Claim Text:
1. A cosmetic skin covering sheet which comprises a patch containing a cosmetic material for application to the skin or a cosmetic formulation which forms the cosmetic skin covering sheet in-situ upon topical application of the cosmetic formulation onto the skin, and the said cosmetic skin covering sheet is produced by a reaction selected from a condensation reaction, a hydrosilylation reaction, a free-radical polymerization reaction, a ring-opening polymerization reaction and combinations thereof, wherein the reaction is conducted in the presence of (i) at least one ionic silicone having the general formula: wherein: M M M D D D T T T Q=SiO where R where R where R where the subscripts a, b, c, d, e, f, g, h, i, j are zero or positive subject to the following limitations: the sum a+b+c+d+e+f+g+h+i+j is greater than or equal to 2 and less than or equal to 6000, and b+e+h is greater than 0; and (ii) at least one compound selected from a hydrosilylation effective component, a condensation effective component, free radical polymerization effective component and a ring-opening polymerization component; with the proviso that when R 7 , R 14 and R 18 are hydrogen then the hydrosilylation effective component is selected from a vinyl silicone and hydrosilylation effective catalyst, and when R 7 , R 14 and R 18 are unsaturated monovalent radicals the hydrosilylation effective component is selected from a hydride silicone and hydrosilylation effective catalyst.
