POLYQUATERNIUM-29

Description

Polyquaternium-29 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 in various skincare and haircare products. Its molecular structure consists of quaternary ammonium groups along a polymer backbone, which gives it its characteristic positive charge.

In skincare applications, Polyquaternium-29 forms a thin, flexible film on the skin's surface, providing a smooth feel and helping to retain moisture. This film-forming property also aids in the even distribution of other active ingredients across the skin. Its cationic nature allows it to adhere well to negatively charged skin and hair surfaces, enhancing its conditioning effects.

In haircare products, Polyquaternium-29 improves manageability, reduces static, and enhances shine without causing build-up. It's particularly effective in leave-in conditioners and styling products due to its ability to form resilient films that resist humidity and mechanical stress.

Polyquaternium-29 is generally well-tolerated and considered safe for use in cosmetic formulations. Its efficacy at low concentrations makes it a cost-effective choice for formulators seeking to improve product performance and sensory attributes.
