Nonionic Glycerol Propoxylate-block-Ethoxylate CAS 9082-00-2 Surfactant

Glycerol propoxylate-block-ethoxylate (CAS:9082-00-2,EINECS:208-750-2, HS Code:39072090, molecular formula: C₈H₂₂O₇, typical MW:2,600-5,300 g/mol) is a nonionic polyether triol block copolymer synthesized by sequential anionic polymerization of propylene oxide (PO) followed by ethylene oxide (EO) onto a glycerol initiator core, yielding a gPPO-b-PEO architecture. Our product is available as a colorless to pale yellow viscous liquid or paste with excellent surface activity and hydrophilic-lipophilic balance (HLB) control. We supply customized grades with varying EO/PO ratios (typically 15% EO, 85% PO) and molecular weights to meet diverse application requirements. It is fully compliant with international standards for industrial surfactants, polyurethane intermediates and personal care ingredients. This product is soluble in water, ethanol and most organic solvents, with a cloud point typically between 20-60°C depending on molecular structure.

Applications
Polyurethane Industry (Core Application)
Reactive intermediate for flexible and rigid polyurethane foam production, improving foam rise profiles and flexibility
Key component in polyurethane elastomers, coatings and adhesives, enhancing mechanical properties and hydrolytic stability
Provides controlled reactivity and cell structure regulation in foam manufacturing processes
Surfactant & Emulsification Applications
Nonionic emulsifier for oil-in-water (O/W) and water-in-oil (W/O) emulsions in paints, inks and coatings
Efficient defoamer and anti-foaming agent in industrial processes, water treatment and detergent formulations
Wetting agent and dispersant for agricultural pesticides, improving spray coverage and active ingredient absorption

Product Advantages
✅ Customizable HLB balance: Tailored EO/PO ratios for specific emulsification and solubility requirements
✅ Superior performance: Ordered block structure provides lower cloud points and better substrate penetration than random copolymers
✅ Dual functionality: Reactive hydroxyl groups enable chemical modification while surfactant properties enhance formulation stability
✅ Broad compatibility: Works well with ionic and nonionic surfactants, solvents and polymers
✅ Biodegradable: Environmentally friendly with good biodegradability profiles
✅ Consistent quality: Strict batch testing ensures stable hydroxyl value, viscosity and acid value across production runs

Packaging & Storage
Standard packaging: 200kg iron drums with inner PE lining, 1000kg IBC tanks or ISO tank containers for bulk shipments. Store in a cool, dry, well-ventilated warehouse at 5-35°C.
