Thickeners 6000DS, thickener 638, and PEG-150 are essentially PEG-150 distearate (CAS: 9005-08-07), belonging to nonionic surfactants/thickeners. According to the safety data sheet in Guoli Chemical's product database, this series of products is non-toxic, non-flammable, and will not cause significant harm to the environment when stored and used under recommended conditions. The products themselves do not contain heavy metals (heavy metal content ≤20 mg/kg, arsenic ≤2 mg/kg), and key indicators such as acid value and iodine value are at low levels, indicating stable chemical properties and controlled impurity content, meeting the basic environmental requirements for general industrial chemicals.
In terms of biodegradability, the molecular structure of PEG-150 distearate contains polyethylene glycol long chains and fatty acid ester bonds, judging from the chemical structure, it has a certain degree of potential for biodegradability, but the database does not currently provide clear biodegradability rate data (such as OECD 301B test results). At the application level, this product is widely used in personal care products (shampoo, shower gel, cream lotion) and construction coatings, indicating that its safety has been basically recognized by downstream industries. However, for environmental compliance in specific markets (such as EU REACH registration, RoHS directive, US TSCA, etc.), it is recommended that users apply for targeted compliance declarations from Guoli Chemical based on the requirements of their own end products' export or sales destinations.
Regarding test reports, the product database has published routine factory inspection items (including appearance, pH value, acid value, saponification value, hydroxyl value, moisture, heavy metal content, etc.), and these indicators are guaranteed by Guoli Chemical's internal quality control system. If you need formal COA (Certificate of Analysis), MSDS (Material Safety Data Sheet), third-party test reports, or specific substance test data, please clearly state your requirements to Guoli Chemical business personnel when ordering, and the company will provide corresponding documents according to specific needs.
| Indicator Item | Value/Status | Environmental Significance |
|---|---|---|
| Acute toxicity | Low oral acute toxicity | Low risk to human health |
| Heavy metal content | ≤20 mg/kg | Meets general chemical environmental standards |
| Arsenic content (As) | ≤2 mg/kg | Strictly controlled harmful element |
| Flammability | Non-flammable (flash point >200°C) | Low storage and transportation safety risk |
| Moisture | ≤1.0% | Product stable, not easily degraded |
| Acid value | ≤5 mgKOH/g | High product purity, few by-products |
| Biodegradability | No clear data in database | Requires separate testing or declaration |
| REACH compliance | No registration information in database | Please contact Guoli Chemical for confirmation |
For applications with high environmental requirements (such as cosmetics and textile auxiliaries exported to the EU), the following measures are recommended:
