An additive composition for a granular detergent comprising: (a) a cationic surfactant having the general formula (I) <IMAGE> (I) wherein R1 and R2 independently represent an alkyl group having 12 to 26 carbon atoms, R3 and R4 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, CH3SO4, C2H5SO4, or <IMAGE> and (b) at least one nonionic surfactant selected from the group consisting of alkylethoxylates having an alkyl or alkenyl with 9 to 11 carbon atoms and having an average ethylene oxide addition mole number of 5 to 12, alkylethoxylates having an alkyl or alkenyl with 12 to 15 carbon atoms and having an average ethylene oxide addition mole number of 3 to 6, alkylphenylethoxylates having an alkyl or alkenyl with 6 to 13 carbon atoms and having an average ethylene oxide addition mole number of 3 to 8, sucrose mono- or di-fatty acid esters, and sorbitan mono- or di-fatty acid esters, the ratio of component (a)/component (b) in a weight basis of 99.5/0.5 to 50/50. This additive composition can provide an excellent soft finish and feeling to fabrics to be washed while simultaneously washing the fabrics under any laundering conditions, without causing the deposition of the additive composition on the washed fabrics, when this additive composition is incorporated into a granular detergent. |
