Abstract:
Cleaning compositions and methods of making and using the same are provided. The cleaning compositions of the present invention may include at least one alkyl 3-hydroxybutyrate and water, optionally including at least one surfactant and one or more additional additives. The cleaning compositions of the present invention, which are non-toxic and environmentally benign, can be useful to remove many types of soils from a range of different substrates in a variety of domestic, industrial, and/or institutional applications.
Abstract:
A removal composition is described, having a plurality of abrasive particles, an organic amine, antioxidant, biocide, colorant, corrosion inhibitor, cosolvent, defoamer, dye, enzyme, light stabilizer, odor masking agent, plasticizer, preservative, rust inhibitor, surfactant, thickener, or a combination comprising at least one of the foregoing; from 0 to 1% water, based on the total weight of the removal composition; and a ketal adduct of formula (I), wherein R 1 is C1-6 alkyl, R 2 is hydrogen or C1-3 alkyl, each R 3 , R 4 , and R 5 is independently hydrogen or Cl-6 alkyl, R 6 and R 7 are each independently hydrogen or Cl-6 alkyl, a=0-3, and b=0-1.
Abstract:
The present invention relates to compositions comprising fluorinated ketones, and at least two compounds selected from the group consisting of alcohols, halocarbons, hydrofluorocarbons, or fluoroethers. In one embodiment, these compositions are azeotropic or azeotrope-like. In another embodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
Abstract:
The present invention relates to compositions comprising fluorinated olefins and at least one alcohol, halocarbon, hydrofluorocarbon, or fluoroether and combinations thereof. In one embodiment, these compositions are azeotropic or azeotrope-like. In another emebodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.

Abstract:
Disclosed is a method for treating metallic surfaces, in which methanesulfonic acid formulations are used that contain less than 28 percent by weight of water and optional amines and/or other components.
Abstract:
Disclosed are compositions and methods for cleaning contaminated articles based on the provision of a zeotropic composition comprising (a) at least one flammable solvent having a boiling point at a first pressure; (b) at least one first nonflammable solvent having a boiling point at said first pressure which is less than about said first pressure boiling point of said flammable solvent; and (c) at least one second nonflammable solvent having a boiling point at said first pressure which is greater than about the first pressure boiling point of said flammable solvent.
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.
