Polyquaternium 39

Description

Polyquaternium-39 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This water-soluble ingredient belongs to the broader family of polyquaternium compounds, known for their positive electrical charge and affinity for negatively charged surfaces like hair and skin.

In skincare and haircare products, Polyquaternium-39 functions primarily as a film-forming agent, conditioning agent, and anti-static ingredient. Its unique molecular structure allows it to form a thin, protective film on the skin and hair, enhancing moisture retention and improving the overall feel of the product.

Polyquaternium-39 is particularly effective in leave-on formulations such as lotions, creams, and hair styling products. It helps to reduce frizz in hair care applications and can improve the spreadability and texture of skincare products. This ingredient also exhibits good compatibility with anionic surfactants, making it suitable for use in cleansing formulations.

While generally considered safe for topical use, as with any cosmetic ingredient, some individuals may experience sensitivity. It is always recommended to perform a patch test before incorporating new products containing Polyquaternium-39 into a skincare or haircare routine.
