Specification :

Sodium Fatty Acid Methyl Ester Sulfonate
RCH( SO3Na) COOCH3 CAS: 93348-22-2
Performance and Application:
Sodium fatty acid methyl ester sulfonate ( MES) is a new anionic surfactant with excellent performances. MES is made from natural oil and fat. It is obtained by esterification, hydrogenation, sulfonation, aging, bleaching and neutralization. MES has good detergency, emulsification and thickening, tolerance to hard water, low irritation and toxicity, good biodegradability, moderate foaming ability, easiness to rinse. For good compatibility with LAS, SLES, AOS, SLS, it is applicable in detergents, personal care, textile, leather chemicals, ore flotation agents and plastic additives, especially in liquid detergent such as shower gel, hand washing, laundry liquid and soap, etc. In shower gel and other liquid detergents, MES can improve detergency and thickening, skin irritation and skin feeling; In washing powder, MES can make products easier to rinse and washed, fabric much softer; In the soap products, MES can greatly improve the re-deposition of calcium.
