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.

Abstract: Alkaline liquid detergent composition comprising anionic surface active agents, and among them at least one soap and at least one phosphoric ester, non-ionic surface active agents, detergency builders, sequestering agents, optionally perfumes and/or dyes and/or other compatible additives, and water as a complement. Application to the cleaning of all washable hard surfaces.

Abstract: A composition for the automatic cleaning of toilet bowls includes at least one amine oxide, at least one appropriate colorant and at least one pH regulating agent, the composition being such that the pH of the aqueous mixture in the toilet bowl is about 6.3.+-.0.5. The composition is applied by filling containers designed to be used especially in the reservoir or tank of the toilet bowl.

Abstract: A sealing device for containers which forms a valve for automatic elimination of overpressurized gases that may form with the container is provided. The device is composed of a rigid cap having a flat crown and depending skirt, an elastic disk sector in contact with the underside of the flat crown and an inner cap having a circular crown with a circular cutout and raised circular rim on an upperside thereof. A flat circular protuberance on the underside surface of the disk sector, when the device is in use fits into and is surrounded by the circular crown portion, both of which are adapted to fit vertically over the orifice of the container. When in use, the circular crown exerts a crushing pressure on the upper portion of the elastic disk sector while at the same time the flat circular protuberance remains sufficiently elastic to allow gases overpressurized to vent from the container.
