Ammonium Acryloyldimethyltaurate/Carboxyethyl Acrylate Crosspolymer

Ammonium acryloyldimethyltaurate/carboxyethyl acrylate crosspolymer is a synthetic polymer used primarily as a viscosity controlling agent in skincare products. It belongs to a class of crosslinked acrylic polymers designed to thicken formulations and create a stable, uniform texture.

This ingredient works behind the scenes in cosmetic formulations rather than directly on the skin. Its role is to give creams, gels and serums their desired consistency, helping them spread evenly and feel pleasant during application. It is not an active skincare ingredient targeting specific skin concerns.

This polymer functions as a thickening agent by forming a three-dimensional network within the formulation. When incorporated into a skincare product, its crosslinked structure absorbs and holds water, increasing the overall viscosity and giving the product body and stability.

The polymer does not penetrate the skin or interact with skin biology in a meaningful way. Instead, it remains largely on the surface, helping to deliver other active ingredients while maintaining the product's integrity from manufacture through to use.

This ingredient requires no special usage consideration from the consumer. It is used at a formulation level determined by manufacturers to achieve the desired product texture. Simply use the product as directed; the polymer will work invisibly to maintain consistency and aid in delivering other active ingredients.
