Abstract
The premature release of chlorine from chlorine-releasing bleaching agents in a particulate detergent, caused by the action on such a bleaching agent by some other component in the detergent, is prevented by compacting and granulating a mixture of said other component, preferably with additional constituents which do not have the chlorine-releasing effect, and then mixing those granules with the chlorine-releasing bleaching agent and other appropriate detergent constituents. The resulting novel detergent is a mixture of the thus-produced granules with particles of the said other appropriate detergent constituents.
Claims27
A method of improving chlorine retention of a particulate detergent composition including a chlorine-releasing bleaching agent and one or more other components which, if the chlorine releasing bleaching agent is exposed thereto, will tend to cause premature chlorine release, which consists essentially of compacting and then forming granules of said other component in the substantial absence of said chlorine-releasing bleaching agent and then mixing said granules with said chlorine-releasing bleaching agent.
The method of producing a particulate detergent composition having improved chlorine retention characteristics, which consists essentially of:
- (a) mixing premature release constituents including detergent, builder, filler and other components in the substantial absence of chlorine-releasing bleaching agent;
- (b) then compacting the mixture formed in step (a) and forming granules thereof;
- and
- (c) thereafter mixing said granules with one or more additional components including a chlorine-releasing bleaching agent.
A particulate detergent composition having improved chlorine retention characteristics consisting essentially of a mixture of a chlorine-releasing bleaching agent and granules prepared by compaction of an admixture comprising premature release constituents including detergent, builder, filler and other components in the substantial absence of chlorine-releasing bleaching agent.
