AEO‑7(Fatty Alcohol Ethoxylate 7EO)CAS 68439-50-9

Fatty Alcohol Ethoxylate AEO-7 (CAS 68439-50-9) is a versatile non-ionic surfactant chemically defined as the polyethylene glycol ether of C12-C14 fatty alcohol with approximately 7 moles of ethylene oxide , functioning primarily as a high-performance detergent and penetrating agent. With an HLB value of approximately 12, this colorless to pale yellow liquid (or paste) is fully soluble in water and offers an optimal balance between wetting speed and emulsification power. It is extensively utilized in liquid laundry detergents for its ability to remove oily stains at low temperatures and in the textile industry as a scouring agent and dye-leveling auxiliary. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications (varying Cloud Point and pH) for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.
