The specific addition amount of Isomeric Tridecanol Polyether E-1310 should be determined through experiments based on the application process. There is no universal fixed value in the database. Typically, when used as a core emulsifier or wetting agent, the formula proportion ranges from 1% to 10%.
Detailed Description
Isomeric Tridecanol Polyether E-1310 is a high-performance nonionic surfactant with very flexible usage methods. Before use, ensure the product is stored in the recommended environment (5°C ~ 40°C) and kept sealed. Since the product may thicken or solidify at low temperatures, if this occurs, it is recommended to thaw the packaging at room temperature before use and stir gently to mix evenly. Never use an open flame or direct steam heating.
During compounding, E-1310 can be added directly to the water phase or to the oil phase under stirring, depending on your specific emulsification process. Thanks to its excellent chemical stability and formulation compatibility, it can be freely combined with anionic, cationic, and other nonionic surfactants to produce synergistic effects. For emulsion polymerization processes, it is typically added before the polymerization reaction as a stabilizer for pre-emulsified monomer droplets.

Application Recommendations
Based on application characteristics in different fields, the recommended addition amounts are as follows:
- Industrial and Household Cleaning: As a core component in hard surface cleaners or metal degreasers, the recommended addition amount is 2% to 8% of the total formulation. In cleaning scenarios involving strong mechanical forces such as ultrasonic cleaning or high-pressure spraying, due to its low-foaming properties, the dosage can be appropriately increased to enhance degreasing power without causing foam overflow.
- Textile Printing and Dyeing Auxiliaries: In scouring agent and penetrant formulations, the recommended addition amount is typically 0.5 to 3 g/L of the working solution. It can efficiently penetrate fibers, remove cotton wax and sizing, while ensuring uniform chemical contact, improving whiteness and dye uptake.
- Pesticide Formulations: In emulsifiable concentrates (EC) or emulsion in water (EW), as the main emulsifier, the recommended addition amount is 5% to 10% of the total formulation. It ensures the stability of the emulsion when the solution is diluted, and optimizes the wetting, spreading, and adhesion of the liquid on plant leaves.
- Emulsion Polymerization: In emulsion polymerization of monomers such as acrylic acid and vinyl acetate, as an emulsifying stabilizer, the recommended addition amount is 1% to 3% of the total monomer mass. It effectively controls particle size, improving the mechanical stability and freeze-thaw stability of the final polymer emulsion.
Precautions
- Safety Protection: This product causes skin and serious eye irritation (GHS07). During opening, pouring, or stirring, must wear impermeable gloves (such as nitrile rubber) and sealed goggles to avoid direct contact.
- Environmental Control: The product is harmful to aquatic life with long-lasting effects. Do not discharge the pure product or high-concentration waste liquid directly into sewers, surface water, or soil. All cleaning waste and containers should be disposed of as hazardous waste according to local regulations.
- Storage Restrictions: Do not use aluminum or uncoated carbon steel containers for long-term storage. Use stainless steel, polyethylene, or polypropylene containers.
