AMMONIUM STYRENE/MA COPOLYMER

Description

Ammonium Styrene/MA Copolymer is a synthetic polymer widely used in cosmetic and personal care formulations. This ingredient is a copolymer composed of styrene and maleic acid monomers, neutralized with ammonium. Its primary function is as a film-forming agent, providing resilience and durability to various skincare and haircare products.

In skincare applications, Ammonium Styrene/MA Copolymer contributes to the formation of a flexible, water-resistant film on the skin's surface. This film helps to improve the longevity of other active ingredients and can enhance the overall efficacy of sunscreens, moisturizers, and makeup products. The polymer's film-forming properties also assist in creating a smooth, even application of cosmetic products.

In hair care formulations, this copolymer aids in styling and hold, providing a lightweight, non-sticky feel while maintaining hair shape and texture. It is particularly effective in humidity-resistant hair products, helping to prevent frizz and maintain hairstyles in challenging environmental conditions.

Ammonium Styrene/MA Copolymer is generally considered safe for use in cosmetic products and is compatible with a wide range of other ingredients. Its versatility and performance make it a valuable component in many modern skincare and haircare formulations.
