Acrylonitrile/Methyl Methacrylate Copolymer

1. Definition Acrylonitrile/Methyl Methacrylate Copolymer:

Acrylonitrile/Methyl Methacrylate Copolymer is a synthetic polymer commonly used in cosmetics as a film-forming agent and binder. It is a copolymer of acrylonitrile and methyl methacrylate, which are monomers that polymerize to form a solid material with excellent film-forming properties.

2. Use:

Acrylonitrile/Methyl Methacrylate Copolymer is used in cosmetics to create long-lasting and water-resistant film on the skin or hair. It is commonly found in makeup products such as mascaras, eyeliners, and lipsticks to improve their staying power and smudge resistance. In hair care products, it is used to provide hold and control while also adding shine to the hair.

3. Usage Acrylonitrile/Methyl Methacrylate Copolymer:

When using cosmetics containing Acrylonitrile/Methyl Methacrylate Copolymer, it is important to follow the manufacturer's instructions for application. Avoid getting the product in contact with the eyes, and in case of irritation or allergic reaction, discontinue use immediately. It is recommended to perform a patch test before using a new product to check for any sensitivities.
