Claim 1

A FOAM STABILIZING COMPOSITION SUITABLE FOR THE PREPARATION OF FIRE EXTINGUSHING FOAMS CONSISTING ESSENTIALLY OF AN AQUEOUS SOLUTION OF WATER-SOLUBLE DEGRADED PROTEIN FOAMING AGENTS WHICH ARE ALKALI-METAL SALTS OF HYDROLYSIS PRODUCTS OBTAINED BY HYDROLYZING A PROTEIN SELECTED FROM THE CLASS CONSISTING OF KERATINS, ALBUMENS, GLOBULINS, HEMOGLOBINS AND SEED MEAL PROTEINS BY MEANS OF AN ALKALINE COMPOUND SELECTED FROM THE CLASS CONSISTING OF OXIDES AND HYDROXIDES OF THE ALKALINE-EARTH METALS AND MAGNESIIM FOLLOWED BY REPLACING THE ALKALINE-EARTH METAL AND MAGNESIUM INTRODUCED BY THE ALKALINE COMPOUND WITH AN ALKALI-METAL TO FORM THE ALKALI-METAL SALTS OF THE HYDROLYSIS PRODUCT AND A COMPLEX SALT PREPARED FROM THE REACTION PRODUCT OF 1 TO 8% OF A METAL INTRODUCED AS A WATER-SOLUBLE METAL SALT, 2 TO 12% OF A FATTY ACID CONTAINING FROM 6 TO 12 CARBON ATOMS AND AN AMINE SELECTED FROM THE CLASS CONSISTING OF AN ALKANOLAMINE, A PRIMARY ALIPHATIC AMINE, AN ALKYLENEDIAMINE, A POLYALKYLENEPOLYAMINE AND MORPHOLINE; SAID WATER-SOLUBLE METAL SALT BEING OF A METAL WHICH FORMS A WATER-INSOLUBLE SOAP WITH SAID FATTY ACID, WHICH MIXTURE OF THE WATERSOLUBLE METAL SALT AND FATTY ACID IS FIRST SEPARATELY SOLUBILIZED IN THE WATER IN WHICH THE WATER-SOLUBLE METAL SALT IS DISSOLVED PRIOR TO BEING MIXED WITH THE FATTY ACID BY THE ADDITION OF ONE OF SAID AMINES; SAID AMINE BEING PRESENT IN SUFFICIENT QUANTITY TO SOLUBILIZE THE FATTY ACID AND WATER-SOLUBLE METAL SALT IN THE WATER IN WHICH THE WATERSOLUBLE METAL SALT IS DISSOLVED BEFORE BEING ADMIXED WITH THE FATTY ACID AND AMINE AND THE RESULTING WATER-SOLUBLE COMPLEX INTRODUCED INTO SAID FINAL FOAM STABILIZING COMPOSITION BUT IN LESS THAN SUCH EXCESS AS WILL PREVENT THE PRECIPITATION OF THE FOAM-STABILIZING COMPOSITION WHEN IT IS DILUTED WITH SUBSTANTIAL QUANTITIES OF WATER; THE QUANTITY OF SAID WATER-SOLUBLE DEGRADED PROTEIN FOAMING AGENTS BEING SUCH AS WILL PRODUCE A FOAM WHEN SAID FOAM-STABILIZING COMPOSITION IS DILUTED WITH A SUFFICIENT QUANTITY OF WATER TO PRODUCE A MIXTURE OF ABOUT 6% OF SAID COMPOSITION IN WATER AND THE RESULTING MIXTURE ASPIRATED WITH AIR.
