Influence of particle size of cosmetic pigments on final properties product
Obručová, Kateřina ; Hurčíková, Andrea (referee) ; Zemanová, Jana (advisor)
This diploma thesis is focused on the study of the influence of the of size cosmetics pigments on the properties of the final product. This effect was studied on samples of make-up given by industry partner. Make-up samples were measured by the rheology method and the yield stress of all samples was determined. Scanning electron microscopy was used to determine the size and shape of the pigment particles. Particle size was also measured by dynamic light scattering, but the results were influenced by forming aggregates. To easier determination of the types of pigments in the sample was determined elemental composition of the pigments (Ti, Fe, O, Al) by EDS detector. Due to the unknown composition of make-up, the information was supplemented by X-ray powder diffraction (XRD) analysis, and it was possible to determine the compounds TiO2 (anatase and rutile), FeOOH and Fe2O3. The results obtained by these methods showed what pigments can be found in make-up samples, what their sizes and shapes are. It has been shown that the smaller the pigments are, the higher the viscosity and yield stress of the final product. The higher these quantities, the harder it is to handle the product.

Study of particles of various cosmetic pigments
Cerevatova, Kristina ; Opravil, Tomáš (referee) ; Zemanová, Jana (advisor)
The main focus areas of this master thesis include the writing of a literature review, which contains an overview and segregation of pigments which are used in the preparation of cosmetic products. The thesis is focused on the properties and characterization of pigments for use in cosmetology. The following focus is on legislation, more specifically on pigments that the cosmetic industry allows, limits and does not allow. The main part of this thesis is an overview of methods for the characterization of pigments. The practical part deals with the characterization of particles of selected cosmetic pigments by applying methods for determination of color, elemental and phase composition, particle size and morphology. The thesis is concluded by evaluation of the achieved results.

Bussiness Plan
Zajacová, Lea ; Luňáček, Jiří (referee) ; Hanušová, Helena (advisor)
The aim of this Bachelor’s thesis is to develop a business plan for establishing a salon with permanent eyebrow make-up. It’s divided into three parts; the first part focuses on the theoretical elaboration of methods needed for the issue. The second part is focused on the practical side of the mentioned methods and the last part deals with the practical design of a business plan.

Everyday fashion show
Rémanová, Jana ; Šagát, Petr (referee) ; Ruller, Tomáš (advisor)
Work is dealing with the problems of unusual clothing and conflict with surroundings. The work includes research of what is regarded as weird, extravagant and alternative in everyday fashion, but also designs of outfits inspired by research made by questionnaires and finally realization of artistic performances in public places. The result of the project is information obtained from the research of one hundred respondents. Furthermore, a series of ten "costumes", which show the stimuli obtained from previous research from selected questionnaires. Each model is an example of the stereotype of what was found to be eccentric in dress. In these models, a performance was subsequently performed in public. All individual phases of project creation are presented as a whole and presented as a bachelor's thesis.

Vliv influencer marketingu na chování spotřebitele na trhu s dekorativní kosmetikou
Hausknechtová, Tereza
Hausknechtová, T. The impact of influencer marketing on consumer behaviour in the decorative cosmetics market. Bachelor thesis. Brno: Mendel University in Brno, 2023. This bachelor thesis examines the impact of influencer marketing on the consumer behaviour of women aged 15 – 26 in the decorative cosmetics market. The study identifies the influences on consumer purchasing decision making processes related to influencers and social media. Primary research findings were used to formulate recommendations for the successful use of influencer marketing as part of marketing strategy.
