Oleth-5 is a low-toxicity nonionic surfactant, but it poses risks of skin/eye irritation and respiratory tract irritation. Operators must wear complete personal protective equipment and use it in a well-ventilated environment.

Detailed Description

Oleth-5 (Oleth-5) is a low-toxicity substance (oral LD50 >2000 mg\/kg) under normal use conditions, but its GHS hazard classification indicates: the product is classified as Skin Irritant Category 2 (H315), Serious Eye Irritant Category 2 (H319), and Respiratory Irritant Category 3 (H335), and it has long-term adverse effects on aquatic life (H412). This means that during use, direct skin contact, eye exposure, and inhalation of vapors or aerosols must be avoided.

The product has a flash point above 150°C (closed cup) and is not flammable at room temperature, but it can still be ignited under high temperature conditions, producing carbon monoxide, carbon dioxide, and irritating or toxic fumes when burned. Therefore, storage and handling should be away from heat sources, open flames, and other ignition sources, and contact with strong oxidizing agents (such as peroxides, permanganates, concentrated acids, etc.) should be avoided to prevent incompatible chemical reactions.

Personal Protective Equipment Requirements

According to the product Safety Data Sheet (SDS) requirements, the following protective equipment must be worn when handling Oleth-5:

Protected AreaProtective EquipmentStandard\/Material Requirements
Hand ProtectionChemically resistant protective glovesNitrile or neoprene rubber, compliant with EN374 standard, regularly check integrity and permeation time
Eye\/Face ProtectionSealed goggles or full-face shieldCompliant with EN166 standard
Skin and Body ProtectionChemical protective clothingImpermeable material, avoid direct skin contact
Respiratory ProtectionOrganic vapor\/particulate combination cartridge respiratorUse in insufficient ventilation or when there is a risk of aerosol generation

Safe Handling and Storage

Handling Requirements: The workplace should be equipped with local exhaust ventilation or a general ventilation system to ensure that the concentration of vapors or aerosols in the air is below occupational exposure limits. Keep the container tightly closed during operation and avoid inhaling vapors or aerosols. Eating, drinking, and storing food are prohibited in the work area. After operation, thoroughly wash hands and any body parts that may have come into contact with the product.

Storage Conditions: The recommended storage temperature range is 5–35°C. Avoid high temperature exposure, direct sunlight, and freezing environments to prevent product deterioration or separation. Store in a cool, dry, well-ventilated warehouse, keep containers tightly closed, and place on corrosion-resistant trays or leak-proof containment. Keep away from heat sources, sparks, open flames, and strong oxidizing agents. Do not store in the same area as food, feed, or drinking water sources.

Emergency Response Precautions

  • Skin Contact: Immediately remove contaminated clothing and rinse skin thoroughly with plenty of water and soap for at least 15 minutes; if irritation persists, seek medical attention.
  • Eye Contact: Immediately lift eyelids and rinse with flowing water or saline solution for at least 15 minutes, keeping eyes open; promptly seek ophthalmological medical treatment.
  • Inhalation: Quickly move the patient to fresh air, keep them quiet and warm; if breathing is difficult, give oxygen; if breathing stops, immediately perform artificial respiration and seek medical help.
  • Ingestion: Do not induce vomiting. Rinse mouth thoroughly with water, then immediately drink 1-2 glasses of water to dilute. Seek medical attention promptly and present the safety data sheet to the physician.
  • Spill Response: Evacuate non-essential personnel, eliminate all ignition sources, ensure adequate ventilation; contain and collect the spill with inert absorbent materials (such as sand, vermiculite, universal binder), and place in sealed chemical waste containers. Prevent spill from entering sewers, surface water, or groundwater systems.
  • Environmental Protection: This product is harmful to aquatic life with long-lasting effects (H412). Do not discharge into natural water bodies. Disposal must be carried out in accordance with local regulations.
