A quickly dissolving carrier granule made up of wood fibers, mineral
filler, and starch-based or dextrin-based adhesive binder. The wood
fibers in these granules are preferably wood fibers ranging from about 10
microns to about 2 mm in length. Typically, at least about 35 weight-% of
the fibers are retained on a 50-Mesh U.S. Sieve Series screen. The wood
fibers in this invention are derived from sources that are substantially
free of resins such as urea-formaldehyde resin and of diphenylmethane
diisocyanate resin. Typical binders are soluble dextrin binders or a
viscous corn starch, wheat starch, rice starch, tapioca starch, potato
starch, or sago starch binders. The granules have a Resistance to
Attrition of at least 90%. Also disclosed is a method of making such
granules. The disclosure also describes carrier granule compositions
which are made up of from 10 to 90 weight-% of carrier granules wherein
the binder is a dextrin binder and from 90 to 10 weight-% of carrier
granules wherein the binder is a food-based or industrial-based native
starch.
