Abstract
Softener-containing washing agents which, in addition to the customary components of washing agents, contain 0 to 10% by weight of a quaternary ammonium compound and 1 to 30% by weight of a softener system which comprises 10 to 90% by weight of a tertiary amine and 90 to 10% by weight of a crystalline sheet-silicate of the formula EQU Me.sub.2 Si.sub.x O.sub.2x+1 .multidot. yH.sub.2 O in which Me denotes an alkali metal ion or a proton, x denotes a number greater than 7, in particular from 7.5 to 23, and y denotes a number smaller than 7 x, in particular smaller than x. In the softener system, the tertiary amine is in a state of adsorption on the alkali metal silicate. The ammonium compounds, which are adsorbed on said silicate, produce a softening effect in the washing agent but on the other hand are compatible with anionic surfactants in the washing agent. produce a softening effect in the washing agent but on the other hand are compatible with anionic surfactants in the washing agent.
