Castor Oil Polyoxyethylene Ether EL-10 (PEG-10 Castor Oil) is a nonionic surfactant, appearing as a light yellow to yellow transparent oily liquid, with a low HLB value and outstanding lipophilicity, especially suitable for W/O (water-in-oil) emulsion systems. Its usage method is usually: pre-dissolve or disperse in the oil phase, then mix with the water phase for emulsification. The specific operation process should be adjusted according to the formulation system of the final product.
This product has good resistance to acid, alkali, and hard water, maintaining high chemical activity under complex water quality or extreme pH conditions. In actual use, it is recommended to slowly add under stirring conditions to ensure uniform dispersion and fully exert its emulsifying and wetting properties. For systems that require heating (such as cream cosmetics, textile oils, etc.), it can be operated at 40~70°C, which is conducive to reducing product viscosity and improving mixing efficiency.
Since EL-10 is liquid at room temperature, it can be used directly without pre-dissolution. For high-viscosity formulations, it can be diluted with a small amount of mineral oil or oily components in the formulation before adding to the system. This product has good compatibility with anionic, cationic, and other nonionic surfactants and can be used in combination to achieve synergistic effects.

The following are usage guidelines and recommended addition amount ranges for typical application fields (addition amounts are mass percentages of the total formulation, specific values need to be optimized through experiments):
| Application Field | Recommended Addition Amount (wt%) | Usage Method |
|---|---|---|
| Pesticide Emulsifiable Concentrate (EC) | 5%~15% | Mix and dissolve with pesticide active ingredient and solvent; when used, add water to self-emulsify to form a stable emulsion |
| Textile Synthetic Fiber Oil Agent | 3%~8% | Used as a smoothing agent and wetting component, compounded with other oil agent components then applied for oiling |
| Cosmetics W/O Cream and Lotion | 2%~6% | Add to the oil phase and heat to 60~70°C to dissolve, then mix with preheated water phase and homogenize for emulsification |
