METHOD FOR FORMULATING ACTIVE FRAGRANCE INGREDIENTS IN ORDER TO PROTECT THEM AND INCREASE THEIR REMANENCE

摘要

Claimed is a new method for formulating active fragrance ingredients in such a way as to protect them and to slow their evaporation. It relies upon the use of thickening acrylic emulsions containing hydrophobic groups at a pH above five.These emulsions allow the active fragrance ingredients to be trapped by encapsulation in order to promote their protection against the environment, while slowing their release kinetics, which translates into the perfume's increased effectiveness (remanence phenomenon).
