Rheology & tensile strength of nanoemulsion hydrogel vs macroemulsion hydrogel / Rohayu Ibrahim

An emulsion is a system consisting of two immiscible liquid phase, one which is dispersed through-out the other in the form of fine droplets by the help of emulsifier. Emulsion hydrogel is the semisolid formed from incorporation of emulsion and Carbopol hydrogel. In this study, physical characterist...
