Isotridecanol Polyoxyethylene Ether E-1310 is a low-foam nonionic surfactant formed by the addition polymerization of isotridecyl alcohol with 10 moles of ethylene oxide, combining excellent wetting, penetration, emulsification, dispersion, and easy rinsing properties.
Detailed Description
Isotridecanol Polyoxyethylene Ether E-1310 (CAS: 9043-30-5) belongs to the fatty alcohol polyoxyethylene ether class of nonionic surfactants, with the full chemical name Isotridecanol Polyoxyethylene (10) Ether, and the corresponding English name Isotrideceth-10. Its molecular structure features a hydrophobic end using isotridecyl alcohol, which differs from linear alcohol structures, imparting a lower pour point and better low-temperature fluidity, as well as faster spreading ability on complex substrate surfaces.
The core performance advantages of this product lie in the balance between "low foam and easy rinsing" and "strong penetration"—in industrial cleaning scenarios, it efficiently removes oil stains without producing large amounts of hard-to-eliminate foam, and can be thoroughly rinsed with cold water; in textile pretreatment, it penetrates fiber gaps to remove cotton wax and sizing agents. Its HLB value is approximately 13.3, with a cloud point range of 50~70°C, providing a balanced hydrophilic-lipophilic profile suitable for a wide range of applications.
As one of the core products of Guoli Chemical, E-1310 remains structurally stable in acid, alkali, hard water, and electrolyte systems, and can be freely formulated with anionic, cationic, and other nonionic surfactants, offering formulation engineers highly flexible compounding options.

Application Recommendations
- Industrial and Household Cleaning: Used as a core surfactant component in hard surface cleaners and metal degreasers, recommended dosage 5%~15%, leveraging its low foam and strong detergency to quickly remove oil and dirt, rinsing clean with cold water without residue.
- Textile Dyeing and Printing Auxiliaries: Used as a wetting agent and scouring agent in desizing, scouring, bleaching, and dyeing processes, recommended dosage 2~8 g/L, helping chemicals uniformly contact fibers, improving whiteness and dyeing uniformity.
- Leather Processing: Applied in pretreatment processes such as soaking, degreasing, and bating, recommended dosage 0.5%~3% (based on leather weight), promoting chemical penetration and protecting the grain surface.
- Pesticide Formulations: Used as an emulsifier in emulsifiable concentrates (EC), emulsions in water (EW), and microemulsions (ME), recommended dosage 3%~10%, ensuring dilution stability of the formulation, optimizing spray wetting and target spreading.
- Emulsion Polymerization: Used as an emulsifying stabilizer monomer in the synthesis of emulsions such as vinyl acetate and acrylates, recommended dosage 1%~4% (based on monomer weight), ensuring fine and uniform latex particles and good mechanical and freeze-thaw stability of the latex.
Precautions
- This product is classified under GHS as skin irritant (Category 2) and serious eye irritant (Category 2). Wear impervious gloves and tight-seal goggles during handling, avoiding direct skin and eye contact.
- Harmful to aquatic life with long-lasting effects (H412). Do not discharge directly into surface waters or public drainage systems. Waste liquid and containers must be disposed of as hazardous waste in accordance with local regulations.
- Recommended storage temperature 5°C~40°C, avoid extreme high or low temperatures, keep containers sealed; prolonged low-temperature storage may cause solidification or thickening, warm up before use to restore fluidity.
- Container materials should be stainless steel, polyethylene, or polypropylene; avoid aluminum or uncoated carbon steel containers.
- Non-flammable liquid (flash point >150°C), but combustion or high-temperature decomposition may produce carbon monoxide, carbon dioxide, and irritating aldehydes and ketones; firefighting water must be collected and treated, do not discharge into rainwater drains.
- Compatible with anionic, cationic, and other nonionic surfactants for compounding, offering high formulation design flexibility.
