Preparation and Evaluation of Liquid Paraffin Emulsion

  1. Dry mortar and pestle

    The mortar and pestle were flamed.

  2. Preparation of Primary emulsion

    Primary emulsion was prepared by taking oil, water and gum in the ratio of 3:2:1(Mineral oil).
    Triturate in one direction only.

  3. Preparation of Sodium benzoate solution

    Sodium benzoate was dissolved in water.

  4. Add excipients

    Sodium benzoate solution, vanillin, chloroform, and glycerin were added to the primary emulsion and triturated.

  5. Make up the volume

    Volume is made up with purified water.

What is the Dose, Category, Storage & Container and Category of Liquid Paraffin Emulsion

Dose: 10-30 ml

Category: Faecal softener/ Laxative

Container & Storage: Store in a well-closed container, away from light.

Labelling Directions: Shake well before use. Discard if two layers are seen.

The calculation for Primary Emulsion:

Dry gum method

Fixed Oil

Oil: Water: Gum 3 : 2: 1

Mineral Oil

Oil: Water: Gum 3 : 2: 1

Volatile Oil

Oil: Water: Gum 3 : 2: 1

What is the use of chloroform in liquid paraffin emulsion?
