Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer

Ammonium acryloyldimethyltaurate/beheneth-25 methacrylate crosspolymer is a synthetic polymer used primarily as an emulsion stabiliser in skincare formulations. It is created through the crosslinking of acrylic monomers and behenic acid derivatives, resulting in a large molecular structure that remains suspended within a product.This ingredient does not penetrate the skin or deliver active benefits directly. Instead, its role is behind-the-scenes: it helps prevent oil and water phases from separating, keeping emulsions stable and creams or lotions uniform in texture throughout their shelf l…

This polymer works by forming a three-dimensional network within an emulsion. The branched structure allows it to absorb and hold both oil and water phases in suspension, preventing them from coalescing or separating. Its large molecular weight means it remains on the surface of the product and does not readily penetrate skin.The ingredient is inert from a skin-active perspective; it functions as a formulation aid rather than a therapeutic agent. Its presence ensures that other actives in the product remain uniformly distributed and properly delivered.

This ingredient requires no special usage guidance, as it is a formulation component rather than an active treatment. It will be present at low concentrations in finished products. Simply use the product as directed by the manufacturer, and you will benefit from the texture stability and even distribution of other actives that this ingredient provides.

Generally well-tolerated in cosmetic formulations at typical use levels. Unsuitable for those with known sensitivity to acrylate polymers, though such sensitivities are rare.
