Science
Mechanism of Action
As a quaternary ammonium compound, STEAROYL PG-TRIMONIUM CHLORIDE possesses a positive charge, enabling it to bind to negatively charged surfaces, such as the keratin found in hair and skin. This electrostatic interaction contributes to its conditioning properties by creating a smoother surface texture and offering antistatic effects. Furthermore, it acts as an emulsifier, stabilizing formulations by blending immiscible oil and water components, and may exhibit mild antimicrobial attributes.
