External application of seabuckthorn oil (Hippophae rhamnoides L.) is difficult due to its liquid state in spite of its benefits for damaged skin. In order to overcome this inadequacy the semisolid emulsion with seabuckthorn oil was prepared. Previous research showed that this emulsion possessing an enhanced structure with liquid crystals showed a higher wound healing potential than seabuckthorn oil. The aim of this investigation was to characterize suitability of this emulsion for topical use. The emulsion was prepared by combining emulsifiers that form liquid crystals. Two different quantities of seabuckthorn oil were incorporated. Samples were prepared with 10% and 40% of seabuckthorn oil. Organoleptic characteristics were estimated visually and by smearing samples on a thin glass plate. Type of emulsion was determined by a conductometric method, while a pH value of the emulsion was measured by a pH meter. Samples of seabuckthorn emulsion were orange, semisolid, shiny, easily spreadable on skin, and the smear on the glass plate was homogeneous. There was an absence of smell and the emulsion could be rinsed by water after the application on skin, which is a desired characteristic of oil/water emulsions. Results of an electrical conductivity confirmed that an outer phase is water. Samples possesed an acceptable pH value for an external topical use. This research confirmed that constituents and a method used were suitable for preparing semisolid emulsion with seabuckthorn oil. Organoleptic properties, a pH value and a type of obtained emuslion appear to be adequate for topical use.
