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.

It functions as an emulsifier, dispersant, and detergent active across formulation-intensive industries where both surface activity and mildness are required for high-performance applications.

In personal care, it emulsifies oil-in-water systems in rinse-off and leave-on products, contributing mild cleansing alongside moisture retention on skin and hair surfaces.

Household and industrial cleaning formulations use it as a degreasing surfactant capable of solubilizing oily soils at moderate concentrations while maintaining stability in various environments.

Textile processing benefits from its dispersing action during dyeing and finishing operations, where it helps maintain dye bath uniformity and prevents re-deposition of removed soils.

Leather and paper treatment processes employ it to improve wetting and even distribution of treatment agents across fibrous substrates for consistent and high-quality results.

Polyethylene glycol carboxymethyl octyl ether is typically supplied as a liquid or viscous solution. Concentration and PEG chain length variants are available to meet specific HLB requirements.

Technical-grade material is the standard commercial offering, with specifications confirmed on a supplier-by-supplier basis to ensure compatibility with diverse industrial formulation targets.
