What is Tridecyl ethyleneglycol monoether?
Tridecyl ethyleneglycol monoether (CAS 24938-91-8) is a nonionic surfactant derived from tridecyl alcohol and ethylene oxide. Also marketed as Trideceth and classified under E1300.
Where is Tridecyl ethyleneglycol monoether used?
- Industrial and personal care formulations: emulsifier, dispersant and cleaning agent, tunable via degree of ethoxylation
- Textile and leather processing: scouring and degreasing agent removing oils and contaminants from fiber and hide surfaces before dyeing or finishing
- Personal care: emulsion stabilizer in creams, lotions and cleansing products, with foam modulation
- Industrial cleaning concentrates: soil dispersion and rinsability on hard surfaces and equipment
- Paper processing: dispersant and process aid controlling pitch deposits and improving coating uniformity
Good to know: Low-EO grades typically present as liquids and higher-EO grades as waxy solids or pastes. Common variants like Trideceth-6 or Trideceth-10 are selected based on HLB requirements of the target formulation.
