Evaluation of Body Scrub from Boergesenia forbesii and Kaempferia galanga

Abstract

Abstract The use of cosmetics at this time prioritizes natural ingredients over synthetic materials. The materials that are often used and become potential are green seaweed and rhizomes. Boergesenia forbesii and Kaempferia galanga are two natural ingredients with bioactive content that is good for human skin. The combination of these two natural materials has never been studied. This study aims to evaluate the best formulation of body scrub preparations from these two natural ingredients. In this study, the ratio of B. forbesii and K. galanga was 1:1 (cream R1), 1:2 (cream R2), 2:1 (cream R3), and control (no added natural ingredients) (cream R0). The cream preparations were evaluated by viscosity, emulsion type, stability (emulsion), skin moisture, and irritation test. Viscosity values in cream preparations ranged from 22,500 cPs to 34,600 cPs. All the treatment belongs to the type of water soluble oil (O/W). Cream R3 was the best for the stability of emulsion (88.89%). The skin moisture parameter for R0, R1, R2, and R3 were 40.44%, 52.75%, 54.34%, and 57.55%, respectively. Based on the results of the irritation test on the skin (for all treatments), there were no volunteers who experienced signs of irritation such as rash, itching, and edema. So, the best formulation was cream R3, based on the evaluation of all parameters.
