Polyethylene glycol carboxymethyl octyl ether

Polyethylene glycol carboxymethyl octyl ether (CAS 53563-70-5) is a nonionic–anionic hybrid surfactant combining a PEG backbone with a carboxymethyl head group and an octyl tail.

Where is Polyethylene glycol carboxymethyl octyl ether used?

• Personal care: emulsifier of oil-in-water systems in rinse-off and leave-on products, with mild cleansing and moisture retention
• Household and industrial cleaning: degreasing surfactant that solubilizes oily soils at moderate concentrations
• Textile processing: dispersing action during dyeing and finishing, maintaining dye bath uniformity and preventing re-deposition
• Leather and paper treatment: improves wetting and even distribution of treatment agents on fibrous substrates
• It functions as an emulsifier, dispersant, and detergent active.

Commercial specifications

• Concentration and PEG chain length variants meet specific HLB requirements
