Laureth-6 carboxylic acid

Laureth-6 carboxylic acid (CAS 220622-96-8) is an ether carboxylate surfactant derived from ethoxylated lauryl/myristyl alcohol with a carboxymethyl head group.

Where is Laureth-6 carboxylic acid used?

• Personal care: low-irritation cleansing in shampoos, facial cleansers and body washes, compatible with amphoteric co-surfactants
• Industrial and institutional cleaning: degreasing hard surfaces where mildness toward substrates or operator skin contact is required
• Textile processing: scouring and emulsifying agent that removes oils and sizing agents from fiber
• Leather and paper processing: interfacial tension control
• It improves wetting during wet-processing stages.

Good to know: It combines mild surfactancy with pH-dependent ionization, making it effective in both acidic and alkaline formulation environments.

Commercial specifications
