Tridecyl ethyleneglycol monoether

Tridecyl ethyleneglycol monoether (CAS 24938-91-8), also marketed as Trideceth and classified under E1300, is a nonionic surfactant derived from tridecyl alcohol and ethylene oxide.

It functions as an emulsifier, dispersant, and cleaning agent across industrial and personal care formulations, with performance tunable by varying the degree of ethoxylation.

In textile and leather processing, it acts as a scouring and degreasing agent, removing oils and contaminants from fiber and hide surfaces prior to dyeing or finishing.

Personal care formulators use it to stabilize emulsions in creams, lotions, and cleansing products, where it also contributes to foam modulation for better performance.

In industrial cleaning concentrates, it improves soil dispersion and rinsability across hard-surface and equipment cleaning applications. Paper processing operations use it as a dispersant.

It serves as a process aid to control pitch deposits and improve coating uniformity. Tridecyl ethyleneglycol monoether is supplied as a liquid or paste depending on the ethoxylation degree.

Low-EO grades typically present as liquids and higher-EO grades as waxy solids or pastes. It is available in technical and industrial grades with specific ethoxylate chain lengths.

Common variants like Trideceth-6 or Trideceth-10 are selected based on HLB requirements of the target formulation to ensure optimal stability and performance in various chemical systems.
