ABSTRACT:
Cold water soluble methylated, ethylated or carboxymethylated non-gelatinized granular starch materials are provided which are particularly well suited for use as thickeners and/or rheology modifiers in latex paint compositions. Such starch materials have a methyl, ethyl or carboxymethyl degree of substitution (D.S.) of from about 0.15 to about 1 and have a ratio of total inorganic anion content (in weight percent on a starch material dry solids weight basis) to methyl, ethyl or carboxymethyl D.S. of about 14 or less.
