POLYQUATERNIUM-2

Description

Polyquaternium-2 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 in hair care and skincare products. Its molecular structure consists of repeating quaternary ammonium compounds, which impart a positive charge to the polymer.

In hair care applications, Polyquaternium-2 effectively reduces static electricity, improves combability, and enhances the overall manageability of hair. It forms a thin, protective film on the hair shaft, which helps to seal the cuticle and prevent moisture loss. This film-forming property also contributes to increased shine and smoothness.

In skincare formulations, Polyquaternium-2 acts as a humectant and skin conditioner. It helps to retain moisture within the skin, promoting hydration and improving skin texture. The ingredient's positive charge allows it to adhere well to negatively charged skin and hair surfaces, ensuring prolonged efficacy.

Polyquaternium-2 is compatible with a wide range of other cosmetic ingredients and remains stable across various pH levels. It is particularly effective in leave-on products and rinse-off formulations, making it a valuable component in shampoos, conditioners, styling products, lotions, and creams.
