| Abstract: | The aim of this study was to evaluate the antimicrobial activity of selected essential oils ( Laurus nobilis , Eucalyptus globulus and Salvia officinalis ), both alone and in combination, in cosmetic preparations characterized by an increasing risk of microbial contamination, i.e. an O/W skin cream, a hydrogel and a non-alcoholic hydrolyte. Their potential synergistic effect in combination with the usual cosmetic preservatives at low concentrations (up to 200-fold less than usual) was also investigated. |
