Patent ID: 8765967

Claim:
A sunscreen composition, comprising (i) cosmetic adjuvants and additives and (ii) microcapsules with UV filter activity made by a sol-gel method, wherein at least one type of crosslinkable chromophore with UV-A and/or UV-B and/or UV-C filter activity and optionally at least one type of crosslinkable monomer which does not have UV-A and/or UV-B and/or UV-C filter activity are subjected to a crosslinking reaction in the absence of non-crosslinkable chromophores with UV-A and/or UV-B and/or UV-C filter activity, wherein the at least one type of crosslinkable chromophore with UV-A and/or UV-B and/or UV-C filter activity is a monomer of the formula M(R) n (P) m (Q) q , wherein M is a metallic or semi-metallic element, R is a hydrolysable group, P is a chromophore with UV-A, UV-B and/or UV-C filter activity, Q is a non hydrolysable group, n is 2 or 3, m is 1 or 2 and q is 0 or 1, and n+m+q=4, and wherein the chromophores are covalently bonded to the polymeric matrix of the microcapsule.
