Aqueous solutions of surfactants exhibit remarkable differences in their adsorption properties on metal surfaces. This study evaluates the adsorption of surfactant mixtures on zinc metal surfaces. The adsorption of single surfactants cocamidopropyl betaine (CAPB) and sodium dodecyl benzenesulfonate (SDBS) and their mixtures from aqueous solution at...

Nanoemulsions are colloidal systems characterized by tiny droplet sizes with increased kinetic stability. Due to their exceptional properties, nanoemulsions find applications in cosmetics, drug delivery, and food industry. Nanoemulsions can encapsulate bioactive compounds and distribute them efficiently for specific purposes. In the current work, w...

This study examines the structural compatibility of various combinations of structurally diverse biosurfactants, saponin, a biosurfactant (derived from plants), and rhamnolipid and surfactin, biosurfactants derived from microorganisms) in the formulation of stable oil-in-water (O/W) nanoemulsion using the high-energy ultrasonication technique, and...

Plant diseases need to be controlled as they hamper the ecosystem by affecting the quality and availability of food, feed, crops, and fiber produced by plants and farmers worldwide. Different methods and approaches are unraveled to prevent and control plant diseases. In agricultural practice, fungal diseases are the most common crop-devastating dis...

Bacillus lipopeptides are promising biosurfactants that find applications in various sectors like biotechnological, cosmetics and biopharma due to their outstanding functionality like high specificity, low toxicity, and high surface activity. Among the different Bacillus species, Bacillus subtilis is well known for producing a biosurfactant surfact...

The ample interesting properties of lipopeptide biosurfactants- to name a few- hemolytic, antiviral, antifungal, and antibacterial properties are of significant interest to the research community. Surfactin, one of the most potent microbial surfactants, is a biosurfactant of the lipopeptide type with interesting physicochemical characteristics and...

The current work aims to formulate a stable cosmetic nanoemulsion using nature-derived ingredients such as surfactin (a lipopeptide-type biosurfactant produced by Bacillus sp) as an emulsifier, plant-based essential oil as a bioactive ingredient, and coconut oil as the base oil using high-energy ultrasonication method. To accomplish a stable nanoem...

Nanoemulsions are being increasingly utilized in the pharmaceutical, cosmetics, and food industries. They have gained special attention in the cosmetic sector owing to their smaller size and higher kinetic stability and their ability to improve the cutaneous penetration of active ingredients. In addition, they reduce transepidermal water loss, whic...

The present study is an attempt to throw insight into the significance of the type of nitrogen sources and their uptake pattern on the kinetics of surfactin production by Bacillus subtilis MTCC 2415. Batch kinetics studies revealed that surfactin production was strongly influenced by nitrate ions than ammonium ions. A maximum surfactin concentratio...

Consumers of face-care cosmetics have been continuously evolving and are more receptive to skin-care products that integrate both health and wellness. This subsequently prompted cosmetic manufacturers to renew their formulation approaches by allowing gradual replacement of synthetic ingredients with promising natural alternatives. Among various ava...
