A photo protective topical composition, comprising: (i) at least one functional active; and (ii) at least one solubilizing compound having the structure of Formula I: wherein R is C-Ccycloalkyl or linear or branched alkylcycloalkyl, wherein the ring size is C-C; R, R, and Rare each independently selected from the group consisting of H, and linear or branched C-Calkyl, provided that at least two of R, R, Rare H; wherein the solubilizing compound is present in an amount effective to solubilize said functional active. Also disclosed is a method for treating skin, lips, nails, hair, ears, eyelashes, eyebrows and/or scalp with an effective amount of composition.

Solubilizing agents for active or functional organic compounds

A concentrate including, by weight (a) 10% to 60%, preferably 25% to 35%, of a saturated fatty acid selected from stearic or palmitic acid, or mixtures thereof, in an adduct of an amidopropyldimethyl-2-hydroxyethyl ammonium halide, with substantially no free acid present, and (b) 40% to 90%, preferably 65% to 75%, of a low molecular weight alcohol or saturated fatty alcohol or alcohols, for use in personal care products, including hair care and skin care compositions.

Personal care compositions

An active or functional organic compound is solubilized by an ester of an aryl alcohol, e.g., phenethyl, benzyl or substituted benzyl alcohol, and an alkyl or cycloalkyl carboxylic acid, or by a carbonate of said aryl alcohol and an alkyl or cycloalkyl carbonic acid.

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.
