ACRYLATES/LAURETH-25 METHACRYLATE COPOLYMER.

Valuable / VISCOSITY CONTROLLING

This associative rheology modifier enhances formula stability and controls viscosity, creating a desirable texture. It also exhibits antimicrobial properties at concentrations of 1% or higher.

Summary

viscosity controlling emulsion stabilising

Science

Mechanism of Action

Functions as an associative rheology modifier, thickening formulations through chain entanglement in the aqueous phase. Its hydrophobic laureth-25 side chains also form a 3D network by associating with other hydrophobic components, stabilizing emulsions.
