Aqueous machining fluid compositions, especially aqueous metalworking fluid compositions, are provided that exhibit improved reduction of friction and forces in the mechanical shaping and working of metallic and solid non-metallic workpieces. These compositions comprise a) water, b) a sulfurized organic material selected from the group consisting of sulfurized unsaturated aliphatic carboxylic acids having from 6 to 22 carbon atoms and salts thereof, sulfurized unsaturated esters of aliphatic carboxylic acids having 1 to 22 carbon atoms, sulfurized polymerized unsaturated fatty acids and salts and esters thereof, and mixtures thereof, c) a sulfurized hydrocarbon and d) an aliphatic ester of a dialkyldithiocarbamic acid.
