In accordance with the instant invention, a water-based hydraulic fluid, having improved anti-wear and corrosion inhibition properties can be obtained by blending neodecanoic acid with a conventional water-based hydraulic fluid composition.

Water-based hydraulic fluids having improved lubricity and corrosion

In accordance with the instant invention, a water-based hydraulic fluid, having improved low foaming properties can be obtained by blending 2-ethylhexanol with a conventional water-based hydraulic fluid composition.

Water-based low foam hydraulic fluid employing 2-ethylhexanol defoamer

Hydraulic fluids or metalworking lubricants are prepared utilizing mixture of water and, as lubricants and corrosion inhibitors, an alkyl dialkanolamide, a polyoxyethylene ester, and an ethoxylated alkylaryl phosphate ester. The compositions have improved extreme pressure lubricating and wear preventing characteristics and are non-flammable. The compositions can be thickened if desired using a polyglycol-type thickener and can contain conventional corrosion inhibiting and extreme pressure lubricating additives known in the prior art. Stable concentrates comprising a phosphate ester, a polyoxyethylene ether, and an alkyl alkanolamide can be prepared.
