The obtained results were applied for the determination of the concentration and composition of the Triton X-165 and biosurfactants mixture at the water\u2013air interface as well as the contribution of the particular component of the mixtures to water surface tension reduction and the mutual influence of these components on the critical micelle concentration. The determination of these quantities was based on both the commonly used concepts and a new one proposed by us, which assumes that the composition of the mixed monolayer at the water\u2013air interface depends directly on the pressure of the monolayer of the single mixture component and allows us to determine the surface concentration of each mixture component independently of surface tension isotherms shape. Taking into account the composition of the mixed monolayer at the water\u2013air interface, the standard Gibbs adsorption free energy was considered. The obtained results allow us to state that the concentration of both mixture components corresponding to their saturated monolayer and the surface tension of their aqueous solution can be predicted using the surfactants\u2019 single monolayer pressure and their mole fraction in the mixed monolayer determined in the proposed way.<\/jats:p>","DOI":"10.3390\/molecules27113600","type":"journal-article","created":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T08:01:18Z","timestamp":1654243278000},"page":"3600","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Thermodynamic Analysis of the Adsorption and Micellization Activity of the Mixtures of Rhamnolipid and Surfactin with Triton X-165"],"prefix":"10.3390","volume":"27","author":[{"given":"Edyta","family":"Rekiel","sequence":"first","affiliation":[{"name":"Department of Interfacial Phenomena, Faculty of Chemistry, Institute of Chemical Sciences, Maria Curie-Sk\u0142odowska University in Lublin, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Zdziennicka","sequence":"additional","affiliation":[{"name":"Department of Interfacial Phenomena, Faculty of Chemistry, Institute of Chemical Sciences, Maria Curie-Sk\u0142odowska University in Lublin, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1791-2893","authenticated-orcid":false,"given":"Katarzyna","family":"Szymczyk","sequence":"additional","affiliation":[{"name":"Department of Interfacial Phenomena, Faculty of Chemistry, Institute of Chemical Sciences, Maria Curie-Sk\u0142odowska University in Lublin, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8852-4495","authenticated-orcid":false,"given":"Bronis\u0142aw","family":"Ja\u0144czuk","sequence":"additional","affiliation":[{"name":"Department of Interfacial Phenomena, Faculty of Chemistry, Institute of Chemical Sciences, Maria Curie-Sk\u0142odowska University in Lublin, 20-031 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e0090","DOI":"10.1128\/JVI.00809-18","article-title":"Surfactin inhibits membrane fusion during invasion of epithelial cells by enveloped viruses","volume":"92","author":"Yuan","year":"2018","journal-title":"J.
