Emulsifier SG-100 (PEG-100 Stearate) is a non-ionic surfactant. Based on existing toxicological and ecotoxicological data, this product has no GHS hazard classification and is not listed in the Catalog of Hazardous Chemicals. The acute oral LD₅₀ in rats is > 5000 mg\/kg, indicating practically non-toxic; primary skin irritation index < 0.5, no significant irritation; Ames test negative, no genotoxicity; 28-day biodegradation rate > 60%, readily biodegradable. Overall, this product is a low-toxicity, low-irritation safe raw material.
Despite the low safety risk, standard chemical operating procedures should be followed in industrial use. The operating area should be well-ventilated, and closed systems should be used for material transfer and feeding when process conditions permit. After operation, before eating, before smoking, and before using the restroom, hands must be thoroughly washed with soap and water. Work clothes should be stored separately, and eating, drinking, or smoking is prohibited during work and in the workplace to avoid cross-contamination.
In terms of personal protection, special respiratory protection is generally not required. However, if the operating environment is poorly ventilated or there is a possibility of aerosol formation, it is recommended to wear appropriate respiratory protective equipment. For prolonged or repeated contact, chemical-resistant gloves (e.g., nitrile or neoprene) are recommended. If there is a risk of splashing, safety goggles or a face shield should be worn. It is recommended to install emergency eyewash stations and safety showers near the operation point for emergencies.

Evacuate non-essential personnel. Response personnel should wear safety goggles, gloves, and protective clothing. Prevent spills from entering sewers, surface water, and soil. For small spills, absorb with inert absorbent material (e.g., vermiculite, dry sand) and collect in a covered container. For large spills, first dike or pump recovery, then treat residual with inert absorbent. Wash contaminated area with plenty of water and detergent, collect the washings thoroughly and dispose of in accordance with regulations.
This product is not flammable. Select extinguishing media based on the surrounding fire source. Use water spray, alcohol-resistant foam, dry powder, or carbon dioxide. Combustion may produce irritating gases such as carbon monoxide and carbon dioxide. Firefighters must wear self-contained positive-pressure breathing apparatus and full fire-protective clothing.
Store in a cool, dry, well-ventilated dedicated warehouse, away from direct sunlight, heat sources, and ignition sources. Recommended storage temperature is 5°C to 40°C, and should be maintained above the product's melting point to ensure good fluidity. Use sealed original containers or compatible storage tanks (e.g., stainless steel, polyethylene, or lined carbon steel). Keep away from incompatible materials such as strong oxidizers, strong acids, and strong bases. Do not cut, weld, or store other materials in empty containers before cleaning.
Dispose of waste product, contaminated containers, and absorbent materials in accordance with local and national waste management regulations. Incineration at high temperature with flue gas treatment is recommended. Do not discharge into sewers or the environment. Empty and clean containers before disposal.
