DDT is manufactured by the condensation of chlorobenzene with chloral at 30°C in presence of oleum, which is a highly exothermic reaction
Chloral is obtained by the chlorination of ethyl alcohol

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
