Abstract
Compositions are disclosed herein comprising an ester derivative of a glucan, wherein the glucan has a degree of substitution (DoS) up to about 3.0 with at least two organic groups that are individually ester-linked to the glucan, wherein (i) at least one of the organic groups is a cationic organic group, and (ii) at least one of the organic groups is a hydrophobic organic group. Methods are further disclosed for preparing these compositions, as well as various applications of using them.
Claims18
A composition comprising an ester derivative of a glucan, wherein the glucan has a degree of substitution (DoS) up to about 3.0 with at least two organic groups that are individually ester-linked to the glucan, wherein
- (i) at least one of the organic groups is a cationic organic group, and
- (ii) at least one of the organic groups is a hydrophobic organic group.
A method of producing an ester derivative of a glucan, said method comprising:
- (a) contacting a glucan with at least two esterification agents,
- wherein at least one of the esterification agents comprises a cationic organic group,
- wherein at least one of the esterification agents comprises a hydrophobic organic group,
- wherein at least one cationic organic group and at least one hydrophobic organic group are esterified to the glucan, thereby producing an ester derivative of the glucan,
- wherein the ester derivative of the glucan has a degree of substitution (DoS) up to about 3.0 with said cationic organic group and said hydrophobic organic group, and
- (b) optionally, isolating the ester derivative of the glucan produced in step (a).
