Abstract: A method of maintaining as well as restoring the condition of weathered asphalt shingles and strips which are applied to flat roofs, pitched roofs, or vertical walls. The process involves applying resaturant neat or as a water emulsion. Suitable resaturants include fatty acid methyl esters, petroleum distillates, and water emulsions thereof. The process restores the suppleness and softness of the weathered shingles or strip and adds about three years to the lifetime of the roof. The process may be repeated for additional lifetime extension.
Abstract: Silanes of the general formula
are prepared, wherein R1, R2 and R3 in the molecule are the same or different and represent aliphatic or aromatic hydrocarbon groups, R4 is a divalent hydrocarbon group with 4 to 12 carbon atoms and a lateral hydroxyl group, wherein the hydrocarbon group can be interrupted by an ether oxygen, R5 is a hydrophilic, ionic group. A method for synthesizing these compounds is described. The silanes greatly lower the surface tension of aqueous solutions, the surface tension being reduced to values of about 23 mN/m. The silanes are biologically degradable and have pronounced surfactant properties.
Abstract: A dampening water composition for a lithographic printing plate comprising polyvinylpyrrolidone and at least one compound selected from the group consisting of acetylene alcohol, acetylene glycol, n-butyl alcohol, isobutyl alcohol, secondary-butyl alcohol, tertiary-butyl alcohol, a compound of (CH3)3C—O—(—CH2—CH2—O—)p—H wherein p represents an integer of from 1 to 3, 3-methoxy-3-methylbutanol, 3-methoxybutanol, a compound represented by the following formula (I) and a compound represented by the following formula (II).
Abstract: The present invention relates to methods of using an entrapping agent, preferably cyclodextrin, to reduce the odor emitted by an aqueous latex-based coating material, in particular a latex-based paint.

Abstract: A fatty acid and/or an alkyl ester of a fatty acid and isethionic acid are allowed to react at a temperature of not more than 130° C. The present invention provides a process for preparing a fatty ester of isethionic acid or a salt thereof exhibiting an ameliorated hue and smell and in which few by-products are produced.
Abstract: A method for mixing an organic chemical substance with a carrier solvent, wherein the carrier solvent comprises at least one fluorinated solvent A selected from the group consisting of (perfluorohexyloxy)methane and tridecafluorohexane.
Abstract: The present invention teaches the composition of terminally modified, amino, polyether, siloxanes, known henceforth as amino siloxane alkokylates, and their use as adjuvants. The amino siloxane alkoxylates of the present invention enhance the efficacy of agrichemicals on plants as compared to conventional TSE's alone. The amino siloxane alkoxylates have at one end, an amine functionality and at the other end, a polyalkyleneoxide functionality.

Abstract: Compositions and methods are disclosed for filling prostheses for implantation into human soft tissue. The compositions comprise at least one nonionic surfactant, such as a polysorbate, which can be provided to fill a physiologically compatible shell or containment sac of the prosthesis. The liquid compositions of the present invention have a relatively high viscosity and are quickly absorbed from body tissues, metabolized and excreted with no known adverse effect. The compositions can be injected into the physiologically compatible shell either before, during or after the surgical implantation procedure.

Abstract: The invention relates to a wood-impregnating agent, which is an emulsion, dispersion or solution of a cationic, quaternary, amphoteric and/or special non-ionic surfactant, the surfactant or surfactants being poorly soluble in water and the dispersion or emulsion having a mean particle size diameter or a mean droplet size diameter smaller than 1 .mu.m. Preferable surfactants include cationic and/or quaternary surfactants or compounds from the group of imidazolines, benzyls, alkyls, dialkyls, monoalkyl-trimethyl, dialkyl-dimethyl, methyl-dialkoxy-alkyl, dialkylmethylbenzyl, diamidoamine and/or cationic and/or quaternary surfactants or compounds from the group of complex diquaternary compounds and/or the group of compounds which assume a cationic character in acid medium and/or non-ionic compounds from the group of fatty amine oxides, amine ethoxylate, and/or adducts of an ethylene oxide, which can be protonated on an heteroatom and/or amphoteric compounds from the group of betaines and/or ampholytes.
Abstract: The present invention teaches silicone polyether copolymers with a low degree of polymerization (3 to 4 Si units) provide control for foams generated by organosilicone based surfactants in water without the need for an additional antifoam component. The copolymer foam control agent is a compound of the formula(CH.sub.3).sub.3 SiO[SiO(CH.sub.3).sub.2 ].sub.X [SiOCH.sub.3 R.sup.1 ].sub.Y Si(CH.sub.3).sub.3wherein X+Y=1 to 2, Y.gtoreq.1, R.sup.1 is an alkyleneoxide group of the formula C.sub.a H.sub.2a O(C.sub.3 H.sub.6 O).sub.z R.sup.2 wherein a=3 to 4, z is 1 to 15, R.sup.2 is hydrogen, a hydrocarbon radical of 1 to 4 carbons or acetyl. This invention provides compositions for use in agricultural formulations that give improved foam control for foams generated from organosilicone surfactants in aqueous systems. The copolymer foam control agent is soluble in a surfactant matrix comprised of an organosilicone surfactant alone or in mixtures with short chain conventional surfactants.
