10 g of Mg—Al hydroxide carbonate of the formula Mg6Al2(OH)16CO3 aq. (Pural MG 70, Sasol, Germany) are dispersed by stirring in 100 ml of deionized water at 70° C. for 15 minutes. Then a solution of 1.5 g of sebacic acid in 50 ml of deionized water is prepared with the addition of sodium hydroxide to a pH of approximately 9 and is added to the Mg—Al hydroxide carbonate suspension. Subsequently a solution of 2 g of stearic acid in a mixture of 50 ml of deionized water and 50 ml of isopropanol is prepared with the addition of sodium hydroxide to a pH of approximately 12 and heating to 70° C. and is added to the reaction mixture. The total mixture is stirred at 80° C. for 5 hours, and then the suspension is filtered, the solid product is washed repeatedly with deionized water and then the washed solid is dried in vacuo at 60° C.
