PRODUCTION OF HIGH QUALITY SOLID ORGANIC SOAP FROM BLENDED VEGETABLE OIL
Abstract
ABSTRACT
The study investigated the production of high-quality solid organic soap using blended vegetable oils with the aim of optimizing physicochemical and sensory properties. The research employed an experimental laboratory-based design, utilizing coconut, palm, olive, and shea butter oils in various ratios. Soap was produced using the cold process method and evaluated for physical properties (hardness, lathering ability, color, and texture), chemical properties (pH, moisture content, saponification value), and sensory attributes (fragrance and overall acceptability). Results showed that the soap formulation S1 (40% coconut, 30% palm, 20% olive, 10% shea butter) exhibited optimal hardness, highest lather volume, stable pH, and low moisture content, making it safe and suitable for skin use. Sensory evaluation by panelists indicated that S1 was most preferred in terms of color, texture, fragrance, and overall acceptability, outperforming other formulations and matching the quality of commercial soap. The study concluded that blending vegetable oils enhances soap quality, offering a viable alternative to chemically-laden commercial soaps and providing a framework for small-scale production of organic soap using locally available materials.
