How to store Peregal O-50/100? How long is the shelf life?

Peregal O-50/100 should be stored sealed in a cool and dry environment below 40°C. Under proper storage conditions, the shelf life is typically 2 years.

Detailed Explanation

Peregal O-50/100 (fatty alcohol polyoxyethylene ether, CAS: 68439-49-6) is a high-polymerization degree nonionic surfactant with excellent chemical stability and good tolerance to acids, alkalis, hard water, and oxidizing agents. According to Guoli Chemical product safety data, its flash point is above 200°C, and it is not classified as a dangerous chemical. The product is very stable under compliant storage conditions. The product packaging specification is 20kg woven bag. After opening, it should be resealed properly to prevent moisture absorption and caking.

Regarding shelf life, the Guoli Chemical product database does not currently provide official shelf life data for this product. However, based on industry standards and the physicochemical properties of fatty alcohol polyoxyethylene ether nonionic surfactants, under strict compliance with the following storage conditions, the recommended use period for unopened products is generally 2 years from the production date. For products exceeding this period, it is recommended to conduct small-scale tests to verify key performance indicators such as emulsifying power and solubility before use. If performance is satisfactory, normal use can continue.

Application Suggestions

Since Peregal O-50/100 (O-50 melting point approx. 40-45°C, O-100 melting point approx. 45-50°C) may experience softening or slight caking in high summer temperatures, this is a physical change and does not affect product quality. It is recommended:

• Follow the first-in-first-out principle to avoid long-term accumulation of inventory
• Seal unused product immediately after opening, expel air from the bag, and tighten the bag mouth with a sealing clip or tie
• If slight caking occurs, crush before use and dissolve normally; performance is not affected
• If the product color significantly darkens, develops odor, or becomes turbid upon dissolution, discontinue use and conduct quality testing

Notes

• Avoid storage at excessively high temperatures; high temperatures may cause decomposition and produce irritating fumes (carbon monoxide, carbon dioxide, etc.)
• Empty bags may contain product residues; do not use for storing food or feed
• If leakage occurs, collect with inert materials such as sand or vermiculite, seal properly, and prevent entry into drains or water bodies
• Storage area should be equipped with fire-fighting equipment (water spray, dry powder, or carbon dioxide extinguisher); flash point is above 200°C, not flammable at room temperature
