Abstract

Substantially anhydrous compositions including at least 10% by weight of a C 2 or C 3 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 13.9. The composition has a volume fraction of oil portion relative to the sum of the oil portion plus C 2 or C 3 mono alcohol that is greater than 0.091.

Claims (19)

1 . A composition comprising:

at least 10% by weight of a C 2 or C 3 mono-alcohol;

a solid organic UV-filter dissolved therein;

a film-forming polymer consisting of an oil-insoluble film-forming polymer;

an oil portion comprising one or more oils, wherein the oil portion is miscible with the C 2 or C 3 mono-alcohol, wherein the oil portion has an interfacial tension with water of greater than 9 mN/m and less than 13.9 mN/m, and wherein the composition has a volume fraction of the oil portion relative to the oil portion plus the C 2 or C 3 mono-alcohol that is about 0.091 or greater, and wherein the composition is substantially anhydrous.

2 . The composition of claim 1 , wherein the composition comprises 10% to about 90% of the C 2 or C 3 mono-alcohol.

3 . The composition of claim 1 , wherein the composition comprises 15% to about 57% of the C 2 or C 3 mono-alcohol.

4 . The composition of claim 1 , wherein the composition comprises 20% to about 57% of the C 2 or C 3 mono-alcohol.

5 . The composition of claim 1 , wherein the oil portion has an interfacial tension with water of from about 10 mN/m to about 13 mN/m.

6 . The composition of claim 1 , wherein the oil portion includes diisopropyl adipate.

7 . The composition of claim 1 , wherein the oil portion has an interfacial tension with water of from about 10.5 mN/m to about 12.5 mN/m.

8 . The composition of claim 1 , wherein the oil portion has an interfacial tension with water of from about 11.0 mN/m to about 12.0 mN/m.

9 . The composition of claim 1 , wherein the volume fraction of the oil portion relative to the oil portion plus the C 2 or C 3 mono-alcohol is greater than 0.20.

10 . The composition of claim 1 , wherein the volume fraction of the oil portion relative to the oil plus the C 2 or C 3 mono-alcohol is from about 0.33 to about 0.80.

11 . (canceled)

12 . The composition of claim 1 , wherein the solid organic UV-filter is selected from the group consisting of avobenzone and oxybenzone.

13 . The composition of claim 1 , wherein the composition comprises from about 0.5% to about 20% of the solid, organic UV-filter dissolved therein.

14 . The composition of claim 1 , wherein the composition comprises from about 0.5% to about 9% of the solid, organic UV-filter dissolved therein.

15 . The composition of claim 1 , wherein the oil portion comprises a liquid, organic UV-filter.
