Span S-20 lauric acid (sorbitan monolaurate) is classified as a Xi irritant chemical. Its hazard symbol is Xi (irritant), and the R phrases are R36/37/38, indicating irritation to eyes, respiratory system, and skin. Although this product is not classified as dangerous goods under current regulations, it must still be managed strictly in accordance with chemical specifications during industrial operations. Prolonged or repeated contact may also cause skin defatting and mild irritation, so it should not be taken lightly.
During operation, ensure good ventilation in the workplace, and install local exhaust ventilation if necessary. For personal protection, chemical safety goggles, nitrile rubber or neoprene gloves, and long-sleeved work clothes must be worn. When there is a risk of splashing or exposure to high concentrations of vapor, a combination filter mask for particulates/organic gases should also be worn. Eating, drinking, and smoking are strictly prohibited in the workplace. Wash hands and exposed skin thoroughly after handling and before breaks. Containers should be resealed immediately after use to prevent vapor accumulation and impurity intrusion. Pregnant and lactating women, as well as individuals with a history of skin allergies, should avoid direct contact.
For storage, keep the product in a cool, dry, well-ventilated dedicated warehouse, away from heat sources, sparks, and open flames. The storage temperature is recommended to be between 5°C and 35°C, avoiding freezing or prolonged high temperatures that may affect the product's emulsifying properties. Packaging materials should preferably be stainless steel, polyethylene, or lined iron drums. Avoid using copper and its alloys. The product should not be stored for more than 24 months from the date of manufacture.
| Risk Category | Specific Hazard | Protective Measures |
|---|---|---|
| Eye Contact | Irritant, R36 | Wear chemical safety goggles; in case of accidental contact, immediately flush with plenty of water for at least 15 minutes and seek medical attention |
| Respiratory System | Irritant, R37 | Ensure adequate ventilation; if necessary, wear a combination filter mask for particulates/organic gases |
| Skin Contact | Irritant, R38; prolonged contact may cause defatting | Wear nitrile rubber or neoprene gloves and long-sleeved work clothes |
| Ingestion | Gastrointestinal irritation | Rinse mouth with water immediately; do not induce vomiting; drink 1-2 glasses of water to dilute; seek medical attention immediately |
| Fire | Combustible but not explosive | Use dry powder, carbon dioxide, water fog, or alcohol-resistant foam for extinguishing; do not use a direct water jet |
Skin Contact: Immediately remove contaminated clothing and wash with plenty of running water and soap for at least 15 minutes. If irritation persists or redness occurs, seek medical attention.
Eye Contact: Immediately hold eyelids open and rinse thoroughly with plenty of water or saline solution for at least 15 minutes. During rinsing, move the eyes in all directions to ensure thorough cleaning of the conjunctival fornix. Seek medical attention as soon as possible and present this safety information (S26).
Inhalation: Move the affected person to fresh air immediately, keep the airway clear, and keep warm and at rest. If breathing is difficult, administer oxygen immediately; if breathing stops, trained personnel should perform artificial respiration and seek medical attention immediately.
Spill Disposal: Evacuate unauthorized personnel. After operators put on protective equipment, cut off the leak source. Use inert absorbent materials (such as vermiculite, dry sand, diatomaceous earth) to contain and collect the spilled liquid. Place waste in sealed containers and dispose of in accordance with local regulations. Avoid discharge into sewers or waterways.
