Abstract:
The present invention relates to methods to achieve improved cleaning of both wet washable and dry cleanable fabrics. The present invention is carried out by exposing the fabrics to an aqueous vapor and a lipophilic fluid, optionally, but preferably followed by an extraction of both.
Abstract:
The present invention relates to automatic home laundering processes for cleaning or refreshing fabric articles, especially articles of clothing, linen and drapery. The present invention also relates to automatic home laundering of mixed loads of fabric articles comprising machine washable fabric articles and dry clean only fabric articles. The laundering medium is characterised by a siloxane, preferably a cyclic siloxane.
Abstract:
The present invention relates to a method for electrically coalescing emulsions especially those containing lipophilic fluid. The present invention is also directed to a method to treat fabrics wherein such an emulsion is created during the treatment process and requires electric coalescence prior to reuse of the lipophilic fluid.
Abstract:
A cleaning agent or a rinsing agent having no flash point which comprises a chlorine-free fluorine-containing compound having a vapor pressure at 20 DEG C of 1.33 X 10 Pa or more and one or more components having a vapor pressure at 20 DEG C less than 1.33 X 10 Pa and optionally an additive such as an antioxidant; a method for cleaning which comprises cleaning with the cleaning agent and rinsing and/or vapor cleaning utilizing a vapor being generated by boiling the cleaning agent or a condensate thereof; a method for separating a soil which comprises contacting a cleaning agent in a cleaning tank with a condensate of the vapor of the cleaning agent in a soil separating tank, to thereby continuously separate and remove a soil contained in the cleaning agent; and a cleaning apparatus.
Abstract:
Cleaning sheets comprise an additive that is selected to enhance the pick up and retention of particulate material from surfaces, while minimizing the amount of residue left on the surface being cleaned. If the type of additive and level of additive on the cleaning sheet are not carefully selected, the sheet will leave a residue on the surface being cleaned resulting in filming and streaking of the surface that is unacceptable to consumers. The additive is preferably selected from the group consisting of a wax, an oil, and mixtures thereof.
Abstract:
A stripping composition for urethane conformal coatings includes about 18 weight percent d-limonene; about 9 weight percent monoethanolamine; about 18 weight percent aromatic distilled spirits; about 30 weight percent dipropylene glycol monomethyl ether; about 23 weight percent polyethylene glycol having an average molecular weight of about 300; and about 2 weight percent fumed silica.
Abstract:
There is disclosed a composition for removing long chain compounds, which are substantially insoluble in water, the use of the composition in such removal and methods of cleaning. The composition comprises an inert gel matrix within which is entrained a solvent which is capable of dissolving the material of interest. Examples of materials to which application of this composition is suitable include bitumen, tar, wax and chewing gum.
Abstract:
Compositions of nonafluoromethoxybutane and cyclopentane, nonafluoromethoxybutane and cyclohexane; nonafluoromethoxybutane, cyclopentane and acetone, nonafluoromethoxybutane, cyclohexane and acetone, nonafluoromethoxybutane, trans-1,2-dichloroethylene and cyclopentane; and nonafluoromethoxybutane, trans-1,2-dichloroethylene, cyclopentane and methanol are described. These compositions are useful as cleaning agents, displacement drying agents, refrigerants, heat transfer media, expansion agents for polyolefins and polyurethanes, aerosol propellants, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, and buffing abrasive agents.
Abstract:
A method for gelifying a carbon-based solvent composition is described. The gel-type cleaning composition includes one or more carbon-based solvents, one or more gelling agents and one or more polar solvents, as well as, optionally, a miscibility-promoting agent. The gelling agent is a finely divided silicon dioxide and the polar solvent is ethanol. The composition preferably includes petrol C, petrol E and petrol F. The method for producing such a gel includes the following steps: a) at least one carbon-based solvent and one gelling agent are mixed to produce a paste, b) a polar solvent is added to the paste to provide a gel and c) at least one carbon-based solvent is optionally added to the gel thus obtained. Application as a cleaning composition, particularly for chewing gum and graffitis.
