POLYQUATERNIUM-24

Description

Polyquaternium-24 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This water-soluble ingredient belongs to the broader family of polyquaternium compounds, known for their positive electrical charge and ability to form films on hair and skin surfaces.

In skincare products, Polyquaternium-24 functions primarily as a conditioning agent and film-former. It adheres well to negatively charged skin and hair surfaces, providing a smooth, protective layer that enhances moisture retention and improves texture. This polymer is particularly effective in leave-on formulations, where it can help reduce static and improve the overall feel of the product.

Polyquaternium-24 is also valued for its ability to enhance the delivery of other active ingredients in formulations. Its cationic nature allows it to act as a carrier for various beneficial compounds, potentially improving their efficacy and longevity on the skin or hair.

While generally considered safe for use in cosmetics, as with all ingredients, some individuals may experience sensitivity. It's typically used in concentrations ranging from 0.1% to 2% in finished products, depending on the specific formulation and desired effects.
