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.
