POLYETHYLENE/ISOPROPYL MALEATE/MA COPOLYOL.

Valuable CAS 224580-87-4 / EMULSION STABILISING, VISCOSITY CONTROLLING

POLYETHYLENE/ISOPROPYL MALEATE/MA COPOLYOL is a multifunctional synthetic polymer primarily recognized for its roles as an emulsifier, surfactant, and viscosity modifier. Its chemically inert profile and substantial molecular weight contribute to high formulation stability and excellent skin compatibility across various precision skincare applications.

Summary

Emulsifying Surfactant Viscosity Controlling Emulsion Stabilizing Wetting Agent

Science

Mechanism of Action

This ingredient functions by reducing interfacial tension, effectively acting as a surfactant and emulsifier to stabilize complex formulations of disparate phases. Additionally, it serves as a viscosity controlling agent, contributing to the desired texture and spreadability of products. Its polymeric structure also supports emulsion stability by enabling a lower free energy state within the formulation.
