Product viscosity is one of the important factors affecting consumer purchasing decisions. Consumers often associate the high viscosity of a product with a rich composition Therefore, the problem of viscosity of cosmetic products was discussed in this paper. Aim. The aim of the study was to determine the influence of popular thickeners, mainly used in the food industry, on the viscosity of the standard hair shampoo. Material and method. As a research material, was used the prepared standard shampoo which included: water, sodium laureth sulfates, cocamide DEA, cocamidopropyl betaine, glycerin and analyzed thickener. The authors measured a viscosity of standard shampoo with various amounts of sodium chloride and then compared the obtained results with the values obtained for shampoo which include guar gum, carboxymethyl cellulose or gelatin. Results. The results indicated that change in product viscosity is made at different concentrations of thickeners examined. It was also shown that guar gum, gelatin and KMC are suitable as viscosity modifier, such as salt, in systems containing surfactants. Key words: thickeners, shampoo, guar gum, carboxymethyl cellulose, gelatin |
