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.
