Emollients are essential ingredients in all types of skin care products. The selection of the emollient phase will determine skin feel, moisturization capacity, and stability of the formulation. Emollients can be classified according to their chemical composition or by their physicochemical properties. The basic building blocks of most emollients a...

Efficient synthesis of unsaturated FA esters of ascorbic acid is possible with only a small excess of one of the reactants in t-amyl alcohol using Candida antarctica lipase as biocatalyst. Using free acids, we obtained yields that were comparable to yields reached using vinyl-activated acyl donors (71, 80, and 86% yields of esters with FA excesses...

Polar lipids have an important role as emulsifiers and stability controlling agents in the food industry. The principal effects of the emulsifiers have been found to depend on the situation in which they are applied. They may act as stabilising additives, creating repulsive interactions between droplets. They may act as emulsifying agents, or they...

A rational method for the initial selection of candidate solvents in liquid chromatographic optimisation, i.e., targeting the search area in the multidimensional solvent mixture space, has been developed. This method utilises solvent system composition (vol. %) collected from the scientific literature or from scouting runs to perform the targeting,...

The phase behavior and the structure of ionic microemulsions, stabilized by sodium oleate and different alcohol cosurfactants, containing fatty acid esters or triglycerides as lipophilic components, have been investigated. Microemulsions containing triglycerides display a smaller stability region than microemulsions containing hydrocarbons or fatty...

Nonionic microemulsions containing triglycerides and fatty acid esters as lipophilic components have been studied. The phase inversion temperature (PIT) of the systems was determined by a conductometric method. Partial phase diagrams were constructed in the phase inversion temperature range. Water solubilization capacity of the nonionic surfactant...
