Abstract

1284680 Inhibiting scale deposition JOH A BENCKISER GmbH CHEMISCHE FABRIK 15 Dec 1970 [27 Dec 1969] 59478/70 Addition to 1233128 Heading C1C [Also in Divisions C3 C5 and C7] Scale deposition in aqueous systems is inhibited or prevented by introducing into the system a sub-stoichiometric amount in relation to the hardness in the water, of a modified starch obtained by treatment with an aqueous solution of an organic phosphonic acid below the glutinization temperature of the starch (see Division C3).
