The present invention relates to a suspension-type aqueous liquid detergent composition that imparts a soft quality to detergents (abrics).

The ability to wash and soften simultaneously eliminates the need for post-wash softening/rinsing cycles or the separate use of special-purpose softening compositions, making it easier for the user to use during the laundry operation. This is desirable because it is more convenient.

Several attempts have been made to formulate detergent compositions for textile laundry that exhibit the cleaning performance that modern users expect and at the same time provide sufficient softening effects.In the field of solid detergent compositions, anionic Anionic detergent-based solutions have been proposed by containing means to complex the detergent active ingredient and the cationic detergent active ingredient to overcome their natural incompatibility. .

To our knowledge, no proposals have been made for the formulation of aqueous liquid compositions based on structured active groups containing a combination U of anionic and cationic detersive actives.

We have discovered that this aliphatic amine can be stably incorporated into suspended aqueous liquid detergent compositions by formulating the composition in a suitable manner to impart flexibility during washing. .

Accordingly, the present invention provides: (a) nonionic detergent active substances and/or anionic derivatives of polyalkoxylated nonionic detergent active substances; and (b) anionic detergent active substances other than component (a). further comprising (c) a long tA aliphatic amine of effective m, the p of the composition
characterized in that H is higher than the snow-electric point of the amine;
Aqueous suspension detergent compositions for cleaning and softening textiles are provided.
