Abstract

A topical composition comprising at least one α-cyanodiphenylacrylate and dimethicone silylate.

Claims

1. A topical composition comprising at least one α

-cyanodiphenylacrylate and dimethicone silylate present in an amount sufficient to increase blocking of UVA light when compared to the same composition not containing dimethicone silylate.

2. The composition of claim 1 further comprising an organosiloxane emulsifier.

3. The composition of claim 1 wherein the α

-cyanodiphenylacrylate has the general formula;

4. The composition of claim 3 wherein R₁ and R₂ are each independently C_1-8 alkoxy, and any non-alkoxy radical R₁ or R₂ is hydrogen;

and R₃ is a straight or branched chain C_2-20 alkyl.

5. The composition of claim 4 wherein R1 and R2 are each independently methoxy, and any non-methoxy R₁ or R₂ is hydrogen;

and R₃ is a C_2-20 alkyl.

6. The composition of claim 1 wherein the α

-cyanodiphenylacrylate is ethylhexylmethoxycrylene.

7. The composition of claim 2 wherein the oxyalklenated organosiloxane emulsifier has the general formula:

8. The composition of claim 7 wherein p is 0, a is 1 to 15, and b is 0 to 10.

9. The composition of claim 8 wherein p is 0, a is 10 and b is 1.

10. The composition of claim 6 further comprising an oxyalkylenated organosiloxane emulsifier that is Lauryl PEG-9 polydimethylsiloxy ethyl dimethicone.

11. The composition of claim 2 wherein the oxyalkylenated organosiloxane emulsifier is crosslinked.
