There is disclosed a preservative composition which is ultra stable in the presence of wood extractives comprising (a) an emulsion of a wood preserative grade creosote; (b) 5-95% water; (c) one or more pre-dispersed micronized pigments; (d) a rheology structuring agent present in an amount of 2.5 we
There is disclosed a preservative composition which is ultra stable in the presence of wood extractives comprising (a) an emulsion of a wood preserative grade creosote; (b) 5-95% water; (c) one or more pre-dispersed micronized pigments; (d) a rheology structuring agent present in an amount of 2.5 weight percent or less; (e) 0.25 to 10 weight percent of a soap which is an alkali metal salt of a wood derived resin acid; (f) 0.1 to 5 weight percent of a surfactant; (g) 0.25 to 2 weight percent of a natural or synthetic pigment modifying resins or anti-settle additive; and (h) 0.25 to 5 weight percent of a lignin sulfonate. The emulsion is produced under conditions of ultra-high sheer. A process for the manufacture of the preservative composition is also disclosed.

A preservative composition which is ultra stable in the presence of wood extractives comprising (a) an emulsion of a wood preservative grade creosote; (b) 5-95% water; (c) one or more pre-dispersed micronized pigments; (d) a rheology structuring agent present in an amount of 2.5 weight percent or less, said rheology structuring agent being selected from the group consisting of carboxyvinyl polymers having molecular weight sufficiently high to enable said polymers to impart thixotropic properties to the composition, modified hydrogenated castor oil, bentonite clays, fumed silica, polysaccharides, naphthalenes, fatty acid derivatives and water soluble polyethylene oxides having molecular weight sufficient to enable said polyethylene oxides to impart theopectic properties to the composition; (e) 0.25 to 10 weight percent of a soap which is an alkali metal salt of a wood derived resin acid; (f) 0.1 to 5 weight percent of one of the surfactants selected from the group consisting of nonylphenyl ethoxylates, alkanolamides, soya lecithins, ethoxylated sorbitan esters, alkyl and glycol esters, sulfonated castor oils, amine ethoxylates, acrylic copolymers, fluorinated surfactants, poly(organosiloxane) surfactants, fatty acid soaps, sodium lauryl sulfates, octyl phenol ethoxylates, cetyl stearyl alcohol ethoxylates, propylene glycol ethoxylates, alkyl aryl ethers, ethylene oxide condensates and sulfonates; (g) 0.25 to 2 weight percent of one of the natural or synthetic pigment modifying resins or anti-settle additives selected from the group consisting of gum copol, gum rosin, vatica resins, shellac, wood rosin, tall oil rosin, chinese wood oil, high molecular weight primary amines derived from pine resin acids, casein, aliphatic resins, aromatic resins, coumaroneindene, terpene resins, polyterpene resins, terpene phenol, alkyd resins, rhodenes, polyurethane resins, silicone resins and unmodified hydrogenated castor oil; (h) 0.25 to 5 weight percent of a lignin sulfonate; said emulsion having been produced under conditions of ultra-high sheer.
