Emulsifier A-110 (oleic acid polyoxyethylene ester · OEO-110) is a nonionic surfactant classified by GHS as a non-hazardous substance or mixture. Its acute oral toxicity LD50 (rat) is >2000 mg/kg, which is practically non-toxic, with no sensitization or mutagenicity. Under normal use conditions, it does not cause significant acute health hazards and has a high operational safety margin.
Although the toxicity is very low, this product has slight irritancy to skin and eyes. Therefore, caution must still be exercised during handling. It is recommended to wear chemical protective gloves (e.g., nitrile rubber, thickness >0.3 mm, breakthrough time >480 min) and close-fitting safety goggles. If there is a risk of splashing, impermeable work clothing should also be worn. Hands and any other potentially contacted areas must be thoroughly washed after handling. Eating, drinking, or smoking is prohibited in the work area.
The product has good biodegradability and can decompose relatively quickly in the environment after use, with minimal ecological impact. However, it must not be disposed of by pouring into sewers or water bodies. Disposal should be carried out by a licensed waste treatment facility in accordance with local and national regulations, with incineration being the recommended method.

Personal Protective Equipment (PPE): Before handling, familiarize yourself with the substance's properties and strictly follow chemical safety operating procedures. For hand protection, use butyl rubber or nitrile rubber gloves (thickness >0.3 mm). Wear close-fitting safety goggles or a face shield for eye protection. If ventilation is insufficient or in the presence of aerosols or heating operations, use appropriate respiratory protection (e.g., respirator with organic vapor cartridges). Eyewash stations and emergency showers should be available in the work area.
Storage Requirements: Store in a cool, dry, well-ventilated warehouse, away from heat and ignition sources. Keep containers tightly closed and avoid contact with strong oxidizers. The recommended storage temperature is 5°C to 35°C. Prevent freezing or excessively high temperatures that could cause product deterioration. The storage area should be equipped with spill containment trays or dikes to prevent leakage. Avoid storage with food or feed.
Transportation Notes: This product is not classified as dangerous goods, so transport conditions are relatively relaxed. During transport, ensure containers are sealed to prevent leakage. Avoid transporting in the same vehicle with strong oxidizers. No special regulatory requirements.
