Bactericidal tabletting composition and tablets formed therefrom

DETAILED DESCRIPTION We claim: 1.
A tablet formed without a lubricant comprising: dichloroisocyanuric acid or alkali metal salt thereof: 10-40% weight carbonate as alkali metal bicarbonate or a mixture of alkali metal bicarbonate and carbonate: 20-50% weight characterized in that the composition also has present 20 to 50% weight succinic acid powder having a particle size such that a maximum of 2% weight is retained on a 400 micron screen and no more than 25% weight passes through a 100 micron screen.
2.
A tabletted composition according to claim 1 wherein the succinic acid powder is characterized by the following size ranges: on a 400 micron screen: 2% weight through a 400 micron screen but retained on a 200 micron screen: 20-80% weight through a 200 micron screen but retained on a 100 micron screen: 10-50% weight through a 100 micron screen: 4-25% weight.
3.
A tabletted composition according to claim 1 wherein the components of the composition comprise: sodium dichloroisocyanurate: 10-40% weight sodium carbonate: 0-15% weight sodium bicarbonate: 20-50% weight succinic acid: 20-50% weight.
4.
A tabletted composition according to claim 3 comprising: sodium dichloroisocyanurate: 25% weight sodium bicarbonate: 35% weight sodium carbonate: 5% weight succinic acid: 55% weight.




Description:
FIELD OF THE INVENTION This invention relates to a novel bleaching, disinfecting, bactericidal and sterilizing tablet and more particularly to a tablet of this type which contains dichloroisocyanurate and carbonate components and which tablet must be quickly dissolved in water with effervescent evolution of carbon dioxide and release of available chloride.
The invention relates most specifically to such a tablet that can be prepared without the use of a lubricant.
BACKGROUND OF THE INVENTION For a number of reasons including package and dosage considerations it is highly desirable to be able to form a bleaching, disinfecting, bactericidal and sterilizing formulation such as that just immediately described hereinbefore into tablet form
