Využití technického konopí do kosmetiky proti akné / Use of technical hemp in acne preparations

Hemp belongs among important plants with a long industrial tradition. However, its first use was originally for healing. In medicine, it is mainly applied thanks to the content of many biologically active substances, such as cannabinoids. This thesis is concerned with the use of hemp in acne preparations. The theory focuses mainly on the characterization of hemp and its active substances. The other chapters deals with cosmetic preparations and acne itself, and Propionibacterium acnes as well, which is involved. Within the experimental part, the extracts of two hemp varieties (Finola and Bialobrzeskie) were characterized in terms of antioxidant and cannabinoid presence. The cosmetic preparations with hemp extract content were prepared including a complete cleansing set for acne skin, concurrently commercial products of this sort were purchased. In cosmetic preparations and the extracts their inhibitory effect against Propionibacterium acnes was studied as well. Also Micrococcus luteus, Escherichia coli and Candida glabrata were tested. The results show that dried hemp flower extracts contain the greatest amount of active substances, so they have a higher antioxidant and antimicrobial effect. The presence of individual cannabinoids differed mainly depending on the variety. All hemp extracts had effect against gram-positive bacteria, in cosmetic preparations it was lower. Nevertheless hemp antibacterial effect has been proven.
