Eosin requirement in tallow soap is about 40-50% which fastens the lather formation, softens the hard soaps and increases its cleansing action
Soap powder is prepared by mixing soap with hydrated sodium carbonate
Detergents differ from soaps in their action in hard water
Tarnish inhibitor (e.g., Benzotriazole) is added in soap to facilitate the removal of stains due to tea, blood etc
