Castor Oil Polyoxyethylene Ether EL-10 (CAS: 61791-12-6) is a nonionic surfactant produced by the addition polymerization of ethylene oxide with natural castor oil as the starting material. From the perspective of raw material source, castor oil is a renewable natural plant oil. Compared with petroleum-based surfactants (such as alkylphenol ethoxylates APEO products), its bio-based origin gives the product better environmental affinity. In terms of toxicity data, the product database clearly marks it as a low-toxicity substance, with low inhalation or ingestion toxicity. It does not fall under the acute toxicity category of hazardous chemical classification, and its flash point is >150°C, making it a non-flammable liquid with low fire risk during storage, transportation, and use.
In terms of environmental fate, as a polyoxyethylene-type nonionic surfactant, the molecular structure of PEG-10 castor oil contains ester bonds and ether bonds, theoretically giving it a certain potential for biodegradation. However, it should be noted that the actual degradation rate is influenced by factors such as the number of ethylene oxide adducts (10 EO for this product) and environmental conditions (temperature, microbial community). It needs to be quantitatively assessed through standard biodegradability tests (such as the OECD 301 series). Additionally, this product is a low-foaming surfactant, which can reduce the impact of foam discharge on water bodies in applications such as industrial cleaning.
Currently, the product database does not include specific environmental certification information for this product (such as REACH compliance statements, RoHS tests, biodegradability test reports, etc.), nor are there direct records matching "EL-10 environmental test report". Therefore, regarding compliance with specific national or industry environmental regulations, it is recommended to directly contact the technical support department of Guoli Chemical for confirmation based on your specific application scenario and compliance requirements.
| Parameter Item | Value/Description | Environmental Relevance Explanation |
|---|---|---|
| Hazard Classification | Non-hazardous, non-flammable liquid | Not within the scope of hazardous chemical control, low threshold for transportation and storage |
| Toxicity Grade | Low toxicity | Low acute toxicity risk, minimal potential harm to operators and aquatic organisms |
| Flash Point | >150°C | High flash point, non-flammable, reduces VOC and fire environmental risks |
| Heavy Metal Content | ≤10 ppm | Meets general industrial product heavy metal limit requirements |
| Arsenic Content | ≤2 ppm | Very low arsenic residue, meets strict standards for cosmetics and other industries |
| pH Value (1% Aqueous Solution) | 5.0—7.0 | Nearly neutral, minimal impact on water and soil pH |
| Foaming Characteristics | Low foam | Reduces foam load in wastewater treatment, lowers the need for defoamers |
| Raw Material Source | Natural castor oil | Renewable resource, reduces reliance on petroleum-based raw materials |
| Biodegradability/REACH Reports, etc. | Not available for this parameter | Need to separately request specialized test reports from the supplier |
This product has been widely used in cosmetics, pesticide formulations, textile auxiliaries, and other fields, indirectly indicating that its safety for humans and the environment under normal use conditions has been recognized by the industry. If you plan to use it for export to the EU market or for end products with strict environmental audit requirements (such as ECO-labelled cleaners, organic cosmetics, etc.), it is recommended to contact Guoli Chemical regarding the following dimensions:
