A clear, concentrated, pourable liquid detergent composition capable of being diluted with water to give a viscous dilute composition. This concentrated composition comprises at least one anionic surface agent, a viscosity regulator for the dilute composition, consisting of at least one surface agent chosen from the group made up of nonionic, amphoteric and zwitterionic surface agents, used in combination with at least one acid or its salt in such a quantity that it is dissolved in the concentrated composition, the surface agent and the acid or the salt being chosen so that the viscosity V2 of the dilute composition decreases, or increases and then decreases, when the quantity of acid or of its salt increases, in the case of given surface agents and water. Application to compositions particularly for dishwashing. |
