BEHENYL METHACRYLATE/ETHYLAMINE OXIDE METHACRYLATE COPOLYMER.

Valuable / ANTIFOAMING, FILM FORMING, HAIR FIXING

A sophisticated amphiphilic polymer utilized to maintain the structural integrity of liquid formulations by suppressing unwanted aeration. Its dual-natured molecular structure allows it to refine product texture and ensure a smooth, bubble-free application.

antifoaming defoaming texture modifier

Science

This copolymer operates by migrating to the liquid-gas interface within a formula. Its hydrophobic behenyl chains and polar amine oxide groups work in tandem to disrupt surface tension at the site of air bubbles, causing them to collapse and preventing the formation of micro-foam during the manufacturing or application process.
