N addition, the gear proposed, apart from getting scalable, could be particularly useful for pharmaceutical scientists who ought to implement film-coating processes for non-traditional substrates (e.g., those having non-spherical or complex shapes with edges and folds, crucial thermal and 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 also a.M.; resources, A.G. and L.Z.; data curation, M.U., A.M. and M.C.; writing–original draft preparation, M.U. and also a.M.; writing–review and editing, M.C., L.Z. along with a.G.; visualization, M.U. and S.M.; supervision, A.G. and L.Z.; project administration, L.Z.; funding acquisition, A.G.

Physicochemical Efficiency 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 materials are Thapsigargin Data Sheet extensively applied as adhesives in medicine and cosmetology. Nevertheless, for numerous applications, their properties call for modification. Within this perform, the influence of Melissa officinalis on the properties of collagen films was studied. Collagen was extracted from Silver Carp skin. Thin collagen films were prepared by solvent evaporation. The structure of films was researched utilizing infrared spectroscopy. The surface properties of films had been investigated using Atomic Force Microscopy (AFM). Mechanical properties were measured also. Antioxidant activity was determined by spectrophotometric approaches using DPPH free radicals, FRAP, and CUPRAC strategies. Total phenolic compounds were determined by the Folin iocalteau technique. It was found that the addition of Melissa officinalis modified the roughness of collagen films and their mechanical properties. In addition, the obtained material has antioxidant properties. The parameters mentioned above are extremely significant in possible applications of collagen films containing Melissa officinalis in cosmetics.
