MICROEMULSIONS AND THEIR USES
The invention relates to a microemulsion comprising water in an amount of 1-30 w %; sodium or potassium oleate, Na/K salts of tall oil fatty acid, and/or Na/K salts of C16-C18 saturated or unsaturated fatty acids in an amount of 10-40 w %; oleic acid, tall oil fatty acid, or C16-C18 saturated or unsaturated fatty acids in an amount of 2-40 w %; ethanol in an amount of 0-40 w %; glycerol in an amount of 5-40 w %; and liquid hydrocarbon(s) in an amount of 5-40 w %, up to a maximum or total of components parts of 100 w %. Moreover, methods of manufacture and uses of the microemulsion are disclosed.
METHODS FOR ENHANCING THE PRESERVATION OF CELLULOSIC MATERIALS AND CELLULOSIC MATERIALS PREPARED THEREBY
Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

Enhanced performance of wood and engineered wood products using combined durability and flame retardancy
A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives, while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapors, tars and chars. Using a cone calorimeter burn test method, dFR treated wood products show a significant reduction in heat release rate, mass loss rate and smoke generated values compared to untreated radiate pine.
METHOD FOR PRODUCING COPPER CARBOXYLATE, A WOOD PRESERVATIVE COMPOSITION COMPRISING COPPER CARBOXYLATE, AND A WOOD PRODUCT PRODUCED THEREFROM
