Analysis of substances potentially dangerous to humans found in lipsticks
Horáková, Kristýna ; Kučerová, Simona (referee) ; Diviš, Pavel (advisor)
The diploma thesis deals with the determination of the content of risk elements and parabens in lipsticks and the assessment of possible negative effects on human health associated with the use of lipsticks. Parabens were analyzed by high performance liquid chromatography with diode array detection (HPLC-DAD). Aluminum, cadmium and lead were analyzed on an inductively coupled plasma mass spectrometer (ICP-MS). The mercury content was determined using an atomic absorption spectrometer with an UV detector (AAS-UV). A total of 36 lipstick samples from 22 cosmetic brands were selected for analysis, with a savings price in the range of CZK 50–1500. Based on the measured metal concentrations, the hazard quotients (HQ) for individual metals as well as the total hazard index (HI) for the sum of all metals were calculated. Metal concentrations in lipsticks were further processed using Kruskall-Wallis Anova to divide samples according to price categories. The relationship between the content of individual metals and the purchase price has not been proven. Furthermore, a Kolmogór-Smirnov test was performed on these data to compare groups with vegan and not vegan composition. The content of aluminum, which was about 2.5 times lower in vegan cosmetics, proved to be statistically significant for this distribution. Parabens were detected in the minimum number of lipsticks examined, but in some cases information on the content of parabens was missing on the product packaging.

Zamrazilová, Linda
ZAMRAZILOVÁ, Linda. Using short-form videos to promote decorative cosmetics to Generation Z. Brno, 2023. Bachelor Thesis. Mendel University in Brno. Thesis supervisor Ing. Stanislav Mokrý, Ph.D. Digital marketing is an important aspect for an effective branding strategy currently. One of the important tools of e-marketing are short videos, also can be called "Short-form videos", which are no longer than 1 minute long and are designed to engage quickly. There are plenty of platforms that provide the service to watch and upload short videos such as Instagram, YouTube and TikTok. The world of decorative cosmetics is just as fast paced as that of digital marketing, with trends changing almost daily, so short videos are the perfect tool to promote it. This paper explores and proposes innovative marketing strategies for the beauty industry in the digital environment, with a focus on the specifics of Generation Z's behaviour. Concrete proposals are presented for Notino, an online cosmetics and perfume e-shop operating in Europe. The aim is to provide a new perspective on the use of digital media and influencer marketing within the beauty industry and to inspire effective online marketing strategies.

Awareness of the public of dangerous substances in cosmetic
NĚMCOVÁ, Kateřina
The title of my diploma thesis is "Awareness of the public of dangerous substances in cosmetic". It is divided into two parts - theoretical and practical. In the theoretical part, I focused on the history, general composition of cosmetic products and dangerous substances it contains. Considering the current trends of society I focused especially on decorative cosmetics. Because I have a negative experience with sunscreens, I concentrated on that issue in the last chapter of the theoretical part. The practical part is focused on the public's knowledge of dangerous substances in cosmetic products. The anonymous questionnaire was educative, because I assumed that many respondents would not inspect components contained in their cosmetic products. I made brief descriptions of the dangerous substances so respondents could get the most important information on this issue.
