Elaboración y evaluación de una formulación de shampoo obtenido a partir del mojuelo de quinua (Chenopodium quinoa)

Abstract

The objective of this study was to develop and evaluate a shampoo formulation obtained from quinoa mojuelo (Chenopodium quinoa). Saponin was extracted using the wet saponification process and then with solvent evaporation. Using simple formulas, the optimal concentration of saponin and the affinity and interaction with rheological agents of celluloses and salt were determined, obtaining concentrations of 2% in celluloses and 1% in salt. With the established values, seven treatments were elaborated with different formulations subjected to a preliminary stability study. The test period was six cycles and each cycle of 48 hours, which consisted of maintaining the samples under stress conditions with temperature changes every 24 hours from hot (45ºC ± 2ºC) to cold (5ºC ± 2ºC), at the end of the cycle, physicochemical tests were carried out. The final product was selected by analysing the trajectory during the cycles, treatment C was the most stable even when the viscosity decreased by 32%, maintaining similar values to the room temperature sample, continuing within the viscosity and pH ranges; Regarding the foaming capacity, the height level among their samples was from 8.5 to 9.0 cm with no apparent decrease, on the other hand, in the organoleptic tests at the end of the period there were no physical or chemical incompatibilities. Microbiological tests were determined on the final product, these were acceptable according to the requirements of the NTE INEN-2867 standard. As the last control, the irritability test was applied to a group of people, in which no adverse skin effect was observed.
