Abstract

The objective of this research was to develop glycerin soap products, mulberry leaf tea extract and mulberry leaf tea extract mixed with turmeric soaps, containing herbs of Lopburi province. The physical and other chemical properties of soaps, antioxidant activity tested using DPPH method, and antibacterial activity were studied. Six soap formulations, each of which contained 25 g glycerin soap base, were compared. Three soaps contained varied amount of 10 g/100 mL mulberry tea extract while the others were turmeric powder soap, mulberry tea extract and turmeric powder soap, and the non-herbal soap (control).  From the results of the experiment, it was found that the soap had no foreign matter.  The color values expressed as L*, a* and b* of the soaps containing mulberry extract were 14.07 ± 1.44 to 19.47 ± 0.14, -0.05 ± 0.14 to 0.80 ± 0.12, and 2.13 ± 0.08 to 3.25 ± 0.40, respectively, while those values of the soap containing turmeric powder were 20.06 ± 1.01, 4.98 ± 0.29, and 6.52 ± 0.26, respectively.  The properties of all soaps; pH (9.36 – 9.83), bubble volume (66.33 to 76.67 mL), durability of the bubble (62.33 - 70.67 mL), and erosion percentage (23.09 ± 2.15 to 25.08 ± 1.23 %), were evaluated.  The antioxidant activity values of the soaps were in the range of 18.38 ± 0.93 to 53.36 ± 0.39 %, and also expressed as 1.25 ± 0.01 to 3.45 ± 0.11 ascorbic acid equivalents (AAE)/g soap. The herbal-containing soaps had higher antioxidant activity than the non-herbal soap. The soap could inhibit gram-positive bacteria; Bacillus cereus and Staphylococcus aureus.
