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.

It delivers emulsification, detergency, lubrication, and corrosion inhibition across a broad range of industrial formulations. In metalworking and industrial cleaning, it functions as both a lubricity additive and a corrosion inhibitor.

It is commonly used in aqueous cutting fluids and metal cleaning concentrates. Textile processors use it as an emulsifier and wetting agent in fiber preparation baths, scouring formulations, and dyeing auxiliaries.

These applications are ideal where controlled foam and substrate compatibility are required. Water treatment formulators incorporate it for its dispersing and emulsifying performance in process water and industrial effluent.

In coatings and adhesive systems, it stabilizes emulsion polymerization processes and improves pigment dispersion in waterborne formulations. This versatility makes it a staple in modern chemical manufacturing.

Isotridecyl alcohol ethoxylate phosphate ester is typically supplied as a liquid or viscous paste. The ethoxylation degree varies across commercial grades to tune HLB and the specific performance profile.

It is available in technical grade , with acid and salt forms offered depending on the target application. Drum and IBC packaging are standard for industrial supply volumes to ensure safe transport.
