What is the critical step in the continental method of preparing emulsions?

  1. Adding oil to water

  2. Levigating gum with oil

  3. Triturating until a creamy white mixture is formed

  4. Adding water all at once

The correct answer is: Triturating until a creamy white mixture is formed

In the continental method of preparing emulsions, the critical step is triturating until a creamy white mixture is formed. This step helps in achieving a stable emulsion by ensuring proper incorporation and dispersion of the oil and water phases. By triturating, the particle size of the dispersed phase is reduced, leading to a smooth and uniform mixture, which is essential for the formulation of an emulsion.
