Polyoxyethylene tridecyl ether phosphate

Polyoxyethylene tridecyl ether phosphate (CAS 9046-01-9) is an anionic phosphate ester surfactant derived from ethoxylated tridecyl alcohol. Also marketed as Tryfac 610A, Stepfac 8181, and Stepfac 8180.

Where is Polyoxyethylene tridecyl ether phosphate used?

• Industrial and formulated products: emulsifier, dispersant, detergent
• Personal care: cleansing formulations
• Textile processing: scouring and wetting agent removing oils, sizing agents and contaminants from fiber and fabric
• Agricultural formulations: emulsifier and dispersant in herbicide and pesticide concentrates
• Leather and paper processing: degreasing hides and improving surface treatment penetration
• It improves active ingredient distribution and tank-mix stability.
• Functions as a surfactant, reducing the surface tension of cosmetics and helping the product spread uniformly during use.
• Used in personal care industrial hand cleaners and heavy-duty degreasers, providing high cleaning performance with skin compatibility.
• In paper production it controls the dispersion of resin and oil in process waters.

Good to know: The acid or salt form determines its specific physical properties.
