Castor Oil Polyoxyethylene Ether EL-60 (PEG-60 Castor Oil) appears as a light yellow paste, semi-solid at room temperature. Before use, it is recommended to preheat the product to 40-50°C to soften it or make it flowable for accurate weighing and uniform dispersion. For aqueous systems, it can be pre-dispersed into a paste or liquid form using a small amount of warm water (about 40-60°C) before adding to the main formulation and stirring evenly to ensure complete dissolution and optimal performance.
This product is a nonionic surfactant with a high HLB value, making it a typical O/W (oil-in-water) emulsifier, exhibiting excellent emulsifying capability for mineral oils, animal and vegetable oils, and waxes. In practical formulation design, it can be used alone or combined with other low HLB emulsifiers according to HLB matching principles to cover a wider range of oil phases and achieve better emulsion stability.
Due to its excellent chemical stability, it can be used normally in acid, alkali, and hard water systems, and can be well compounded with nonionic, anionic, cationic, and amphoteric surfactants. Therefore, the formulation has high flexibility and adaptability. The specific dosage and compounding ratio need to be optimized and confirmed through small-scale experiments based on the oil phase type, required viscosity, transparency, and stability requirements of the target system.

The following are general recommended dosage ranges for various application fields (Please note: The product database does not currently include precise dosage data; the following are industry experience reference values, and actual dosage should be verified through experiments):
| Application Field | Recommended Dosage (Reference) | Key Usage Points |
|---|---|---|
| Industrial Emulsifier (Emulsion polymerization, Industrial cleaners) | 2%-8% | Premix with oil phase and add to water phase, or directly add to system with stirring for emulsification |
| Textile Dyeing and Printing (Leveling agent, Dispersant) | 1%-5% (based on working solution) | Add directly to the dye bath, heat to process temperature before use |
| Pesticide Formulations (Emulsifiable concentrate, Emulsion in water, Microemulsion) | 3%-10% | Premix with pesticide technical material and solvents, then emulsify with water phase |
| Metalworking Fluids (Cutting fluids, Grinding fluids) | 2%-8% | Premix with base oil, rust inhibitors, etc., then dilute with water to working solution |
| Daily Chemical Products (Solubilizer, Emulsifier) | 0.5%-5% | For solubilizing fragrance oils, it is recommended to premix EL-60 with fragrance in a ratio of 1:1 to 3:1 |
| Emulsion Polymerization (Acrylate, Styrene-acrylic systems) | 1%-3% (based on total monomer weight) | Can be used alone or compounded with anionic emulsifiers, added in pre-emulsification or at the bottom of the reactor |
