Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer

1. Definition Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer:

Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer is a synthetic polymer used in cosmetics as a film-forming agent and binder. It is a copolymer of acrylonitrile, methacrylonitrile, and methyl methacrylate, which are monomers that combine to form a durable and flexible film on the skin or hair.

2. Use:

Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer is commonly used in cosmetics to improve the texture, longevity, and adherence of products such as lipsticks, mascaras, and hair styling products. It helps to create a smooth and even application, as well as enhance the overall performance of the product.

3. Usage Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer:

When using cosmetics containing Acrylonitrile/Methacrylonitrile/Methyl Methacrylate Copolymer, it is important to follow the manufacturer's instructions for application. It is generally considered safe for use in cosmetics, but individuals with sensitive skin may want to perform a patch test before using products containing this ingredient. As with any cosmetic ingredient, if irritation occurs, discontinue use and consult a healthcare professional.
