Low Foam Hydrotrope Phosphate Ester

Cola®Fax 3611 is a low-foaming organic phosphate ester surfactant that provides effective hydrotroping properties in highly built liquid detergent formulations. Due to its compatibility and chemical stability in concentrated alkaline builder systems, it is particularly useful as a solubilizer for nonionics and other surfactants in high electrolyte applications. Cola®Fax 3611 is compatible for use in hypochlorite containing formulations.

Cola®Fax 3611 is stable in up to 35% sodium hydroxide solution.
