According to the product safety data from Guoli Chemical, castor oil polyoxyethylene ether EL-10 (CAS number: 61791-12-6) is low-toxicity upon inhalation or ingestion and is not classified as a hazardous chemical. Its main health effects are concentrated on local irritation: it causes mild irritation to the eyes and skin, and repeated or prolonged contact may lead to skin defatting and dryness. Under normal industrial use conditions, as long as operating procedures are followed and appropriate personal protective equipment is worn, the health risk is controllable.
This product is a non-flammable liquid (flash point >150°C) and is not classified as a dangerous good. However, when decomposed at high temperatures or in flames, it releases irritating gases such as carbon monoxide and carbon dioxide, so it should be avoided for use or storage under extreme high-temperature conditions. Heavy metal content is strictly controlled, with total heavy metals ≤10 mg/kg and arsenic ≤2 mg/kg (source: Guoli Chemical product database), meeting industrial application safety standards.
Castor oil polyoxyethylene ether EL-10 is modified from natural castor oil via ethoxylation and, compared to fully synthetic petrochemical surfactants, has relatively better renewability and lower ecological burden. This product is low-foaming and does not easily cause persistent foam pollution in actual water environments.
However, as a nonionic surfactant, this product has excellent emulsifying ability. Once it enters a water body in large quantities, it may interfere with the cell membranes of aquatic organisms, affecting the normal functions of the aquatic ecosystem. It is easily soluble in organic solvents such as ethanol and ether. Strict control should be exercised during use and waste disposal, and direct discharge into sewers, surface water, or soil without treatment is strictly prohibited. Currently, the Guoli Chemical database has not provided clear biodegradability data (such as BOD/COD ratio, OECD degradation test results) and ecotoxicity data (such as LC50, EC50) for this product. It is recommended that users conduct their own environmental impact assessments or consult Guoli Chemical technical support when using and discharging large quantities.

Although castor oil polyoxyethylene ether EL-10 is widely used in cosmetics, pesticides, and other fields, when used in product formulations, its safety should be evaluated based on the intended use of the final product. If used in cosmetics or products that may come into contact with the human body, it must comply with the relevant regulations on raw material usage specifications and impurity limits. For further questions, it is recommended to directly contact the Guoli Chemical technical team to obtain a detailed safety data sheet or conduct a specific assessment.
