Defoamer King FAG470 (polyether-modified polysiloxane defoamer) has significant environmental advantages. According to the Safety Data Sheet (SDS), this product is judged not to be a hazardous chemical under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), with no hazard categories assigned, and no pictograms, signal words, or hazard statements required. Notably, the product is explicitly marked as no hazard to the aquatic environment, which is a relatively prominent environmental characteristic in the defoamer category.
The product adopts a non-ionic formula design, free from restricted substances such as APEO (alkylphenol polyoxyethylene ether). It disperses easily in water and does not cause adverse reactions with other chemicals in the system due to ionic charges. Additionally, the product has no known acute toxicity, is non-irritating to skin and eyes, and is safe and reliable during use. Under normal conditions of use, the product exhibits good chemical stability and does not readily produce harmful decomposition products.
From an application perspective, the product is widely used in industries such as water treatment, textile printing and dyeing, and papermaking, especially in municipal sewage and industrial wastewater treatment systems where it can be directly added. This indirectly verifies its environmental compatibility—products that do not meet environmental requirements would struggle to pass the process review of wastewater treatment systems.
| Parameter Name | Standard Value | Environmental Significance |
|---|---|---|
| Heavy Metal Content | ≤10 ppm | Far below general industrial limits, meeting environmental discharge requirements |
| Arsenic Content (As) | ≤2 ppm | Strict control of harmful elements to ensure water safety |
| pH Value (1% Aqueous Solution) | 5.0 ~ 8.0 | Nearly neutral, minimal impact on water acidity and alkalinity |
| GHS Hazard Classification | Not classified (non-hazardous) | No hazardous labeling required, no special restrictions for transport and storage |
| Aquatic Toxicity | No hazard to aquatic environment | Can be safely used in water treatment systems without affecting water ecology |
| Moisture Content | ≤1.0% | High active ingredient content, reducing additional environmental burden from inert carriers |
Defoamer King FAG470, as a mature industrial product manufactured by Guoli Chemical, has a complete factory inspection process and batch inspection records. Before leaving the factory, the product undergoes strict quality inspections, including but not limited to the determination of core indicators such as appearance, pH value, solid content, and defoaming performance. However, the current product database does not yet include electronic versions of third-party test reports (such as ROHS, REACH, SGS certification reports), so direct online download of reports is not available.
