Castor Oil Polyoxyethylene Ether EL-10 is a non-hazardous substance, but standard operating procedures must still be followed, with emphasis on eye and skin protection, cool and sealed storage, and avoiding inhalation of vapors or accidental ingestion.

Detailed Description

Castor Oil Polyoxyethylene Ether EL-10 is a nonionic surfactant with a flash point above 150°C, classified as a non-flammable liquid with low inhalation or ingestion toxicity. However, the product has mild irritant properties for the eyes and skin, and repeated or prolonged contact may cause defatting of the skin. Therefore, caution must be exercised during handling. Under normal usage conditions, the product is chemically stable, resistant to acids, alkalis, and hard water, but may decompose at high temperatures or in the presence of flames, releasing irritating gases such as carbon monoxide and carbon dioxide.

In practical applications, the lipophilic nature of EL-10 makes it especially suitable for W/O (water-in-oil) emulsion systems, playing a key role in pesticide emulsifiable concentrates, cosmetic creams, metalworking fluids, and other areas. When using, the dosage should be determined based on the specific formulation system and process requirements; typically, it needs to be fully dissolved and dispersed in the oil phase before subsequent emulsification operations to ensure emulsion quality and system stability.

Safe Operation and Storage Guidelines

Personal Protective Requirements

  • Wear chemical safety goggles and chemical-resistant gloves (nitrile rubber recommended) during operation
  • Wear appropriate protective clothing to avoid skin exposure
  • Use in well-ventilated areas; employ local exhaust ventilation if necessary
  • Thoroughly wash exposed skin after handling; contaminated clothing should be washed before reuse

Storage Conditions

  • Store in a cool, dry, well-ventilated warehouse, away from ignition sources and heat sources
  • Recommended storage temperature between 0°C and 40°C, avoid direct sunlight
  • Keep containers tightly sealed to prevent moisture absorption and contamination
  • Keep away from incompatible materials such as strong oxidizers and strong acids
  • Equip the storage area with spill containment equipment and absorbent materials

Emergency Procedures

Type of ContactAction
Skin ContactImmediately remove contaminated clothing, rinse skin with plenty of running water and soap for at least 15 minutes; seek medical attention if irritation persists
Eye ContactImmediately lift eyelids and rinse thoroughly with plenty of water or saline for at least 15 minutes; seek medical attention immediately
InhalationMove to fresh air immediately; keep airway clear; administer oxygen if breathing is difficult; if breathing stops, give artificial respiration and seek emergency medical help
IngestionDo NOT induce vomiting, rinse mouth with water; do not give any oral liquids; call poison control center or doctor immediately and seek medical attention

Spill and Fire Precautions

Small spills: cover with inert absorbent material (dry sand, vermiculite, or universal absorbent pads), collect into sealed containers and label; large spills: contain quickly, prevent entry into drains or waterways. For fire fighting: although this product is not flammable, applicable extinguishing agents include water fog, alcohol-resistant foam, dry chemical, and carbon dioxide; firefighters must wear positive-pressure self-contained breathing apparatus.

Application Prohibitions

Do not eat, drink, or smoke in work areas. Follow standard chemical handling procedures; maintain a clean working environment. Waste disposal must comply with local environmental regulations; do not discharge indiscriminately. This product is intended for industrial use only; it should not be used directly in food or pharmaceuticals without proper formulation design.
