SODIUM METHOXY PEG-16 MALEATE/STYRENE SULFONATE COPOLYMER

Description

Sodium Methoxy PEG-16 Maleate/Styrene Sulfonate Copolymer is a multifunctional synthetic ingredient widely used in skincare and cosmetic formulations. This water-soluble copolymer serves as a film-forming agent, providing a protective barrier on the skin's surface. Its unique chemical structure allows it to form a thin, flexible film that helps to improve the texture and feel of various products.

In skincare applications, this copolymer enhances the stability and spreadability of formulations, particularly in sunscreens and moisturizers. It aids in the even distribution of active ingredients and can improve the water resistance of products. The ingredient also functions as a viscosity modifier, helping to achieve desired product consistency.

Sodium Methoxy PEG-16 Maleate/Styrene Sulfonate Copolymer is compatible with a wide range of cosmetic ingredients, making it versatile for use in different formulations. It is particularly effective in oil-in-water emulsions and can contribute to the overall sensory experience of a product by providing a smooth, non-tacky feel.

While generally considered safe for topical use, as with any synthetic ingredient, patch testing is recommended for individuals with sensitive skin or known allergies to ensure compatibility.
