Emulsifier SG-100 (PEG-100 Stearate) performs well in terms of environmental compliance and is an environmentally friendly nonionic surfactant. According to the ecotoxicological data tested by authoritative institutions in Guoli Chemical's product database, this product meets internationally recognized environmental standards in terms of biodegradability, ecotoxicity, heavy metal limits, etc., meeting the selection requirements of downstream customers for green chemicals.
In terms of biodegradability, this product has been tested by the OECD 301 method, with a degradation rate greater than 60% in 28 days, belonging to the "readily biodegradable" level. After being discharged into the environment, it can be quickly decomposed by microorganisms and will not accumulate in the ecosystem for a long time. Ecotoxicity tests show that the 96-hour LC₅₀ for fish is greater than 100 mg/L, belonging to the low ecotoxicity level, causing minimal harm to aquatic organisms. In addition, the heavy metal content of the product is strictly controlled at ≤20 mg/kg, and the arsenic content is ≤2 mg/kg, far below the conventional access limits for daily chemicals and industrial products.
Regarding test reports, Guoli Chemical issues a Certificate of Analysis (COA) for each batch of emulsifier SG-100, covering appearance, pH value, active content, acid value, saponification value, moisture, heavy metals, and other conventional indicators. If a third-party special environmental test report is required for specific end applications (such as cosmetic registration, REACH compliance, export customs clearance, etc.), or a complete ecotoxicological report including OECD 301 biodegradability, fish acute toxicity, and other items, please contact the sales department of Guoli Chemical. We will coordinate the issuance or entrust a third-party testing institution with CNAS/CMA qualification to provide it according to your needs.

Based on the excellent environmental and safety characteristics of emulsifier SG-100, it is particularly suitable for the following fields with strict environmental requirements:
Although this product has excellent environmental indicators, the following points still need attention during normal use: Waste must not be directly discharged into sewers or natural water bodies; high-temperature incineration with tail gas purification devices is recommended for disposal; the ester bond of the product may hydrolyze in strong acid (pH<3) or strong alkali (pH>8) environments, affecting the use effect and producing free fatty acids and polyethylene glycol; avoid long-term use or storage under such extreme conditions. If batch COA or special environmental test reports are required, please contact the sales department of Guoli Chemical in advance, specifying the specific purpose and required test items, so that we can arrange them in a timely manner.
