The invention relates to a process for forming a wood-base product comprising the steps of a) providing particles of wood, b) resinating the particles of wood with a binder, c) compressing the resinated particles of wood to form a wood-base product, wherein before, during or after step b) the particles of wood and/or the binder are brought into contact with a broken dispersion. The invention also relates to the use of a polyfunctional compound as demulsifier for breaking a wax-containing dispersion containing an aqueous phase as continuous phase, a disperse phase containing wax and at least one emulsifier. The invention further relates to a broken dispersion for hydrophobicizing lignocellulose-containing material, wherein the broken dispersion is obtainable by mixing at least mixed a wax-containing dispersion A) containing the following components: i) at least one aqueous phase as continuous phase, ii) at least one disperse phase containing wax, and iii) at least one emulsifier, with a demulsifier B) having at least one functional group. The invention additionally relates to a two-component system (kit-of-parts) containing at least two components A and B: a wax-containing dispersion A) containing at least one aqueous phase as continuous phase, at least one disperse phase containing wax, and at least one emulsifier, and a demulsifier B) having at least one functional group for breaking the wax-containing dispersion.

Provided is a composition for the preservation of wood and other cellulosic materials. The composition comprises a dispersion of micronized inorganic compounds and/or organic biocides in an organic carrier. Also provided is a method for making the composition.

The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.
