  • Patent number: 8993112
    Abstract: Polymeric particles comprising a polymeric matrix that has been formed from a blend of monomers comprising a first monomer which is an ethylenically unsaturated ionic monomer and a second monomer which is an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C., wherein secondary particles are distributed throughout the matrix, in which the secondary particles comprise a hydrophobic polymer that has been formed from an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C. and optionally other monomers, which hydrophobic polymer is different from the polymeric matrix. Also claimed is a process for preparing particles. The particles have improved shatter resistance. Preferably the polymeric particles comprise an active ingredient, especially a colorant.

  • Publication number: 20040156814
    Abstract: Aqueous compositions comprising a cationic copolymer with a molecular weight in the range of 30,000 to 300,000 and a high molecular weight alcohol, for example at least one C20-C40 alcohol, and the use of said aqueous compositions to prepare cosmetic eye-care formulations, for example mascara or eyeliner, are described. The eye-care formulations give outstanding shine as well as durability to rub-off to the cosmetic eye-care compositions.
