The current trend in cosmetics is to offer natural and organic cosmetics that are friendly to the environment. The cosmetics industry should respond to this demand by developing raw materials to be accordance with this new preference, within these, the remarkable use of preservatives, whose main function is to prevent microbial contamination of products during manufacture, storage and use.
The study evaluates the effectiveness of essential oil of Curcuma longa as an organic preservative in cosmetic formulation. Five formulations are made, in which varies mainly the concentration of essential oil. Preservative efficacy is tested by testing for the evaluation of antimicrobial preservation in cosmetic products (Challenge Test), according to the international standard ISO 11930: 2012.
The results conclude that the formulation with 2.5% concentration of essential oil of Curcuma longa is effective as a preservative for organic and natural cosmetics, because it meets the acceptance criteria A of the international standar ISO 11930:2012. This result is reconfirmed by using the Tukey Test, which also leads to the conclusion that it is a broad spectrum preservative, against microorganisms used. |
