    Application Areas

    Industrial lubricants, degreasing agents, and plastic sol viscosity stabilizers.
    Preparation of textile softener, antistatic agent, and dry cleaning agent.
    Oil based cutting fluid balance emulsifier, metal processing lubricant additive.

    Storage conditions

    Temperature: The temperature of the storage tank should be controlled between 30-80 ℃ (if it is in barrels, it is recommended to store it in a cool, dry, and low-temperature warehouse to avoid decomposition caused by high temperatures).
    Packaging: Iron drums (20kg, 200kg) or specialized tank trucks, sealed and stored to prevent air and moisture from entering.
    Environment: Well ventilated, away from sources of fire, heat, and oxidants (such as strong acids and alkalis).
    Light exposure: Avoid direct sunlight, it is recommended to use brown bottles or opaque materials for packaging.

    Safety precautions

    Personal protection: Wear safety goggles, anti-static work clothes, and rubber gloves during operation.
    Operation standard: Handle with care to prevent collision or leakage.
    Fire fighting measures: extinguishing medium: dry powder, carbon dioxide, foam extinguisher.
    Disposal: Refer to local regulations and entrust to professional institutions for disposal to avoid arbitrary disposal.

    FAQ - Technical & Supply Chain

    • Q:

      What is Polyethylene Glycol 400 Monooleate used for?

      A: PEG‑400 Monooleate is used as a nonionic emulsifier and dispersant in textile processing, metalworking fluids, agrochemical formulations, and industrial cleaning products. It provides stable O/W emulsions and good solubilization of hydrophobic components.
    • Q:

      Do PEG 400 monooleate and polyethylene glycol oleate correspond to the same product?

      A: Yes. PEG 400 monooleate and polyethylene glycol oleate refer to the same substance. Both names describe the monoester of PEG‑400 with oleic acid, commonly used as an emulsifier in industrial applications.
    • Q:

      Is Polyethylene Glycol 400 Monooleate intended for industrial formulation use?

      A: Yes. This product is designed for use as a formulation ingredient in industrial applications including emulsion stabilization, dispersion of oils and active ingredients, and as a processing aid in various chemical manufacturing processes.
    • Q:

      What is the HLB value of PEG‑400 Monooleate?

      A: PEG‑400 Monooleate typically has an HLB value in the range of 11–13, making it suitable as an O/W emulsifier. The HLB can vary slightly depending on the fatty acid composition and degree of esterification.
    • Q:

      Can PEG‑400 Monooleate be blended with other emulsifiers?

      A: Yes, PEG‑400 Monooleate can be blended with other nonionic, anionic, or cationic surfactants to achieve specific HLB values and emulsion characteristics. It is commonly used in combination with fatty alcohol ethoxylates or glycerol esters.
    • Q:

      What quality indicators should buyers verify when sourcing PEG‑400 Monooleate?

      A: Key quality indicators include acid value, saponification value, hydroxyl value, water content, and appearance. These parameters ensure consistent emulsification performance and batch uniformity in downstream applications.
