Abstract
Abstract The invention pertains to aqueous liquid detergent compositions of the suspending type which comprise a nonionic detergent active material and/or derivative thereof in admixture with an anionic detergent active material and/or cationic detergent active material, and electrolytes which consist of one or more salting-out electrolytes and one or more auxiliary electrolytes having a lyotropic number of 9.5 or above, the combination of said salting-out and auxiliary electrolytes giving improved stability.

Claim 1
Independent Claim
73 words
An aqueous liquid detergent composition of the suspending type which comprises a nonionic detergent active material and/or a derivative thereof in admixture with an anionic detergent active material and/or a cationic detergent active material, and electrolytes, characterized in that the electrolytes comprise one or more electrolytes having a salting-out effect on the nonionic detergent active material or derivative thereof, and one or more auxiliary electrolytes having a lyotropic number of 9.5 or above.
Claim 2
Dependent Claim
73 words
An aqueous liquid detergent composition of the suspending type which comprises a nonionic detergent active material and/or a derivative thereof in admixture with an anionic detergent active material and/or a cationic detergent active material, and electrolytes, characterized in that the electrolytes comprise one or more electrolytes having a salting-out effect on the nonionic detergent active material or derivative thereof, and one or more auxiliary electrolytes having a lyotropic number of 9.5 or above.
Claim 3
Dependent Claim
20 words
A composition according to claim 1, characterized in that the salting-out electrolyte is sodium tripolyphosphate, sodium silicate or sodium disilicate.
Claim 4
Dependent Claim
26 words
A composition according to claim 1 or 2, characterized in that the auxiliary electrolyte is an alkali metal iodide, -bromide, -chloride, -chlorate, -perchlorate, -rhodanide: or -nitrate.
Claim 5
Dependent Claim
70 words
A composition according to any of the preceding claims, characterized in that it comprises: 5 to 35% by weight of detergent active material, the weight ratio of the nonionic detergent active material and/or derivative thereof to the anionic detergent active material and/or cationic detergent active material being between 1:1 and 1:5, 5 to 30% by weight of the salting-out electrolytes, and 2 to 25% by weight of the auxiliary electrolytes.
