Claim 2
Dependent Claim 103 words
A water soluble crayon composition comprising (i) from about 50 to about 95 weight percent of one or more water soluble alkoxylation products of organic compound of about 8 to 22 carbons having at least one active hydrogen and an average molecular weight of from about 250 to about 3000, said average molecular weight being sufficient such that the one or more alkoxylation products is solid at room temperature, and (ii) coloring agent, wherein the water soluble crayon composition has a breaking strength of at least about 1200 grams and a viscosity of from about 10 to about 200 centistokes at 100° C.
Claim 3
Dependent Claim 94 words
The water soluble crayon composition of claim 1 wherein the one or more water soluble alkoxylation products comprise alkoxylation species having the formula: R.sub.1 [(CHR.sub.2 --CHR.sub.3 O).sub.m H].sub.t wherein R 1 is an organic residue of an organic compound having at least one active hydrogen, t is an integer of at least 1 up to the number of active hydrogens contained by the organic compound, R 2 and R 3 are the same or different and are hydrogen or alkyl (including hydroxy- and halo-substituted alkyl), and m is an integer of at least 1.
Claim 4
Dependent Claim 105 words
A water soluble crayon composition comprising (i) from about 50 to about 95 weight percent of one or more water soluble ethoxylation products of primary monohydric alcohol of about 8 to 20 carbons having an average molecular weight of from about 250 to about 3000, said average molecular weight being sufficient such that the one or more ethoxylation products is solid at room temperature, and (ii) about 1 to 30 weight percent of coloring agent, wherein the water soluble crayon composition has a breaking strength of at least about 1200 grams and a viscosity of from about 10 to about 200 centistokes at 100° C.
