Desenvolvimento e estudo de estabilidade preliminar e acelerada de fitocosmético capilar contendo óleo de Carapa guianesis Aubl. e manteiga de Astrocaryum murumuru Mart.

Abstract

To develop hair phytocosmetics based on oil from Carapa guianesis Aubl. and butter from Astrocaryum murumuru Mart. and to carry out the preliminary and accelerated stability study. Shampoo and conditioner formulations were prepared containing between 0.5 and 1.5% of andiroba oil and murumuru but ter, respectively. In the preliminary stability study, 06 freeze/thaw cycles were performed for 12 days, the accelerated study for 90 days. The samples were stored at 25 ± 2 °C and 45 ± 2 °C, and the parameters analyzed were: organoleptic characteristics, pH and viscosity. All analyzes were performed in triplicates. During the preliminary stability study, the formulations kept at 25°C showed no changes in color, appearance and the odor became less intense. The samples from the freeze/defrost cycle, the sham poo showed changes in color, appearance and odor. Samples at 45°C from the fifteenth day onwards showed variation in color and consecutive increase in viscosity until the end of the test. The conditioners at 45°C from the fifteenth day showed variation in odor and viscosity, after the sixtieth day the samples at 25°C and 45°C showed changes in color. As for the pH and viscosity, the results of the analytical test showed significant differences between the samples at 25°C and the samples kept at 45°C. Given this, changes in the organoleptic parameters, pH and viscosity at elevated which may affect the stability and efficacy of the product, however, this work demonstrated that the incorporation of vegetable oils and butters such as andiroba oil and de murumuru butter are compatible with the excipients in the formulation of hair phytocosmetics.
