Description

[2-Hydroxy-3-[(1-Oxoisooctadecyl)Oxy]Propyl]Trimethylammonium Chloride is a quaternary ammonium compound with a long-chain fatty acid ester linkage, functioning as a cationic surfactant and conditioning agent. Its molecular structure provides excellent substantivity to negatively charged surfaces, making it a key ingredient for imparting softness and antistatic properties. This chemical is primarily utilized by manufacturers in the personal care, textile, and specialty chemical industries for formulating high-performance conditioners, fabric softeners, and emulsifiers.

Application

• Hair Conditioners & Rinse-Off Products: Acts as a primary cationic conditioning agent, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Laundry Care: Imparts a soft, fluffy hand feel to textiles and reduces static cling in dryer sheets and liquid softeners.
• Skin Care & Creams: Used as an emulsifier and skin-conditioning agent in lotions and creams to enhance skin feel and product stability.
• Industrial Surfactants & Emulsifiers: Serves as a cationic emulsifier for oil-in-water systems in various industrial applications.
• Antistatic Agents: Applied in formulations for plastics, textiles, and electronics to dissipate static electricity.
• Biocide & Preservative Potentiator: Can enhance the efficacy of certain preservative systems due to its cationic nature and membrane-disrupting potential.
