The aim of this work was to evaluate the antioxidant capacity and flavonoids content in 10 commercial cosmetic plant extracts used in cosmetics industry. Antioxidant activity of plant extracts were measured using two methods: FRAP (Ferric Reducing Antioxidant Power) and TEAC (Trolox Equivalent Antioxidant Capacity). The relationship between flavonoids content and antioxidant capacity of plant extracts were checked. As a result of this research it was found that FRAP and TEAC values of plant extracts significantly depend on the flavonoids content. The highest antioxidant activity, both in FRAP and TEAC assays, was observed for arnica flowers, hawthorn flowers and lungwort herb extracts. These extracts can be used as source of natural antioxidants for the prolongation of the oxidative stability of cosmetic products. Additionally, they can replace synthetic antioxidants.
The objective of this study was to compare the content of selected complete dry feed labels for adult, healthy dogs and cats, emphasizing the accordance with the relevant EU requirements which have recently came into force. Additionally, simple calculations of the energy content were made to enhance the characteristics of the products available to the customer. The level of accordance reached in average 87% and 82% in dog and cat food respectively. It should be stated that the improvement of the labels content, as compared with 2011, was not significant. The key elements of the label information were either not improved or decreased (the statement of the necessity of constant access to water or daily dosage per animal). All evaluated products were typical maintenance foods, but their energy density was quite differentiated which may have some deleterious nutritional consequences associated with their long time supply.
