Exposure to sunlight and air pollution can adversely affect skin health, encouraging the development of natural skin care products. This study aimed to determine the selected formula for a cream body scrub containing areca nut powder (Areca catechu L.). This experimental study involved three formulations with varying stearic acid concentrations of 17%, 16.5%, and 16%, and triethanolamine concentrations of 2%, 2.5%, and 3%. The physical characteristics of the formulations were evaluated through organoleptic, homogeneity, pH, emulsion type, viscosity, and adhesion tests. The evaluation results showed that Formula II, containing 16.5% stearic acid and 2.5% triethanolamine, exhibited a characteristic mineral oil odor, good homogeneity, a pH of 7.58, an oil-in-water (O/W) emulsion type, a viscosity of 34,000 cP, and an adhesion time of 7.4 seconds. It can be concluded that Formula II was the selected formulation because it met all physical evaluation criteria for the areca nut powder cream body scrub based on the parameters assessed, indicating its potential for further development as a natural cosmetic product.
