Abstract
Abstract The invention relates to aqueous, built liquid detergent compositions. The inclusion therein of a polysaccharide hydrocolloid as stabilizing agent may give rise to an unacceptable increase in viscosity or gelatin. By using as detergent active material a particular mixture of an anionic and a nonionic detergent material, such increase in viscosity or such gelatin is prevented. The composition is particularly suitable for inclusion therein of enzymes and an enzyme stabilizing system, such as a mixture of glycerol and sodium sulphite.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
63 words
An aqueous, built liquid detergent composition, comprising a mixture of detergent active materials and a builder salt in an aqueous medium comprising a polysaccharide hydrocolloid, characterized in that it comprises a mixture of an anionic and a nonionic synthetic detergent active material in a weight ratio of 85:15 to 50:50, based on the sum of the anionic and nonionic synthetic detergent active material.
Claim 2
Dependent Claim
63 words
An aqueous, built liquid detergent composition, comprising a mixture of detergent active materials and a builder salt in an aqueous medium comprising a polysaccharide hydrocolloid, characterized in that it comprises a mixture of an anionic and a nonionic synthetic detergent active material in a weight ratio of 85:15 to 50:50, based on the sum of the anionic and nonionic synthetic detergent active material.
Claim 3
Dependent Claim
17 words
A composition according to claim 1, characterized in that the weight ratio lies between 85:15 and 70:30.
Claim 4
Dependent Claim
17 words
A composition according to claim 1, characterized in that it further contains enzymes and an enzyme-stabilizing system.
Claim 5
Dependent Claim
20 words
A composition according to claim 3, characterized in that the enzyme-stabilizing system comprises a mixture of glycerol and sodium sulphite.
