CAS No. 406-78-0 is a chemical compound, commonly referred to as poly(epichlorohydrin) (PEC) or polyoxyethylene glycol. This compound is produced by reacting epichlorohydrin with ethylene oxide in the presence of an alkali catalyst.
PEC is a colorless, viscous liquid with a molecular weight of 270 to 270,000 and a chlorine content of 1.5 to 4%. It is soluble in water and has a low volatility. PEC is a non-ionic surfactant and is used in various industrial and consumer applications.
In the textile industry, PEC is used as a textile dyeing assistant and a dye-fixing agent. It is also used in the production of synthetic fabrics and in the finishing of leather goods. In the paper industry, PEC is used as a paper sizing agent, as well as a wetting agent and lubricant.
In the food industry, PEC is used as an emulsifier and stabilizer in food products such as margarines, shortenings, mayonnaise, and salad dressings. It is also used as a dispersing agent for food colorants and flavorings. In the cosmetics industry, PEC is used in the manufacture of lotions, creams, and shampoos.
In the pharmaceutical industry, PEC is used as a surfactant and wetting agent in the formulation of tablets, capsules, and suppositories. It is also used to improve the solubility and dissolution of active ingredients.
PEC is also used in the manufacture of paints, inks, and adhesives. In the agricultural industry, PEC is used as a dispersant, emulsifier, and wetting agent in the production of herbicides and insecticides.
Due to its low volatility and wide range of industrial applications, PEC is a very useful and versatile chemical compound. Its chlorine content is low, making it suitable for use in food and pharmaceutical applications. As a viscous liquid, it is also easy to handle and use.
