When using PEG400DO, focus on protecting skin, eyes and respiratory tract. Wear full personal protective equipment, avoid direct contact and inhalation of vapors/mists.

Detailed Description

PEG400DO (Polyethylene Glycol 400 Dioleate) is a low-toxicity nonionic surfactant with an acute oral toxicity LD50 > 5000 mg/kg (rat), indicating overall low toxicity. However, according to the Guoli Chemical product safety data, this product is still classified by GHS as Skin irritation (Category 2), Eye irritation (Category 2), and Specific target organ toxicity - single exposure (Category 3, respiratory irritation). Therefore, adequate attention must be given during handling and use.

In actual use, PEG400DO is a light yellow to amber liquid with a flash point above 200°C. Vapor volatilization is low at room temperature, but during heating, stirring, or spraying operations, mists or vapors may be generated, which can cause respiratory discomfort if inhaled. Its ester bond structure is prone to hydrolysis under alkaline conditions, so it should avoid being mixed, stored, or used with strong alkaline substances to prevent additional risks from decomposition products.

Application Recommendations

When using PEG400DO in scenarios such as textile oil compounding, metalworking fluid formulation, personal care product manufacturing, and pesticide formulation processing, it is recommended to operate in a well-ventilated environment. If heating for melting or prolonged stirring is required, activate local exhaust ventilation to reduce accumulation of vapors or mists in the air. The product is a low-foaming surfactant, not prone to generating excessive foam during stirring, but attention should still be paid to splashing risks.

Precautions

  • Personal Protection: Must wear chemically resistant protective gloves (e.g., nitrile gloves), safety goggles/face shield, and protective clothing. If necessary, wear an organic vapor respirator.
  • Storage Conditions: Store sealed in a cool, dry, well-ventilated place, away from strong alkaline substances and strong oxidizing agents, to avoid hydrolysis and deterioration of ester bonds.
  • Spill Handling: For small spills, cover and collect with inert absorbent materials (e.g., sand, vermiculite); for large spills, contain and pump into dedicated containers, prevent entry into sewers or waterways.
  • Ecological Impact: May cause harmful effects to aquatic organisms, but the product is readily biodegradable, resulting in low environmental burden after proper disposal. Waste treatment should comply with local regulations; do not discharge arbitrarily.
  • First Aid Measures: For skin contact, immediately wash with plenty of soap and water; for eye contact, rinse with water for at least 15 minutes, seek medical attention if irritation persists; for inhalation, move quickly to fresh air, seek medical attention if respiratory discomfort occurs.
