Abstract: The present invention is directed towards compositions which contain a crosslinked absorbent polymer and a water soluble low molecular weight compound. The water soluble low molecular weight compound reduces the rate at which water evaporates from the crosslinked absorbent polymer. The crosslinked absorbent polymers of this invention have a water retention value greater than or equal to about 6. This invention also is directed towards methods for preparing the compositions of this invention.
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: The hydroxybenzoate compounds of this invention are defined by the formula:
wherein Y is hydrogen, hydroxy, halo, a C1 to C6 alkyl or a C2 to C6 alkyl ether;
R is a C4 to C6 mono- or di-olefinically unsaturated hydrocarbon radical, a C4 to C7 mono- or di-acetylenically unsaturated hydrocarbon radical or a C2 to C3 acetylenically unsaturated hydrocarbon radical when at least one of X and Y is other than hydrogen and
X is hydrogen, hydroxy, halo, a C1 to C6 alkyl, a C2 to C6 alkyl ether or
in which A is selected from the group of X,
B is selected from the group of Y and
R1 is hydrogen, hydroxy, C1 to C6 alkyl, C1 to C6 alkoxy or —COOR2 in which R2 is C1 to C6 alkyl, a C2 to C6 olefinically unsaturated hydrocarbon radical or a C2 to C7 acetylenically unsaturated hydrocarbon radical.
Abstract: A cosmetic composition for rejuvenating the appearance of skin with reduced or minimal potential for skin irritation, in the form of a lotion, creme, solution or gel, or applied onto a carrier, includes about 0.5 to 50 wt. % in an aqueous, alcoholic or aqueous-alcoholic solution of a solvent-free, high molecular weight terpolymer of methyl vinyl ether-maleic anhydride-isobutylene, said composition having a pH of 1.5 to 5.
Abstract: A composition comprising a long-chain alkylpyrrolidone, a surfactant, and film-forming water-soluble polymer wherein the amounts of the components are such that on dilution with water, a clear liquid is formed. The composition may be used as a medium for agriculturally active ingredients as well as other active ingredients which are suitable for film formation, e.g., wood protectants, and the like.
Abstract: A process of making a cosmetically or pharmaceutically-acceptable emulsion or gel composition which comprises: (a) heating a reaction mixture comprising, by weight, about 5-70% of a vinyl monomer in about 30-95% of an oil as solvent, wherein said oil is selected from the group consisting of a silicone oil, a mineral oil and a water-insoluble organic ester and a free radical initiator, optionally in the presence of a crosslinking agent and/or an oil soluble surfactant, with agitation, under an inert gas, at about 40-150° C., wherein the oil is present in an amount sufficient to keep the resultant vinyl polymer in a stirrable state until the end of the polymerization, (b) adding a surfactant, if a suitable surfactant was not present during polymerization, and, (c) then adding water to form an oil-in-water, a water-in-oil or a water-in-oil-in-water emulsion or gel, in a volume ratio of oil-in-water of 30:70 to 10:90, or water-in-oil of 90:10 to 30:70.

Abstract: A method and associated apparatus for monitoring exposure to radiation, with compensation for temperature variation of a sensor and variations in the amount of radiation sensitive material in a dosimeter used in the method. The method utilizes a radiation dosimeter having a layer of radiation sensitive material on a substrate, the radiation sensitive material having an optical absorbance which varies in accordance with degree of radiation exposure and wavelength and which also varies in dependence on temperature. The radiation sensitive layer includes a substantially radiation impervious substance.
