Abstract
The development of biodetergents based on natural ingredients is a more environmentally friendly alternative. Water eutrophication and health problems are the impacts of using synthetic detergents. This study aims to develop a biosurfactant-based biodetergent formulation from starfruit leaf extract (Averrhoa bilimbi Linn.) and to evaluate the physicochemical properties of the resulting product. Through the extraction of starfruit leaf saponins, a biosurfactant will be obtained, which is then formulated with Decyl glucoside and lauryl glucoside. The physicochemical properties of the resulting detergent were tested, including pH, density, viscosity, foam stability, spreadability, and homogeneity, in accordance with the Indonesian National Standard (SNI) for liquid detergents. The results show that variations in the formulation affect the pH, density, and viscosity of the biodetergent. All biodetergent products had pH values ranging from 10.53 to 10.92 and densities of 1.023-1.049 g/mL, which met the requirements of SNI 06-476-1996. The resulting foam stability was around 81.7%, close to the value of commercial detergents, and all formulations showed good spreadability and homogeneity.
