Water-based nail-polish composition |
摘要 |
The water-based nail-polish composition includes a mixture of at least one water-based suspension (A) of hard nanoparticles of an acrylic polymer at a glass transition temperature that is greater than or equal to 55° C., in combination with at least one coalescent and/or plasticizing solvent of the polymer; and at least one water-based suspension (B) of nanoparticles of acrylic monomers, partially cross-linked, that have a film formation temperature of less than 15° C. The water-based composition can also contain a solution (C) of an acrylic polymer of low molecular weight that is less than approximately 20,000, with a high acid value, neutralized to a pH of between 7 and 8.5, approximately. |

1. A water-based nail-polish composition, comprising a mixture of:
a water-based suspension (A) of hard nanoparticles of a size from 40 to 80 nm of acid and (meth) acrylic esters/styrene polymers having a film formation temperature (TMF) of 60° C. and a glass transition temperature of 64° C., in combination with at least one coalescent and/or plasticizing solvent of said polymer, said polymer having a molecular weight of more than approximately 200,000, said hard nanoparticles being 46% by weight of said suspension(A), and said hard nanoparticles between 12 and 24% by weight of said water-based nail polish composition; and a water-based suspension (B) of nanoparticles of a size from 50 to 80 nm of acrylic, pre-cross-linked monomers that have a film formation temperature of 10° C. and a glass transition temperature of 46° C., said nanoparticles having a cross-linking level of between 0.5 and 5%, said nanoparticals being 45% by weight of said suspension(B), and said nanoparticles being between 8 and 16% by weight of said water-based nail polish composition. |
