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: 15
Claim 1
Independent Claim 119 words
An alkaline built liquid detergent composition comprising in an aqueous medium a nonionic detergent, a detergency builder, an alkaline agent and a polymeric structuring agent characterized in that it comprises: (a) at least 2% by weight of an alkoxylated fatty alcohol nonionic detergent or mixture thereof having in the alkylene oxide radical an over-all ratio between the number of ethylene-oxide units and the number of propylene- and/or butylene-oxide units of less than 9; (b) from 2 to 30% by weight of an alkaline agent; (c) from 10 to 30% by weight of a detergency builder; (d) 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.
Claim 2
Dependent Claim 119 words
An alkaline built liquid detergent composition comprising in an aqueous medium a nonionic detergent, a detergency builder, an alkaline agent and a polymeric structuring agent characterized in that it comprises: (a) at least 2% by weight of an alkoxylated fatty alcohol nonionic detergent or mixture thereof having in the alkylene oxide radical an over-all ratio between the number of ethylene-oxide units and the number of propylene- and/or butylene-oxide units of less than 9; (b) from 2 to 30% by weight of an alkaline agent; (c) from 10 to 30% by weight of a detergency builder; (d) 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.
Claim 3
Dependent Claim 33 words
