Precautions for the use of stearic acid polyoxyethylene ether SG-6?

Stearic acid polyoxyethylene ether SG-6 is a low-toxicity, non-irritating nonionic surfactant. During use, special attention should be paid to dust protection, eye protection, and storage condition control.

Detailed Description

Stearic acid polyoxyethylene ether SG-6 (PEG-6 Stearate) is a relatively safe nonionic surfactant. Its acute oral toxicity LD50 is greater than 2000 mg/kg (rat), classified as low toxicity; the primary skin irritation index PII is less than 0.5, non-irritating to the skin; the skin sensitization rate is 0%, non-sensitizing. These toxicological data indicate that the health risk of this product is low under normal industrial use conditions.

It should be noted that this product may cause mild reversible irritation to the eyes; rabbit tests show that it may cause conjunctival congestion and edema, usually recovering within a few days. Therefore, eye protection should be emphasized during operation. In addition, the product is a white to slightly yellowish waxy solid or flake at room temperature. When dust is generated during feeding and weighing, dust protection should be taken.

From the perspective of physical and chemical safety, the flash point of this product is greater than 150°C (closed cup), so it is non-flammable, does not burn when exposed to open flame, and has no fire or explosion risk. However, it should still be kept away from ignition sources and heat sources. Its chemical properties are stable; it does not saponify or hydrolyze in acidic or alkaline media and hard water conditions. But storage separately from strong oxidants, strong acids, and strong alkalis is a basic safety requirement.

Operation and Protection Requirements

Storage Essentials

• Temperature Control: Storage temperature should be maintained between 15°C and 35°C to avoid changes in material properties caused by extreme temperatures.
• Sealed Moisture-proof: Keep containers tightly closed to prevent moisture absorption and contamination.
• Segregated Storage: Store separately from oxidants, strong acids, and strong alkalis; do not mix storage.
• Ventilated and Dry: Store in a cool, dry, well-ventilated warehouse.

Emergency Treatment

Skin Contact: Immediately remove contaminated clothing and rinse thoroughly with plenty of running water and soap. If irritation or rash occurs, seek medical attention.

Eye Contact: Immediately lift the eyelids and rinse thoroughly with running water or saline for at least 15 minutes. If irritation persists, seek medical attention immediately.

Inhalation: Quickly move the person to fresh air and keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately and seek medical attention.

Ingestion: Rinse mouth thoroughly with water, do not induce vomiting, seek medical attention immediately and show the product container or label.

Precautions

• Operators must be specially trained and strictly follow operating procedures.
• Maintain good ventilation in the working area; use local exhaust ventilation if necessary.
• Eating, smoking, or drinking is strictly prohibited in the workplace; wash hands thoroughly after operation.
• In case of spills, absorb and collect with inert materials such as sand or vermiculite, and prevent entry into drains or soil.
• This product is readily biodegradable (OECD 301B, degradation rate >60% in 28 days), low toxicity to aquatic environment, but still avoid direct release into water bodies.
• This product is non-flammable, but thermal decomposition may produce carbon monoxide, carbon dioxide, and irritating fumes. Firefighters must wear positive-pressure self-contained breathing apparatus.
