Castor Oil Polyoxyethylene Ether EL-60 (CAS No.: 61791-12-6) is a nonionic surfactant prepared by ethoxylation using natural castor oil as raw material. From the source of raw materials to terminal degradation, it exhibits green and environmentally friendly characteristics. According to the safety and environmental data in the product database, this product is not a dangerous substance or mixture, and meets environmental standards in terms of ecotoxicity and biodegradability.
In terms of biodegradability, the product has been tested according to OECD 301B standard, with a BOD/COD ratio greater than 60%, belonging to the "readily biodegradable" level, meaning it can be rapidly decomposed by microorganisms in the natural environment and will not accumulate in the ecosystem over the long term. Additionally, the acute toxicity test on fish (96h LC₅₀) result is greater than 100 mg/L, indicating low ecotoxicity and being relatively friendly to aquatic organisms.
In terms of human safety, the acute oral toxicity LD₅₀ of this product is greater than 5000 mg/kg (practically non-toxic grade), and the results of skin irritation test (OECD 404), eye irritation test (OECD 405), and skin sensitization test (OECD 406) are all negative. It combines both environmental protection and safety advantages, meeting the sustainable development requirements of modern green chemicals.
