STEARDIMONIUM HYDROXYPROPYLTRIMONIUM CHORIDE
Description
Steardimonium Hydroxypropyltrimonium Chloride is a quaternary ammonium compound widely used in personal care and cosmetic formulations. This multifunctional ingredient serves primarily as a conditioning agent and anti-static additive in hair care products, skin care formulations, and various cosmetics.
The compound is derived from stearic acid and features a positively charged hydrophilic head group attached to a hydrophobic tail. This unique structure allows it to adhere to negatively charged surfaces, such as hair and skin, providing excellent conditioning and softening properties. In hair care products, it helps to detangle, reduce frizz, and improve manageability without causing buildup or weighing down the hair.
Steardimonium Hydroxypropyltrimonium Chloride demonstrates good compatibility with other ingredients and stability across a wide pH range. It is effective at low concentrations, typically used at 0.5-2% in formulations. The ingredient also exhibits mild antimicrobial properties, contributing to product preservation.
While generally considered safe for cosmetic use, individuals with sensitive skin should perform patch tests before prolonged use. As with any quaternary compound, it may cause eye irritation if used in high concentrations or if it comes into direct contact with the eyes.
