Descrizione

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.
