OP-10 (octylphenol polyoxyethylene ether) belongs to the class of alkylphenol polyoxyethylene ethers (APEOs), which are nonionic surfactants. The core environmental controversy of these substances is that their degradation intermediates in the environment—octylphenol (OP) and short-chain polyoxyethylene ether metabolites—are recognized as environmental endocrine disruptors (EDCs) with estrogenic effects. They can persist in water bodies, accumulate through the food chain, and cause long-term harm to the reproductive functions of fish, aquatic invertebrates, and even entire ecosystems.
According to the Safety Data Sheet in the Guoli Chemical product database, the aquatic ecotoxicity data for OP-10 are: fish 96h-LC50 approximately 3–10 mg/L, daphnia 48h-EC50 less than 10 mg/L. According to the GHS classification criteria, it is clearly classified as Aquatic Chronic Category 3 (H412) — "harmful to aquatic life with long-lasting effects." This classification means that even with diluted discharge, its cumulative effects cannot be ignored.
Currently, the EU REACH regulation has listed octylphenol (4-tert-octylphenol) in the Candidate List of Substances of Very High Concern (SVHC) and imposes strict restrictions on its content in articles; EU Regulation 2016/26 further restricts residues of NPEO and OPEO in textile products. Domestically, although not completely banned, standards such as GB/T 35613-2017 "Green Product Assessment - Textile Products" have explicitly restricted the use of APEOs. Export-oriented companies need to pay special attention to compliance risks. Therefore, OP-10 is not recommended for use in end-product formulations that require environmental certification or are intended for export to European and American markets.
Whether a test report for OP-10 can be provided, there is no specific information on third-party environmental test reports for this product in this database. Whether the company can provide test reports from authoritative institutions such as SGS, Intertek for RoHS, REACH, APEO residues, as well as the product's COA (Certificate of Analysis), needs to be confirmed directly with Guoli Chemical's sales or technical support department. Typically, testing can be arranged according to customer needs. Test items generally include: APEO content, heavy metals, halogens, phthalates, and other restricted substances.
