Patent ID: 8128849

Claim:
A method for producing an all purpose harmless fire retardant protein free composition that is adaptable to be incorporated into a range of differing material, of which said material forms an intermediate or finished product requiring fire retardant characteristics, said method including the steps of; A. adding acid to a sodium hydroxide solution to form a solution with a pH in the range of 1.0 to 3.0, the acid being selected from the group consisting of mono-carboxylic acid, anhydrous di-carboxylic acid and anhydrous tri-carboxylic acid and mixtures thereof, the mono-carboxylic acid being select from formic acid, acetic acid, stearic acid, benzoic acid and mixtures thereof, the anhydrous di-carboxylic acid being selected from the group consisting of oxalic acid, malonic acid, succinic acid, glutaric acid, and mixtures thereof, and the anhydrous tri-carboxylic acid consisting of citric acid, B. adding tetra-sodium-pyrophosphate and water to A for an endothermic process, C. adding calcium carbonates to the acidic solution B for the generation of an exothermic reaction, D. once composition C becomes clumpy, pouring composition C out onto a drying bed for drying, E. once the composition of step D is dried, subjecting the composition of step D to one or more of grounding, milling and grinding to achieve particles of less than 0.020 mm, F. encapsulating the particles of E with a surface coating material, the surface coating material being selected from the group consisting of polysaccharide, tristearate, a wax of a polyethylene based material, and mixtures thereof, wherein the encapsulation of step F provides means for the particles to remain inactive within the intermediate or finished product until the intermediate or finished product is ignited by fire.
