Hydrocolloid composition and dispersion-bound architectural formulations and emulsion paints comprising such compositions

摘要

A hydrocolloid composition comprising at least one sulpoalkyl-substituted polysacharide ether, is described. More particularly, the hydrocolloid composition includes: a) at least one sulphoalkyl-substituted polysaccharide ether, which is soluble in each of cold water and hot water, e.g., carboxymethylsulphoethylcellulose (CMSEC); b) optionally at least one nonionic polysaccharide ether having a thermoreversible gel point (or cloud point) of greater than 35° C. and less than 100° C.; and c) optionally at least one additive, e.g., an antioxidant. Also described are dispersion-bound architectural formulations and emulsion paints which comprise the hydrocolloid compositions of the present invention.
