Tridecethcarboxylic acid

Tridecethcarboxylic acid (CAS 56388-96-6), also known commercially as an ether carboxylate surfactant, is a nonionic-anionic hybrid surface-active agent derived from tridecyl alcohol ethoxylates.

It delivers effective emulsification, mild cleansing, and degreasing performance across a broad pH range. This makes it a preferred choice where compatibility with sensitive substrates or formulation stability is critical.

In personal care, it functions as a mild primary or co-surfactant in shampoos, facial cleansers, and body washes. It is ideal where low irritation potential is a primary formulation requirement for the manufacturer.

Industrial and institutional cleaning formulators use it to build hard-surface cleaners and degreasers. These products must perform reliably in both alkaline and acidic conditions to ensure effective results.

Textile processing operations apply it as an emulsifier and wetting agent in scouring and dyeing auxiliaries. It is also utilized in fiber preparation baths to enhance the overall quality of the textile treatment.

In leather and paper processing, it supports uniform dispersion of treatment chemicals and improves substrate penetration. This ensures that the chemical additives are distributed evenly throughout the material.

Tridecethcarboxylic acid is supplied as a liquid or low-viscosity paste, depending on the degree of ethoxylation. It is available in technical and industrial grades with varying EO chain lengths for specific needs.

These variations affect the HLB value and application suitability for different industrial processes. Buyers typically source it in drums or IBC containers, with bulk availability from specialty surfactant producers.
