Trideceth-7 carboxylic acid

Trideceth-7 carboxylic acid (CAS 68412-55-5) is a mild, ethoxylated ether carboxylic acid derived from a branched tridecyl alcohol base with seven ethylene oxide units. It functions as an anionic surfactant, providing emulsification, foam control, and detergency across a broad range of formulated products.

In personal care, it is used in shampoos, facial cleansers, and body washes where mildness to skin and compatibility with other surfactant systems are priorities. Home care and industrial cleaning formulations rely on it for hard surface cleaners and degreasers.

The chemical is particularly effective in alkaline systems where its performance remains stable. Textile processing operations use it as a wetting and scouring agent to ensure even penetration of treatment liquids into fiber substrates.

In leather and paper processing, it supports surface modification and emulsification of processing aids during wet finishing stages. This versatility makes it a staple ingredient for manufacturers seeking reliable performance in diverse industrial environments.

Trideceth-7 carboxylic acid is typically supplied as a liquid or low-viscosity paste, depending on concentration and temperature. It is available in technical and cosmetic grades, with cosmetic-grade material meeting purity requirements.

These standards are suitable for leave-on and rinse-off personal care applications. Standard commercial concentrations are commonly offered in the range of 90–100% active content to ensure maximum efficiency for the end user.
