Patent ID: 8067354

Claim:
A softening detergent composition comprising: (a) 1 to 20% by mass of clay granules comprising as a main component a smectite clay mineral represented by the following general formula (I), provided that a Na/Ca mass ratio in the granules is less than 1.0: [Si 8 (Mg a Al b )O 20 (OH) 4 ] X− .X/ n [Me] n+ (I) wherein a, b, and x satisfy the formulas 0<a≦6, 0≦b≦4, 0.2≦x=12−2a−3b≦1.2; Me is at least one member of Na, K, Li, Ca, Mg and NH 4 ; and n is valency of Me; (b) 1.0 to 18% by mass of a nonionic surfactant; (c) 16 to 27% by mass of an anionic surfactant, provided that a salt of a fatty acid is excluded from said 16 to 27% range; (d) 10 to 35% by mass of an alkalizing agent, provided that a silicate is contained in an amount of 6% by mass or less of the softening detergent composition; and (e) 3 to 35% by mass of a crystalline aluminosilicate, wherein the composition further satisfies the following condition (ii) or both of conditions (i) and (ii): (i) said clay granules contain Na in an amount of 1.0% by mass or more; and (ii) said softening detergent composition contains a water-soluble Na salt and/or a water-soluble K salt in an amount corresponding to 23% by mass or more of the softening detergent composition when calculated as Na 2 O or K 2 O, wherein the total amount of 23% by mass or more is measured when both the water-soluble Na salt and a water-soluble K salt are present.
