Abstract: Disclosed herein are bleaching systems that contain a peroxide and an activator. The activator is a tungsten containing compound, preferably sodium tungstate or tungstosilicic acid. When such bleaching systems are applied in an aqueous alkaline environment they can bleach mold, fungus, and the like.

Abstract: Disclosed is an ink composition which comprises water, an oil-soluble or alcohol-soluble dye, and a surfactant, said ink exhibiting a liquid microemulsion phase at a first temperature and, at a second temperature higher than the first temperature, separating into a mixture of an aqueous liquid phase and a liquid crystalline gel phase.

Abstract: Non-aqueous lamellar liquid crystalline lubricant compositions comprise an organic acid component or a salt thereof, an organic amine component and a non-aqueous solvent which maintains the liquid crystalline properties of a mixture of the organic acid or salt thereof and the organic amine. The organic acid component is selected from the group consisting of alkyl phosphonic acids, aryl phosphonic acids, alkyl sulfonic acids and aryl sulfonic acids. The weight ratios of the components are such that the compositions exhibit lamellar liquid crystalline properties, the weight ratio of organic acid to organic amine is in the range of about 1:1 to about 5:1 and the solvent comprises not greater than about 75 weight percent of the composition.

Abstract: A method of precipitating colloidal materials from aqueous systems and a dynamic bimetallic galvanic cell is disclosed, said cell including a metallic electrode which provides a source of flocculating agent and an inert electrode to which the metallic electrode is short circuited. When water containing colloidal particles is passed through the galvanic cell and the electrodes are short circuited, the metallic electrode provides a source of flocculating agent which coprecipitates with the colloidal particles, forming a sediment which can be readily removed. The cell is constructed to maximize the contact between the water and the electrode surfaces and to maintain the metallic electrode short circuited against the inert electrode as the metallic electrode is consumed.

Abstract: A suspension of solid particles in an organic or aqueous liquid comprises a lyotropic liquid crystal as suspension stabilizer.
