摘要：
1. A method of producing aluminum salt composition comprising: I) heating an aqueous solution of aluminum chloride compound having a molar ratio of aluminum to chloride ratio of 0.3: 1 to 3: 1, to a temperature of at least 50 ° C to the reflux temperature for a period time of at least 1 hour II) providing an aqueous solution containing alkaline earth metal source to obtain an aluminum salt solution with the adjusted pH value, having a pH of from 2 to 5 and wherein at least one basic organic buffer share at least one of the solutions: I) an aqueous salt solution containing aluminum and chloride, and II) an aqueous solution containing an alkaline earth metal, wherein the aluminum salt solution with the adjusted value of pH comprises an aluminum salt with a molar ratio of OH: Al of 2: 1 to 2.6: 1, wherein the molar ratio of the basic organic buffer to alkaline earth metal ion is from 0.22: 1 to 18: 1.2. The method of claim 1, further comprising adding an aqueous solution containing a zirconium compound, to a solution of aluminum salt with the adjusted value of the pH, to thereby obtain a salt of aluminum-zirconium solution having a molar ratio of aluminum to zirconium of 2:. 1 to 10: 1, wherein the zirconium compound is optionally ZrOCl.3. A method according to Claim. 1 or 2, wherein the temperature is from 50 ° C to 120 ° C, optionally from 50 ° C to 100 ° C, from 75 ° C to 100 ° C or from 90 ° C to 100 ° C.4. A method according to Claim. 1 or 2, wherein the time period is from 1 to 6 hours and optionally between 1 and 5 hours from 1 to 4 hours and from 2 to 5 hours apart, 2 to 4 hours or 2 to 3 chasov.5 . A method according to claim 1 or 2, wherein the molar ratio of the basic organic buffer to alkaline earth metal ion is from 0.3:. 1 to 18: 1, optionally from 0.4: 1 to 18: 1, 0.5: 1 to 18 : 1, from 1: 1 to 18: 1, from 1.5: 1 to 18: 1, from 1.9: 1 to 18: 1, from 2: 1 to 18: 1, from 1: 1 to 3: 1, from 1.5: 1 to 3: 1, 1.5: 1 to 2.5: 1, 1.5: 1 to 2: 1,1.
