POLYMERIC ADHESIVE AGENTS ARE DISCLOSED WHICH COMPRISE POLYSILOXANE GRAFTED POLYMERS WHEREIN: (A) THE POLYMERS ARE MADE BY POLYMERIZATION OF POLYSILOXANE-CONTAINING MONOMERS AND NON-POLYSILOXANE-CONTAINING MONOMERS, TYPICALLY BY FREE RADICAL POLYMERIZATION; (B) THE ADHESIVE AGENT HAS A WEIGHT AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 20,000 AND CONTAINS FROM ABOUT 1TO ABOUT 50, BY WEIGHT, OF POLYSILOXANE-CONTAINING MONOMER; AND (C) THE WEIGHT PERCENTAGE OF SILICON PRESENT AS UNREACTED POLYSILOXANE-CONTAINING MONOMER AND SILICONE-GRAFTED POLYMER HAVING A VISCOSITY AT 25°C OF BELOW ABOUT 10,000,000 CENTISTOKES BASED ON THE TOTAL SILICON PRESENT AS UNREACTED SILICON MONOMER AND POLYSILOXANE-GRAFTED POLYMER IS ABOUT 15OR LESS. ALSO, THE ADHESIVE AGENT CONTAINS NO MORE THAN ABOUT 4BY WEIGHT, OF UNREACTED POLYSILOXANE-CONTAINING MONOMER AND POLYSILOXANE-GRAFTED POLYMER HAVING A VISCOSITY AT 25°C OF BELOW ABOUT 10,000,000 CENTISTOKES. COSMETIS COMPOSITIONS CONTAINING SUCH ADHESIVE AGENTS ARE ALSO DISCLOSED.
