Preparation And Evaluation of Herbal Facewash Tablet Using Rosa Gallica and Multani Mittti

In recent years, there has been a growing demand for herbal cosmetic products due to increased awareness regarding the harmful effects associated with synthetic chemicals. Herbal cosmetics are formulated using natural ingredients obtained from plants, minerals, and other naturally occurring substances, making them safer, eco-friendly, and suitable for long-term use. These products not only enhance physical appearance but also provide therapeutic benefits while maintaining the natural balance of the skin.

Skin is the largest organ of the human body and serves as a protective barrier against environmental pollutants, microorganisms, and harmful ultraviolet radiation. Exposure to dust, pollution, excess oil, and microorganisms often leads to skin problems such as acne, pimples, irritation, and dullness. Therefore, regular cleansing of the skin is essential to maintain healthy and attractive skin. Conventional facewash products generally contain synthetic surfactants, preservatives, and chemicals that may cause dryness, irritation, and allergic reactions in sensitive individuals.

Herbal facewash tablets have emerged as an innovative alternative to conventional liquid facewashes. These tablets are compact, water-free formulations prepared by compressing herbal ingredients along with suitable excipients into a solid dosage form. They offer several advantages, including easy portability, reduced packaging waste, improved stability, lower preservative requirements, and convenience during travel. Upon contact with water, the tablets disintegrate rapidly to produce a cleansing lather that effectively removes dirt, oil, and impurities from the skin. Multani Mitti (Fuller’s Earth) is a natural clay widely used in cosmetic preparations because of its excellent oil-absorbing, cleansing, cooling, and skin-purifying properties. It helps remove excess sebum, dirt, and dead skin cells, making it especially beneficial for oily and acne-prone skin. Rosa gallica, commonly known as rose, possesses antioxidant, soothing, anti-inflammatory, and skin-refreshing properties that help improve skin texture and provide a natural glow.

The combination of Multani and Rosa gallica in a tablet dosage form provides a synergistic effect, offering deep cleansing along with skin nourishment and rejuvention. The successful formulation of such tablets requires careful selection of excipients to ensure adequate hardness, stability, rapid disintegration and overall user acceptability.

EVALUATION PARAMETER

To evaluate the prepared formulation evaluation tests like visual appearances, physicochemical properties, pH, hardness and various other tests were done.

1. Organoleptic properties

Colour: The colour of herbal facewash tablet was analyzed visually and found light brown colour

Odour: Checked to ensure the scent is pleasant and free from chemical

Apperance: The colour of herbal facewash tablet was checked and visually and found uniform consistency.

Texture: The texture of herbal facewash tablet was smooth and non-gritty           

2. Consistency

Commercial and lab-formulated Multani Mitti tablets achieve their solid yet soluble consistency. They maintained a rigid solid state while remaining readily soluble upon application. The tablet remains stable during storage but undergoes rapid disintegration when introduced to an aqueous medium for use.

3. Cleaning Ability

Solid tablet face washes formulated with Multani Mitti are highly effective at providing deep cleansing, particularly for oily and acne-prone skin. It is remove sebum dirt and impurities from the skin, this confirm that product actually perform its intended job of deep cleaning.

4. Weight variation

According to IP (Indian Pharmacopoeia), 20 tablets were taken for the weight variation test. Each tablet is weighed individually using an electronic balance. The average weight is then calculated, and the deviation is recorded by comparing each individual weight with the average value.

Small variations in weight are negligible and can be accepted. However, the weight variation limit should not exceed ± 7.5%                   

5. Hardness test

The ability of a tablet to withstand for mechanical shock is known as hardness. Pfizer hardness tester is the instrument which is used to determined the hardness of tablet. Three to five tablets are randomly selected, their hardness is tested and the result are recorded. Tablets should have an average hardness 3 to 8.

6. Thickness test

A Vernier calliper is used to measure the thickness of tablets. To measure tablet thickness, place the tablet vertically between the jaw of calibrated vernier caliper, close the jaws gently until they touch the tablet surface without compressing or crushing it and then record the measurement of the tablet should be in limit of +5.

7. Friability test

Roche friabilator is the equipment which is used for the determination of friability (W initial). Note down the initial weight of the tablets individually. Tablets are placed in a plastic chamber which revolves at 25 rpm and they are subjected to fall from a height of 6 inches in the friabilator for about 100 revolutions.Then measure the weight ofthe tablet (Wfinal) and observe anyweight difference before tablet after the friabilator processing.

Limit: loss in weight less than 0.5 to 1% of the initial weight of the tablet should be considered as acceptable limits.

Formula: (initial weight-final weight)/ initial weight x 100

8. pH test

The pH of the tablet was calculated by using a digital pH meter by dissolving the tablet in distilled water and measuring the pH on the pH meter. The pH of 5% aqueous solution of the formulation was measured by using a calibrated digital pH meter at room temp. It can be done by making 15 aqueous solution of formulation and measure by using calibrated digital pH meter at constant temp.

9. Spreadability test

The spreadability of the tablet was tested in laboratory by rubbing the tablet on hand with water. The tablet placed in hand with few drops of water in palm to activate it, rub the formulation in circular motion and observe how smoothly it spread. The spreadability was found to be good.

10. Foamability test

Foamability test of the tablet was done by rubbing the tablet on both hands using water and observing the amount of foam formed.

Take 25ml water in a 50ml of cylinder and drop the tablet in the cylinder and cover the cylinder with hand and shake it vigorously for new min. measure the volume of the foam produced.

11. Irritancy test

Crush the facewash tablet and dissolve it in a predetermined, standardized volume of distilled water, mix until a uniformed paste solution is formed. Ensure the dorsal surface of your left hand is clean and dry. Make a specific 1 cm2 area on skin. Apply uniform layer of facewash tablet formulation to these marked area. Leave for 1-2 hrs. Observe it periodically 15 min intervals. Watch any symptoms like redness and irritation. After application no irritation or redness will found.

12. Washability test

Washability of facewash tablet can be determined by applying the formulation on the skin and wash with water and check manually. The facewash tablet can be easily and completely removed from skin without leaving a sticky or oily residue.

RESULT
