ACTIVE INGREDIENT MICROPARTICLES |
摘要 |
The present invention concerns polymeric-enveloped microparticles including at least one HASE type acrylic copolymer, at least one solid-liquid phase change material with a phase transition temperature ranging from 20 to 90° C., and at least one active agent. In particular, the microparticles include at least one HASE type acrylic copolymer including at least one anionic monomer with a polymerizable vinyl group and a carboxyl group, at least one non-ionic hydrophobic monomer with a polymerizable vinyl group, and at least one alkoxylated associative macromonomer with a polymerizable vinyl group and a hydrophobic hydrocarbon chain. |
