Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
40 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 non-reducing carbohydrates and/or non-reducing carbohydrate derivatives.
Claim 2
Dependent Claim
25 words
