Liquid Cleansing Product Ranking In Order Of Human Perceived Change In Rheological Properties

Abstract: An instrument-based method for ranking at least two liquid cleansing products in order of human perceived change in at least one rheological property at predefined conditions. The instrument-based method comprising obtaining the at least two liquid cleansing products; measuring viscosities of each of the at least two liquid cleansing products at the predefined conditions, wherein the predefined conditions comprise one varying  environmental parameter; determining sensitivity of viscosity to the varying environmental parameter based on the measured viscosities; and ranking the at least two liquid cleansing products as per the sensitivity. The ranking of the at least two liquid cleansing products replicates an order of a human perceived change score (∆) of the at least one rheological property over the predefined conditions as is obtainable from a panelist evaluation.
