Abstract

This study was conducted to produce and evaluate the physico-chemical properties and sensory attributes of herbal soap containing Jatropha podagrica roots, Solanum lycopersicum skin, and Pandanus amaryllifolius leaves. Plant materials used are locally found, grown, and harvested in Baco, Oriental Mindoro, Philippines. Crude extracts were acquired using ethanolic extraction from which three various concentrations (%v/v) were derived to proceed in herbal soap making. Herbal soap underwent testing for physico-chemical properties such as foaming propensity test, pH profiling, and emolliency test. Sensory profiling test using modified quantitative descriptive analysis was also administered. Foaming propensity test of three soap formulations showed that the soap with equal concentrations of J. podagrica, S. lycopersicum, and P. amaryllifolius (1.0671 % v/v) ethanolic extracts exhibits the strongest foam stability due to the combined viscosity of the three ethanolic extracts. The three treatments (T1, T2, T3) demonstrated mild, moderate, and strong translucency respectively under the soap emolliency test showing that other than oil content, varying concentrations of the ethanolic extracts affected the emolliency property of the soap. Quantitative Descriptive Analysis (QDA) of the sensory attributes of the three soap formulations showed that difference exists between all the formulations in terms of color (p = 0.00757) and texture (p = 0.03278). No difference was observed for odor and lathering intensity attributes. Treatment 2 exhibited best result in foaming propensity test. All treatments demonstrated normal soap pH level. Meanwhile, Treatment 3 showed positive results in quantitative descriptive analysis. Further studies and laboratory tests like antimicrobial test were recommended.
