N addition, the equipment proposed, apart from becoming scalable, will be especially useful for pharmaceutical scientists who must implement film-coating processes for non-traditional substrates (e.g., those getting non-spherical or complex shapes with edges and folds, important thermal and Pimasertib Technical Information mechanical properties) at a small scale level.Author Contributions: Conceptualization, M.U. along with a.M.; methodology, A.M.; formal evaluation, M.U.; investigation, M.U. and a.M.; resources, A.G. and L.Z.; data curation, M.U., A.M. and M.C.; writing–original draft preparation, M.U. as well as a.M.; writing–review and editing, M.C., L.Z. as well as a.G.; visualization, M.U. and S.M.; supervision, A.G. and L.Z.; project administration, L.Z.; funding acquisition, A.G.

Physicochemical Overall performance of Collagen Modified by Melissa officinalis Extract. Cosmetics 2021, eight, 95. https://doi.org/10.3390/ cosmetics8040095 Academic Editor: Isabel Martins de Almeida Received: 10 September 2021 Accepted: 27 September 2021 Published: 30 SeptemberAbstract: Collagen-based components are widely applied as adhesives in medicine and cosmetology. Nevertheless, for numerous applications, their properties need modification. Within this function, the influence of Melissa officinalis around the properties of collagen films was studied. Collagen was extracted from Silver Carp skin. Thin collagen films had been ready by solvent evaporation. The structure of films was researched working with infrared spectroscopy. The surface properties of films have been investigated applying Atomic Force Microscopy (AFM). Mechanical properties were measured too. Antioxidant activity was determined by spectrophotometric procedures working with DPPH no cost radicals, FRAP, and CUPRAC strategies. Total phenolic compounds were determined by the Folin iocalteau system. It was located that the addition of Melissa officinalis modified the roughness of collagen films and their mechanical properties. Furthermore, the obtained material has antioxidant properties. The parameters pointed out above are extremely important in prospective applications of collagen films containing Melissa officinalis in cosmetics. Keywords and phrases: collagen; Melissa officinalis extract; incorporation; all-natural extract; adhesives; antioxidant activity1. Introduct.
