Abstract

Scrub is a type of cosmetics that has been widely used for skin care. However, many women do not realize that among the cosmetic products, including the scrubs they usually use, they may contain dangerous ingredients such as heavy metals. The use of scrubs, especially traditional scrubs that contain ingredients from nature, allows heavy metal contamination. This study aims to validate the analysis method of cadmium heavy metal content in traditional scrubs in the city of Tasikmalaya. Sample preparation used the wet digestion method using HNO3: H2O2 (3: 1). Cadmium was analyzed by Atomic Absorption Spectrophotometry at a specific wavelength of 283.3 nm, respectively. After obtaining the optimum digestion process and tools, the cadmium method was validated with Atomic Absorption Spectrophotometry (AAS) which included linearity tests, detection limits, quantification limits, precision and accuracy. The results of the validation of the analysis method obtained a linear calibration curve in the concentration range of 1-8 ppm with a linear regression equation y = 0.1237x + 0.0247, the value of the correlation coefficient = 0.9982. The detection and quantitation limits were 0.63 ppm and 2.11 ppm. Intra-day and inter-day precision is SBR <2%. The retrieval or accuracy obtained is 101.64 - 105.49%.

Abstract

Sapodilla fruit (Manilkara zapota) which is often used by the community as an antibacterial drug is part of the sapodilla plant. Sapodilla contains saponin, tannin, and flavonoid compounds which can be as antibacterial so it is suspected to be able to inhibit the growth of bacteria that cause dental caries. The purpose of this study was the Evaluation of Sawo Extract Mouthwash Formulation as an Antibacterial. The sample used was sapodilla fruit which had been extracted using the infusion method. The formulation of sapodilla fruit extract mouthwash was evaluated with the extract concentration of sapodilla fruit (Manilkara zapota) 1%, 5% and 10%. The results of this study obtained the most stable formulation with a concentration of extract of sapodilla fruit (Manilkara zapota) 1%. Â
