Three body lotions (water-in-oil type) differing only in the emulsifier content were subjected to rheological measurements and sensory analysis with the aim to obtain coupling between the selected rheological characteristics and sensory factors. Both methods proved different behaviour of the samples caused by the difference in the emulsifying compound. To detect the relations between rheological (application of the power law model) and sensory variables, the four most important characteristics from sensory assessment (ease of pouring from the bottle, ease of spreading on a palm, thickness, and ease of spreading on back of hand) were selected. A close coupling (and hence mutual substitution) was found between consistency parameterkand thickness,kand the ease of pouring from the bottle, and alsokand the mean droplet size.
It was shown that a description of chosen sensory attributes can be responsibly carried out by rheological measurements, that is through the attained numerical values of the parameters appearing in a proposed empirical model characterizing shear viscosity of body lotions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
