C9-11 Pareth-6 là gì? Ứng dụng, liều dùng, sản phẩm thay thế & thông số

C9–11 Pareth-6, chemically known as C9–11 Fatty Alcohol Ethoxylate (6 EO), has the CAS number 68439–46–3. It is a nonionic surfactant belonging to the fatty alcohol ethoxylate family, produced by the ethoxylation of C9-C11 synthetic fatty alcohols with an average of 6 moles of ethylene oxide (EO). Its INCI name is C9–11 PARETH-6, and it is listed as No. 00227 in China's "Catalog of Used Cosmetic Ingredients". The molecular structure of C9–11 Pareth-6 consists of a C9-C11 alkyl hydrophobic chain and a polyoxyethylene hydrophilic chain composed of approximately 6 ethylene oxide units, forming a typical amphiphilic molecular structure. The product appears as a colorless transparent liquid to white paste (liquid when EO number is below 9), with a slight characteristic odor. It exhibits good water solubility and excellent wetting, penetrating, detergency, emulsifying, dispersing, and solubilizing properties. As a nonionic surfactant, C9–11 Pareth-6 features low foaming, biodegradability, and APEO-free (free of alkylphenol ethoxylates) environmental characteristics. Its HLB value is approximately 12.4–12.5, making it suitable for O/W (oil-in-water) emulsification systems. It is widely used in personal care products, household detergents, industrial cleaning, textiles, leather, synthetic fibers, pesticides, and petrochemical applications.

C9–11 Pareth is a series of nonionic surfactants produced by the addition reaction of C9–11 alcohols with varying molar numbers of ethylene oxide. As the EO addition number varies, the HLB value, physical state, and application properties of the products also change accordingly: Variety
