What is the main component of Peregal O-20?

The main component of Peregal O-20 is C16-18 fatty alcohol polyoxyethylene (20) ether, a non-ionic surfactant.

Detailed Description

Peregal O-20, chemically known as C16-18 fatty alcohol polyoxyethylene (20) ether (Polyoxyethylene (20) cetostearyl ether), is a non-ionic surfactant produced by the addition polymerization of C16-C18 natural fatty alcohols (a mixture of cetyl alcohol and stearyl alcohol) with approximately 20 moles of ethylene oxide (EO). Its CAS number is 68439-49-6.

The core component of this product is polyoxyethylene (20) cetostearyl ether, a polyoxyethylene ether derivative of cetostearyl alcohol. In its molecular structure, the hydrophobic end is a long-chain C16-C18 alkyl group (derived from natural fatty alcohols), and the hydrophilic end is a polyoxyethylene chain segment (approximately 20 EO units). This unique "amphiphilic" molecular structure imparts excellent emulsifying, wetting, penetrating, and dispersing properties to Peregal O-20.

Peregal O-20 appears as a milky white to pale yellow waxy solid or paste. It contains no organic solvents or other harmful diluents and is of high purity. As a non-ionic surfactant, its aqueous solution is neutral and unaffected by calcium or magnesium ions in water. It exhibits excellent hard-water resistance and can be widely used in combination with anionic, cationic, and amphoteric auxiliaries and surfactants.

Application Recommendations

Based on the characteristics of the C16-18 fatty alcohol polyoxyethylene ether component in Peregal O-20, its main recommended applications include:

• Textile Printing and Dyeing: Acts as an efficient leveling agent and dispersant, possessing good affinity for direct dyes and vat dyes, effectively slowing the dye uptake rate and preventing color spots and uneven dyeing.
• Pesticide Formulations: Used as an emulsifier for preparing emulsions in water (EW) and microemulsions (ME), reducing oil/water interfacial tension and forming stable O/W emulsion systems.
• Household Chemicals: Used as an O/W emulsifier and solubilizer in creams, lotions, and shampoos, imparting a fine and lustrous texture to products.
• Industrial and Household Liquid Detergents: Provides excellent detergency, emulsifying, and dispersing properties.
• Metal Processing, Papermaking, Leather: Serves as a penetrating agent and wetting agent, accelerating the penetration of treatment solutions into materials.
