AEO-2 is a non-ionic surfactant in the fatty alcohol polyoxyethylene ether series, formed by the condensation of fatty alcohols with ethylene oxide. Here is a detailed introduction about it: Basic Information Chemical composition: It is generally prepared by the addition reaction of C₁₂-C₁₄straight chain fatty alcohols with two ethylene oxide molecules. The chemical formula is RO-(CH₂CH₂O)₂-H, where R is the C₁₂-C₁₄fatty hydrocarbon group. Appearance: Colorless and transparent liquid at 25 ℃. HLB value: about 5-6, with strong lipophilicity, belonging to water in oil emulsifier. Other indicators: Hazen ≤ 20, hydroxyl value 180-190mg KOH/g, moisture ≤ 1.0%, pH value (1% aqueous solution) 5.0-7.0. Performance Characteristics Emulsification: It has good emulsifying ability, which can make oil droplets evenly dispersed in the water phase to form a stable lotion, and is commonly used to prepare water in oil lotion. Wettability: It has a certain wetting effect on solid surfaces, which can reduce the interfacial tension between liquids and solid surfaces, allowing liquids to better spread on solid surfaces. Solubility: Poor solubility in water, but easily soluble in organic solvents such as ethanol and ether. Chemical stability: It has good stability against acids, bases, and hard water, and can maintain stable performance within a wide pH range. main purpose In the field of daily chemical industry, it can be used as an emulsifier and dispersant in products such as makeup remover oil and shower oil, helping to evenly disperse oils and improve the cleaning effect and user experience of products. Textile printing and dyeing industry: used as emulsifier and dispersant, it helps to evenly disperse and penetrate dyes and auxiliaries, improve dyeing effect and printing clarity. Metal processing industry: It can be used as a low-temperature coupling agent and coupling agent in emulsion, semi synthetic and other metal processing liquid systems to improve lubrication and cooling effects during metal processing. Coatings and Ink Industry: As a wetting agent and dispersant, it promotes the uniform dispersion of pigments and fillers, improves the leveling and adhesion of coatings and inks. Packaging and storage: Usually packaged in 190kg iron drums or 50kg plastic drums. The product is non-toxic and non flammable. It should be stored and transported in a dry and ventilated place according to general chemical storage and transportation.
