Castor Oil Polyoxyethylene Ether EL-80 has good environmental performance. It is a non-ionic surfactant that is ultimately biodegradable, and Guoli Chemical can provide independent test reports for each batch of product.

Detailed Description

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.

Application Recommendations

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.

Precautions

  • Although EL-80 has excellent biodegradability and low toxicity, it is strictly prohibited to discharge directly into water bodies, soil, or drainage systems without treatment. Wastewater after use should be discharged after conventional industrial wastewater treatment in accordance with local regulations.
  • Disposal of waste should comply with local, regional, and national regulations. It can be incinerated in licensed waste treatment facilities or handed over to qualified waste treatment agencies for disposal.
  • If it is to be used in end products with specific environmental certifications (such as EU Ecolabel, Nordic Swan, Blue Angel, etc.), it is recommended to submit special test data to the certification body in advance and obtain confirmation.
  • Test reports (including Safety Data Sheets) are batch-specific documents. Please contact Guoli Chemical's technical support with your purchase batch number to obtain the corresponding version.
