Use of technical hemp extracts in hair cosmetics
Benková, Sarah ; Holub, Jiří (referee) ; Márová, Ivana (advisor)
Technical hemp as a versatile plant has found applications in many sectors of the industry. In cosmetics, it is mainly used for bioactive substances as well as proteins. The subject of this bachelor thesis was the preparation and characterization of a fraction containing hydrolysed hemp proteins and its use in hair cosmetics. In the theoretical part, the characteristics of the plant as well as its chemical composition are processed. Attention is paid especially to hemp proteins, their hydrolysis possibilities, and the subsequent use of hydrolysates in hair cosmetics. Within the experimental part, the preparation of hemp protein hydrolysates from hempseed cake of the Santhica 70 variety was optimized using the industrial enzymes TS-E 1930 and TS-E 1993 and the subsequent determination of the protein content and profile of prepared hydrolysates. The carbohydrate, chlorophyll, phenolic and flavonoid content of the analysed hydrolysates was also determined. A hair conditioner was prepared from the selected hydrolysate and tested by ten respondents. Thanks to the prepared conditioner, hair cosmetics with the addition of hydrolysed hemp proteins has been shown to enhance shine and pliability of the hair, as well as help the healing of frayed ends.
