Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
A granular built detergent composition which comprises: a. from about 2% to about 40% by weight of an organic synthetic detergent selected from the group consisting of nonionic, zwitterionic, and anionic detergents and mixtures thereof; b. from about 0.02% to about 5% by weight of a substantially water-insoluble microcrystalline was having a melting point in the range from 35° C to 115° C and saponification value less than 100 or mixtures thereof; and c. from about 10% to about 90% by weight of detergency building salt or mixtures thereof; said wax in intimate admixture with the said organic detergent.
Claim 2
Dependent Claim
99 words
A granular built detergent composition which comprises: a. from about 2% to about 40% by weight of an organic synthetic detergent selected from the group consisting of nonionic, zwitterionic, and anionic detergents and mixtures thereof; b. from about 0.02% to about 5% by weight of a substantially water-insoluble microcrystalline was having a melting point in the range from 35° C to 115° C and saponification value less than 100 or mixtures thereof; and c. from about 10% to about 90% by weight of detergency building salt or mixtures thereof; said wax in intimate admixture with the said organic detergent.
