FLAME OR FIRE RETARDING AGENTS AND THEIR MANUFACTURE AND USE

The invention relates to an agent，in particular a flame retarding agent and/or a fire retarding agent， for reducing the combustibility and flammability of various materials or matters， e.g. like wood and wood products， textiles， paper， cardboard， fibers and fabrics， paints， including composites and/or composite materials therewith， the manufacture of the composition and methods of using the agent and/or the corresponding combination of its constituents to reduce combustibility and flammability. An exemplary composition in dry form (powder) for 1 l of aqueous solvent， in particular for 1 l of water， contains borax in an amount of 30 to 70 wt.-%， boric acid of 30 to 70 wt.-%， sodium chloride (NaCl) in a maximum amount of less than 5 wt.-%， and， if desired， urea in an amount up to 5 g; based in each case on the composition as 100 wt.-%. However， the compositions are preferably free from urea.
