摘要:
The efficiency by which pulp cooking liquor components penetrate the wood and enable lignin and resins to be removed from the cellulosic materials is increased by contacting wood chips and the like with a liquid mixture comprised of white liquor containing at least one surfactant selected from the group consisting of a polymethylalkylsiloxane; a co- and terpolymer of silicone and a polyhydric alcohol; an alkoxylated aryl phosphate; an alkoxylated branched alkyl phosphate; an alkoxylated branched alcohol; an alkyl polyglycoside, an alkoxylated alkyl polyglycoside; a mixture of alkali metal salts of alkyl aromatic sulfate, a sulfosuccinate and a silicone; and combinations thereof; for a residence time effective to extract resinous components without substantial degradation of cellulose and thereafter heating at least a portion of the resulting mixture and wood chips.

摘要:
Cleaning and disinfecting compositions containing one or more “green” surfactants are disclosed. The compositions may be present as micro-emulsions that generally include green disinfecting agents, green surfactants, and water. The composition may also contain other green ingredients such as linkers, pH adjusting agents, natural fragrances, natural insecticides, and other natural organic actives such as natural oils. The composition may be used as a green cleaning and disinfecting composition with performance comparable or superior to conventional cleaning and disinfecting products with less desirable ecological profiles.
摘要:
Cleaning compositions in the form of nano- or micro-emulsions and containing one or more green surfactants are disclosed. The composition may further include one or more green linkers. The presence of two or more green surfactants may synergistically improve the cleaning performance of the composition. Moreover, the presence of the one or more green linkers may also synergistically improve the soil removal or streak reduction performance of the composition. The composition may further include additional natural actives, such as natural fragrances, natural insecticides, natural insect repellants, and natural oils to provide prolonged release of the natural actives in a controlled manner. The green surfactants not only improve the ecological profile of the disclosed compositions but also allow the formation of stable micro- or nano-emulsions at room temperature with good cleaning performances.
摘要:
Eco-friendly, or “green”, cleaning wipes are disclosed. The wipes may include a substrate and a green concentrated aqueous cleaning composition impregnated therein. The wipes are dry to the touch before they are activated by water and applied to inanimate surfaces for cleaning. Because of the green concentrated cleaning composition and water-activation just before application, the disclosed wipes may clean larger surface areas and have longer shelf lives and lower weights for easy transportation, packaging and handling than conventional wet wipes that are pre-loaded with a diluted cleaning composition.

摘要:
Multi-functional wipes with desirable ecological profiles and improved performances are disclosed. The wipes may include a substrate and a cleaning composition, a disinfecting/sanitizing composition, and an optional fragrance composition releasably associated with the substrate. The compositions may be separated from one another and may be impregnated in or coated on distinct sections of the substrate. Unlike “wet” wipes preloaded with a dilute cleaning liquid, the disclosed wipes may be substantially dry and water-activated just prior to its application on a target surface.
摘要:
A process for making a self-dispersible, radiation curable coating composition involving: (a) providing a cationic oligomer; (b) providing an epoxy functional monomer; (c) providing a surfactant component; (d) providing a transfer agent; (e) providing a photoinitiator; and (f) mixing (a)-(e) to form the coating composition.
摘要:
A substantially water-free, water-washable, energy-curable composition includes an epoxy oligomer and/or urethane oligomer having at least two ethylenically unsaturated moieties, at least one alkoxylated polyol monomer having at least two ethylenically unsaturated moieties and capable of being copolymerized with the oligomer, and a surface active agent capable of being integrated into the molecular structure of the cured polymer and further capable of rendering the uncured composition dispersible in water. Optionally, the composition can contain a photoinitiator. The composition is self-dispersible in water and is especially suitable for use as a coating material for a printing screen.
