    Opis:
    The cosmetics market is more and more demanding, and there is a constant request for new products. The aim of the study was to find plant materials occurring commonly in Poland that would have a multidirectional effect on the skin. Research focuses on plants with high content of saponins and polyphenols. Ability to create foam and ability to reduce the surface tension of water as a determinant of saponin content was checked. The Folin-Ciocalteu test was made to check the content of polyphenols. Fifty-seven raw materials were examined. To the most promising for cosmetic purposes belong goldenrods (Solidago), especially their leaves. Much better results were obtained for S. canadensis and S. gigantea, than S. virgaurea.

    Opis:
    Toad skin secretions are a rich source of various biologically active compounds, such as alkaloids, bufadienolides, biogenic amines, or peptides. Also plants from Hyacinthaceae and Crassulaceae can be a potent source of these groups of molecules. These compounds play a crucial role in amphibians’ and plants’ physiology such as defense against predators or pathogenic microorganisms. Among them, bufadienolides are the focus of many researches in recent years. These molecules have a very interesting, steroidal chemical structure and have potent activity at the cellular level. They possess cardiotonic, antiviral, antibacterial, antitumor, anti-inflammatory, hemostatic, bacteriostatic, wound-healing, and antiparasitic properties. Although the structures of about 500 bufadienolides are known, it is strongly suggested that this group of compounds is still very poorly examined. Moreover, bufadienolides may be an excellent basis for the chemical synthesis of new drugs with selective bioactivity. The aim of this paper is to briefly overview bufadienolides as potent compounds for medicines and cosmetics.

    Opis:
    Knowledge of the sun protection factor SPF of a sunscreen product is essential for the safe use of solar radiation. In Poland and in the European Union, in vivo method is used to determine the SPF. This method is time-consuming, expensive, does not ensure repeatability, and raises ethical doubts. Therefore, instrumental methods that can replace the traditional in vivo method are sought. In this study an attempt to determine sun protection parameters, such as SPF, degree of protection against UVA and critical wavelength of selected sun protection cosmetics was made with the use of a simple spectrophotometric method based on measuring the absorbance of ethanol solutions of selected sunscreen cosmetics. The obtained results may be useful for future development of a new in vitro method for determination of sun protection parameters of sunscreen cosmetics.

    Opis:
    The use of thermal waters both for external use and for consumption is presented. Nowadays, the use of ecological products of natural origin is promoted, allowing for a significant improvement in the psycho-physical condition of users. Research is carried out to create natural products that comprehensively improve not only the condition of the skin, but the entire body of the user. Thanks to the development of modern technologies used both in cosmetics and other industries, it is possible to effectively use the composition and properties of thermal waters.

    Opis:
    The cosmetics market is an extremely dynamic, developing branch of the industry. There is a constant need for multifunctional ingredients that will meet the growing expectations of consumers. Active ingredients of natural origin are also appreciated more and more often. One of the most commonly used plant extracts are those rich in polyphenols. These ingredients are known for their antioxidant properties, but they can have many more functions in relation to human skin. They act against wrinkles, brighten skin, support protection against harmful UV rays, etc. Other interesting active plant ingredients are saponins – compounds with an amphiphilic structure – that can be natural alternative to surfactants or emulsifiers. They possess antimicrobial activity and strengthen blood vessels. This article briefly characterizes polyphenols and saponins, taking into account their structure and classification, as well as indicates and describes their properties that can be used in the cosmetics industry.

    Opis:
    Nowadays, men are paying more and more attention to their appearance, and thus try to provide their skin with proper care so that it looks healthy and without signs of aging. In the present study, ashwagandha (Withania somnifera) and moringa oleifera (Moringa oleifera) were selected from the most popular adaptogens used in cosmetics, which are currently not commonly used in cosmetic preparations for men. The selected adaptogens were compared for their phytochemical and antioxidant properties to determine their skin care effects in cosmetics. The phytochemical content was evaluated through the determination of total phenolic content and in vitro antioxidant capacity was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS{2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)} free radical scavenging tests. The total phenolic contents 1.81±0.13 and 0.14±0.02 mg GAE/g extract were found to be present in Moringa oleifera and Withania somnifera glycol-water extracts, respectively. Among the two chosen extracts, Moringa oleifera exhibited significant free radical scavenging activity, ABTS (0.964 ± 0.021 mg TE/g extract) and DPPH (0.822 ± 0.004 mg TE/g extract). It can be concluded that Moringa oleifera extract has strong antioxidant properties than Withania somnifera extract.

    Opis:
    This paper describes the cosmetic market development in Europe and in Poland. This review focuses on the last part of the cosmetics proces production - confection, mostly on the packaging type materials, the function and design as well as the colour and information put on the labels. The packaging of the cosmetics influences the consumers decision concerning the choice and the purchase of the cosmetics. It is an important process which decides directly about the economy of the company.
