POLYQUATERNIUM-85

Description

Polyquaternium-85 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This quaternary ammonium compound belongs to the polyquaternium family, known for its versatile applications in hair and skin care products. Its chemical structure consists of a long chain of repeating units with positively charged nitrogen atoms, giving it unique properties beneficial for various formulations.

In skincare, Polyquaternium-85 functions primarily as a film-forming agent and conditioning ingredient. It forms a thin, protective layer on the skin's surface, helping to improve moisture retention and provide a smooth feel. This polymer also exhibits excellent substantivity, allowing it to adhere well to the skin and hair, enhancing the longevity of product effects.

Polyquaternium-85 is particularly valued for its ability to improve the texture and stability of formulations. It acts as an effective thickening agent and emulsion stabilizer, contributing to the desired consistency of creams, lotions, and gels. Additionally, its cationic nature allows it to neutralize static charge, making it useful in hair care products for reducing frizz and improving manageability.
