Soaps

SOAPS VS Detergents


  • Soaps are sodium salts of long chain carboxylic acids.
  • Detergents are sodium salts of long chain sulphonic acids.

  • Soaps do not form leather with hard water.
  • Detergents form leather with hard water.

  • Soaps are biodegradable.
  • Detergents are non biodegradable.

  • Soaps do not have strong cleansing action.
  • Detergents have strong cleansing action.

  • Soaps are prepared from animal fats.
  • Detergents are prepared from hydrocarbons of petroleum.

Advantage of soaps over detergents :
Soaps are biodegradable so they do not produce pollution. 
While detergents being non biodegradable produce pollution.

Advantage of detergents over soaps :


Detergents can be used in hard water. Also, they have strong cleansing action. While soaps have weak cleansing action and they cannot be used in hard water.
