Abstract

Abstract The invention relates to aqueous built liquid detergent compositions of high alkalinity comprising at least 2% by weight of an alkoxylated fatty alcohol or mixture thereof having an overall ratio between the number of ethylene oxide units and propylene- and/or butylene oxide units of less than 9; from 2 to 30% by weight of an alkaline agent; from 5 to 35% by weight of a detergency builder and from 0.1 to 1.0% by weight of an essentially single structuring polymeric agent; the composition having a pH equal to or above 11. The detergent compositions, which are suitable for both fabric- and dishwashing, show good detergency and stability, and improved viscosity and pourability.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 201 words
A suspending alkaline built liquid detergent composition having improved rheologic properties consisting essentially of: (a) from 2 to 15% by weight of nonionic detergent selected from the group of polyalkoxylated fatty alcohols having in the polyalkylene-oxide radical ethylene oxide units and propylene and/or butylene oxide units wherein the overall ratio between the number of ethylene oxide units and the number of propylene and/or butylene oxide units is less than 9; (b) from 2 to 30% by weight of an alkaline agent selected from the group consisting of alkali metal hydroxides, alkali metal orthosilicates, alkali metal metasilicates, alkali metal disilicates, and mixtures thereof; (c) from 5 to 35% by weight of a detergency builder selected from the group consisting of the alkali metal salts of triphosphoric acid, pyrophosphoric acid, orthophosporic acid, polymetaphosphoric acid, mixtures of said salts of said acids, carbonates, zeolites, citrates, nitrilotriacetate , and mixtures thereof; and p0 (d) from 0.1 to 1.0% by weight of a single structuring polymeric agent selected from the group of cross-linked polyacrylates; and (e) water; wherein said composition has a pH equal to or greater than 11 and a viscosity within the range of 0.3 to 3.0 Pa.s at 20° C. and 20 sec-1.
