Analytical Characterisation of Original Emulsion for Cosmetic Use

The aim of the paper is to characterize an original emulsion containing a mixture of plant macerates and essences. Next the wild and/or garden plants, namely Abies sp. (leaves), Crataegus monogyna (flowers), Hypericum perforatum (flowers), Lavandula angustifolia (flowers), Lavandula officinalis (flowers), Lilium sp. (flowers), Melissa officinalis (flowers), Mentha silvestris (leaves and flowers), Mentha piperita (leaves and flowers), Origanum vulgare (leaf blooms and flowers), Pinus silvestris (buds), Populus nigra (buds) and Thymus serpillum (flowers) have been processed to prepare the studied emulsion. Some of the emulsion ingredients as the essential oils of single plant and plant mixture, or the lily flowers macerate together with the final product have been analyzed. The measurements of physical and chemical properties (refractive index, density, pH, oxidation-reduction potential, acidity index, peroxide index and iodine index) led to interesting results that could explain the curative effects on skin. The beneficial effects of new emulsion are due to the bioactive compounds that penetrate deep into the tissue and ensure regeneration. The obtained results confirm our previous findings concerning the opportunity of measurements of oxidation/reduction potentials for cosmetic mixtures regarding the antioxidant activity description.
