PEG600DO, Polyethylene Glycol 600 Dioleate, how to store? What is the shelf life?

PEG600DO should be stored in a cool, dry, and well-ventilated environment, tightly sealed to prevent moisture; the database has no official shelf life data, and it is generally recommended to use within 1-2 years under proper storage conditions.

Detailed Description

PEG600DO (Polyethylene Glycol 600 Dioleate) is a chemically stable non-ionic surfactant that is not prone to hydrolysis or deterioration under normal storage conditions. According to the product safety data from Guoli Chemical, its flash point is greater than 150°C (closed cup), making it a non-flammable liquid with high storage safety. To ensure long-term product performance stability, the core principles are moisture prevention, light avoidance, and keeping away from high temperatures and strong oxidizers.

Regarding shelf life, there are no official shelf life parameters for Polyethylene Glycol 600 Dioleate in the product database. Typically, for such polyethylene glycol fatty acid ester products, under intact factory seals and standard storage conditions, it is recommended to use within 1-2 years. If the product is opened and exposed to air or humid environments for a long time, it may gradually absorb moisture or oxidize, affecting emulsifying power and appearance; therefore, it should be used as soon as possible after opening.

Technical Parameters

Application Recommendations

PEG600DO is widely used in cosmetic creams and lotions, textile oils, metalworking fluids, pesticide formulations, and industrial cleaning. Before first use after long-term storage, the following simple checks are recommended:

• Appearance Check: Normally a light yellow to yellow liquid; if obvious stratification, turbidity, gelation, or significant darkening occurs, the product may have deteriorated.
• Performance Test: Take a small sample for emulsification or dispersion testing to verify if its emulsifying power and dispersibility meet formulation requirements.
• Odor Check: If there is a distinct rancid or irritating odor, the oleic acid group may have oxidized, and the product should not be used.

Precautions

• Keep the container tightly sealed; after opening, reseal immediately and store upright with the cap facing up to prevent leakage and moisture absorption.
• Store away from strong oxidizers and avoid prolonged exposure to high temperatures (>40°C) or direct sunlight.
• Follow the "first in, first out" principle, prioritizing earlier batches.
• No eating, drinking, or smoking in storage areas; wash hands thoroughly after handling.
• Disposal must comply with local environmental regulations; do not discharge into sewers, water sources, or soil.
