title: Influence of the concentrations of liposomes and a submicron emulsion on the rheological properties of a topical gel.
abstract: Two different kinds of liposomes and a submicron emulsion were added to a topical hydrogel consisting of alginates. The rheological characteristics of the gels after various dilutions were investigated. The various preparations studied exhibited a similar rheological behaviour. No important interactions were observed by mixing the hydrogel with liposomes or a submicron emulsion. The viscoelastic properties and gel state were preserved, only a decrease in consistency was measured.
