Styrene/ Acrylamide Copolymer

1. Definition Styrene/ Acrylamide Copolymer:

Styrene/Acrylamide Copolymer is a synthetic polymer used in cosmetics as a film-forming agent and viscosity increasing agent. It is a copolymer of styrene and acrylamide, two monomers that are combined to create a polymer with unique properties for use in cosmetic formulations.

2. Use:

Styrene/Acrylamide Copolymer is commonly used in cosmetics as a film-forming agent to create a barrier on the skin or hair, helping to lock in moisture and protect against environmental stressors. It is also used as a viscosity increasing agent to thicken the texture of cosmetic products, providing a luxurious feel and improved application.

3. Usage Styrene/ Acrylamide Copolymer:

When using cosmetics containing Styrene/Acrylamide 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 or allergies should 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.
