Patent ID: 7928048

Claim:
A softening detergent composition comprising: (a) 1 to 30% by mass of a clay mineral represented by formula (3): [Si 8 (Mg a Al b )O 20 (OH) 4 ] x− .Me x+ wherein each of a, b and x satisfies 0<a≦6, 0<b≦4, x=12−2a−3b, and Me is at least one member selected from the group consisting of Na, K, Li, Ca 1/2 , Mg 1/2 and NH 4 ; (b) 0.5 to 20% by mass of a sodium carbonate-hydrogen peroxide adduct; (c) 0.1 to 20% by mass of a compound represented by the following general formula (1) or (2): wherein R 1 is an alkyl group having 4 to 13 carbon atoms; R 2 is an alkyl group having 5 to 13 carbon atoms; M is a hydrogen atom, or an alkali metal atom, an alkaline earth metal atom, an ammonium or an alkanolamine, with proviso that when M is an alkaline earth metal atom, n is 2, and that when M is an alkali metal atom, an ammonium or an alkanolamine, n is 1, or a combination of both; (d) 0.4 to 20% by mass of a salt of a fatty carboxylic acid; a component corresponding to a surfactant other than component (d) which comprises 35-70% by mass of an alkylbenzenesulfonate; and 10 to 60% by mass of a component corresponding to a surfactant as prescribed in JIS K 3362:1998, wherein a mass ratio of the component (b) to the component (c) [component (b)/component (c)] is from 3/4 to 20/1.
