Description

N,n-Dimethyl-N,n-Distearylammonium Methosulfate is a quaternary ammonium compound widely used as a cationic surfactant and softener. This material is valued for its excellent substantivity to negatively charged surfaces, providing durable conditioning and antistatic effects. It is a critical ingredient for manufacturers in the textile, personal care, and industrial chemical sectors seeking to impart softness, lubrication, and processability to their products.

Application

• Textile Softener: A primary component in rinse-cycle fabric softeners and dryer sheets, providing a soft, fluffy hand feel to fibers.
• Hair Conditioners: Acts as a key cationic conditioning agent in shampoos, conditioners, and hair masks, improving combability, reducing static, and enhancing shine.
• Industrial Lubricants & Softeners: Used in paper manufacturing, leather processing, and as a softener and lubricant for synthetic fibers during spinning and weaving.
• Antistatic Agent: Imparts antistatic properties to plastics, synthetic textiles, and other materials prone to static charge buildup.
• Emulsifier & Dispersant: Serves as an emulsifying agent in various formulations and aids in pigment and filler dispersion.
