Acrylonitrile/Methyl Methacrylate/Vinylidene Chloride Copolymer

Acrylonitrile/Methyl Methacrylate/Vinylidene Chloride Copolymer is a synthetic polymer created by combining three different monomers through a chemical polymerisation process. It is a film-forming ingredient, meaning it creates a thin, continuous layer on the skin's surface when applied.

This ingredient is used sparingly in skincare formulations (appearing in roughly 0.1% of products) primarily to improve texture, stability, and the sensory feel of a product. It is a technical ingredient rather than an active treatment component.

As a copolymer, this ingredient functions by forming a flexible polymer film across the skin's surface. This film is thin enough to allow skin to breathe normally whilst providing a protective, smoothing effect.

The ingredient does not penetrate the skin barrier; instead, it remains on the surface, where it can help reduce the appearance of texture irregularities and support the delivery or performance of other formula components.

Products containing this copolymer should be applied as directed by the manufacturer. Because it is a texture and stability agent rather than an active ingredient, its efficacy depends on the broader formulation. Use consistently as part of your regular routine for best results with the product's intended sensory profile and stability.
