According to the technical data from Guoli Chemical, Castor Oil Polyoxyethylene Ether EL-80 possesses six core advantages over similar nonionic surfactants: outstanding emulsification and solubilization ability, excellent wetting and penetration properties, tolerance to hard water and acid/alkali stability, low foaming characteristics, antistatic and smoothing properties, and superior compounding compatibility.
This product is synthesized by condensing natural castor oil with approximately 80 moles of ethylene oxide (EO), with an HLB value as high as 15.5~16.5, making it a highly hydrophilic nonionic surfactant. This unique structural foundation gives it more comprehensive performance compared to conventional nonionic surfactants such as fatty alcohol polyoxyethylene ether (AEO series) and alkylphenol polyoxyethylene ether (TX/NP series).
Below is a detailed comparison of the advantages of EL-80 over conventional similar products:
### 1. Low Foaming Properties, Improving Process Efficiency
Unlike conventional nonionic surfactants, which tend to generate a large amount of foam during use and require additional defoamers, EL-80 produces very low foam at working temperatures and is easy to rinse. This is a significant advantage in industrial cleaning and metalworking fluid applications, significantly reducing defoamer usage, simplifying formulations, and lowering costs.
### 2. Antistatic and Smoothing Properties
The natural fatty acid ester chain and long-chain polyoxyethylene ether in the EL-80 molecule work synergistically, imparting unique antistatic and fiber smoothing/softening effects. This is a property not found in conventional nonionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). This allows EL-80 to function simultaneously as a smoothing agent and antistatic agent in synthetic fiber spinning oils, effectively reducing the dynamic friction coefficient of fibers and minimizing fluff and breakage.
### 3. Excellent Compounding Compatibility
EL-80 can be compounded with various ionic surfactants (anionic, cationic, nonionic) and most organic solvents and additives, providing synergistic effects and strong formulation adaptability. This ensures that in complex application systems (such as pesticide emulsifiable concentrates and textile auxiliaries), it does not cause precipitation, delamination, or failure due to ionic conflicts.
### 4. Tolerance to Hard Water and Electrolyte Stability
In many industrial scenarios, water hardness is high or the formulation contains a large amount of electrolytes. EL-80 maintains good activity and stable and reliable performance in hard water, weak acid, and weak alkaline media. In contrast, some anionic surfactants (such as dodecylbenzene sulfonate) tend to form calcium soap precipitates in hard water, losing their effectiveness.
### 5. Natural Source and Environmental Friendliness
EL-80 is derived from natural castor oil and is a renewable resource-based surfactant. It has good biodegradability, with a degradation rate of over 70% in 28 days in quick biodegradability tests, aligning with the trend of green chemical development. This is an advantage that some petroleum-based similar products (such as NP/TX series, which are restricted due to environmental hormone issues) cannot match.
Summary: Castor Oil Polyoxyethylene Ether EL-80 is a versatile nonionic surfactant that combines efficient emulsification, low foaming, antistatic properties, and environmental friendliness.

If you need to apply this product in a specific formulation, Guoli Chemical recommends conducting a small-scale test using the following recommended dosages as a starting point:
| Application Area | Recommended Use | Recommended Dosage (% of total formulation) |
| :--- | :--- | :--- |
| Industrial Cleaning | Enhance degreasing and deoiling ability | 1% - 5% |
| Pesticide Emulsifiable Concentrate | Main emulsifier | 5% - 12% |
| Textile Spinning Oil | Smoothing agent, antistatic agent | 0.1% - 0.5% (of working solution) |
| Metalworking Fluid | Emulsification and lubrication component | 1% - 3% |
| Personal Care Products | Solubilizer for oil-soluble components | Adjust according to solubilizate characteristics |
Precautions:
- This product may appear pasty or solidify at low temperatures. Before use, preheat at 25-40°C and stir evenly; this does not affect performance.
- Keep the container sealed during storage to avoid moisture absorption. Recommended storage temperature is 5-35°C.
