Increasing the Antioxidant Activity of Liquid Soap with a Combination of Carrot Peel Extract (Daucus carota L) and VCO (Virgin Coconut Oil)

Bath soap is a skin cleansing preparation made from the saponification or neutralization process of fat, oil, wax, rosin, or acid with an organic or inorganic base that does not irritate the skin. Skin rashes can be treated with antioxidant compounds. This can be observed from the antioxidant compounds, such as the carotenoid compound, and the bromelain enzyme found in carrots (Daucus carota L) and pineapple (Ananas comosus). The combination of these two plants is believed to produce maximum antioxidant activity. This research aims to assess the possibility for increasing the ability of antioxidant activity in liquid soap preparations combining VCO carrot extract from pineapple fruit by creating several series of liquid soap formulas with carrot peel extract combined with VCO. The preparation was then evaluated and antioxidant activity was tested using DPPH. Subsequently, data analysis was conducted using SPSS with the Kruskal-Wallis method. Given the findings, the best formula is Formula 3, which had an IC50 value of 4.11 ppm and very significant antioxidant activity.
