  • Patent number: 5665204
    Abstract: A process for deinking a printed wastepaper pulp slurry comprising:(a) adding to a printed wastepaper pulp slurry a deinking composition consisting essentially of a nonionic ethoxylated and propoxylated surfactant of the formula (I):R--O--(OCH.sub.2 CH.sub.2).sub.n --(OCH.sub.2 CHCH.sub.3).sub.m --(OCH.sub.2 CH.sub.2).sub.q --O--X (I)wherein n is a number from about 1 to about 50, m is a number from about 1 to about 50, q is a number from about 1 to about 50, and R and X are H or an alkyl, alkenyl, or aryl group containing from about 3 to about 35 carbon atoms;(b) washing the slurry in order to obtain a deinked paper pulp suspension and an ink suspension; and(c) separating the deinked paper pulp suspension from the ink suspension.

  • Patent number: 5658426
    Abstract: Deinking of printed paper is accomplished by repulping and defibering the printed paper in an alkaline aqueous medium containing a deinking composition to form an ink and pulp medium. The deinking composition is an alkoxylated lanolin derivative containing from about 55 to about 80% by weight of ethylene oxide and from about 15 to about 30% by weight of propylene oxide, based on the weight of the alkoxylated lanolin derivative.

  • Patent number: 5609722
    Abstract: Wastepaper containing printing ink is refined in the presence of the reaction products of epoxidized derivatives of C.sub.10 -C.sub.22 carboxylic acids with alkoxylated carbohydrate-derived polyols and the detached printing ink particles are subsequently removed from the paper stock suspensions by flotation or washing.

  • Patent number: 5505817
    Abstract: Wastepaper containing printing ink is refined in the presence of the reaction products of castor oil with an alkoxylated fatty acid, alcohol, amine, amide, phosphate ester, polyhydroxy alcohol, or sorbitan, and the detached printing ink particles are subsequently removed from the paper stock suspensions by flotation or washing.

  • Patent number: 5118439
    Abstract: The invention is a process for preparing a carbonate containing detergent slurry with reduced viscosity by incorporating in the detergent slurry from 0.5 to 10% of an alkylpolyglycoside and 0.5 to 10% of an alkali metal chloride, the percentage being by weight of the non-aqueous portion of the slurry.

  • Patent number: 4834903
    Abstract: Remarkably good surfactancy characteristics are exhibited by alkylene oxide (e.g., ethylene oxide, propylene oxide, etc.) adducts of relatively low degree of polymerication, (D.P.), long chain glycoside compositions of the sort which are predominantly composed of long chain monoglycoside species and in which the types and relative proportions of any long chain polyglycoside species contained therein are such that the average degree of polymerization of such long chain glycoside constituents is less than 2.7.The subject low D.P. long chain polyglycoside alkylene oxide adducts exhibit surfactancy and/or detergency characteristics at least about as good as, and in some respects substantially better than, the corresponding alkylene oxide adducts of higher D.P. long chain glycoside materials.
