COSMETIC FORMULATIONS CONTAINING BLUEBERRY EXTRACTS (VACCINIUM MYRTILLUS L.)

Abstract

The blueberry is a fruit originally native to North America. Consumption has increased globally, mainly due to its reputation for boosting health and longevity. Currently, the cosmetic products market is focused on formulations containing substances with antioxidant activity. The biological properties of the blueberry have already been linked to their polyphenolic content. The aim of this study was to develop and evaluate cosmetic formulations containing Brazilian freeze-dried blueberry extract. Extracts of ripe blueberry fruits were optimized varying the parameters time of extraction and heat, and temperature. The extract with higher polyphenolic content was lyophilised and added to a non-ionic cream in concentrations of 4% and 8%. Rheological behaviour, pH, spreadability, sensorial characteristics and free antiradical activity were tested. Preliminary results suggest that the formulation developed has potential as an antioxidant cosmetic product, though more analysis will be required before the product can go to market
