Utilization of bees products in cosmetics
Kobza, Martin ; Bednář, Michal (referee) ; Zemanová, Jana (advisor)
This bachelor thesis is focused on the problem of utilization of bees products in cosmetics. The aim of this thesis was to elaborate a literature review focused on individual bee products, their properties and their utilization in cosmetics. Honey, beeswax, propolis, pollen, royal jelly, apisin are said to be the bee products. Properties, utilization, determination of kvalitative properties and aplication into cosmetic products of individual bee products are mentioned in this thesis. Beeswax is used in production of lipsticks, creams and for basis of smears (oily creams). Royal jelly is aplicated into lotions, face masks, lipsticks, night creams, hair waters, hydration preparations etc. Honey is used for preparation of shower gels, soaps, body milks, hydration creams. Propolis is added into creams, body milks, body lotions, shampoos, lipsticks, soaps and mouth sprays. Pollen has significant content of vitamins, aminoacids and other substances in nature form for cosmetics. These substances are important for nutrition, regeneration and hydration of skin. Apisin is used in pharmacologic preparations, like healing creams and smears.

Optimization of preparation and characterization of hybrid hydrogels with respect to viscoelastic and flow properties
Zhurauliova, Darya ; Kalina, Michal (referee) ; Smilek, Jiří (advisor)
This bachelor thesis focuses on the study of hybrid hydrogels that combine the properties of the hydrogel system together with oleogels, which is a gel on the base of oil. The aim of the thesis is to carry out a study of the current state of the solved issue on the topic of preparation of hybrid hydrogels, on this basis to design and optimize the appropriate procedure of preparation and in the form of viscoelastic measurements to perform the basic reological characterization of the prepared systems. A system based on sodium alginate dissolved in deionized water and meshed with calcium chloride solution was chosen as a suitable hydrogel system, and a system based on beeswax dissolved in sunflower oil was chosen as oleogel. Sodium alginate has been chosen because it is used as a thickener, emulsifier, stabilizer or gelling agent in the creams and preparation of pharmaceutical forms. By mixing hydrogels and oleogels of different proportions, a hydrogel/oleogel system, also called bigel, was created, the properties of which were tested in terms of flow and viscoelastic properties. In the practical part, amplitude, frequency and flow tests of both the hydrogel itself and the hybrid hydrogel with a ratio of 50:50 (hydrogel vs. oleogel) were measured. These tests provided information on gel preparations, i.e. what is their character, what are the mechanical properties and how it depends on the amplitude of deformation. By comparing the measurement results, it was possible to determine how oleogel acts on the properties and structure of the hydrogel.

Voskové směsi pro restaurování historických voskových pečetí
Bílková, Lenka ; Bartl, Benjamin ; Urbánek, Štěpán ; Zapletal, Martin ; Holakovská, Libuše
A large number of historic wax seals have been preserved in a fragmented state, which is linked to the increase in hardness and brittleness that sealing waxes undergo during natural ageing. The immediate cause of mechanical damage is careless handling or improper storage of archival records. This methodology compares the properties of both traditional and some alternative wax mixtures that are applicable for conservation of damaged seals. The aim is to highlight the advantages and disadvantages of using each of them, making it easier for conservators to choose a material that will meet their specific requirements. Chapter 2 first discusses the general requirements for such materials, from a technological, practical and ethical point of view. Chapter 3 deals with the properties of beeswax and the possibilities of their modification by the addition of other substances. Chapter 4 then discusses the new possibilities that open up the use of fossil wax mixtures. The chapters are supplemented by specific examples and recommendations.

Bee products and possibilities of their use
LUKÁŠKOVÁ, Jana
The target of my Bachelor?s Thesis is to describe the importance of Honey Bee and focus on bee products. With its pollination activity Honey Bee secures propagation of entomophilous plants, is involved in protection of environment and increases yield of arable crops. Honey Bee products have versatile use. Honey is a good quality food supplement. Bees wax and propolis are due to their properties an important material for cosmetic industry. Bee poison is used for hymenoptera allergy care. Pollen serves as an energy source and royal jelly is used for treatment of central nervous system.

Apitherapy and its use in the healthy lifestyle
GIEBLOVÁ, Simona
This Bachelor Thesis deals with creating and verifying educational program ,,Apiterapie? for students of faculties of educational nature. With content analysis of editorial resources, I have established a theoretical part where I try to explain topics in a context of natural alternative techniques as an important source of health promotion. Then I prepared training program focusing on bee products and their use in practice. The practical part verifies the tutorial on the set of students majoring in Health Education Faculty of Education University of South Bohemia in České Budějovice, using input and output test or the deliberate observation. Determining the level of knowledge of students, after completing the training program and obtain their views on the selection of the object Apiterapie. Processed teaching materials are illustrated in PowerPoint format on CD.
