Abstract
Soaps are made from fats and alkali, which forms glycerine. Detergents when mixed with water can attack dirt and separate the dirt from soiled fabrics. Hard water, which has higher concentrations of calcium and magnesium, requires stronger detergents than regular soap for proper cleaning. It is necessary to match the detergent with the hardness of water.
