摘要:
The present invention relates to acid granulates containing a redox-active substance. The redox-active substance is protected in this form against undesirable chemical interactions with atmospheric oxygen or other constituents. The granulates of the invention are preferably incorporated into dishwasher detergents, where the redox-active substances, e.g. a transition or main group metal salt or complex, acts especially as a silver corrosion protective agent.

A composition and method for cleaning and disinfecting of contact lenses that employ an electrical field applied to a lens that causes contaminating deposits to migrate therefrom is described. The composition of the invention includes a pair of component materials having different electrochemical potentials wherein the materials are substantially contained in a form wherein each material remains sufficiently physically separated when in contact with opposite sides of the lens such that the difference in electrochemical potential between the two materials is sufficeint to cause charged contaminating deposits to migrate from the lens. The method of the invention requires placing a contaminated lens between a pair of component materials having different electrochemical potentials wherein physical separation is maintained, preferably, by including one of the components in a gel while the other component is in solution or another gel. Preferably, one component of the pair of materials is an oxidizing agent while the second component is a reducing agent. An example of a suitable pair is hydrogen peroxide suspended in a carbopol gel and a solution of sodium theosulfate, as the reducing agent. A lens is coatd with the oxidant gel, placed in the reductant solution and held at room temperature for 2-4 hours, wherein the electrochemical field established between the pair achieves about a 29 % protein removal.

The invention concerns the use of organic redox compounds, in particular ascorbic acid, indole, methionine, N-(C1-C4 alkyl) glycines, 2-phenylglycine or coupler and/or development compounds selected from the group comprising diaminopyridines, aminohydroxypyridines, dihydroxypyridines, heterocyclic hydrazones, aminohydroxypyrimidines, dihydroxypyrimidines, tetraaminopyrimidines, triaminohydroxypyrimidines, diaminodihydroxypyrimidines, dihydroxynaphthalines, naphthols, pyrazolones, hydroxyquinolines, aminoquinolines, primary aromatic amines which have, in addition, a free hydroxy or amino group, or a hydroxy or amino group substituted with C1-C4 alkyl or C2-C4 hydroxyalkyl groups, at the ortho, meta or para position, and di- or trihydroxybenzenes as silver-corrosion protection agents in dishwasher washing agents, in particular low-alkali dishwaster washing agents.
摘要:
Die Erfindung betrifft einen Textilentfärber, insbesondere für Haushaltszwecke, der in wäßriger Lösung eine Entfärbeflotte für zu entfärbende Textilien bildet. Dieser zeichnet sich erfindungsgemäß aus durch ein lagerfähiges Pulvergemisch mit Thioharnstoffdioxid als entfärbender Wirkstoffkomponente, ferner mit Natriumcarbonat oder einem anderen wasserlöslichen Carbonat oder Hydrogencarbonat der Alkalielemente als Alkaliträger und mit einem Entschäumer zum Austragen von Sauerstoff aus der Entfärbeflotte oder mit einem Schaumverhüter zum Verhindern von Sauerstoff in der Entfärbeflotte. Vorzugsweise enthält die Mischung etwa 3 bis 20-25 Gew.% Thioharnstoffdioxid. Die Entfärbewirksamkeit kann trotz niedriger Konzentration von Thioharnstoffdioxid überraschend durch einen Zusatz an Harnstoff verbessert werden. Ein solcher Textilentfärber ist ausreichend stabil sowie lagerfähig, einfach zu handhaben und wesentlich verträglicher sowie schonender als bisher übliche Textilentfärber auf der Basis von Natriumdithionit. Er weist eine hohe Entfärbungswirksamkeit auf und ist in verschiedenen Temperaturbereichen, einschließlich bei Raumtemperatur, einsetzbar.
摘要:
A process is disclosed for the manufacture of a liquid detergent composition comprising a sulphiting agent and an enzyme system. Said enzyme system and said sulphiting agent interact together so as to generate odors which result in an odor deviation in said detergent composition. In the process of the invention, said enzyme system and said sulphiting agent are intimately mixed together separately from the remainder of the detergent composition so as to generate said odors outside the remainder of said detergent composition. Also disclosed is a enzyme premix consisting essentially of said enzyme system and said sulphiting agent.
摘要:
A preferably mildly alkaline aqueous liquid cleaning composition, especially but not exclusively adapted for use in automatic dishwashing machines comprising an enzyme, encapsulated bleach particles, a reducing agent in an amount of from 0.01 to 0.5% by weight and water in an amount of not more than 55% by weight is disclosed. The compositions show excellent enzyme stability.
