What safety precautions should be taken when using Castor Oil Polyoxyethylene Ether EL-12?

Castor Oil Polyoxyethylene Ether EL-12 is non-hazardous, low-toxicity, and non-irritating, but routine chemical handling procedures should still be followed, with focus on personal protection, storage conditions, and emergency response.

Detailed description

Castor Oil Polyoxyethylene Ether EL-12 (CAS No.: 61791-12-6) is a non-ionic surfactant derived from natural castor oil, with overall good safety. Toxicological data show an oral LD50 in rats > 5000 mg/kg and dermal LD50 > 2000 mg/kg, classifying it as practically non-toxic; it is non-irritating to skin and eyes, and non-sensitizing to skin. The product has a flash point > 200 °C (closed cup), is a non-flammable liquid, has low toxicity to aquatic organisms, and is readily biodegradable. These characteristics make it relatively safe to use, but caution should still be exercised.

In practical handling, although the product has high safety, prolonged or heavy exposure may still cause discomfort. It is recommended to use in a well-ventilated area; if ventilation is inadequate, wear appropriate respiratory protection. Must wear protective gloves, safety glasses, and protective work clothing to avoid splashes onto skin and eyes. After handling, thoroughly wash exposed areas. Do not eat or drink in the work area. Wash hands after contact with the product before touching other items to prevent indirect contamination.

For storage, keep the product in a cool, dry, well-ventilated warehouse, and keep containers tightly sealed to prevent moisture absorption. Storage temperature should be controlled between 5-40 °C, avoiding extreme heat or freezing that could affect product quality. Keep away from incompatible materials such as strong oxidizers, strong acids, and strong bases. It is recommended to use corrosion-resistant containers such as stainless steel, polyethylene, or plastic-lined iron drums. Avoid long-term outdoor storage to prevent rain and sun exposure.

Emergency response key points

Leak emergency treatment

• Small leaks: Absorb with inert absorbent materials such as sand, vermiculite, etc., collect in a sealed container and dispose according to regulations.
• Large leaks: Dike to contain, prevent spreading to sewers or waterways. Transfer to a spare container using an explosion-proof pump for recovery or disposal. Ventilate the leak area and flush residues with plenty of water; collect flush water into the wastewater treatment system.

Firefighting measures

• The product is a non-flammable liquid, but may decompose at high temperatures generating irritating fumes.
• In case of surrounding fire, use water spray, foam, dry powder, or carbon dioxide to extinguish.
• Firefighters should wear self-contained breathing apparatus and full protective clothing, and avoid directing water streams directly at the leaking material.

First aid measures

Application recommendations

In daily formulation use, EL-12, as an O/W emulsifier, is widely used in cosmetics, pesticide formulations, textile auxiliaries, metalworking fluids, and industrial cleaners. Determine the dosage based on the specific formulation system and pay attention to compatibility with other surfactants. As a non-ionic type, it can be widely compounded with anionic, cationic, and non-ionic auxiliaries, but long-term stability should be evaluated when used with strong acid or strong base systems.

Notes

• Avoid direct discharge of leaked material into the environment; although low-toxic, it may cause local eutrophication.
• Transport and store as non-hazardous goods, but still comply with general chemical storage regulations.
• Use the product as soon as possible after opening; seal unused portions to prevent moisture absorption and deterioration.
