Personal care compositions with improved solubility of a solid UV active

摘要

A personal care composition may have an isosorbide diester having the formula:;wherein R′ and R″ are independently selected from a straight or branched C1-30 chain, which may be saturated or unsaturated. The composition may further comprise a solid UV active soluble in the isosorbide diester and a dermatologically acceptable carrier. The personal care composition may be in the form of an emulsion having an aqueous phase comprising water and an oil phase. The oil phase may comprise the isosorbide diester and a solid UV active soluble in the isosorbide diester. In a particular embodiment, the solid UV soluble in the isosorbide diester UV active may be selected from 4-tert-butyl-4′-methoxy dibenzoylmethane, bis-ethylhexyloxyphenol methoxyphenyl triazine, and combinations thereof. Methods of making the aforementioned personal care compositions are disclosed.

1. A personal care composition comprising:
a. an isosorbide diester solvent having the formula:wherein R′ and R″ are independently selected from a straight or branched C1-30 chain, which may be saturated or unsaturated;
b. a solid UV active soluble in the isosorbide diester solvent, wherein the isosorbide diester solvent is present in an amount sufficient to solublize the solid UV active and the amount of isosorbide diester solvent is at least 2 parts, by weight, isosorbide diester solvent to every 1 part, by weight, solid UV active; and c. a dermatologically acceptable carrier.
