Water-borne paints containing reduced molecular weight polysaccharide derivatives that are resistant to enzyme hydrolysis. The water-borne paints are biostable, retaining at least about 80% of their initial viscosity 24 hours after they are inoculated with polysaccharide hydrolysis enzyme. A process for making the biostable water-borne paints has the steps: a) treating precursor polysaccharide derivative with polysaccharide hydrolysis enzyme in aqueous medium for a time sufficient to obtain reduced molecular weight polysaccharide derivative; and b) mixing the reduced molecular weight polysaccharide derivative with an effective amount of at least one other water-borne paint ingredient to obtain a water-borne paint.
