Which of the following enhances the leathering property of soap?

1. Sodium carbonate

2. Sodium rosinate

3. Sodium stearate

4. Trisodium phosphate

Hint: Sodium rosinate enhances the leathering property of soap

Sodium Rosinate provides highly stable emulsion over a wide range of water hardness

Shaving soaps contain glycerol to prevent rapid drying. While preparing these soaps, a gum called rosin is added to them. It

forms sodium rosinate which lathers well. Laundry soaps contain fillers like sodium silicate, borax, and sodium carbonate.

Trisodium polyphosphate is an important filler added to detergent powders and liquid detergents.
