Course detail

Technology of biopolymers and natural raw materials processing

FCH-MC_BPSAcad. year: 2021/2022

Due to global changes, waste problems accumulating in nature and cities, the occurrence of higher sensitivity and emerging allergies to different products increases the demand for "organic" products in various applications, including cosmetics, pharmacy, medicine and packaging materials. This course responds to this new trend towards the realization of the future with a sustainable economy and environment, but also the health of individuals and society. Biopolymers, their origin, properties and applicability for the preparation of cosmetics as well as the types of packaging of cosmetics will be discussed. The composition, preparation, testing and labelling of individual types of cosmetics will be discussed also. Furthermore, this course will address the possibilities of using biopolymers in medicine and pharmacy. The stability and "bio" degradation of biopolymers and formulations containing them will also be considered. Finally, perspectives for the wider use of biopolymers and natural substances will be summarized.

Aims

The course aims to provide students with an overview of biopolymers, their structure, properties, technologies of their isolation, and possibilities of use in cosmetics. The first section will focus on the properties and isolations of biopolymers; the second section will focus on cosmetic products containing biopolymers, their composition, preparation techniques, and quality testing. The third section will focus on the characterization, use, and stability of packaging materials for cosmetics based on biopolymers.
