Abstract: What is described herein are antimicrobial compositions which are defined blends of a 1,2-diol and phenoxyethanol which show broad activity against bacteria, fungi and mold spores. This activity is potentiated by the addition thereto of small amounts of a co-biocide for which the blend acts as a delivery system for the otherwise water-insoluble co-biocide.

Abstract: Urea-hydrogen peroxide-polyvinylpyrrolidone (PVP) in the form of a free-flowing powder is stable against decomposition in water and alcohol solvents. The product is obtained by spraying an aqueous solution of urea-hydrogen peroxide onto a fluidized bed of PVP and drying; it contains about 5%-20% by weight H.sub.2 O.sub.2 and less than about 5% water. The urea-hydrogen peroxide solution is applied onto the fluidized PVP bed at a predetermined rate, suitably about 0.5-30 g of solution/minute/kg PVP in the bed, and, preferably, about 1-3 g/min/kg PVP.

Abstract: A toothpaste composition is provided which includes the strontium salt of maleic anhydride-methyl vinyl ether copolymer. This ingredient is capable of desensitizing the nerve endings of a tooth in saliva or water because of an extension of the contact time of the strontium on the tooth surface.

Abstract: What is provided herein is a stabilized, aqueous, film-forming, antimicrobial composition of hydrogen peroxide. The active, oxygen-generating hydrogen peroxide component in the composition is stabilized in an aqueous-polyol solvent system of predetermined polarity containing PVP. In contrast, similar formulations without PVP experienced a loss of peroxide activity upon standing. Suitably, the composition herein includes about 1-20% by weight hydrogen peroxide, about 0.1-50% by weight PVP, and about 0.1-80% by weight of a polyol, the rest being water. Preferably, about 5-20% by weight of water is present in the composition. Additional solvents may be included therein, such as alcohols, ether oxides, esters, triglycerides of fatty acids, hydrocarbons, N-vinyl lactams, silicone oils, and polyether oligomers.

Abstract: What is described herein are polymerizable pyrrolidonyl 4,5-unsubstituted oxazoline monomers, homopolymers thereof, and copolymers with other monomers. A preferred polymerizable monomer compound is 2-(1-methyl-2-pyrrolidon-4-yl)-2-oxazoline. The polymers herein have excellent hydrotropic properties thus increasing the water solubility of organic compounds previously considered as water insoluble, and exhibit complexation with water soluble cosolutes.
