Abstract: What is described herein is a clear white-appearance, water-resistant, color ink-receptive film having a copolymer of (a) vinyl caprolactam and (b) dimethylaminopropyl methacrylamide coated thereon; preferably the weight ratio of (a):(b) is 50-95:50-5; optimally about 80:20. The ink-receptive film of the invention is capable of being printed from a color inkjet printer to form color images thereon which exhibit excellent long-term color stability towards light. These advantageous results are achieved herein while retaining the desired properties of rapid ink dry time, good print quality, highly resolved circular dots, and high, uniform optical density, characteristic of other systems.
Abstract: A gel system comprising propylene glycol alginate and basic aluminum acetate salt. Also, disclosed is a personal care formulation comprising a room deodorant gel employing said gel system.
Abstract: A stable medicated animal care formulation including, by weight;
(a) 0.1-10% of an active agricultural ingredient, of an animal care and/or veterinary reagents,
(b) 0.0002-40% of a microemulsion concentrate including:
(i) 0-10% of a castor oil ethoxylate or tristyryl phenol ethoxylate,
(ii) 0-1% of an ethoxylated phosphoric acid as pH buffer,
(iii) 0.0002-4% of a N—C8-C18 alkyl pyrrolidone and
(iv) 0-6% of a N—C1-C4 alkyl pyrrolidone,
(c) a surfactant with shampoo properties, and

Abstract: This invention relates to laundry detergent compositions, and, more particularly, to such compositions containing water soluble poly(vinylpyridine) betaine polymers containing a quaternary nitrogen and a carboxylic acid group, which polymers have effective dye complexing properties therein.
Abstract: This invention relates to a biocidal composition resistant to the formation of a gel and to the method for stabilizing a concentrate containing, in addition to the biocide, a carbodiimide in monomeric or polymeric form or a mixture thereof and a lipophilic/hydrophilic emulsifier mixture having a HLB of at least 7 comprising an oil and an alkoxylated ester of a polyhydroxylated compound, by adding to the concentrate between about 0.5 and about 15 wt. % of a saturated, aliphatic compound having a molecular weight of less than 400, selected from the group consisting of a polyhydroxyated alkanol and/or a polyhydroxylated ketone.
Abstract: A pH-dependent sustained release, drug delivery composition capable of being formed into tablets or pellets, wherein the release is controlled by a diffusion barrier formed by the interaction of a pH-dependent gelling material and a pH-independent non-gelling material, comprising a polymer matrix comprising, by weight, (a) 10 to 50% sodium alginate, (b) 2 to 15% propylene glycol alginate and (c) 40 to 80% of a pharmaceutical medicament.
Abstract: A polymer useful in oral care compositions which has a reactive group covalently bonded to a bactericide, flavorant and/or essential oil compound, said bond being hydrolyzable in aqueous solution to slowly release said compound into said composition.
Abstract: A stable, non-aqueous gum slurry which can be readily pumped or metered into a given formulation without swelling the gum or causing an excessive increase in viscosity, comprising a gum, a low molecular weight liquid polyethylene glycol as a non-solvent, and dissolved therein, a high molecular weight, solid polyethylene glycol as viscosifier.
Abstract: A single stage process, with recirculation of reactants, is provided herein for making N-vinylpyrrolidone or N-vinyl caprolactam at a high reaction rate and selectivity and at a predetermined conversion per pass. In this process a reaction mixture is formed by saturating a non-aqueous, liquid mixture of recirculating lactam, vinyl lactam and catalyst with acetylene at low temperatures and pressures to provide a high concentration of acetylene in the liquid, pumping the saturated solution into a reactor, reacting the mixture as a single liquid phase, cooling the reaction product, withdrawing a portion of the cooled product, recirculating the rest into the reaction mixture, and continuously feeding additional lactam and catalyst therein.
Abstract: A rheology modifier for use in aqueous or alcoholic compositions includes an aqueous two-phase polymeric composition of by weight, 5-75% of (a) a water-soluble polymer having (b) in situ-formed, substantially water-insoluble resinous particles of said polymer substantially uniformly dispersed therein, and (c) 25-95% of water.
