Formulation, characterization and in vitro evaluation of proshine MBTMGMIHS herbal sunscreen cream containing flower extract

The primary goal of this research was to develop and test a herbal sunscreen cream containing Hibiscus (Hibiscus rosasinensis) and Rose flower extracts (Rosaceae). Hibiscus and Rose extractswere used in the formulation of oil in water (O/W) emulsion-based cream. Flower extracts were preparedusing the Soxhlet apparatus. The physicochemical parameters of the formulated herbal sunscreen creams were tested, including colour, odour, spreadability, pH, and viscosity.The centrifugation process was used to conduct the stability and sensitivity tests. A UV Spectrophotometric method of Mansur et al. was used to calculate the in-vitro SPF of the formulations. The flower extract-based sunscreen cream provided high absorbance in the 290-320nm wavelength range, with an SPF of 38.12-42.24. The ProShine MBTMGMIHS herbal formulation was found to be stable, spreadable, homogeneous, non-greasy, and displayed no signs of phase separation. The pH of the cream was found to between 5.5-6 which is nearer to the skin's pH.Also, after the microbial evaluation of ProShine MBTMGMIHS herbal sunscreen, no bacterial or fungal contamination was observed after incubation for a long period.We may assume from the study's findings that the formulated sunscreen can greatly improve and add to the UV absorption properties of conventional sunscreen formulations. It would also aid in the broadening of the sunscreen's UV defence performance, with the added benefit of preventing the negative and undesirable effects of synthetic sunscreen compounds.
