AI Technical Summary

Technical Problem

The perfume, cosmetic, and cleaning industries require environmentally friendly and safer compositions for dispersing fat-soluble compounds in aqueous phases, while maintaining clarity and minimizing the use of dispersants.

Method used

A dispersant composition comprising alkyl polyglycoside and diesters of formula (B) is used to disperse fat-soluble compounds in an aqueous phase, achieving a synergistic effect that allows for transparent emulsions with reduced dispersant usage.

Benefits of technology

The composition achieves clear emulsions with a lower dispersant-to-fat-soluble compound ratio, using natural, biodegradable ingredients, and supports high concentrations of fat-soluble compounds.

Abstract

The present application relates to a dispersant composition comprising at least one alkyl polyglycoside and a diester of the following formula (B), wherein the mass ratio of the mass portion of the alkyl polyglycoside to the mass portion of the diester of formula (B) is 7.4 to 18.0: TIFF2023516644000010.tif37170 (in formula (B), R and R' represent the same or different alkyl groups, which are linear or branched and contain 1 to 10 carbon atoms; Z represents a group of formula -(C n H 2n )- is a linear or branched group, and n is an integer of 1 to 10.
