A microcrystalline cellulose-based excipient having improved compressibility, whether utilized in direct compression, dry granulation or wet granulation formulations, is disclosed. The excipient is an agglomerate of microcrystalline cellulose particles and from about 0.1% to about 20% silicon dioxide particles, by weight of the microcrystalline cellulose, wherein the microcrystalline cellulose and silicon dioxide are in intimate association with each other. The silicon dioxide utilized in the novel excipient has a particle size from about 1 nanometer to about 100 microns. Most preferably, the silicon dioxide is a grade of colloidal silicon dioxide.

Provided is a cellulosic composite comprised of cellulosic material and a binder. The binder comprises a reaction product of an amine and a reactant in the form of an amino-amide intermediate. To the amino-amide is added an aldehyde or ketone to form a curable binder composition. The composition when mixed with cellulosic material and cured forms a cellulosic composite.

An emulsion comprising water as the continuous phase, a wax as the discontinuous phase, an emulsifier and a preservative having the general structure:wherein R1 can be a heterocycle containing nitrogen and sulfur, such as thiazolyl, isothiazolyl, or thiadiazolyl, which can optionally be substituted with C1–C6 alkyl; R2 can be hydrogen or C1–C6 alkyl, specifically hydrogen; n is 0, 1, 2, or 3; each instance of R3 can independently be hydrogen, C1–C6 alkyl, phenoxy, C1–C6 alkoxy, halo, amino, C1–C6 alkylamino, di C1–C6 alkyl amino, imidazolyl, thiazolyl, isothiazolyl, thiadiazolyl, thienyl, furyl, pyrryl, naphthyl, phenyl, halophenyl, C1–C6 alkyl phenyl, or C1–C6 alkoxyphenyl. The preservative may be added to the emulsion after the emulsion is formed. The emulsion can be incorporated into a gypsum product such as gypsum board or gypsum wood fiber board. The gypsum product may be made by forming a slurry containing gypsum, water, and the emulsion into a solid product. A method for improving the water resistance of a lignocellulosic composite product prepared by mixing lignocellulosic material with a binder to form a mixture and solidifying the mixture in a selected configuration to form the composite product may include adding to the mixture an emulsion as described above.
