Description

(2-Hydroxyethyl)Methylbis[2-[(1-Oxooctadecyl)Oxy]Ethyl]Ammonium Methyl Sulphate is a quaternary ammonium compound with a long-chain fatty acid ester group, widely recognized for its excellent surface-active and conditioning properties. This chemical is a key ingredient in formulations requiring superior emulsification, antistatic effects, and fabric softening. It is primarily utilized by manufacturers in the personal care, textile, and industrial surfactant sectors to enhance product performance and stability.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, 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 Emulsions: Used as an emulsifier and conditioner in creams and lotions to improve skin feel and formulation stability.
• Industrial Antistatic Agents: Applied in plastics, synthetic fibers, and coatings to prevent dust attraction and static discharge.
• Paper Softening & Deinking Aids: Enhances the softness of tissue papers and aids in the removal of inks during paper recycling processes.
• Agricultural Adjuvants: Functions as a surfactant in pesticide and herbicide formulations to improve spreading and adhesion on plant surfaces.
