The core characteristics of Isomeric Tridecanol Polyether E-1310 are: achieving a balance of "low foaming, strong wetting and penetration, and efficient emulsification and dispersion" through the isomeric hydrophobic chain structure, while possessing excellent chemical stability and formulation compatibility, making it a high-performance nonionic surfactant in multiple industrial fields.
Detailed Description
Isomeric Tridecanol Polyether E-1310 (CAS: 9043-30-5) is a nonionic surfactant synthesized by addition polymerization of isomeric tridecanol as the starting agent and ethylene oxide (approximately 10mol). The unique isomeric hydrophobic chain in its molecular structure is the basis of its performance—compared to linear alcohol ethers, the branched isomer disrupts the regular molecular arrangement, endowing the product with stronger wetting and spreading ability and lower foaming properties. The appearance of this product is a colorless to light yellow transparent liquid, with an HLB value of about 13.3, a cloud point range of 50~70°C, good hydrophilicity, and is easily soluble in water.
In terms of performance, E-1310 excels in four dimensions: emulsification, wetting, penetration, and dispersion. It has strong emulsifying power for various oil phases such as mineral oils, animal and vegetable oils, and organic solvents, while also stably dispersing solid particles in the system. Even at low temperatures or on difficult-to-wet substrate surfaces, it can spread quickly and penetrate deeply. Its foam characteristics are typically low-foaming, producing controlled low foam during application and rinsing quickly with cold water, effectively saving water and energy. Additionally, this product maintains structural stability in acid, alkali, hard water, and electrolyte systems, and can be compounded and synergized with anionic, cationic, and other nonionic surfactants, offering high flexibility in formulation design.

Application Recommendations
Based on its performance characteristics, E-1310 performs exceptionally well in the following areas:
- Industrial and Household Cleaning: As a core component in hard surface cleaners and metal degreasers, recommended dosage 2%~8% (adjust according to formulation and soil level). Low-foaming properties make it suitable for high-pressure spraying and automatic cleaning equipment, rinsing quickly with cold water without residue.
- Textile Printing and Dyeing Auxiliaries: Used as a component in wetting agents and scouring agents, it promotes uniform contact of chemicals with fibers during desizing, scouring, and bleaching processes. Recommended dosage 0.5~3g/L, effectively improving whiteness and dye uptake uniformity.
- Leather Processing: Used in soaking and degreasing processes to promote chemical penetration into the hide interior. Recommended dosage 0.3%~1.5% (based on hide weight), helping to preserve the grain surface delicacy.
- Pesticide Formulations: As an emulsifier for emulsifiable concentrates (EC) and oil-in-water emulsions (EW), recommended dosage 5%~15%, ensuring dilution emulsification stability and target wetting and spreading effects.
- Emulsion Polymerization: Used in emulsion polymerization of monomers such as acrylates and vinyl acetate, recommended dosage 1%~3% (based on total monomer weight), providing steric stabilization, resulting in latex with uniform particle size and excellent mechanical stability.
Precautions
- Safety Protection: This product is classified as GHS07 warning chemical, can cause skin irritation (H315) and serious eye irritation (H319). Must wear nitrile rubber gloves and chemical safety goggles during operation, avoid direct contact with skin and eyes.
- Environmental Control: Harmful to aquatic life with long lasting effects (H412), do not discharge directly into surface water or public drainage systems. Waste liquid and packaging containers must be disposed of according to hazardous waste regulations.
- Storage Conditions: Recommended storage temperature 5°C~40°C, keep container tightly sealed, avoid mixed storage with strong acids, strong alkalis, and oxidizers. Packaging materials should be stainless steel, polyethylene, or polypropylene, avoid using aluminum or uncoated carbon steel containers.
- First Aid Measures: For skin contact, immediately wash with plenty of soapy water for at least 15 minutes; for eye contact, immediately flush with flowing clean water for at least 15 minutes while holding eyelids open, seek medical attention if irritation persists. For more safety information, refer to the Safety Data Sheet (SDS).
