The present application relates to the technical field of daily cleaning and washing products, and particularly to a double layer detergent tablet and a preparation method thereof. The double layer detergent tablet includes a color absorbing fiber and a solid detergent adhered to the color absorbing fiber, the solid detergent includes the following components by mass percentage: 8-30% of polyvinyl alcohol, 10-40% of surfactant, 0.5-5% of polyvinylpyrrolidone, 1-5% of glycerin, 0.5-5% of water softener, 0.1-1% of plant essence, 14-79.9% of deionized water. The surfactant is a mixture of an anionic surfactant and a non-ionic surfactant; the anionic surfactant is a mixture of sodium coco-sulfate and sodium alpha-olefin sulfonate; and the non-ionic surfactant is a mixture of alkyl glycoside, fatty alcohol polyoxyethylene ether, isomeric alcohol polyoxyethylene ether and fatty acid methyl ester ethoxy compound.

A detergent or cleaning agent, in particular a cleaning agent for hard surfaces, having at least two phases which are different from each other. The detergent or cleaning agent includes at least one first phase and at least one second phase that is different, with the at least one first phase being solid and the at least one second phase having at least one polymer and at least one polyvalent alcohol.

The present disclosure provides water soluble laundry detergent products comprising one or more non-fibrous sheets and at least one solid layer, wherein the at least one solid layer comprises a gel and a solidifying agent and is coated on one or more sides of the one or more non-fibrous sheets, is disposed between two or more of the non-fibrous sheets, or a combination thereof; and methods of their making and using.

A detergent composition comprising an enzyme and a bleaching compound and comprising two or more distinct regions, wherein the enzyme is located in a first distinct region and the bleaching compound is located in a second distinct region and further wherein a builder comprising an amino acid based compound and/or succinate based compound is located in the first distinct region. The compositions exhibit improved stability of the enzyme.

Described is a dual function cleaning tablet comprising: a first portion comprising an alkaline cleaning formulation; and a second portion comprising an acidic cleaning formulation.

A cleaning agent portion including a water-soluble wrapping and at least one composition for cleaning and/or caring for an automatic dishwasher, the composition containing at least i) an acid and/or ii) a buffer system consisting of at least one acid and at least one base, wherein the composition includes at least two parts, at least one part A being a compressed part and at least one part B being a non-compressed part or a further compressed part, an optionally compressed part B being compressed to a lesser extent than part A. The invention also relates to a method for producing the cleaning agent portions. The invention further relates to a method for cleaning and/or caring for an automatic dishwasher using the cleaning agent portion. The invention also relates to the use of and/or a method using the cleaning agent portion for cleaning and/or caring for an automatic dishwasher.

A method for producing a multiphase washing or cleaning agent shaped body, including the steps of: a) providing a first free-flowing washing or cleaning agent; b) providing a second washing or cleaning agent; c) feeding the first and second washing or cleaning agent to an injector; d) introducing the first free-flowing washing or cleaning agent and the second free-flowing washing or cleaning agent into a mold by way of the injector; e) solidifying at least one of the free-flowing first and second washing or cleaning agents in the mold, forming a multiphase washing or cleaning agent shaped body; f) removing the multiphase washing or cleaning agent shaped body from the mold, wherein the first and second free-flowing washing or cleaning agent are introduced into the mold through outlet openings in the injector, which are separated. The invention also relates to multiphase shaped bodies produced by way of this method.

A multicomponent composition separating surfactant and fragrance into separate phases to increase the fragrance release from the composition.

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.
