Description

(Z)-2-(Methyloleylamino)Ethanesulphonic Acid CAS NO 97-80-3 is a high-purity, amphoteric surfactant and specialty chemical intermediate. This compound is valued for its unique combination of oleyl-derived hydrophobicity and sulfonic acid functionality, offering excellent emulsifying, wetting, and solubilizing properties. It is primarily sought by manufacturers in the personal care, textile processing, and specialty chemical synthesis industries for formulating high-performance products.

Application

• Personal Care Formulations: Acts as a mild surfactant and emulsifier in shampoos, conditioners, and skin cleansers, providing rich lather and conditioning benefits.
• Textile Auxiliaries: Used as a leveling agent, softener, and dyeing assistant in the processing of natural and synthetic fibers.
• Industrial Emulsifiers: Serves as a key component in the production of cutting oils, metalworking fluids, and pesticide emulsions.
• Chemical Synthesis: Functions as a versatile intermediate for the synthesis of betaine-type amphoteric surfactants and other specialty chemicals.
• Enhanced Oil Recovery (EOR): Investigated for use as a surfactant in chemical flooding to improve oil displacement efficiency.
• Lubricant Additives: Imparts anti-wear and extreme pressure properties when incorporated into lubricant formulations.
