As an accredited Stearic Acid factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Stearic Acid is typically packaged in 25 kg white woven plastic bags with inner polyethylene lining, clearly labeled with product information. |
| Shipping | Stearic Acid is shipped in tightly sealed bags, drums, or bulk containers to prevent moisture ingress. It should be stored and transported in a cool, dry, well-ventilated area away from incompatible substances. Proper labeling and adherence to hazardous material regulations ensure safe and compliant transportation. Avoid exposure to direct sunlight and heat. |
| Storage | Stearic acid should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and sources of ignition. Keep containers tightly closed and properly labeled. Avoid contact with strong oxidizing agents. Use storage containers made of compatible materials, such as stainless steel or polyethylene, to prevent contamination. Maintain storage temperature below 50°C to ensure product stability and quality. |
