PEG-8/SMDI Copolymer

1. Definition PEG-8/SMDI Copolymer:

PEG-8/SMDI Copolymer is a copolymer composed of polyethylene glycol (PEG-8) and stearyl methacrylate dimethylamine crosspolymer (SMDI). It is commonly used in cosmetics as a film-forming agent and emulsifier.

2. Use:

PEG-8/SMDI Copolymer is primarily used in cosmetics as a film-forming agent, helping to create a smooth and even application of products on the skin. It also acts as an emulsifier, helping to stabilize the formulation and prevent separation of ingredients. Additionally, it can enhance the texture and feel of cosmetic products, providing a silky and luxurious finish.

3. Usage PEG-8/SMDI Copolymer:

PEG-8/SMDI Copolymer is typically found in a variety of cosmetic products such as creams, lotions, serums, and makeup. It is generally considered safe for use in cosmetics, but as with any ingredient, it is important to follow the recommended usage levels provided by the manufacturer. It is also advisable to perform a patch test before using products containing PEG-8/SMDI Copolymer, especially if you have sensitive skin or are prone to allergies.
