Abstract
Abstract A textile softening detergent composition contains from 5 to 70 wgt % surfactant, from 0.5 to 50 wgt % builder, from 1 to 20 wgt % crystalline laminated silicic acid and/or a corresponding alkali metal silicate and standard detergent aids. It is characterized in that the crystalline laminated silicic acid or its alkali metal salt of the general formula M.sub.2 Si.sub.x O.sub.2x+1 ·y H.sub.2 O in which x stands for a number larger than 7.0, M stands for sodium, potassium or hydrogen, and y stands for a number of from 0 to 25, shows one or more reflexes unassignable to quartz, tridymite and cristobalite in the X-ray diffraction diagram in the range of the d-values of 3.0-4.0·10 -8 cm. Process for rinsing textiles using the crystalline laminated silic acid or its alkali metal salts as a textile softening agent.
