The Mixing of Ethanol Extract of Terminalia catappa L in Transparent Soap Base to maintaining it's the Organoleptic properties, Solid quality and Inhibition of Staphylococcus aureus

Staphylococcus aureus (S. aureus) caused skin surface infections. The active ingredients in soap dosage forms of Terminalia catappa L extract have antibacterial properties and retain alkaline properties. The study evaluated Terminalia catappa L extract's quality in a transparent soap formulation in inhibiting S. aureus and maintaining soap organoleptic. Terminalia catappa L was extracted by the maceration method also phytochemical screening. An organoleptic assay examined soap's formulation, and an inhibitory of S. aureus was analyzed by disk method. The ethanol extract of Terminalia catappa L contains alkaloids, saponins, tannins, polyphenols, quinones, flavonoids, and triterpenoids. The transparent soap formulation with the addition of ethanol extract of Terminalia catappa L has good organoleptic properties according to the Indonesian National Standard (SNI) 3532-2016. Also, there is a change in the color of transparent solid soap based on the concentration, at a concentration of 1% (light brown and transparent), 2% (dark brown and transparent), and 3% (dark brown and transparent). Soap with ethanol extract content of Terminalia catappa L has high inhibition of S. aureus at a concentration of 3% (20.09 mm). While the concentration is 1% (13.33mm), 2% (15.58 mm), and soap base (19.36 mm). The transparent solid soap base added with ethanol extract of Terminalia catappa L has good quality, maintains the organoleptic properties of soap, and can inhibit the development of S. aureus.
