Abstract
Substantially anhydrous compositions including at least 10% by weight of a C2 or C3 mono-alcohol, a solid, organic UV-filter dissolved therein; and an oil portion including one or more oils, the oil portion having an interfacial tension with water of greater than 9 and less than 45, where the composition has a volume fraction of oil relative to oil plus C2 or C3 mono-alcohol that is about 0.47 or greater, and is substantially free of a mixture of a low-volatility, C2-C8 liquid silicone and a branched fatty acid ester of a polyprotic carboxylic acid in a ratio of from about 3:1 to 4.25:1

A composition comprising:
- at least 10% by weight of a C2 or C3 mono-alcohol;
- a solid organic UV-filter dissolved therein;
- an oil portion comprising one or more oils, wherein the oil portion is miscible with the C2 or C3 mono-alcohol, wherein the oil portion has an interfacial tension with water of greater than 9 and less than 45, and
- wherein the composition has a volume fraction of the oil portion relative to the oil portion plus the C2 or C3 mono-alcohol that is about 0.47 or greater, and wherein the composition is substantially free of a mixture of a low-volatility, C2-C8 liquid silicone and a branched fatty acid ester of a polyprotic carboxylic acid in a ratio of from about 3:1 to 4.25:1, and wherein the composition is substantially anhydrous.
