A composition for preparing an emulsion or microemulsion, the composition including the following components (A) to (D): component (A): an active ingredient having a solubility in water at 20 C. of 200 ppm or less; component (B): a water-insoluble solvent having no alcohol group; component (C): at least one nonionic surfactant selected from the group consisting of a polyoxyalkylene alkyl ether, a polyoxyalkylene alkenyl ether, a polyoxyalkylene alkyl amino ether, and a polyoxyalkylene alkenyl amino ether; and component (D): a monohydric alcohol having 8 to 12 carbon atoms.

Disclosed herein are compositions comprising a dispersion of solid particles of a substantially insoluble copper compound in an amount from 0.001% to 10% by weight of the composition; a boron-containing compound, a fluoride-containing compound, or a combination thereof; and an aqueous carrier; wherein the composition has a viscosity of 125 to 425 tenths of a millimeter (tmm) as measured using a penetrometer, and wherein at least 20% of the particles of the composition comprise particles having particle size greater than 25 microns. Also disclosed herein are methods of making and using the same.

A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.

The present invention relates to a composition for increasing the retention of a biocide in a glueline-treated glued-wood product, a method for increasing the retention of a biocide in a glueline-treated glued-wood product, a glueline-treated glued-wood product, a glue for producing a glueline-treated glued-wood product, and the use of a composition for increasing the retention of a biocide in a glued-wood product.
