摘要： A method is disclosed for the preparation of granulated perborate salts having improved utility in compressible compositions such as those formed into denture cleanser tablets. The method broadly comprises forming a mixture of one or more perborate salts such as sodium perborate monohydrate and anhydrous sodium perborate, with a polymeric fluorocarbon such as polytetrafluoroethylene, with the polytetrafluoroethylene present in an amount ranging from about 0.01% to about 0.70% by weight of the perborate salt. The particles thus prepared exhibit combination of improved hardness and specific weight that facilitates their participation in the compressible cleanser composition, together with enhanced disintegration characteristics that are favorably imparted to the cleanser tablets.The present invention also includes the granular salts prepared by the method, which have a broad range of utility in detergents, cleansers and the like.

摘要： The described process relates to the production of carburizing agents by compacting carbon dusts with a binder, such as hydroxyethyl cellulose, with addition of water and an auxiliary gelling agent. The auxiliary gelling agents used is glyoxal and/or bases of an alkali metal or alkaline earth metal or ammoniacal water. At from 0.5 to 2% by weight the requirement of binder is so small that no noticeable changes in the analytical values for the carbon dust used appear. The molded bodies produced from the compositions are dried at from 20.degree. to 180.degree. C. Calcination is not required.

摘要： Agglomerated granular detergent compositions containing at least about 10% sodium tripolyphosphate on an anhydrous basis and from 4% to 20% of an alkoxylated nonionic surfactant are prepared by spraying on or otherwise adding an aqueous sodium silicate solution as an agglomerating agent. The rate of hydration of the sodium tripolyphosphate and the degree of agglomeration of the granular detergent composition is controlled by addition of a portion of the total surfactant to one or more dry ingredients other than a major part of the sodium tripolyphosphate and the addition of another portion of the surfactant to the major part of the sodium tripolyphosphate concurrent with or subsequent to the addition of the agglomerating agent to the sodium tripolyphosphate.
