Methodology:

Formulation table:

Formulation procedure:

1. Weigh the components:

Using a digital balance, precisely weigh each of the following ingredients: rice flour, shea butter, coconut oil, sodium benzoate, liquid papain, curcumin extract, and aloe vera gel.

2. Melt the butter:

Fill a clean China dish with the weighed shea butter. Make sure it turns into a clear liquid by melting it in a water bath at 70 to 75°C.

3.  Add coconut oil:

To create a consistent oily phase, add the coconut oil to the dish once the shea butter has completely melted and stir well.

4. Add an exfoliant:

To guarantee even dispersion and prevent lump formation, gradually add the rice flour to the melted liquid while stirring constantly.

5. Add Active Ingredients and Cool:

Let the mixture cool slightly (to around 40°C or below) before adding the liquid papain and curcumin extract. To equally distribute the active ingredients, stir lightly yet thoroughly.

6. Include the Aqueous Phase:

Gradually whisk in the aloe vera gel until the mixture is creamy and smooth.

7. Add preservative:

Lastly, use sodium benzoate as a preservative and stir until the mixture is uniform.

8. Packaging and labeling:

After the scrub is ready, put it in a sanitized, sealed container. For later usage or evaluation, properly label and store at room temperature.

Evaluation Tests:

1. Organoleptic characteristics:

The appearance and colour were observed by visual examination. The odour was examined by smelling it.

2. Viscosity test:

The viscosity of the scrub was measured using Brookfield Viscometer, spindle no- 62 was selected to measure the viscosity. The spindle no- 62 was fixed to the Brookfield’s Viscometer. Immerse the spindle inside the beaker containing scrub up to mark. Set the torque of the viscometer to 20 rpm. The viscosity of the scrub was displayed on a digital indicator, and the reading was noted.

Fig: Brookfield’s Viscometer

3. PH:

A pH meter is used to measure the alkalinity or acidity of the product. It is important to check the pH to make sure the scrub is within range and match the pH of the skin. The pH of the scrub was determined by using a systonic digital pH meter. The pH of the formulation was measured using a calibrated digital pH meter. The electrode was immersed in the sample, and the reading was taken at a constant temperature.

Fig: pH meter

4. Homogeneity:

The homogeneity of the formulated scrubs was tested by pressing a small quantity of the scrub between the thumb and index finger.

5. Washability:

The washability of the scrub was examined by applying a small quantity of scrub on the skin and wash with water, then noting the result.

6. Spreadability:

The spreadability test evaluates the spreading capacity of the scrub. About 1g of scrub was placed between two glass slides, and 100 gm of weight was placed on the slides. After 60 sec the time taken for the scrub to spread on the slide was measured. The result was obtained by applying a specific formula,

S= ????×???? ????

Where,
