Abstract

The aim of the study was to employ BET, GAB, and Peleg models for mathematical description of sorptive properties of market powder shampoos of natural origin. Two commercial powder shampoos of plant origin Sapindus mukorossi (A) and Acacia concinna (B) were used as study materials. The sorption isotherm of A. concinna powder shampoo was much higher in the standard reference system in comparison to S. mukorossi shampoo. The B shampoo had a higher monolayer capacity than product A. The examined process in both cases was physical in nature. The most useful for isothermal description turned out to be the theoretical BET equation and empirical Peleg model. They were characterized by high accuracy. Natural powder shampoos differed significantly in terms of physical parameters of particles and sorptive properties, which may suggest their different functional properties.
