POLYQUATERNIUM-43

Description

Polyquaternium-43 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This versatile ingredient functions primarily as a film-forming agent, conditioning enhancer, and hair fixative. Its chemical structure consists of quaternary ammonium groups along a polymer backbone, which gives it its characteristic positive charge and affinity for negatively charged surfaces like hair and skin.

In skincare products, Polyquaternium-43 acts as a humectant, helping to attract and retain moisture, thereby improving skin hydration. It also forms a protective film on the skin's surface, which can provide a smooth feel and help reduce transepidermal water loss. In hair care applications, it excels at detangling, reducing static, and improving manageability without causing build-up.

Polyquaternium-43 is compatible with a wide range of other cosmetic ingredients and remains stable across various pH levels. Its low molecular weight allows for easy incorporation into formulations without significantly affecting viscosity. Safety assessments have shown it to be non-irritating and well-tolerated by most individuals. This ingredient is particularly valuable in leave-on products, where its conditioning and film-forming properties can provide long-lasting benefits.
