POLYQUATERNIUM-20

Description

Polyquaternium-20 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This versatile ingredient functions primarily as a conditioning agent and film-former, offering significant benefits in hair and skin care products. Its chemical 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 applications, Polyquaternium-20 excels at improving manageability, reducing static, and enhancing overall feel. It forms a lightweight, protective film on hair strands, providing moisture retention and increased combability without causing buildup. For skincare, it acts as a humectant and film-former, helping to maintain skin hydration and create a smooth, supple texture.

Polyquaternium-20 is compatible with a wide range of ingredients, making it a versatile choice for formulators. It performs well in various pH ranges and is stable in the presence of most common cosmetic ingredients. This polymer is particularly effective in leave-on products and rinse-off formulations, where its conditioning properties can be fully utilized. Its low irritation potential makes it suitable for use in products designed for sensitive skin types.
