What are the main components of Isomeric Alcohol Polyether E-1303?

The main component of Isomeric Alcohol Polyether E-1303 is Isotridecanol Ethoxylate (3EO), a nonionic surfactant prepared by ethoxylation of isotridecanol with ethylene oxide.

Detailed Description

The chemical nature of Isomeric Alcohol Polyether E-1303 is a fatty alcohol polyoxyethylene ether compound. Its molecular structure consists of two parts: the hydrophobic end is a branched-chain isotridecanol (C13 isomeric alcohol), which gives the product a unique branched alkyl hydrophobic structure; the hydrophilic end is a polyoxyethylene chain segment consisting of approximately 3 ethylene oxide (EO) addition units. The "E-1303" in the product name represents this meaning — "13" refers to the C13 isomeric alcohol carbon chain, and "03" refers to an average ethoxylation degree of 3.

Thanks to the branched hydrophobic structure of isotridecanol, compared with linear alcohol ether products, E-1303 exhibits lower foaming tendency, faster wetting and spreading speed, and superior penetration performance. Its CAS number is 9043-30-5. It is a typical nonionic surfactant that maintains stable interfacial activity in a wide range of acidic, alkaline, and hard water environments, and is compatible with anionic, cationic, and other nonionic surfactants.

Application Suggestions

By virtue of its low EO number structural characteristics, the hydrophilic-lipophilic balance of Isomeric Alcohol Polyether E-1303 leans towards the lipophilic end, thus emulsifying ability and penetrating power are outstanding, especially suitable for the following scenarios:

• Industrial Cleaning Field: As a core surfactant to formulate low-foaming water-based metal cleaners and hard surface cleaners, effectively removing heavy oil stains.
• Textile Printing and Dyeing Auxiliaries: Used as high-efficiency scouring agent and penetrant, promoting rapid penetration of working fluid into fibers.
• Leather Processing: In degreasing process, it exhibits excellent emulsifying and penetrating effects, accelerating the emulsification and removal of natural oils.
• Pesticide Formulations: As an emulsifier for emulsifiable concentrates, emulsion concentrates, etc., enhancing the wetting and spreading ability of the liquid on plant leaves.
• Emulsion Polymerization: As a nonionic emulsifier participating in emulsion polymerization of vinyl acetate, acrylates, etc., ensuring smooth polymerization reaction.
