Production of Water and Oil Based Paints Using Hydrosol Obtained from Locally Sourced Materials

Water based paint (emulsion, screeding, matt paint) and oil paint (gloss paint) were produced using hydrosol formulated locally by adopting steam method. The raw materials were hibiscus flowers, mint leaves, rosemary and lemon grass. Soxhlet extractor was used to hydrosol from the crushed leaves using normal-hexane as solvent. Distillation process was carried out to separate the hydrosol from the solvent in the hydrosol-solvent mixture, obtained from the extraction process. The hydrosol was characterized to determine the physiochemical properties and hence its suitability for paint production. The results showed the physicochemical parameters of the produced hydrosol were within the standard values, of Refractive index = 1.3698, pH = 6.5533, conductivity = 0.5167us/cm, TDS = 78.1667mg/l, density = 0.5183g/cc, specific gravity = 0.5183, viscosity = 8.1083cst, boiling point = 74.70C. The produced hydrosol was used in the production of emulsion, screeding, matt and gloss paints which were characterized and they gave the following physicochemical results of pH = 6.90, 6.94,7.39& 6.62. Specific gravity = 23.75, 23.75, 23.75 & 23.75. density = 1.4078g/cc, 1.2396g/cc, 1.136g/cc, & 1.1164g/cc. viscosity = 9.8cst, 10.5cst, 10.8cst and 8.47cst. drying time= 6hrs, 6hrs, 4hrs & 6hrs. Temperature = 280C, 28
