This study involved cytotoxicity analysis, pH measurements, absorbance measurements and sterilization. The cytotoxicity analysis was conducted to determine the harmful degree of the cured epoxy resin. Aimed at identifying toxic agents in cured compounds, the cytotoxicity analysis involved absorbance measurements in an entire wavelength range. Cytotoxicity and absorbance results demonstrated that the extracts of all the tested resin samples had no cytotoxic effects on the cells of living organisms. The absorbance values obtained over the entire wavelength range did not point to the formation of aggregations, which proved that no toxic agents harmful to living organisms were extracted from the resin samples. Based on the results obtained, it can be concluded that all tested compounds, based on epoxy resins, which are also used as adhesives in various applications, are essentially safe materials when using such formulations in a cured state.<\/jats:p>","DOI":"10.3390\/polym14224915","type":"journal-article","created":{"date-parts":[[2022,11,15]],"date-time":"2022-11-15T02:32:16Z","timestamp":1668479536000},"page":"4915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Biological Effects and Toxicity of Compounds Based on Cured Epoxy Resins"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3592-8047","authenticated-orcid":false,"given":"Anna","family":"Rudawska","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Lublin University of Technology, Nadbystrzycka 36 St., 20-618 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1899-0300","authenticated-orcid":false,"given":"Katarzyna","family":"Sarna-Bo\u015b","sequence":"additional","affiliation":[{"name":"Department of Dental Prosthetics, Medical University of Lublin, Chod\u017aki 6, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrianna","family":"Rudawska","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, National Veterinary Research Institute, Aleja Partyzant\u00f3w 57, 24-100 Pu\u0142awy, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8407-0078","authenticated-orcid":false,"given":"Ewa","family":"Olewnik-Kruszkowska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Toru\u0144, Gagarin 7 St., 87-200 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6183-6029","authenticated-orcid":false,"given":"Mariaenrica","family":"Frigione","sequence":"additional","affiliation":[{"name":"Department of Innovation Engineering, University of Salento, Via Arnesano, 73100 Lecce, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,14]]},"reference":[{"key":"ref_1","unstructured":"Pertie, E.M.
