Solution Overview

Problem

Natural-based products in personal care and pharmaceutical industries face challenges with non-pleasant sensorial properties from vegetable oils and waxes, requiring additional ingredients like silicones to enhance sensory profiles, but existing silicone-modified fatty carboxylic acid compounds have limitations in viscosity, odor, and sensorial benefits.

Innovation Solution

A method of reacting cyclic ether silicones with epoxy groups with sapucainha oil-derived fatty carboxylic acids in the presence of a catalyst to produce silicone-modified fatty esters, which can be incorporated into cosmetic and pharmaceutical compositions, improving sensorial feelings and reducing viscosity and odor.
