Chemistry, Properties & Perfumer Guide

The Chemistry

This is a synthetic polymer formed through the reaction of methyloxirane with oxirane, subsequently etherified with a tetrafunctional amine alcohol. The resulting branched polymer exhibits specific rheological properties. The 4:1 ratio indicates the stoichiometry between the polyether backbone and the branching agent. Such polymers are typically synthesized through controlled anionic polymerization followed by functional group transformations.
