Summary: | Cellulosic materials such as paper, wood, cotton, rayon and the like are rendered flame retardant by the intimate association therewith of an effective flame retardant amount of a reaction product of aqueous solution of phosphoric acid or an acid ammonium phosphate and an alkylene oxide e.g., ethylene oxide. Amounts of said reaction product of at least, and preferably in excess of, 0.5 percent by weight are generally effective to render the cellulosic material flame retardant. Preferably the reaction product is rendered neutral before or after application to the cellulosic material in order that the material be rendered non-corrosive and non-irritating in nature. |
