Castor Oil Polyoxyethylene Ether EL-80 is synthesized from natural castor oil and ethylene oxide. The raw materials are derived from renewable resources, reducing the environmental burden at the source. In terms of ecotoxicology, this product has low acute toxicity to aquatic organisms—the 48-hour EC50 value for Daphnia magna is greater than 100 mg/L, classifying it as a substance with low ecological toxicity.
In terms of biodegradability, this product achieves a degradation rate of over 70% within 28 days under internationally recognized rapid biodegradation test standards such as OECD 301B, meeting the criterion for "ultimate biodegradability." This means that the product will not accumulate in the natural environment for a long time and can be gradually decomposed into harmless substances by microorganisms, aligning with the current global mainstream requirements for the environmental friendliness of surfactants.
Regarding test reports, Guoli Chemical undertakes to provide independent test reports for each batch of product, covering physical and chemical indicators, composition analysis, and quality parameters, ensuring product quality traceability. If you require specific environmental compliance test reports for this product (such as biodegradability test reports, acute toxicity test reports, RoHS/REACH compliance statements, etc.), it is recommended to directly contact our technical support department to obtain the latest batch test documents.
| Environmental Indicator | Data/Conclusion | Reference Standard/Description |
|---|---|---|
| Raw Material Source | Natural Castor Oil (Renewable Resource) | Non-petroleum-based raw material, lower carbon footprint |
| Biodegradability | 28-day degradation rate ≥ 70% | OECD 301B Rapid Biodegradation Test |
| Biodegradation Level | Ultimately Biodegradable | Conforms to OECD Chemical Classification Standard |
| Acute Aquatic Toxicity (Daphnia magna) | EC50 (48h) > 100 mg/L | Low toxicity level |
| Hazardous Chemical Classification | Non-hazardous Chemical | Can be transported under general chemical conditions |
| Test Report for Each Batch | Provided | Independent test report, quality traceable |
Given the good environmental characteristics of EL-80, this product is particularly suitable for application scenarios with high environmental requirements, such as personal care products, textiles (especially the finishing process of exported products), and "green emulsifiable concentrate" formulations in pesticide preparations. In formulation design, it can be compounded with anionic, non-ionic, and cationic surfactants, achieving synergistic effects without compromising the overall environmental compliance of the formulation.
