The maintaining the proper hygiene of the whole body skin is one of the main purposes of the personal care products. The cleanliness of hands can be treated as the measure of personal hygiene. Personal care products available in the market can fulfil this goal. However modern cosmetic products are supposed to be multifunctional and exhibit not only basic properties. Due to the fact that modern cosmetics contain a large number of components, the quality of the final product is determined by the quality and properties that exhibit single raw material. Multicomponent composition of the product suggests both the synergistic and antagonistic interaction of ingredients included. Therefore without experimental assay it is hard to evaluate the properties of final product. Aim. The main aim of this work was to determine the antimicrobial and surface properties of liquids composed on the basis of surfactants and plants extracts. Results. Results obtained indicate that composition of the liquids presented strongly effects the antimicrobial properties. However the influence of the plant extract is not so magnificent. Key words: liquids, antimicrobial activity |
