Styrene/Stearyl Methacrylate Crosspolymer

1. Definition Styrene/Stearyl Methacrylate Crosspolymer:

Styrene/Stearyl Methacrylate Crosspolymer is a synthetic polymer used in cosmetics as a thickening agent and film former. It is a crosslinked copolymer of styrene and stearyl methacrylate, which helps to improve the texture and stability of cosmetic products.

2. Use:

Styrene/Stearyl Methacrylate Crosspolymer is commonly used in a variety of cosmetic products such as creams, lotions, and makeup products. It helps to create a smooth and creamy texture, improve spreadability, and enhance the overall performance of the product. Additionally, it can also act as a suspending agent, helping to disperse pigments and other ingredients evenly throughout the formulation.

3. Usage Styrene/Stearyl Methacrylate Crosspolymer:

When using products containing Styrene/Stearyl Methacrylate Crosspolymer, it is important to follow the manufacturer's instructions and guidelines. It is generally considered safe for use in cosmetics, but some individuals may be sensitive or allergic to certain ingredients, so it is recommended to perform a patch test before using a new product. Additionally, it is important to avoid getting the product in contact with the eyes or mucous membranes, and to discontinue use if any irritation or adverse reactions occur.
