Title
(EN) BLEED-RESISTANT COLORED MICROPARTICLES AND SKIN CARE COMPOSITIONS COMPRISING THEM
(FR) MICROPARTICULES COLORÉES RÉSISTANTES AU SAIGNEMENT ET COMPOSITIONS DE SOIN DE LA PEAU COMPRENANT CELLES-CI
Abstract
(EN)
An embodiment concerns a skin care composition comprising at least one colorant, wherein said colorant is entrapped in at least one microparticulate matrix polymer, wherein the entrapment of said colorant in said microparticulate matrix polymer forms a microencapsulated colorant, wherein said microparticulate matrix polymer comprises: a. at least one first polymer formed from a mixture of monomers comprising at least one first monomer that is an ethylenically unsaturated ionic monomer and at least one second monomer that is an ethylenically unsaturated hydrophobic monomer capable of forming a homopolymer with a glass transition temperature of from -40 to 50 deg C; and b. at least one second polymer formed from a mixture of monomers comprising at least one first monomer that is an ethylenically unsaturated ionic monomer and at least one second monomer that is an ethylenically unsaturated hydrophobic monomer capable of forming a homopolymer with a glass transition temperature greater than 50 deg. C; whereiri said microparticulate matrix polymer further comprises secondary particles distributed throughout said microparticulate matrix polymer, wherein said secondary particles comprise a hydrophobic polymer formed from at least one ethylenically unsaturated hydrophobic monomer capable of forming a homopolymer with a glass transition temperature greater than 50 deg. C; preferably said microencapsulated colorant is present in an amount of from 0.1 to 70% by weight of the composition; preferably said composition further comprises a cosmetically tolerable carrier or adjuvant.
