Polyethylene glycol distearate 400DS is a nonionic surfactant. Based on available toxicological data, its oral median lethal dose (LD50) is greater than 2000 mg/kg, dermal LD50 greater than 2000 mg/kg. It does not fall into acute toxicity categories and does not meet the classification threshold for any GHS hazard category; thus, GHS hazard classification is not required. The product is not significantly irritating to the skin, has no known sensitizing potential, and there is no evidence of mutagenicity, carcinogenicity, or reproductive toxicity.
Although the product itself is relatively safe, precautions should be taken during handling: the product is a white to slightly yellow waxy solid that may generate dust during pouring, weighing, and other operations. If dust comes into direct contact with the eyes, it may cause mild discomfort due to mechanical friction (not classified as serious eye damage). Additionally, under high temperature or combustion conditions, the product may decompose to produce gases such as carbon monoxide and carbon dioxide; therefore, it should be kept away from open flames and excessively high temperatures.
Environmentally, the product is readily biodegradable, meeting OECD 301 series criteria for ready biodegradability. It has low toxicity to aquatic organisms (EC50/LC50 for fish, crustaceans, and algae all greater than 100 mg/L) and low bioaccumulation potential. Nevertheless, spills should be prevented from entering sewers and surface waters.
| Item | Specific Requirements |
|---|---|
| Dust Control | Avoid generating and inhaling dust; if the operation is prone to dust generation, local exhaust ventilation or general ventilation should be provided. |
| Personal Hygiene | Wash hands and contacted skin thoroughly with soap and water after handling; do not eat, drink, or smoke in the work area. |
| Hand Protection | Recommend wearing nitrile rubber or natural rubber gloves. |
| Eye Protection | If there is a risk of splashing, recommend wearing chemical safety goggles. |
| Respiratory Protection | No special protection required under normal operations; if dust is generated, recommend wearing a particulate respirator meeting GB 2626 or N95 standards. |
| Storage Temperature | Store in a cool, dry, well-ventilated warehouse, recommended between 5°C and 40°C. |
| Incompatible Materials | Strong oxidizers. |
| Avoid Conditions | Heat sources, sparks, open flames, excessively high temperatures. |
Skin Contact: Immediately remove contaminated clothing and flush the affected area with plenty of soap and water. Seek medical attention if discomfort or skin reaction occurs.
Eye Contact: Immediately flush with flowing water or saline for at least 15 minutes, lifting the upper and lower eyelids. Seek medical attention if discomfort persists.
Inhalation: Move the person to fresh air and keep the airway clear. Seek medical attention if symptoms occur.
Ingestion: Rinse the mouth with water; do not induce vomiting. If the person is conscious, give a small amount of water to dilute stomach contents. Seek medical attention if discomfort occurs, and present the product safety data sheet or label.
Spill Handling: Use inert absorbent materials (e.g., sand, vermiculite, diatomaceous earth) to contain and collect the spill, and place in a sealed container. Avoid discharge into sewers, surface water, and groundwater systems. Clean the contaminated area with water or conventional cleaning agents.
