【 摘 要 】

There is a growing awareness of medicinal benefits of renewable forest resources that can be used as natural cosmetics for the benefits of human skin health. Today, more rural dwellers in forest reservation have resorted into utilizing more Non-Timber Forest Products (NTFPs) and agro-processing wastes products (APWPs) into African Black Soap (ABS) otherwise called Herbal Soap (HS). Some of the NTFPs that fall under natural cosmetics are herbal soap (black soap) produced from Cocoa Pod Husks (CPH); Shea-butter; Coconut Oil; Aloe-Vera Gel, and Natural Fragrance Oil. This is an excellent natural body-care soap in the original fashion and suitable for all skin types. The major raw materials that are used to produce herbal soap are from NTFPs and APWPs such as CPH; Palm Kernel Oil (PKO); cassava peels (CP) and, Plantain Peels (PP). 5g weight of each sample was dissolved in 50ml of solution (10% Concentration) to get the results. The results of the physico-chemical analysis (PCA) on Herbal soap and photographic impressions of ten (10) samples collected during field survey from different locations in South western, Nigeria revealed the following: The pH range of the herbal soaps (10% solution) is between 9.89 to 10.18 which is a good indication that the herbal soaps fall in the mid alkaline pH range - (that is, ideal soap pH range that have little or no irritation on mildest skin texture. Some synthetic soap that bleaches gives a pH range above 10.50 and other acidic soap below 6.98. pH range of the soap (10%) lies between (981-3110) x 10 mg/L which is a good indication. The Total Dissolved Solid (TDS) mg/L of the herbal soaps falls between 981-3110 mg/L which is a good indication of inertness of the soap to atmosphere when expose to moisture. Industrial PKO (981-1775) melted but traditional processed PKO (1800 -3110) stayed dried. The Conductivity (US/cm) of the herbal soaps ranges from 18,200-47,150 (US/cm)x10. This measured parameter indicates the extents of dissolved ions present in the herbal soap materials that when releases nourishes the skin on use. The higher the dissolved ions, the better for skin absorption of the desirable ions which result into healthy skin in human being.
