According to the ecotoxicological data in the Safety Data Sheet of Guoli Chemical, isomeric alcohol ethoxylate E-1303 performs well in terms of environmental performance. Its biodegradability tested by OECD 301 method can achieve ≥60% BOD/COD or ≥70% DOC removal rate, meeting the classification standard of "readily biodegradable", which means this product can be effectively decomposed by microorganisms in the natural environment and will not accumulate in the ecosystem for a long time.
In terms of aquatic ecotoxicity, the half-effective concentrations of this product for fish (LC50), algae (EC50) and daphnia (EC50) are all greater than 100 mg/L, belonging to chemicals with low toxicity to aquatic organisms. Compared with many traditional surfactants (such as some linear alkylbenzene sulfonates), E-1303 has more prominent environmental friendliness. In addition, it is recommended to use incineration with tail gas treatment devices for waste disposal and strictly prohibit discharge into sewers or natural water bodies to minimize environmental impact.
From the perspective of overall environmental compliance, E-1303 meets the current international basic requirements for surfactant biodegradability (such as the EU Detergents Regulation EC 648/2004), making it suitable for industrial and civil formulation systems with increasingly stringent environmental requirements.
| Environmental Indicator | Test Data | Test Method/Standard |
|---|---|---|
| Biodegradability | Readily biodegradable (≥60% BOD/COD or ≥70% DOC removal) | OECD 301 |
| Fish Acute Toxicity (LC50) | >100 mg/L | Standard fish toxicity test |
| Algae Growth Inhibition (EC50) | >100 mg/L | Standard algae toxicity test |
| Daphnia Acute Immobilization (EC50) | >100 mg/L | Standard daphnia toxicity test |
| Acute Oral Toxicity (Rat LD50) | >2000 mg/kg (low toxicity) | Toxicology test |
| Skin Sensitization (Guinea pig) | Non-sensitizing | Skin sensitization test |
Isomeric alcohol ethoxylate E-1303 can be used as an ideal surfactant component for formulating environmentally friendly cleaning agents, textile auxiliaries, and pesticide preparations. Its readily biodegradable properties make it particularly suitable for products exported to markets with strict environmental requirements such as Europe and America, as well as for formulations used in sensitive ecological environments (e.g., lake basins, areas near coastal aquaculture).
Regarding the test report, I cannot directly provide PDF or paper documents at present. It is recommended that you contact the sales or technical support department of Guoli Chemical (please visit the official website for contact information) to apply for the product Certificate of Analysis (COA) or Safety Data Sheet (SDS), which should contain detailed test data on the above ecotoxicity and biodegradability.
