FORMULATION AND STABILITY EVALUATION OF BAUHINIA VARIEGATA EXTRACT TOPICAL EMULSION
Abstract:
This study presents the results for the development of water in oil (W/O) emulsion containing 2 % Bauhinia variegata (BV) extract with good antioxidant potential for cosmetic application. Different ratios of surfactant, oil and water were investigated to optimize the ratio of ingredients. It was found that emulsifier and oil4ratio were important in improving the stability of emulsion. The formulation having 2.5% Abil EM90, 12% liquid paraffin, 83.5% distilled water and 2% BV extract was found to be most stable. Stability of the formulation was further evaluated by characterizing for organoleptic, sedimentation, microscopic and rheological properties at a range of storage conditions for a period of 12 weeks. Experimental findings showed stable formulation behavior with respect to color change, liquefaction and phase separation. Centrifugation test was carried out to predict the long term stability..The rheological parameters were evaluated from Power Law and the flow index value less than 1 suggested non-Newtonian behavior of the W/O emulsion. The mean droplet size of the internal phase of freshly prepared formulation was 4.06 ? 1.99 pm that did not change significantly (p > 0.05) during the storage. The newly developed formulation exhibited promising attributes over long term storage and open opportunities for the topical delivery of natural antioxidants for cosmetic and pharmaceutical objectives.
