Polyether defoamer GP-330 (glycerol polypropylene ether, CAS: 68439-50-9) has multiple advantages in terms of environmental compliance. According to the safety data in Guoli Chemical's product database, this product is clearly classified as a non-hazardous substance, with strong physiological inertness and no known significant hazard classifications. In terms of ecotoxicity, this product shows low toxicity to aquatic organisms, meeting the basic requirements of current green chemical products.
In terms of biodegradability, GP-330, as a polyether nonionic surfactant, contains polyoxypropylene segments in its molecular structure that are relatively hydrophobic, but the overall structure gradually degrades in the environment over a certain period of time. The product itself is non-flammable (flash point >200℃), and does not generate VOC emissions during normal storage and use, complying with VOC restriction regulations. Heavy metal content is strictly controlled (Pb ≤10 mg/kg, arsenic ≤2 mg/kg).
It should be clarified that although the product has good environmental performance, it is classified as a slightly hygroscopic substance. Waste disposal should be handled by professional institutions in accordance with local regulations, and should not be directly discharged into water environments. The product itself does not contain harmful substances such as APE or silicone that are restricted in European and American countries.
| Parameter | Index | Environmental Significance |
|---|---|---|
| Heavy metals (as Pb) | ≤10 mg/kg | Complies with RoHS, REACH and other regulations |
| Arsenic (As) | ≤2 mg/kg | Far below hazardous substance thresholds |
| Flash point (open cup) | >200℃ | Non-flammable, reducing fire risk |
| Ecotoxicity | Low toxicity to aquatic organisms | Reduces risk of water pollution |
| Hazard class | Non-hazardous substance | Convenient for transport and storage |
| pH value (1% aqueous dispersion) | 5.0~8.0 | Near neutral, environmentally friendly |
GP-330, as a high-efficiency defoamer specifically designed for water-based systems, is suitable for industries such as coatings, adhesives, inks, papermaking, and water treatment. In scenarios with strict environmental requirements (e.g., green building coatings, food packaging paper), this product is an ideal choice due to its low ecotoxicity and non-hazardous properties. The recommended dosage is typically 0.1% to 0.5% of the total system weight, and the specific amount should be adjusted according to actual process conditions to achieve an optimal balance between defoaming effect and cost.
