Abstract
A novel composition of matter as well as a straightforward single step process for the preparation or production of said novel composition of matter is disclosed. The composition affords a new type of nonionic carbohydrate based surfactants (NICBS), a type of biodegradable neutral surfactant. The produced surfactant compositions have both neutral, but polar polyhydroxyl heads and nonpolar tails that are linked via at least one amide bond and possibly another ester bond as well.
Claims15
A composition comprising:
- a polar group comprising a hydroxy or polyhydroxy carbohydrate;
- and
- at least one nonpolar hydrocarbon group attached to the polar group through a linker,
- where the groups are all non-ionic.
A process to prepare or produce non-ionic carbohydrate surfactants including the step of contacting a carbohydrate molecule with a nitrile.
