STYRENE METHYLTRIMONIUM CHLORIDE CROSSPOLYMER

Description

Styrene Methyltrimonium Chloride Crosspolymer is a synthetic polymer that serves multiple functions in skincare and cosmetic formulations. This versatile ingredient acts primarily as a film-forming agent, creating a protective barrier on the skin or hair surface. Its unique structure, composed of cross-linked styrene and quaternary ammonium compounds, allows it to form a flexible, breathable film that can enhance product texture and improve the longevity of other active ingredients.

In skincare applications, Styrene Methyltrimonium Chloride Crosspolymer contributes to improved moisturization by reducing transepidermal water loss. It also aids in the even distribution of other ingredients across the skin's surface, promoting better product efficacy. The polymer's positive charge enables it to adhere well to negatively charged skin and hair surfaces, making it particularly useful in leave-on products and hair conditioners.

Safety assessments have shown this ingredient to be non-irritating and well-tolerated by most skin types. Its molecular size prevents penetration into deeper skin layers, minimizing the risk of systemic absorption. While not naturally derived, Styrene Methyltrimonium Chloride Crosspolymer is considered stable and effective in a wide range of formulations, from serums to creams and hair care products.
