An aqueous composition comprising a compound
- hydrocarbon
- wherein the compound has the formula:
- wherein R4 is selected from the group consisting of hydroxy or F,
- wherein F is selected from:
- —O—C(O)—R3—C(O)OH, and
- —NR1—C(O)—R3—C(O)OH,
- wherein R1 is selected from the group consisting of hydrogen, or optionally substituted straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals which have up to 100 carbon atoms which optionally contain one or more groups selected from —O—, —NH—, —C(O)—, —C(S)—, tertiary amino groups
- and quaternary ammonium groups
- wherein R3 is selected from a single bond or optionally substituted straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals which have up to 100 carbon atoms, which optionally contain one or more groups selected from —O—, —NH—, —C(O)—, —C(S)—, tertiary amino groups
- and quaternary ammonium groups
- with the proviso that R3 is not —CH═CH—,
- with the proviso that at least two of R4 are F, or
- wherein the compound has the formula:
- wherein one of R5 is hydroxy and one of R5 is a group of the formula
- and wherein F is as defined above and the dotted line is the bond to the carbon atom, or
- wherein the compound is a mixture of the following two isomers:
- and
- wherein F is as defined above, and
- wherein the compound or mixture is present in an amount of from about 0.1 to about 20 weight percent based on the weight of the aqueous composition.
