  • Viscous detergent composition capable of being diluted and process for producing it
    Patent number: 5057246
    Abstract: The invention relates to a concentrated, clear, liquid detergent composition capable of being poured and capable of being diluted with water to give a viscous diluted composition. This concentrated composition contains at least one anionic surface agent; a regulator of the viscosity of the diluted composition, consisting of at least one surface agent chosen from the group consisting of nonionic, amphoteric and zwitterionic surface agents, which is combined with at least one acid or its salt in such quantity that it is dissolved in the concentrated composition; the surface agent and the acid or the salt being chosen so that the viscosity of the diluted composition decreases, or increases and then decreases, when the quantity of acid or of its salt increases, for given surface agents, and water.
