Abstract
Abstract Detergent compositions stable to chlorine separation are described, which as main constituents contain alkali metal phosphate, alkali metal silicate, a surfactant and granulate chlorinated triazine trione, the granules of the chlorinated triazine trione being coated with a thin layer of a hydrophobic substance. The surface-treated chlorinated triazine trione which constitutes an agent for producing the composition, is also described as is the use of the composition as a machine dish washing detergent or industrial detergent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A detergent composition comprising alkali metal phosphate, alkali metal silicate, a surfactant, a chlorinated triazine trione of the formula ##STR3## wherein X is Cl, Na or K, or when X is Na, the dihydrate thereof, and optionally conventional additives, characterized in that the chlorinated triazine trione of formula (I) is in the form of granules having a particle size of from 0.5 to 5 mm., said granules being coated with a hydrophobic layer consisting essentially of a thin layer of a diester selected from the group consisting of the diester of phthalic acid or adipinic acid with an alcohol having 4-18 carbon atoms, said diester being employed in an amount of 3-9% by weight, calculated on the amount of the chlorinated triazine trione of formula (I).
Claim 2
Dependent Claim
126 words
A detergent composition comprising alkali metal phosphate, alkali metal silicate, a surfactant, a chlorinated triazine trione of the formula ##STR3## wherein X is Cl, Na or K, or when X is Na, the dihydrate thereof, and optionally conventional additives, characterized in that the chlorinated triazine trione of formula (I) is in the form of granules having a particle size of from 0.5 to 5 mm., said granules being coated with a hydrophobic layer consisting essentially of a thin layer of a diester selected from the group consisting of the diester of phthalic acid or adipinic acid with an alcohol having 4-18 carbon atoms, said diester being employed in an amount of 3-9% by weight, calculated on the amount of the chlorinated triazine trione of formula (I).
Claim 3
Dependent Claim

Claim 7
Dependent Claim
109 words
An agent for producing a detergent composition, characterized in that the agent comprises granules of chlorinated triazine trione of the formula ##STR4## wherein X is Cl, Na or K, or the dihydrate of the triazine trione of formula (I) when X is Na, said granules having a particle size of from 0.5-5 mm., said granules being coated with a thin hydrophobic layer of a diester selected from the group consisting of the diester of phthalic acid or adipinic acid with an alcohol having 4-18 carbon atoms, said diester being employed in an amount of 3-9% by weight, calculated on the amount of the chlorinated triazine trione of formula (I).
Claim 8
Dependent Claim
109 words
An agent for producing a detergent composition, characterized in that the agent comprises granules of chlorinated triazine trione of the formula ##STR4## wherein X is Cl, Na or K, or the dihydrate of the triazine trione of formula (I) when X is Na, said granules having a particle size of from 0.5-5 mm., said granules being coated with a thin hydrophobic layer of a diester selected from the group consisting of the diester of phthalic acid or adipinic acid with an alcohol having 4-18 carbon atoms, said diester being employed in an amount of 3-9% by weight, calculated on the amount of the chlorinated triazine trione of formula (I).
