Abstract: A process for controlling the formation of undesirable by-products in an aqueous system containing residual halogenated 5,5-dialkyl hydantoins is disclosed. The process comprises the steps of treating the aqueous system with bromide ion and shocking the aqueous medium with free chlorine.

Abstract: A halogenated hydantoin product and method of producing same for use as e.g. a bleaching agent or disinfectant comprising a halogenated hydantoin of the formula ##STR1## wherein R is methyl or ethyl and X.sub.1 and X.sub.2 which may be the same or different are chlorine or bromine, either as the sole constituent or in admixture with halogenated dimethylhydantoins. The products are substantially dust-free, free-flowing and upon compaction form a solid product of high physical integrity.

Abstract: The generation of total and free halogen in aqueous solutions of halogenated hydantoins is potentiated by the use of a solubility agent selected from the group consisting of magnesium oxide, barium hydroxide, sodium carbonate, 5,5-dialkyl substituted hydantoin and mixtures thereof. The use of these solubility agents in combination with halogenated hydantoins, such as bromochloromethylethylhydantoin, is especially suitable for use as a toilet bowl cleaner.

Abstract: Readily dispersible wax compositions, which may be dispersed in either hot or cold water, are formed from finely divided mixtures of a bis-amide and a dispersing agent in an amount effective for dispersion. The dispersing agent is an acid neutralized salt of a N-[2-(2-hydroxyethylamino)ethyl] saturated fatty acid amide or N-[2-(2-aminoethylamino)ethyl] saturated fatty acid amide.

Abstract: Enhanced lubricating properties and good heat stability upon processing are imparted to thermoplastic materials such as polyvinyl chloride, polypropylene and acrylonitrile-butadiene-styrene resins by the incorporation therein of a polyglycerol ester of a C.sub.8 to C.sub.22 fatty acid. The ester is characterized by a degree of polymerization ranging from 2 to 8 and a degree of acid substitution ranging from 1 to 10.

Abstract: Spherical agglomerates of dihalodimethylhydantoins and dimethylhydantoins are prepared by feeding a mixture of the hydantoins together to the surface of an agglomerating disc in conjunction with a spray of water, and subsequently drying the agglomerates. These agglomerates possess a hard structural integrity and exhibit a uniform and controlled dissolution when placed in an aqueous environment, thereby rendering them suitable for a variety of applications including automatic dishwashing detergents, industrial bleaches, as well as disinfectants for cooling towers, swimming pools and spa waters.

Abstract: Substantial improvement in the heat stability of rigid plastic products, such as polyvinyl chloride, is obtained by incorporating therein glyceryl monostearate having less than 4% contained glycerine.
