Abstract
A sunscreen composition includes a sunscreen active, a carrier, and a film former polymer. The sunscreen active may be selected from organic sunscreen actives. The carrier may include an amphiphile monolayer to encapsulate a least a portion of the total amount of the sunscreen active. The film former polymer may include an acrylic film former polymer selected from C1-C30 alkyl (meth)acrylates copolymer. Notably, the sunscreen active may provide enhanced photoprotection at relatively low concentration levels when present with the carrier, including the amphiphile monolayer, and the acrylic film former polymer.
Claims18
A sunscreen composition comprising:
- a sunscreen active including an organic sunscreen active, wherein the organic sunscreen active is present in an amount of greater than zero to less than or equal to 15.0 wt. %, based on the total weight of the sunscreen composition;
- a carrier selected from a micelle, wherein the micelle comprises an oleosome, wherein the oleosome is present in an amount of 0.8 wt. % to less than or equal to 10.0 wt. %, based on the total weight of the sunscreen composition;
- and
- an acrylic film former polymer selected from C1-30 alkyl (meth)acrylates copolymer, wherein the C1-30 alkyl (meth)acrylates copolymer comprises acrylates/C12-22 alkyl methacrylate copolymer, wherein the acrylates/C12-22 alkyl methacrylate copolymer is present in an amount of greater than zero to less than or equal to 2.5 wt. %, based on the total weight of the sunscreen composition;
- and
- wherein the sunscreen composition has a Sun Protection Factor (SPF) greater than or equal to 50.
