Lauryl Polyoxyethylene Ether LAE-4 (Polyoxyethylene (4) laurate) is a nonionic surfactant with high safety. It is not classified as a flammable liquid or solid and has no explosion hazard. In conventional industrial and personal care applications, its risk to human health is low. However, prolonged or repeated contact may cause skin dryness, defatting, or mild irritation. If decomposed at high temperatures, it may produce irritating or harmful fumes such as carbon monoxide and carbon dioxide, so operating temperatures should not be too high.
This product has good compatibility with anionic, cationic, and other nonionic surfactants. It is resistant to acids, alkalis, and hard water. Under normal storage conditions (5°C to 35°C, dry and ventilated, container sealed), the shelf life is two years. After the shelf life, it can only be used after passing inspection.
Immediately remove contaminated clothing. Rinse the affected area thoroughly with plenty of running water and soap for at least 15 minutes. If redness, swelling, pain, or persistent irritation occurs, seek medical attention immediately.
Immediately lift the eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. During rinsing, rotate the eyeballs to ensure thorough cleaning of the conjunctival sac. Seek medical examination without delay.
Move the affected person to fresh air immediately and keep the respiratory tract unobstructed. If breathing difficulties occur, administer oxygen and seek medical attention. If breathing stops, perform artificial respiration immediately and call for emergency medical assistance.
Rinse the mouth with water immediately. Do not induce vomiting. If the victim is conscious, give a small amount of water to dilute the stomach contents. Seek medical attention promptly, and bring this safety instruction or product label for reference.
Small spills: Cover with inert absorbent material (e.g., sand, vermiculite) and collect into a closed container for disposal as waste. Large spills: Immediately shut off the leakage source, construct dikes or dig pits to contain the spill, and prevent it from entering sewers, surface water, or groundwater. Cover the spill liquid with foam to suppress vapor generation. Use explosion-proof pumps to transfer to dedicated collection containers. Set up warning signs in the spill area, and prohibit entry by non-emergency personnel. Dispose of the spill and contaminated cleaning materials harmlessly according to local regulations.
This product is not flammable, but it may decompose when heated in a fire, producing harmful gases. Suitable extinguishing media: water spray, alcohol-resistant foam, dry powder, carbon dioxide. Firefighters must wear self-contained positive-pressure breathing apparatus and full fireproof and chemical-resistant clothing. Move containers from the fire area to a safe location if possible; if not, cool exposed containers with water spray.
This product is biodegradable, but large spills into water bodies may cause temporary adverse effects on aquatic organisms. Prevent it from entering drainage systems, surface water, and groundwater. Dispose of waste product and contaminated containers in accordance with national and local hazardous waste management regulations. High-temperature incineration with appropriate exhaust gas purification is recommended.
