An active or functional organic compound is solubilized in a phenylethyl ester, e.g. an aryl carboxylic ester of 2-phenylethyl alcohol, as a solvent, cosolvent or additive, to form a composition thereof. Representative active or functional organic compounds include personal care products, e.g. sunscreens containing UVA/UVB absorbing compounds, such as avobenzone and benzophenone-3. Such compositions also show increased critical wavelength and UVA/UVB absorbance ratio performance properties.

Compositions containing phenethyl aryl esters as solubilizing agents for active organic compounds

A composition for retaining active ingredients in personal care compositions is described based on one or more polymers having a network structure in an oil phase in amounts from 0.01 to 10% by weight based on the total weight of the composition in the oil phase, the polymers including at least one associative agent, the composition further including at least one active component. The oil phase viscosity of each composition is at least 10 poise under a shear stress up to 1000 dynes/cm.

Composition and process for retaining active ingredients

A product-structuring composition which forms a bilayer lamellar gel network in an oil-in-water system comprising (a) a cationic swellant which is a fatty acid adduct of amidopropyldimethyl-2-hydroxyethyl ammonium halide, and (b) a gellant blend of low HLB emulsifiers having a resultant HLB of about 1.5 to 4.5.

Product-structurant composition for personal care formulations

A sunscreen concentrate in the form of a stable, uniform dispersion comprising, by weight:

Sunscreen concentrate

An emulsifier composition for skin care formulations, which is present in the form of a bilayer lamellar gel network, which is stable up to a temperature of about 50.degree. C., comprising by weight, about 3-40% of a high HLB swellant which is lecithin, and a blend of low HLB emulsifier gellants, to 100%, the blend of gellants having a resultant HLB of about 1.5 to about 5. In a skin care formulation, the lamellar gel network forms a discrete third phase between the oil and water phases.
