[Problems] To provide a softening detergent composition capable of washing a fibrous manufactured article having softening ability, and at the same time allowing a clay mineral to be less likely to remain on clothes. [Solving Means] A softening detergent composition containing (a) 1 to 20% by mass of clay granules containing 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: [Si8(MgaAlb)O20(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 NH4; and n is valency of Me; (b) 1.0 to 18% by mass of a nonionic surfactant; (c) 6 to 27% by mass of an anionic surfactant, provided that a salt of a fatty acid is excluded; (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, characterized in that the composition further satisfies at least one of the following conditions (i) to (ii): (i) Na is contained in an amount of 1.0% by mass or more of the clay granules; and (ii) a water-soluble Na salt and/or a water-soluble K salt is contained in an amount corresponding to 23% by mass or more of the softening detergent composition when calculated as Na2O or K2O (in a total amount of 23% by mass or more when both a water-soluble Na salt and a water-soluble K salt are contained).
