The environmental advantages of castor oil polyoxyethylene ether EL-12 are mainly reflected in three aspects. First, natural source of raw materials - this product uses natural castor oil as the starting raw material instead of a purely petroleum-based synthetic route, which reduces the carbon footprint of the product and dependence on non-renewable resources from the source. Second, the product has excellent biodegradability and belongs to the rapidly biodegradable surfactant category. After use, when entering the environmental water body, it can be effectively decomposed by microorganisms without causing long-term cumulative pollution. Third, the product has low toxicity to aquatic organisms, belonging to the low-toxicity level, and has a relatively small impact on the aquatic ecosystem under normal use and discharge conditions.
From a toxicological perspective, EL-12 has an acute oral toxicity LD₅₀ greater than 5000 mg/kg, which is actually non-toxic; the skin irritation test and eye irritation test results are both non-irritating, with no skin sensitization, and its safe application in the field of personal care products has been verified over the long term. These characteristics allow the product to be used safely in application scenarios that directly or indirectly contact the human body, such as cosmetics and agrochemical formulations.
It needs to be honestly stated that regarding formal third-party test reports (such as ROHS, REACH compliance reports, biodegradability test reports, SDS/MSDS documents, etc.), the database has not yet collected specific test report numbers and issuing institutions. It is recommended to directly contact the sales or technical department of Haian Guoli Chemical Co., Ltd. We can provide corresponding compliance test documents and declarations according to your specific needs (such as export region regulations, customer audit requirements, etc.).

For applications with strict environmental compliance requirements (such as exporting EU cosmetics, ECO-cert certified formulations, bio-based content certified products, etc.), EL-12 has natural advantages due to its natural origin and non-ionic characteristics. In formulation design, this product can replace some ethoxylated synthetic alcohol surfactants, helping formulators achieve the goal of developing "green formulations." It is recommended that before introducing the formula, apply for the corresponding batch certificate of analysis (COA) from Guoli Chemical and confirm the applicability of required specific regulations (such as EU REACH registration, ECOCERT/COSMOS certification).
