  • Publication number: 20080275222
    Abstract: The present invention provides a method of reducing and/or neutralizing the allergenic protein content of natural rubber latex articles by exposing the natural rubber latex from which the article is made or the final natural rubber latex to an allergenic protein reducing compound. The allergenic protein reducing compounds for use in the present invention fall generally into two classes: (1) cationic compounds and (2) nitrogen-containing compounds. Quaternary ammonium salts are particularly preferred allergenic protein reducing compounds.

  • Publication number: 20070014687
    Abstract: The presently described technology provides for methods and compositions for deactivating the allergenic protein content of surfaces by treatment with an allergenic protein deactivating compound. Preferred allergenic protein deactivating compositions of the present technology comprise: (1) cationic compounds and (2) nitrogen-containing compounds. Quaternary ammonium salts are particularly preferred allergenic protein deactivating compounds. In some embodiments, allergenic protein deactivating formulations of the present technology additionally contain antimicrobial agents to deactivate microorganisms on surfaces, in the air, or both. Additives including cyclodextrins, soluble aluminum salts, urea, alkyl trimethyl ammonium salts, polyvinyl pyrrolidone, tannic acid, immobilized tannic acid, polyphenols, enzymes, benzyl benzoate, inorganic salts, surfactants, buffers, oils, waxes, solvents, preservatives and mixtures thereof are also envisioned for use with the described technology.

  • Patent number: 5124475
    Abstract: The invention encompasses methods for preparing in high purity and in high yield p-phenyl sulfonic acid acyl glycolates of the formula ##STR1## where R represents branched or straight chain alkyl having 6-12 carbon atoms by treating a phenyl ester or phenyl acyl glycolate of the formula ##STR2## where R represents branched or straight chain alkyl having 6-12 carbon atoms with a sulfonating agent to form intermediate sulfonation; transmuting the intermediate sulfonation products; and quenching the transmuted intermediate sulfonation products with a quenching reagent reactive with sulfur trioxide.

  • Patent number: 4066652
    Abstract: A class of hydrocarbyl substituted 8-hydroxyquinolines wherein the indicated substituent arises through the indirect alkylation of said quinolinol with a hindered aldehyde. These alkylates are useful metal collectors in hydrometallurgical extraction processes designed for the recovery of metal values from dilute aqueous solutions thereof.

  • Patent number: 3933872
    Abstract: A method for the preparation of fatty hydroxamates wherein an agitated anhydrous slurry of hydroxylamine sulfate and a lower alkanol solution of a lower ester of a C.sub.6 -C.sub.22 fatty acid is reacted with dimethylamine to provide the corresponding hydroxamic acid which is subsequently neutralized with dimethylamine or an alkali metal base to yield, respectively, the ammonium or alkali metal salt thereof.
