Explain the Cleansing Action Of Soaps and Detergents
Dec 01, 2020·The cleansing action of both soaps and detergents results from their ability to lower the surface tension of water, to emulsify oil or grease and to hold them in a suspension in water. This ability is due to the structure of soaps and detergents. In water, a sodium soap dissolves to form soap anions and sodium cations.

Mode of Action. The most feasible explanation for the antimicrobial action of alcohol is denaturation of proteins. This mechanism is supported by the observation that absolute ethyl alcohol, a dehydrating agent, is less bactericidal than mixtures of alcohol and water because proteins are denatured more quickly in the presence of water 484, 485 .
