Formulation and characterization of Aloe vera gel and tomato powder containing cream

Herbal cosmetics are a valuable gift of nature and their demand is increasing in the world market. They have good activity with no side effects as compared to synthetic cosmetics. Herbal cosmetics are beauty products and because of natural ingredients, they possess desirable physiological activities. The present research work aimed to formulate and characterize cost-effective herbal nourishment cream containing Aloe vera gel and tomato powder. Four formulations i.e. F1, F2, F3, and F4 were prepared with varying concentrations of Aloe vera gel and tomato powder, while the composition of the cream base was kept the same. The oil phase of the cream base consisted of liquid paraffin (5.0 ml), stearic acid (4.8 g) and coconut oil (3.0 ml). The aqueous phase consisted of triethanolamine (1.5 ml), glycerin (5.0 ml), citric acid (0.4 g), methylparaben (0.1 g), water (q.s.) and key ingredients. The concentration of Aloe vera gel was 2.0 ml, 4.0 ml, 6.0 ml, 8.0 ml and the concentration of tomato powder was 0.2 g, 0.4 g, 0.6 g, 0.8 g in F1, F2, F3, and F4 respectively. The characterization of the formulated creams was carried out by standard methods, such as homogeneity test, smear type, irritancy test, pH test, spreadability test and acid value test. The stability test was carried out at different temperature conditions at 40 °C, below 5 °C and room temperature. All creams were homogeneous, non-irritant and easily removable. The pH of creams was in the range of 7.3–7.6 which is safe for human skin. Spreadability was in the range of 9–13. Acid values of the prepared creams were 5.6, 5.6, 6.4 and 7.2 respectively. Stability was examined by two parameters, homogeneity and pH change. The economical herbal creams prepared by using fewer chemicals are good for skin with moisturizing properties. The efficiency of creams can be improved by increasing the concentration of Aloe vera gel and tomato powder.
