Abstract:
A cleaning composition is releasably contained in a controlled-release pad or sheet, preferably enveloped within an apertured, formed-film cover sheet to provide a spot removable article. The article is pressed against localized stained areas on fabric surfaces to release the cleaning composition in a controlled manner. The article and fabric are then placed in a bag and agitated in a hot air clothes dryer to dry clean the entire fabric.
Abstract:
Disclosed are formulations for producing chemical solvent comprised of propylene glycol methyl/ether acetate which admixtures can be employed to clean a surface and which can be applied to cloths for the cleaning operation yet alleviate problems with solvent evaporation into the atmosphere. The figure shows and sets out a method for utilizing and disposing of cloths impregnated with such chemical formulations (11) whereupon the used cloths are enclosed first in polyethylene bags (23) then in a series of metal drums and containers (25, 27, 29, 31 and 33) and finally disposed of in an incinerator or kiln.
Abstract:
Laundering is improved by placing a nonwoven fabric (1) in the washing liquid to collect the dirt. The nonwoven fabrics used are composed of a combination of different plastic fibres, preferably polypropylene and/or polyamide and/or cationic cellulose fibres.

Abstract:
The present disclosure relates to compositions for use in open washing devices and methods of cleaning articles in open washing devices using the disclosed compositions. The disclosed compositions are effective at cleaning articles using the relatively less intense mechanical action of an open washing device (versus the more intense mechanical action of a closed automatic dishwasher). The disclosed compositions also generate some foam to provide visual confirmation that there is a composition in the sink, but not so much foam that the foam becomes excessive when the agitator is turned on or that the generated foam overflows the sink. Finally, the disclosed compositions are less irritating to an operator's skin, which is at least partly attributed to the lower levels of free alkalinity in the composition as measured as percent sodium oxide.
Abstract:
A method for applying a coating meeting a predetermined volatile organic compound (VOC) standard. The compound functions as a coating and plasticizer. The inventive method involves mixing acetone and terpene alcohol, or terpineol, to form a solvent system with a flash point of at least 140 °F. A resin is solubilized into the solvent system and forms a coating. The coating is cast over substrate surfaces to cure and dry. The solvent system produced by the inventive method can also be used in other applications including as a cleaning composition.
Abstract:
The present invention is directed to a method and an article for performing the method of monitoring a surfactant. A preferred embodiment of the invention, an article comprises a substrate having an image and a surfactant thereon. The substrate is formed from various known fabrics or materials capable of absorbing and retaining a substantial quantity of the surfactant. During use, as the surfactant is dissipated, the image changes in appearance thereby indicating the quantity of surfactant remaining on the substrate. In a preferred embodiment of the invention, the method and article of the present invention is effective for encouraging and making washing enjoyable for children and includes the use of an epidermal surfactant, such as soap, detergent, or other active ingredient.
Abstract:
The invention relates to a method for impregnating an object having pores by applying a liquid, heat-hardenable impregnating agent that is substantially free from water-soluble fractions in the pores, washing off the excess impregnating agent from the surface with water and hardening the impregnating agent by heating the impregnated object, wherein washing in performed in a first washing bath and an additional rinsing bath, wherein one or several surface active agents are added to the rinsing bath water and the washings are carried out in the washing bath with water that is substantially free from surface active agents or that contains less surface active agents than the rinsing bath water. The invention also relates to a device for implementing said method.
Abstract:
The invention relates to a hydrous, thixotropic detergent in paste form, containing the following in relation to the overall product: a) 5 to 40 wt. %, preferably 8 to 30 wt. % of an alkalinity support, chosen from alkali hydroxide and/or alkali carbonate; b) at least 5 wt. %, preferably 15 to 40 wt. % water; and c) more than 3 wt. %, preferably 5.5 to 30 wt. %, especially 6 to 15 wt. % non-ionic tensides. The product has a viscosity of 50 000 mPas to 250 000 mPas at 25 DEG C, measured with a Brookfield rotation viscometer (spindle no. 7) at 5 rotations per minute and a viscosity of 12 000 mPas to 80 000 mPas at 50 rotations per minute under otherwise identical conditions.
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.
