PEG200MO (Polyethylene Glycol 200 Monooleate) should be stored in a cool, dry, well-ventilated warehouse. The recommended ambient temperature is 5°C to 35°C. Keep the container tightly closed, away from heat sources and incompatible substances.

Detailed Description

PEG200MO is a non-ionic surfactant with stable chemical properties and is not classified as a hazardous chemical. However, under improper storage conditions, the product may undergo phase separation, moisture absorption, degradation, or performance changes. To ensure at least 12 months of stability from the date of production, it is recommended to strictly follow the storage specifications below and implement a first-in, first-out inventory management principle.

This product has certain hygroscopic properties. Long-term exposure to high-humidity environments will cause it to absorb moisture from the air, potentially leading to a decline in product performance. In addition, although the product has an open-cup flash point greater than 200°C and is not classified as a flammable liquid, it is still recommended to keep it away from open flames and heat sources to maximize storage safety.

Storage PeriodAt least 12 months from the date of production under recommended conditions

Application Recommendations

In actual use, it is recommended to adopt a first-in, first-out inventory turnover principle and regularly inspect the appearance of the product in stock (normal appearance is a light yellow to yellow viscous liquid). If the product experiences layering or turbidity due to low-temperature environments, it can be slowly warmed to room temperature before use with moderate stirring; this usually restores uniformity without affecting product performance.

Precautions

  • Empty containers may have product residues and should not be used to hold other materials until thoroughly cleaned.
  • Avoid releasing the product into drainage systems, waterways, or confined spaces to prevent environmental pollution.
  • Prolonged exposure to freezing conditions may cause irreversible phase separation of the product, affecting its usability.
  • After opening, the product should be used as soon as possible to minimize contact with air and reduce the risk of moisture absorption.
