The growing demand of the biotechnology industry to generate sustainable, environmentally friendly and ecological products has led to the development of alternatives to the use of chemical products, an example of these alternatives are biosurfactants; such is the case of sophorolipids. They have become attractive microbial products due to their...
Lyotropic liquid crystals were formulated from the Tween 40/Span 20 surfactant mixture at an HLB of 11, using water as the solvent and canola oil as the lipid phase. Ternary diagrams were constructed and at concentrations where the ternary mixture formed liquid crystals, beta-carotene was included as a carrier molecule....
Los soforolípidos son moléculas tensoactivas producidas por Starmerella bombicola y otros microorganismos emparentados. La notable actividad surfactante de estas sustancias naturales es de gran interés debido a su uso potencial en diversas aplicaciones de la vida diaria en donde actualmente los surfactantes sintéticos y semisintéticos son los protagonistas, ofreciendo una...
Recientemente se han desarrollado investigaciones en el campo de la síntesis de materiales nanoestructurados y mesoporosos de sílice. En estas síntesis se utilizan agentes estructurantes orgánicos, esto es, tensoactivos iónicos y no iónicos, y una fuente de sílice. Los tensoactivos junto con la sílice se auto ensamblan formando estructuras supramoleculares...
This doctoral thesis research work describes the results of the interactions observed during formation of an inclusion complex in the presence of three surfactants, namely: sodium dodecyl sulphate, SDS, hexadecyltrimethylammonium bromide, CTAB, and Triton X-100, TX100. The inclusion complex was formed from beta cyclodextrin, βCD, that acted as host of...
