POLYQUATERNIUM-27

Description

Polyquaternium-27 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This versatile ingredient functions primarily as a film-forming agent, conditioning agent, and fixative. Its molecular structure consists of quaternary ammonium groups attached to a polymer backbone, giving it a positive charge that allows it to adhere effectively to negatively charged surfaces like hair and skin.

In hair care products, Polyquaternium-27 provides excellent conditioning properties, reducing static electricity and improving combability. It forms a protective film on hair strands, enhancing shine and manageability without weighing the hair down. In skincare formulations, it acts as a humectant, helping to attract and retain moisture, thus improving skin hydration.

The ingredient also demonstrates good compatibility with various surfactants, making it suitable for use in cleansing products. Its film-forming properties contribute to the stability and texture of formulations, while its fixative qualities make it valuable in styling products. Polyquaternium-27 is typically used at concentrations ranging from 0.1% to 5%, depending on the specific application and desired effects. It is generally well-tolerated and considered safe for use in cosmetic products.
