Used as a cationic surfactant and emulsifier in cosmetic and personal care formulations. It stabilizes emulsions in skin creams and lotions by reducing surface tension between oil and water phases. Enhances conditioning properties in hair care products such as conditioners and masks by promoting deposition of beneficial ingredients onto hair fibers. Exhibits good biocompatibility and is often selected for sensitive skin formulations due to its mild nature. Also functions as an antistatic agent, helping reduce static buildup in rinse-off and leave-on products. Its structure allows for biodegradability, making it suitable for eco-friendly product lines.
