Stearic Acid Polyoxyethylene Ether SG-40 (PEG-40 Stearate) is not classified as a hazardous substance or mixture under the GHS classification. Its acute oral toxicity is very low (rat LD50 > 5000 mg/kg), it is non-irritating to skin and eyes (verified by OECD 404/405 standards), has no skin sensitization (OECD 406), and shows no mutagenicity or reproductive toxicity. Under normal usage conditions, the product poses minimal risk to human health.
Despite its high safety profile, this product is still an industrial chemical. At room temperature, it appears as a white to yellowish waxy solid (melting point approximately 30-40°C). During operation, care should be taken to avoid burns from melting at high temperatures. The product is non-flammable (flash point > 200°C), non-explosive, non-oxidizing, and chemically stable under normal conditions. However, when exposed to fire and heat decomposition, it may release carbon monoxide, carbon dioxide, and a small amount of irritating vapors, so it should still be kept away from open flames.
In terms of the environment, this product has low toxicity to aquatic organisms (fish LC50 > 100 mg/L) and exhibits excellent biodegradability, complying with OECD 301 standards, and is not prone to long-term accumulation in the environment. Undiluted product should not be discharged in large quantities directly into water bodies or sewers to avoid impacting wastewater treatment systems.
| Storage Requirement | Specific Instructions |
|---|---|
| Warehouse Conditions | Cool, dry, well-ventilated, away from heat sources, flames, and direct sunlight |
| Temperature Range | Recommended 5°C ~ 35°C, prevent melting and caking at high temperatures or solidification and deterioration at low temperatures (melting point approx. 30-40°C) |
| Packaging Containers | Keep containers tightly closed; use original packaging or containers made of stainless steel or plastic; reseal after opening to avoid moisture absorption |
| Incompatible Materials | Avoid storage with strong oxidizers (e.g., peroxides, perchlorates) |
| Shelf Life | Typically 12 months under proper storage conditions (from date of manufacture); expired products need to be retested before determining usability |
Immediately rinse with plenty of water and soap for at least 15 minutes, remove contaminated clothing. The product itself is non-irritating, but rinsing effectively removes residues. If irritation persists, seek medical attention.
Rinse gently with flowing water or saline solution for at least 15 minutes, keeping eyelids open. If discomfort persists, seek medical attention.
Rinse mouth immediately, do NOT induce vomiting, drink 1-2 glasses of water to dilute. If large amounts are ingested or discomfort occurs, seek medical attention immediately and present the product safety data sheet.
For small spills, absorb with inert absorbent material (e.g., sand, vermiculite) and collect in a closed container; for large spills, dike and contain, transfer using a pump to a spare container. Avoid generating high-concentration wastewater when cleaning residues; collect and dispose of in accordance with local regulations. Prevent spills from entering drains, waterways, or soil.
The product is non-flammable but may decompose when exposed to fire. Use water fog, foam, dry powder, or carbon dioxide for extinguishing. Firefighters should wear self-contained breathing apparatus and full protective clothing.
Waste from the product is considered non-hazardous. It can be incinerated or landfilled according to local regulations, or sent to a licensed waste treatment facility. High-temperature incineration (with energy recovery and exhaust gas purification systems) is recommended. Uncontaminated packaging can be recycled; contaminated containers should be disposed of in the same manner. Verify national and local environmental regulations before disposal.
