Assignee:

ISP Investments Inc. - Wilmington DE

International Classification:

A61K 7/42

US Classification:

424 59, 424 60

Abstract:

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.

A61K007/42

US Classification:

424059000, 514532000, 514538000

Abstract:

An active or functional organic compound is solubilized in a diaryl organic compound having a polar or polarizable functional group therein, as a solvent, cosolvent or additive, to form a composition thereof. Representative active or functional organic compounds include those present in personal care products, e.g., sunscreens containing UVA/UVB absorbing compounds, such as avobenzone, benzophenone-3, and 4-methylbenzylidene camphor. Such compositions also show increased SPF, UVA/UVB absorbance ratio, and critical wavelength performance properties.
