Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
145 words
A granular detergent or detergent additive composition comprising, by weight: (a) from about 0% to about 95% of a surfactant selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof; and (b) from about 1% to about 95% of a fabric care agent consisting of particles comprising, by weight: (i) from about 25% to 100% of a compound of the formula ##STR8## wherein R 1 and R 2 can independently be C 12 to C 20 hydrocarbyl groups; and (ii) from 0% to about 25% of imidazoline compound of the formula ##STR9## wherein R 1 and R 2 can independently be C 12 to C 20 hydrocarbyl groups; and the weight ratio of (i) to (ii) is at least about 3:1; and said particles having an average diameter of from about 20 to about 200 microns.
Claim 2
Dependent Claim
145 words
A granular detergent or detergent additive composition comprising, by weight: (a) from about 0% to about 95% of a surfactant selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof; and (b) from about 1% to about 95% of a fabric care agent consisting of particles comprising, by weight: (i) from about 25% to 100% of a compound of the formula ##STR8## wherein R 1 and R 2 can independently be C 12 to C 20 hydrocarbyl groups; and (ii) from 0% to about 25% of imidazoline compound of the formula ##STR9## wherein R 1 and R 2 can independently be C 12 to C 20 hydrocarbyl groups; and the weight ratio of (i) to (ii) is at least about 3:1; and said particles having an average diameter of from about 20 to about 200 microns.
