Herbal cosmetics are defined as products that have been prepared or included in plants and/or herbal components, which are
combinations of many molecules or natural compounds. In this context, the critical parameters that affect the final quality and
stability of herbal cosmetic products are the active principles, the formulation and the manufacturing process. Plant-based
products used in cosmetics include vegetal oils and other lipids, essential oils used as perfumes or for their antimicrobial
activities, skin and hair care ingredients, and antioxidants. The multiplicity of sources of cosmetic ingredients for plants
presents many different ethical and scientific aspects that have not been previously considered or underestimated, such as
resource regeneration, biodiversity conservation, improved isolation and extraction techniques, safety assessment of new raw
materials and the development of innovative formulations. The study presents the physico-chemical characterization
(organoleptic characteristics, refractive index, relative density, acidity index, peroxide index, fatty acids content) and
microbiological evaluation of the fatty oils of vegetable origin obtained by cold pressing of Cannabis sativa L. seeds, as well
as from the fruits of Olea europaea L.
