Sodium fatty acid methyl ester sulfonate MES
CAS Number: 4062-78-64016-24-4
Description:
MES is derived from renewable palm oil and is a biodegradable green surfactant. At the same time, it has a higher detergency, compared with traditional anionic surface active, the amount of decontamination required to achieve the same is lower, helping to reduce the use of organic matter in detergents and carbon dioxide emissions. MES also has some other excellent properties, such as excellent resistance to hard water and low skin irritation. MES is a new type of surfactant that is green, efficient, and safer for people and the environment, and meets the requirements of sustainable development. When MES is used in powder detergents, it can improve the formula's washing power and hard water resistance, help reduce the amount of zeolite and other water softeners, reduce the deposition of inorganic salts on clothing, and make clothing softer and less prone to graying. However, MES has the problem of being easily hydrolyzed under high alkaline conditions. In recent years, the application of MES in washing powder has achieved technological breakthroughs. It has been widely used in domestic mainstream powder detergent products to improve the greening of products. In addition, the powdered MES is very suitable as a main ingredient in concentrated powder detergents, which solves the problem that traditional concentrated formulas are difficult to dry and form. When MES is used in concentrated liquid detergent, it can be compounded with polyol, oleic acid and other raw materials to solve the problem of low temperature stability of the formula. MES is also widely used in various industrial fields such as pesticides, mineral processing, leather, and paint. Such as polymeric emulsifiers such as pesticide emulsifier, wettable powder, mineral flotation agent, leather fatliquor, paint film-forming agent, etc.
