CAS 61788-85-0 Peg-40 is a non-ionic surfactant derived from hydrogenated castor oil through ethoxylation. It functions as an emulsifier and solubilizer, enabling stable oil-in-water emulsions in formulations. Widely used in cosmetics, personal care, and industrial applications where mildness and biodegradability are valued.

This grade is a polyethoxylated (PEG-40) version, offering higher solubility and lower viscosity than lower PEG grades. It integrates well into aqueous systems and supports cold processing, reducing energy costs in manufacturing. Typical applications include liquid detergents, creams, and agricultural adjuvants.

Not intended for use in systems requiring high thermal stability above 80°C or in strongly acidic environments. Always test compatibility with other ingredients before bulk use. Recommended storage is in a cool, dry place away from direct sunlight to prevent oxidation.

Best Fit & Nearest Alternatives

Best suited for:

• Cosmetic and personal care formulations
• Detergent and cleaning products
• Agricultural adjuvants and spray oils
• Pharmaceutical excipients and solubilizers

Not ideal for:

• Systems requiring high thermal stability above 80°C
• Strongly acidic environments (pH < 4)
• High-salt formulations prone to salting-out

Peg-40 offers better water solubility and lower viscosity than Peg-20, making it easier to handle in cold processes. Peg-60 is thicker and better for higher-viscosity emulsions but harder to pump and dose.

What Drives the Price

• Purity level and residual impurities
• Degree of ethoxylation (PEG chain length)
• Packaging type (drums vs. IBCs vs. bulk)
• Order volume and frequency

Pricing scales with MOQ and volume tiers. Lower MOQs carry higher per-unit costs. Request a formal quote for accurate tiered pricing based on your annual volume.

Lead Time, Shipping & Returns

• Lead time: Typical lead time is 15 - 30 days from confirmed order and payment. Confirm with supplier for exact timing based on order size and seasonal demand.
• Shipping: Available via sea freight (FCL/LCL), air freight, or courier for samples. Supplier supports EXW, FOB, and CIF terms depending on destination.
• Returns & defects: Returns accepted only for confirmed defects or shipping damage. Inspect shipment upon arrival. Report discrepancies within 7 days of receipt with photographic evidence. Supplier arranges return at buyer’s expense unless defect is confirmed.

Handling & Application Notes

• Use nitrile or PVC gloves when handling undiluted material to avoid skin irritation.
• Heat gently to 50 - 60°C if viscosity is too high for pumping; do not exceed 70°C to prevent degradation.
• Compatible with anionic, cationic, and non-ionic surfactants; conduct compatibility testing before scaling.
