Abstract
Abstract An additive composition for a granular detergent comprising: (a) a cationic surfactant having the general formula (I) ##STR1## wherein R 1 and R 2 independently represent an alkyl group having 12 to 26 carbon atoms, R 3 and R 4 independently represent an alkyl group having 1 to 4 carbon atoms, a benzyl group, a hydroxyalkyl group having 2 to 4 carbon atoms, or a polyoxyalkylene group having 1 to 5 mole oxyalkylene units, and X represents a halogen atom, ##STR2## and (b) a nonionic cellulose derivative, the ratio of component (a)/component (b) in a weight basis of 99.9/0.1 to 50/50. This additive composition can provide an excellent soft finish or touch to fabrics, especially cotton fabrics to be washed while simultaneously washing the fabrics during a fabric laundering operation when this additive composition is incorporated into a granular detergent.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
An additive composition for a granular detergent comprising: (a) A quaternary ammonium salt having the general formula (I): ##STR5## wherein R 1 and R 2 independently represent an alkyl group having 12 to 26 carbon atoms, R 3 and R 4 independently represent an alkyl group having 1 to 4 carbon atoms, a benzyl group, a hydroxyalkyl group having 2 to 4 carbon atoms, or a polyoxyalkylene group having 1 to 5 mole oxyalkylene units, and X represents a halogen atom, ##STR6## and (b) a nonionic cellulose derivative, the ratio of component (a)/component (b) in a weight basis of 99.9/0.1 to 50/50, said additive composition being granulated from a mixture of the molten quaternary ammonium salt having the general formula (I) and the nonionic cellulose derivative by (i) spraying the mixture, followed by cooling or (ii) solidifying the mixture upon cooling, followed by crushing.
Claim 2
Dependent Claim
144 words
An additive composition for a granular detergent comprising: (a) A quaternary ammonium salt having the general formula (I): ##STR5## wherein R 1 and R 2 independently represent an alkyl group having 12 to 26 carbon atoms, R 3 and R 4 independently represent an alkyl group having 1 to 4 carbon atoms, a benzyl group, a hydroxyalkyl group having 2 to 4 carbon atoms, or a polyoxyalkylene group having 1 to 5 mole oxyalkylene units, and X represents a halogen atom, ##STR6## and (b) a nonionic cellulose derivative, the ratio of component (a)/component (b) in a weight basis of 99.9/0.1 to 50/50, said additive composition being granulated from a mixture of the molten quaternary ammonium salt having the general formula (I) and the nonionic cellulose derivative by (i) spraying the mixture, followed by cooling or (ii) solidifying the mixture upon cooling, followed by crushing.
