Claim:
A composition comprising at least one carbohydrate-containing nonionic surfactant compound of the general formula: Z-(E-R) n (I) where: Z is a carbohydrate moiety including a five membered ring or six membered ring, at least one E group is an amide linkage attached to the 1 position of the Z group formed between the nitrogen atom of the amide linkage and the carbon atom located at a position 1 of the carbohydrate moiety when numbering the carbohydrate moiety clockwise from the ring oxygen atom, while the other E groups are ester linkages with the oxygen atom of the carbohydrate group bonded to the carbonyl group of the ester linkage; R are independently a hydrogen atom or a carbyl group having between about 1 and 40 carbon atoms and the required hydrogen atoms to satisfy the valence and where one or more of the carbon atoms can be replaced by one or more hetero atoms selected from the group consisting of boron, nitrogen, oxygen, phosphorus, sulfur or mixture or combinations thereof and where one or more of the hydrogen atoms can be replaced by one or more single valence atoms selected from the group consisting of fluorine, chlorine, bromine, iodine or mixtures or combinations thereof; and n is an integer having a value from 1 to a number of hydroxy groups of the carbohydrate moiety prior to modification.
