C13 alcohol ethoxylate E-1340 (Isotridecyl alcohol polyoxyethylene (13) ether, CAS No. 9043-30-5) exhibits dual aspects in environmental compliance. From a degradability perspective, this product shows good environmental potential: according to Section 7 of the product SDS (Ecological Information), its ready biodegradability is greater than 60% (BOD\/COD, 28 days), classifying it as an easily biodegradable substance. This means it can be effectively decomposed by microorganisms in wastewater treatment systems and will not persist in the environment for long periods. Additionally, this product has low bioaccumulation potential, with no significant tendency for biomagnification through the food chain.
However, special attention should be paid to the fact that this product is classified under GHS as Aquatic Chronic Category 3 (H412): harmful to aquatic life with long-lasting effects. Specifically, the fish 96-hour LC50 is 1–10 mg\/L, the daphnia 48-hour EC50 is 1–10 mg\/L, and the algae 72-hour EC50 is 1–10 mg\/L, indicating acute hazards to aquatic ecosystems at higher concentrations. Therefore, during production and use, strict measures must be taken to prevent untreated wastewater from being directly discharged into natural water bodies. Treatment through standardized wastewater treatment facilities to achieve degradation and compliance discharge is essential.
Current environmental regulations for surfactants in various countries primarily focus on biodegradability as a core indicator. According to the EU REACH regulation and China's GB\/T 15818-2018 Test Method for Biodegradability of Surfactants, primary biodegradability ≥80% or ultimate biodegradability ≥60% (28 days) is generally considered the threshold for compliance. The biodegradability of C13 alcohol ethoxylate E-1340 is greater than 60%, meeting the basic requirements of relevant regulations. However, whether it specifically meets certification standards for end-use applications (such as Eco-label, EU Ecolabel, etc.) requires further evaluation based on complete ecotoxicological assessment reports and the overall formulation of the end product.
| Parameter | Test Value | Description |
|---|---|---|
| Ready Biodegradability (28-day BOD\/COD) | >60% | Easily biodegradable substance |
| Acute Fish Toxicity (96h LC50) | 1–10 mg\/L | Harmful to aquatic life |
| Acute Daphnia Toxicity (48h EC50) | 1–10 mg\/L | Harmful to aquatic life |
| Acute Algae Toxicity (72h EC50) | 1–10 mg\/L | Harmful to aquatic life |
| Bioaccumulation Potential | Not significant | Low bioaccumulation risk |
| GHS Aquatic Toxicity Classification | Aquatic Chronic Category 3, H412 | Harmful to aquatic life with long-lasting effects |
In application scenarios with high usage volumes such as textile dyeing and printing, industrial cleaning, and leather processing, it is recommended that enterprises incorporate the use of C13 alcohol ethoxylate E-1340 into their overall environmental management system. Industrial wastewater should be treated using activated sludge or biofilm biochemical treatment processes before discharge. After treatment, the wastewater should be regularly monitored for COD and toxicity indicators to ensure compliance with local environmental discharge standards. In end-use applications such as pesticide formulations and water-based coatings, the dosage should be rationally controlled during formulation design to balance performance and environmental requirements.
The Guoli Chemical product database currently does not include batch test reports (COA) or third-party environmental test reports for C13 alcohol ethoxylate E-1340. To obtain specific test reports for this product (such as biodegradability test reports, heavy metal test reports, VOC test reports, etc.), it is recommended that you directly contact the sales or technical support team of Guoli Chemical, providing the list of required test items and purchasing needs. The relevant department will provide the corresponding quality inspection report based on the product batch. Typically, Guoli Chemical issues a COA for each batch, covering routine indicators such as appearance, hydroxyl value, moisture content, pH value, etc. For special environmental tests (such as OECD 301B biodegradation tests, etc.), third-party testing can be arranged based on customer requirements.
