DePHOS™ P-4LF is an alcohol ethoxylate-based phosphate ester in free acid form. It is an antiwear and extreme pressure additive for use in lubricating and rolling oils, and hydraulic and water based cutting fluids and is a very effective, low foaming hydrotrope in homecare and industrial cleaning applications, such as high alkaline cleaners, bottle washing and metal cleaners. DePHOS™ P-4LF also finds application in metalworking formulations as a corrosion inhibitor, lubricant and wetting agent. DePHOS™ P-4LF is of particular advantage in acidic solutions where, either alone or with mineral or organic acids, it combines hydrotropic properties with an enhanced cleaning performance.
