HYDROXYPROPYL BISSTEARYLDIMONIUM CHLORIDE

Description

Hydroxypropyl bisstearyldimonium chloride is a quaternary ammonium compound widely used in hair care and skincare formulations. This synthetic ingredient functions primarily as a conditioning agent and emollient. Its molecular structure consists of a long hydrocarbon chain attached to a positively charged nitrogen atom, allowing it to interact effectively with hair and skin surfaces.

In hair care products, hydroxypropyl bisstearyldimonium chloride helps to reduce static electricity, improve combability, and enhance overall manageability of hair. It forms a thin, protective film on the hair shaft, which can help to seal the cuticle and reduce moisture loss. In skincare applications, it acts as an emollient, helping to soften and smooth the skin's surface.

This ingredient is particularly beneficial in leave-on treatments and rinse-off conditioners due to its substantivity to keratin. It is generally well-tolerated and considered safe for use in cosmetic formulations at recommended concentrations. However, like many cationic surfactants, it may cause irritation in individuals with sensitive skin or if used in high concentrations. Formulators should consider its compatibility with other ingredients and adjust usage levels accordingly to optimize product performance and safety.
