The made products using natural actives have reached a great development in the modernity of the human being, besides having a great interest in the industry due to the replacement of chemical substances with natural extracts that makes a product with sought features inside a new market trend as natural cosmetics. The present work determined the stability of four cosmetic formulations made from natural actives of: Matico (Aristeguietia glutinosa) and Ishpingo (Ocotea quixos) used at different concentrations. The behavior of the formulations, packaged in glass and plastic, in two storage conditions (ambient conditions and controlled conditions at 45ºC - 75% of Relative Humidity) were studied monthly for three months, allowing to evaluate parameters such as: pH, viscosity, organoleptic characteristics, microbial count and the total phenols concentration, chemical characteristic related to the cosmetic effect given to the formulations (antioxidant activity) concentration variation used to determine the useful life of the creams using the Poppe method. The results of the study were analyzed by ANOVA in conjunction with the Duncan test at 5%, the analysis showed that creams stored under environmental conditions maintained physical and chemical characteristics, while those at 45 ° C and 75% RH did not retain their characteristics in the time. In the phenol concentration, the formulations with combinations of the essential oils were kept for a longer time, showing a significant difference in one of the four formulations tested. Using the Poppe method, a useful life of less than two years is determined for all formulations. |
