Isotridecyl alcohol ethoxylate phosphate ester

Isotridecyl alcohol ethoxylate phosphate ester (CAS 73038-25-2), also referenced commercially as Ester phosphorique, is an anionic surfactant derived from the phosphation of ethoxylated isotridecyl alcohol.

Where is Isotridecyl alcohol ethoxylate phosphate ester used?

• Metalworking and industrial cleaning: lubricity additive and corrosion inhibitor in aqueous cutting fluids and metal cleaning concentrates
• Textile processing: emulsifier and wetting agent in fiber preparation baths, scouring formulations and dyeing auxiliaries
• Water treatment: dispersing and emulsifying agent in process water and industrial effluent
• Coatings and adhesives: stabiliser in emulsion polymerisation and pigment dispersant in waterborne formulations
• It delivers emulsification, detergency, lubrication and corrosion inhibition.

Good to know: Ethoxylation degree varies across commercial grades to tune HLB and performance profile. Acid and salt forms are offered depending on the target application.
