The effect of concentration and kind of detergent, and nature of oil‐on‐oil removal efficiency in hard water was studied. Maximum oil removal efficiencies are shown at the same water hardness for a given oil. As the concentration of detergents increases, the water hardness at maximum oil removal efficiency increases and the sharpness of the oil removal peak is lessened. A linear relationship between concentration of detergent and water hardness at maximum oil removal efficiency was found. This relationship is dependent on the nature of the oily soil and kind of detergent.
