Estimating the term…
A particulate alkaline detergent contains an alkaline agent and an alkali perborate hydrate and/or an alkali carbonate peroxohydrate as bleaching agent. As a result of coating at least the alkaline agent or the bleaching agent with an alkyl glycoside or an alkyl glycamide, the detergent has a low tendency to caking as well as excellent cleaning capacity. The alkyl glycoside is a C.sub.6 -C.sub.10 -alkyl glycoside having a degree of polymerization of 1-4, and the alkyl glycamide has formula (I), wherein R.sub.1 is hydrogen or an alkyl group having 1-4 carbon atoms, and R.sub.2 is an alkyl group having 6-10 carbon atoms. A bleaching agent and an alkaline agent coated with the alkyl glycoside and/or the alkyl glycamide are also disclosed.
An alkaline detergent comprising
A particulate bleaching agent suitable for use in the preparation of the detergent, comprising an alkali perborate hydrate, an alkali carbonate peroxohydrate, or a mixture thereof that is coated with 0.5-20 parts by weight of a component selected from the group consisting of a C.sub.6 -C.sub.10 alkyl glycoside having a degree of polymerization of 1.0-4.0, a glycamide of formula (I) ##STR3## wherein R.sub.1 is hydrogen or an alkyl group having 1-4 carbon atoms, and R.sub.2 is an alkyl group having 6-10 carbon atoms,
A particulate water-soluble inorganic alkaline agent suitable for use in the preparation of a detergent, comprising a water-soluble inorganic alkaline agent that is coated with 0.2-10 parts by weight of a component selected from the group consisting of a C.sub.6 -C.sub.10 alkyl glycoside having a degree of polymerization of 1-4, a glycamide of formula (I) ##STR5## wherein R.sub.1 is hydrogen or an alkyl group having 1-4 carbon atoms, and R.sub.2 is an alkyl group having 6-10 carbon atoms,
A method of preventing a detergent composition from caking, comprising adding to said detergent composition a component selected from the group consisting of a C.sub.6 -C.sub.10 alkyl glycoside having a degree of polymerization of 1-4, a glycamide of formula (I) ##STR7## wherein R.sub.1 is hydrogen or an alkyl group having 1-4 carbon atoms, and R.sub.2 is an alkyl group having 6-10 carbon atoms,
