A nonionic surfactant is a surfactant that does not generate ions in an aqueous solution. It is different from Anionic Surfactant and Cationic Surfactant. A nonionic surfactant is a surfactant that does not generate ions in an aqueous solution. Its solubility in water is due to its strong affinity for water.
Compared with anionic types, nonionic surfactants have higher emulsifying ability and have certain hard water resistance. They are indispensable ingredients in detergent and emulsifier formulations. Of course, compared with anionic surfactants, non-ionic surfactants also have some disadvantages, such as cloud point limitation, alkali resistance, and higher prices.
Nonionic Surfactant is mostly liquid and slurry. Its solubility in water decreases with increasing temperature. Non-ionic surfactants have many properties such as good washing, dispersing, emulsifying, wetting, solubilizing, leveling, anti-corrosion, and protective colloid. They are widely used in textile, paper, food, plastic, leather, fur, Glass, petroleum, chemical fiber, medicine, pesticide, coating, dye, fertilizer, film, photography, metal processing, beneficiation, building materials, environmental protection, cosmetics, fire protection and agriculture.
1. Polyoxyethylene ether of alkylphenol
TX / NP is suitable for use under low temperature conditions, with more comprehensive performance, and is mostly used in the field of cleaning. Although alkylphenol polyoxyethylene ether is not environmentally friendly, its emulsification and cleaning effect is still quite outstanding. It still plays a huge role in areas such as agriculture and industrial hard surface cleaning that do not require APEO.
2. Fatty alcohol polyoxyethylene ether
3. Fatty acid methyl ester polyoxyethylene ether FMEE
FMEE is a polyoxyethylene ether based on methyl stearate. It is a petroleum derivative and does not belong to the category of green surfactants. However, this type of FMEE has excellent cleaning ability, its emulsification performance is second only to the isomeric alcohol ether and alkyl phenol polyether series, but it is better than the linear AEO series and secondary alcohol S series, and has excellent dispersion. Performance, high cloud point, low foam characteristics.
FMEE has been widely used in foreign markets, especially in the field of industrial cleaning. Compared with other alcohol ether products, a significant feature of FMEE is that it has a balanced performance.
Detergent 6501 series is also a widely used non-ionic surfactant. The main feature is that it has the function of thickening and foam stabilization. The 6501 series has poor cleaning and degreasing capabilities, which is far inferior to AEO series. Generally 6501 is mostly used for detergents and low-grade daily necessities.
6501 is divided into three models, namely 1: 1, 1: 1.5, and 1: 2. The thickening performance becomes worse in turn, and the cleaning and emulsifying properties are enhanced in turn. 6501 has poor emulsification and cleansing ability. It cannot be used as the main raw material in the formula, and can only be used as an auxiliary component, which can reduce costs, improve appearance, and increase foam.
The above is the non-ionic surfactant related information introduced by Nonionic Surfactant Supplier.
