provides a reasonably uniform distribution of suspended particles. This effect can be used to estimate the critical micelle concentration. The Fourier transform infrared spectrum of the extract shows the presence of the functional groups –OH, C–H, C=C and C–O–C, which are also found in saponins.

A simple method to quantify hair damage during combing or brushing has been developed. The method involves collecting hair fragments that are chipped from hair during combing and quantitatively measuring the amount of protein using a colorimetric procedure capable of detecting as little as 5 Ixg of protein per mi. Using this procedure on hair tresses in the laboratory and on live heads (half-head tests), we were able to demonstrate significant differences in protein loss during post-shampoo combing of undamaged and chemically damaged hair previously treated with various shampoos/conditioners. The method is applicable to different types of hair tested, namely, Caucasian, Asian, Oriental and Negroid.

An analytical protocol is described for the assessment of relative shampoo detergency on hair by which raw materials, prototype formulations, and competitive products can be objectively contrasted. Hair tresses are soiled with a standard nine-component synthetic sebum mixture using 2% and 10% sebum in hexane solutions. Soil removal is determined under three test conditions: bulk bath washer, traditional "finger squeeze," and controlled-pressure apparatus. Gas chromatography of the residual sebum components serves as the analytical basis for the investigations. Comparisons are based upon the "tracking" of 20 gas chro- matograph peaks which are indicative of the various sebum fractions. An internal control sample is used to compensate for any sample-to-sample variation in soiling level. Solutions (10%) of different surfactant types, ammonium lauryl sulfate (ALS), sodium laureth 2-sulfate (AES) and sodium alpha olefin C14-C16 sulphonate (AOS), are evaluated with both single and multiple soiling and washing cycles to investigate sebum partitioning as a function of the active ingredient type. Sebum fraction removal is seen to be dependent upon: 1. Washing technique--The finger squeeze method of sample treatment is the least reproducible of the sample treatments investigated due to the high degree of operator interaction required. 2. Surfactant system--The type of surfactant determines which sebum fractions are removed and to what extent.
