Which of the following enhances leathering property of soap?

Options

A. Sodium carbonate
B. Sodium rosinate
C. Sodium stearate
D. Trisodium phosphate

Explanation

To determine which compound enhances the lathering property of soap, we can analyze each of the given options:

1. **Sodium Carbonate**: Sodium carbonate is commonly used in laundry soaps, primarily as a filler. While it has various functions, it does not specifically enhance the lathering property of soap.

2. **Sodium Rosinate**: Sodium rosinate is a type of gum that is known to enhance the lathering properties of soap. This makes it a suitable candidate for improving the foam and lather that soap produces when used.

3. **Sodium Stearate**: Sodium stearate is a specific type of soap, formed from the reaction of stearic acid with sodium hydroxide. While it is a soap, it does not enhance lathering properties; it is simply a component of soap.

4. **Trisodium Phosphate**: Trisodium phosphate is often used in detergent powders and liquid detergents as a builder. It serves to soften water and enhance cleaning efficiency, but it does not specifically enhance lathering properties.

Based on the analysis, the compound that enhances the lathering property of soap is **Sodium Rosinate**. Therefore, the correct answer is **option 2: Sodium Rosinate**.
