    Polyphenols and saponins – properties and application in cosmetics
    (Wydawnictwo Politechniki Łódzkiej, 2023) Mietlińska, Katarzyna
    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.

    Polish plants as raw materials for cosmetic purposes
    (Wydawnictwo Politechniki Łódzkiej, 2019) Mietlińska, Katarzyna; Przybyt, Małgorzata; Kalemba, Danuta
    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 resu lts were obtained for S. canadensis and S. gigantea, than S. virgaurea.
