Description

Bis(2-Hydroxyethyl)Methyl(Octadecyl)Ammonium Methyl Sulphate is a quaternary ammonium compound (quat) valued for its potent cationic surfactant properties and excellent fabric softening capabilities. This compound is a key active ingredient in the formulation of high-performance industrial and institutional fabric softeners, conditioners, and antistatic agents. It is primarily utilized by manufacturers in the textile, personal care, and specialty chemical industries seeking effective and versatile cationic agents.

Application

• Fabric Softener Concentrates: Serves as a primary active ingredient in liquid and dryer sheet formulations for domestic and industrial laundry applications, providing softness and reducing static cling.
• Hair Conditioners & Cosmetics: Used as a conditioning agent in rinse-off and leave-in hair care products, shampoos, and skin creams to impart softness and manageability.
• Industrial Textile Auxiliaries: Functions as a softening and antistatic agent in textile finishing processes for synthetic and natural fibers.
• Antistatic Agents: Incorporated into formulations for plastics, synthetic fibers, and electronics manufacturing to dissipate static charge.
• Biocide & Disinfectant Synergist: Can be used in combination with other antimicrobial agents in certain disinfectant and sanitizer formulations to enhance efficacy.
• Emulsifier and Dye Leveling Agent: Acts as an auxiliary agent in dyeing processes and in the preparation of stable emulsions for various industrial applications.
