Effects of Blend Composition on the Rheological Properties of Xanthan/locust Bean Gum Blend in Emulsion
Synergistic polysaccharide-polysaccharide interactions are attractive commercially and enjoy widespread technological exploitation (Cairns et al., 1987). Expensive polymers may be replaced by a cheaper mixture. Xanthan/LBG solution was prepared by adding the gum into hot water and further heating to 80℃ for about 30 min with continuous stirring to ensure complete solubility and to obtain a clear homogenous solution. The storage modulus(G' ) and the yield stress of solutions were increased with increasing LBG ratio, which was mostly noticed between LBG ratio 0.5∼0.75. On the other hand shear thinning effect was shows at high shear on LBG ratio 0.25. Elastic modulus was increased with increasing LBG more than two times and it was enhancing suspending properties on emulsion. Since the rheological properties describe the fundamental information about the cosmetic, these results may be of help to the design of new feeling cosmetic emulsion.
