Abstract:
A detergent bar composition comprising : a) more than 60 % to 95 % by weight detergent active; and b) 0 to less than 40 % by weight inorganic particulates and/or other conventional ingredients; wherein the external surface of the shaped detergent composition comprises a polymer coating comprising at least one polymer layer, at least one of the polymer layers being a non radiation-curable material and having a water vapour permeability coefficient for water less than formula (I), which polymer coating is substantially water insoluble and has a melting point greater than 30°C but is abradable in use.
Abstract:
Aesthetically pleasing tablets, which are not provided with a covering made of a water insoluble film, comprise a covering made a of water soluble film which is arranged close to the moulded body. The tablets contain at least one swellable disintegration agent.
Abstract:
Coated solid bodies comprising a core of an active composition and having a water-soluble or dispersible micro-porous or net-coating. The coating improves the mechanical characteristics of the solid body and allows for good dissolution. The coated solid bodies preferably take the form of detergent tablets.
Abstract:
The present invention relates to a coated detergent tablet characterised in that the coating comprises a component which is liquid at 25 DEG C.
Abstract:
The invention relates to a composition for use in a dishwashing machine, characterized in that it consists of a base composition which becomes active substantially during the main wash cycle of the dishwashing machine; at least one particle having at least one core which contains at least one substance which becomes active substantially during the rinse cycle of the dishwashing machine; and a coating which substantially fully encloses the core(s) and contains at least one compound whose solubility increases as the concentration of a specific compound in the surrounding medium decreases. The invention provides for means to prevent a significant dissolution of the coating or a significant detachment of the coating from the core(s) until the start of the rinse cycle. The invention also relates to methods for running the dishwashing cycle in a dishwashing machine using the composition provided for by the invention.
Abstract:
A composition having a plasma-induced, graft polymerized, water-soluble coating for controlling solubility, chemical stability and physical properties is disclosed. A process for making such a composition is also disclosed which involves subjecting a particulate material to plasma after which a water-soluble organic monomer is graft polymerized onto at least a portion of the particulate material. The compositions are particulate or non-particulate in form and can be used in shampoos, skin care and other cosmetic products, deodorant products, laundry, dishwashing, carwashing or other similar detergent products.
Abstract:
The invention relates to a composition in the form of a tablet intended to be used in a water reservoir in the kitchen or in sanitary fittings, characterized by a basic composition which esentially develops its function after being added and the water reservoir is filled with water for the first time and by at least one particle with at least one core comprising at least one substance that develops its function basically after the first water filling has been at least partially evacuated from the water reservoir and fresh water is filled into the water reservoir, and a coating completely surrounding the core(s), which comprises at least one coumpond whose solubility increases as the concentration of a specific ion in the surrounding medium decreases, wherein the at least one particle is disposed in or on the tablet in such a way that the surface of the particle(s) is in direct contact with the surface of the basic composition surrounding the particle(s) and the concentration of the specific ion in the local medium of the particle(s) remains sufficiently high until the tablet has substantially and totally dissolved in order to prevent substantial dissolution of the coating or substantial separation of said coating from the core(s).
Abstract:
A packaged product (1) comprises the combination of a detergent tablet (20) with a packaging system (3) containing the detergent tablet (20). The tablet (1) has a diametrical fracture stress comprised between 15 and 65 kilo Pascal and the packaging system (3) is at least partly formed from a material (31) having a flat crush-ability comprised between 50 and 800 kilo Pascal.
Abstract:
The invention relates to two-phase or multi-phase washing and cleaning agent shaped bodies consisting of compacted, particle-shaped washing and cleaning agents, comprising builder(s), bleaching agents, bleach activator(s) and optionally other washing and cleaning agent components. Optimum stability of oxidation-sensitive materials is achieved by physically separating the bleach activator(s) from the oxidation-sensitive materials in a defined region of the shaped body.
