Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 47 words
A process for decreasing the build up of inorganic incrustations on fabrics and on washing machine components during multiple washing cycles characterized by the addition to the washing cycle of a co-builder based on a carbohydrate or carbohydrate derivative having a DE of 0.5 to 20 inclusive.
Claim 2
Dependent Claim 17 words
The process according to Claim 1, characterized in that the carbohydrate or carbohydrate derivative is a maltodextrin.
Claim 3
Dependent Claim 19 words
The process according to Claim 2 characterized in that the maltodextrin has a DE of 8 to 17 inclusive.
Claim 4
Dependent Claim 20 words
The process according to Claim 1, characterized in that the co-builder as such is added directly to the washing bath.
Claim 5
Dependent Claim 33 words
The process according to Claim 4, characterized in that the co-builder is added in amount ranging from 1 g/washing cycle to 40 g/washing cycle, preferably from 2 g/washing cycle to 20 g/washing cycle.
