The aim of this work is to briefly present a few data about the preparation methodology and characterization of different series of vegetal essential oil (i.e. mint, lavender, rosemary and thyme)/water (O/W) emulsions based on beeswax matrix, glycerin, emulsifying agent (Tween 80), prepared by varying the essential oil and beeswax concentrations. These O/W emulsions were preliminarily characterized by a few physical-chemical quality indicators (i.e. pH, normalized density, acidity index, peroxide index, content of conjugated dienes and trienes, total content of polyphenols and flavonoids, total fatty acids) as well as the creaming indexand sensory analysis, and also their in-time stability for a time period higher than 8 monthsat room temperature.The most stable O/W emulsions were recommended for use to a Romanian textile materials manufacturer to add value to its textile products, especially due to the potential antibacterial action of impregnatedtextile materials and also well-being effects and skin care benefits. This work underlines also that the most recommendable emulsion must have a relative good in-time stability till the separation of organic and aqueous phases, as well as a satisfactory content of polyphenols and flavonoids, which are mainly responsible of antibacterial activity of impregnated textiles (cotton fabrics) which can be utilized for patches and bandages manufacturing for wellness and human health effects. |
