Abstract
The present invention relates to topical compositions comprising panthenol, hydroxyacetophenone and a micronized UV filter.
Claims6
A topical composition consisting of:
- 1 to 5 wt. %, based on total weight of the composition, of panthenol,
- 0.5 to 5 wt. %, based on total weight of the composition, of p-hydroxyacetophenone,
- 0.3 to 10 wt. %, based on total weight of the composition, of methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT) as a micronized UV filter, and
- optionally at least one additional UV filter selected from the group consisting of butyl methoxydibenzoylmethane, octocrylene and ethylhexyl salicylate,
- wherein the micronized UV filter is present as an aqueous dispersion containing the particles of the micronized UV filter optionally with a C8-16 alkyl poly-glucoside,
- wherein the micronized UV filter has a mean particle size distribution Dv50 as determined by light scattering of less than 200 nm,
- wherein the composition is an oil-in-water (O/W) emulsion consisting of an oily phase dispersed in an aqueous phase, wherein the aqueous phase consists of the micronized UV filter in the presence of a phosphate ester emulsifier as an O/W emulsifier, and
- wherein the topical composition exhibits less transfer of the composition to a glass surface as compared to an identical composition that does not contain the panthenol, the p-hydroxyacetophenone and the MBBT.
