Description

(3-Decyloxy-2-Hydroxypropyl)Bis(2-Hydroxyethyl)Methylammonium Methyl Sulphate is a quaternary ammonium compound (quat) with a complex, multi-functional structure, making it a highly effective cationic surfactant and conditioning agent. Its unique molecular architecture provides excellent substantivity to negatively charged surfaces, delivering superior softening, antistatic, and emulsifying properties. This specialty chemical is essential for formulators in the personal care, textile, and industrial cleaning sectors seeking high-performance ingredients for demanding applications.

Application

• Hair Conditioners & Rinse-Off Products: Acts as a primary cationic conditioning agent, providing excellent detangling, smoothness, and manageability to hair.
• Fabric Softeners & Laundry Care: Imparts a soft hand feel, reduces static cling, and improves fabric wearability in both liquid and dryer sheet formulations.
• Skin Care & Creams: Used as an emulsifier and skin-conditioning agent in leave-on and rinse-off formulations for its softening and smoothing effects.
• Industrial & Institutional (I&I) Cleaners: Serves as a surfactant and antistatic agent in floor polishes, car wash formulas, and hard surface cleaners.
• Textile Auxiliaries: Employed as a softening and antistatic finishing agent for natural and synthetic fibers during processing.
• Agricultural Adjuvants: Can function as a compatibility agent or deposition aid in pesticide and herbicide formulations.
