Abstract
Substantially solid compositions are provided having therein a compound with the structure of Formula I wherein A is a saturated ring formed by a plurality of atoms in addition to the N1 atom, the saturated ring atoms including at least one carbon atom and at least one of O, S, and N atoms, the substituent R1 bound to the N1 atom of the Formula I structure including either (a) a C1-24 alkyl or alkoxylated alkyl where the alkoxy is C2-4, (b) a C4-24 cycloalkyl, (c) a C7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C2-4, or (e) —CR2R3C≡N where R2 and R3 are each H, a C1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C2-4, the R2 and R3 substituents being each H, a C1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C2-4, Z is a value in the range of 0 to 10, and wherein Y is monovalent or multivalent and is sulfate, bisulfate, tosylate, or mixtures of sulfate and bisulfate as counterion. These compositions have reduced water uptake due to the Formula I compound.
