Description

Sodium Fatty Acid Methyl Ester Sulfonate
RCH(SO3Na)COOCH3���CAS:*********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.

Notes:
The Krafft point of MES is *7?*0 degree so the solubility at low temperature is poor.
It is easy to hydrolyse resulting di-sodium salt when contacts with acid, alkali and high temperature.

Direction for use:
MES(*0%) is viscous liquid above �*0 degree, �and becoming gel below *0?. It would be layered for long-time storage in low temperature.
Solid MES is flake or powder at normal temperature, and easily bond when store above *5degree.
MES(*0%,*5%) is soluble in water above *0 degree. For solid product, it is suggested to use with hot water (*0~*0 degree);
Recommended use (as **0% a.m): 2~4%(liquid detergent), 3~8%(washing powder), 2~8% (liquid laundry detergent)
