With the aim of enhancing their functional behavior, a new member of this family,\u00a0<i>N<\/i>,<i>N<\/i>\u2010dimethyl\u20102\u2010propylheptan\u20101\u2010amine oxide, bearing a branched alkyl tail (C<sub>10<\/sub>DAO\u2010branched) was synthesized and purified using a simple and easily scalable strategy starting from 2\u2010propylheptan\u20101\u2010ol. 2D\u2010nuclear magnetic resonance (NMR) and mass spectrometry confirm the obtainment of the desired product in high yield and purity. The protonation behavior of the branched surfactant is not affected by alkyl tail branching, as shown by potentiometric titrations. In contrast, surface activity and aggregation behavior of C<sub>10<\/sub>DAO\u2010branched is dramatically different from that of the linear analog\u00a0<i>N<\/i>,<i>N<\/i>\u2010dimethyldecyl\u20101\u2010amine oxide (C<sub>10<\/sub>DAO\u2010linear), in that it occupies a higher area at the solution interface and aggregates at much higher concentration, forming larger aggregates, as detected using tensiometry and dynamic light scattering (DLS), respectively. Aggregation behavior of C<sub>10<\/sub>DAO\u2010branched is less sensitive to pH variations. Foaming tests show that C<sub>10<\/sub>DAO\u2010branched is a more effective foam booster than its linear analog, in both acidic and basic solutions. The experimental results indicate that the branched surfactant can be used in applications that require enhanced and pH\u2010independent surface activity and foamability.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Synthesis, Surface Properties, and Self-Aggregation Behavior of a Branched N,N-Dimethylalkylamine Oxide Surfactant Fabozzi, A., Vitiello, R., Russo Krauss, I., Iuliano, M., De Tommaso, G., Amoresano, A., Pinto, G., Paduano, L., Jones, C.,\u00a0 Di Serio, M., D&#8217;Errico, G Journal of Surfactants and Detergents, 2019, 22(1), pp. 115\u2013124 https:\/\/doi.org\/10.1002\/jsde.12205 Abstract Amine\u2010oxide surfactants have emerged as highly stable, [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":1151,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[24,17],"tags":[],"class_list":["post-1150","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-new-surfactants","category-publications"],"acf":[],"_links":{"self":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1150","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/comments?post=1150"}],"version-history":[{"count":2,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1150\/revisions"}],"predecessor-version":[{"id":1153,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1150\/revisions\/1153"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/media\/1151"}],"wp:attachment":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/media?parent=1150"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/categories?post=1150"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/tags?post=1150"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
