Polyoxyethylene laurate ester LAE-4 (PEG-4 Laurate) is a nonionic surfactant, classified as a low-toxicity chemical under normal use conditions, with no significant health hazards and it is not a flammable liquid or solid. However, prolonged or repeated contact may cause skin dryness, defatting, or mild irritation. If it decomposes under high temperature, it may produce irritating or harmful fumes such as carbon monoxide and carbon dioxide, so standardized operation is still required.
This product has chemical stability against acids, alkalis, and hard water, and has good compatibility with anionic, cationic, and other nonionic surfactants, making it extremely flexible in formulation. However, in actual formulation or operation, direct mixing with incompatible substances such as strong oxidizers, strong acids, and strong alkalis should still be avoided to prevent unwanted chemical reactions.
In addition, the product is biodegradable and has good eco-friendliness, but large spills entering water bodies may cause temporary adverse effects on aquatic organisms. During operation and waste disposal, attention must be paid to environmental protection to prevent entry into drainage systems and surface waters.

Skin contact: Immediately remove contaminated clothing and thoroughly rinse with plenty of running water and soap for at least 15 minutes. If redness, swelling, pain, or persistent irritation occurs, seek medical attention immediately.
Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Keep eyes rotating during rinsing. Be sure to seek medical examination.
Inhalation: Quickly move to fresh air and keep the airway open. If breathing is difficult, administer oxygen and seek medical attention immediately.
Ingestion: Immediately rinse mouth with clean water, do not induce vomiting, seek medical attention promptly.
Spill handling: For small spills, cover and collect with inert absorbent material (such as sand, vermiculite). For large spills, build dikes to contain, prevent entry into sewers or water bodies, cover with foam to suppress vapors, and use an explosion-proof pump to transfer to a dedicated container.
