Isotridecanol Polyether E-1310 is a high-performance nonionic surfactant starting from isotridecanol with 10 moles of ethylene oxide chains. Its core uses cover industrial and household cleaning, textile printing and dyeing, leather processing, pesticide formulations, and emulsion polymerization, functioning as an efficient emulsifier, wetting and penetrating agent, and dispersant.
Detailed Description
Isotridecanol Polyether E-1310 (CAS: 9043-30-5) is a low-foaming nonionic surfactant. Its molecular structure consists of a hydrophobic group of branched isotridecanol combined with a hydrophilic chain of approximately 10 ethylene oxide units. This unique "isomerized" branched structure endows it with comprehensive performance superior to conventional linear alcohol polyethers, especially outstanding in low-temperature fluidity, chemical stability, and surface activity efficiency.
As one of the core products of Guoli Chemical, E-1310 exhibits excellent wetting, penetrating, emulsifying, and dispersing capabilities, maintaining stability and activity over a wide pH range, hard water conditions, and electrolyte systems. Its low-foaming and easy-rinsing properties make it highly valuable in modern industrial formulations pursuing high efficiency, energy saving, and emission reduction. Additionally, it has excellent formulation compatibility, synergizing with anionic, cationic, and other nonionic surfactants, providing formulators with high design flexibility.
Main Uses
Based on its comprehensive and balanced performance, Isotridecanol Polyether E-1310 plays a multifunctional core auxiliary role in several key industrial sectors:
- Industrial and Household Cleaners: As an effective component in hard surface cleaners and metal degreasers, it quickly spreads and penetrates dirt, providing strong oil removal capability, and rinses thoroughly even in cold water without leaving residues.
- Textile Printing and Dyeing Auxiliaries: Used as a scouring agent and penetrant in pretreatment processes, it efficiently penetrates fibers to remove cotton wax, sizes, and other impurities, ensuring uniformity and high whiteness in subsequent bleaching and dyeing processes.
- Leather Processing: Applied in pretreatment stages such as soaking, degreasing, and bating of raw hides, it accelerates chemical penetration, uniformly removes natural fats, improves leather softness and fullness, and ensures a fine and smooth grain.
- Pesticide Formulations: As an emulsifier for water-based formulations (e.g., emulsifiable concentrates, oil-in-water emulsions), it instantly disperses oily active ingredients into stable emulsions, significantly improving dilution stability and wetting/spreading on crop surfaces, thereby enhancing efficacy.
- Emulsion Polymerization: Serves as an emulsifier and stabilizer during the polymerization of synthetic emulsions like acrylates and vinyl acetate, helping to produce high-quality latex with uniform particle size distribution, excellent mechanical stability, and freeze-thaw stability.

Application Recommendations
In practical formulations, the recommended dosage of Isotridecanol Polyether E-1310 should be adjusted based on the specific application and formulation system, typically ranging from 2% to 15% of the total formulation. In leather degreasing or textile scouring agents, a small amount of anionic surfactant can be compounded to achieve synergistic effects and improve detergency. In emulsion polymerization, the recommended dosage is 1% to 3% of the total monomer weight to ensure latex stability.
Precautions
- Irritation Protection: This product is classified under GHS as causing skin irritation (H315) and eye irritation (H319). Chemical-resistant gloves and protective goggles must be worn during handling.
