S. Tykhomyrova [et al.] // IOP Conference Series: Earth and Environmental Science. – Vol. 1254 : proc. of the 4th International Conference on Sustainable Futures: Environmental, Technological, Social and Economic Matters (ICSF-2023), May 22-26, 2023. – Electronic text data. – Kryvyi Rih, Ukraine, 2023. – art. 012009, [8 p.]. – URL: https://iopscience.iop.org/article/10.1088/1755-1315/1254/1/012009/pdf, free (accessed 14.03.2024).https://repository.kpi.kharkov.ua/handle/KhPI-Press/75512Biologically active polymer hydrogel transdermal materials based on gelatin, sodium alginate, modified by humic acids, were designed and researched. Literature review was carried out and it was proved that humic acids using is perspective for the functional effect on the biologically active polymer hydrogel transdermal properties. It has been found that effective processes for receiving biologically active polymer hydrogel transdermal materials based on gelatin, hydroxypropyl cellulose and sodium alginate can be carried out in different humic acids concentration while achieving an effective increase in hydrogel polymers structuring processes. It can be seen efficiently increasing biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate conditional viscosity and the specific electrical conductivity with an increase of humic acids content: from 114 to 135 sec and from 2350 to 2850 mkS/cm, respectively. Humic acids modification in biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate caused structure formation with high density, and resistance and with larger agglomerates in hydrogels. It was found that the gelatin-based biopolymer hydrogels modification by humic acids makes it possible to receive biologically active polymeric hydrogel transdermal materials with higher swelling degree. It is shown that the application of new biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate modified by humic acids allows improving the skin moisture-lipid balance. From the initial values of 34-36% moisture and 8-10 skin fat, they increase to 58-66% and 52-60%. So, designed polymer hydrogel based on gelatin, sodium alginate, modified by humic acids, are transdermal materials with good properties.enpolymeric hydrogel transdermal materialshumic acidstransdermal materialsgelatintransdermal propertiessodium alginateArticlehttps://doi.org/10.1088/1755-1315/1254/1/012009https://orcid.org/0000-0002-0851-5012https://orcid.org/0000-0002-5239-6364https://orcid.org/0000-0001-9124-9757https://orcid.org/0000-0001-5176-0200https://orcid.org/0000-0001-6934-2349
