PEG600DO (Polyethylene Glycol 600 Dioleate) should be stored in a cool, dry, and well-ventilated environment, keeping the packaging sealed, avoiding direct sunlight and high temperatures, and keeping away from strong oxidizers.

Detailed Description

PEG600DO is a chemically stable nonionic surfactant. Although it is not classified as a hazardous chemical, proper storage conditions are essential to maintain product quality and extend its service life. The ester bonds in its molecular structure may undergo slow hydrolysis under extreme conditions (such as high temperature, high humidity, or strong acid/alkaline environments). Therefore, the storage environment must be controlled to ensure the product's emulsifying and dispersing performance is not affected.

The flash point of this product is greater than 150°C (closed cup), and it is not classified as a flammable liquid. However, it should still follow standard fire safety regulations and be kept away from open flames and high-temperature heat sources. Under recommended storage conditions, unopened original packaging products typically have a shelf life of more than 12 months.

Storage Condition Parameters

Storage ParameterSpecific Requirement
Recommended Temperature Range5°C — 40°C
Environmental RequirementCool, dry, well-ventilated warehouse
Light RequirementAvoid direct sunlight
Packaging SealKeep container tightly closed; reseal immediately after opening and taking material
Placement MethodPlace upright with lid facing upward to prevent leakage
Incompatible MaterialsStore away from strong oxidizers
Fire Prevention RequirementKeep away from high temperature and open flame sources
Moisture ProtectionKeep away from water vapor and humid environments

Application Recommendations

During industrial production use, it is recommended to follow the "first in, first out" principle. After each material withdrawal, seal the container promptly to avoid prolonged exposure to air. If the product becomes turbid or increases in viscosity under low-temperature conditions, this is a normal physical change. Allow the product to return to room temperature (approximately 20-30°C) and gently stir evenly before use; the product performance will not be affected.

Precautions

  • During winter storage, if the ambient temperature falls below 5°C, the product may solidify or separate. Before use, fully warm it up in a warm environment and mix evenly.
  • Do not store or place in close proximity to strong oxidizers (such as concentrated nitric acid, peroxides, etc.).
  • After opening the packaging container, prevent moisture and impurities from entering to avoid product contamination or slow hydrolysis.
  • In case of leakage, use inert absorbent materials such as sand, vermiculite, etc. to collect; disposal must comply with local environmental regulations.
