Activated peroxygen detergent

Claim 2

BUILT LAUNDRY DETERGENT COMPOSITION CONSISTING ESSENTIALLY OF (A) WATER SOLUBLE AIONIC SULFONATE OR SULFATE DETERGENT, (B) SODIUM SILICATE AS THE PRINCIPAL BUILDER SALT, (C) A PEROXYGEN COMPOUND AND (D) AN ACTIVATOR FOR SAID PEROXYGEN COMPOUND SAID ACTIVATOR HAVING A CARBOXYLIC ACYL GROUP, SAID PEROXYGEN COMPOUND BEING ONE WHICH REACTS WITH SAID ACTIVATOR TO FORM THE CORRESPONDING PERCARBOXYLIC ACID ON ADDITION OF SAID COMPOSITION TO THE WASH WATER, THE RATIO OF C TO D BEING FROM ABOUT 8:1 TO 2:1 OF THE STOICHIOMETRIC RATIO FOR SAID REACTION, THE RATIO (A + B):C BEING AT LEAST 2:1 AND THE RATIO B:C BEING OVER 1:1, AND WHEREIN SAID SODIUM SILICATE HAS AN NA2O:SIO2 RATIO OF ABOUT 1:2 TO 1:3.

Claim 3

Composition as in claim 1 in which the peroxygen compound is sodium perborate or sodium percarbonate and the activator is one which reacts therewith to form a perbenzoic acid.

Claim 4

Composition as in claim 2 in which the activator is a m-chlorobenzoyl amide.

Claim 5

A composition as in claim 2 in which said b:c ratio is at least 2:1.

Claim 6

Built laundry detergent composition consisting essentially of (a) water soluble sodium linear alkylbenzenesulfonate detergent, (b) sodium silicate as the principal builder salt, (c) a peroxygen compound and (d) m-chlorobenzoyl dimethylhydantoin as activator for said peroxygen compound, said peroxygen compound being one which reacts with said activator to form the corresponding percarboxylic acid on addition of said composition to the wash water, the ratio of c to d being from about 8:1 to 2: 1 of the stoichiometric ratio for said reaction, the ratio (a + b):c being at least 2:1 and the ratio b:c being over 1:1 wherein said sodium silicate has an Na2O:SiO2 ratio of about 1:2 to 1:3, and said composition also containing nonionic detergent and sodium carboxymethylcellulose.

Claim 7

Built laundry detergent composition consisting essentially of (a) water soluble sodium linear alkylbenzenesulfonate detergent, (b) sodium silicate as the principal builder salt, (c) a peroxygen compound and (d) m-chlorobenzoyl dimethylhydantoin as activator for said peroxygen compound, said peroxygen compound being one which reacts with said activator to form the corresponding percarboxylic acid on addition of said composition to the wash water, the ratio of c to d being from about 8:1 to 2: 1 of the stoichiometric ratio for said reaction, the ratio (a + b):c being at least 2:1 and the ratio b:c being over 1:1 wherein said sodium silicate has an Na2O:SiO2 ratio of about 1:2 to 1:3, and said composition also containing nonionic detergent and sodium carboxymethylcellulose.
