Descrizione generale
Brij® 35 is a common nonionic surfactant, which has a dodecyl apolar core and a polyoxyethylene chain-formed polar surface. It comprises several hydrophobic and hydrogen-bonding interaction sites with target analytes. Brij 35 is edible and non-toxic.
Applicazioni
Brij® 35 solution has been used to develop a novel hexafluoroisopropanol (HFIP)/Brij-35 supramolecular solvent (SUPRAS)-based liquid-phase microextraction (LPME) of parabens. It has also been used to study the formation of water-in-ionic liquid (w/IL) microemulsions in IL 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]).
Azioni biochim/fisiol
Brij® 35 is known as the “green” modifier in micellar liquid chromatography due to its capability to simulate the biopartitioning process. It forms water-in-ionic liquid (w/IL) microemulsions with IL 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) in the bulk phase. It can also form reverse micelle-type aggregates inside [bmim][PF6] in the absence of added water.

Brij-35, a common and popular nonionic surfactant, is shown to form water-in-ionic liquid (w/IL) microemulsions with IL 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) as the bulk phase. The presence of w/[bmim][PF6] microemulsions is hinted by the significantly increased solubility of water in Brij-35

A novel supramolecular solvent (SUPRAS) based on hexafluoroisopropanol (HFIP)/Brij-35 was proposed for liquid-phase microextraction (LPME) of parabens in water samples, pharmaceuticals and personal care products. Brij-35 is a cost-effective and non-toxic non-ionic surfactant, but it has a high cloud point
