A process for the use of an aqueous cleaning composition to remove organic material from a substrate. The cleaning composition preferably includes a nonionic surfactant and may also include a glycol ether solvent.

Aqueous cleaning

A liquid cleaning composition comprising a solvating agent and a rinsing agent, the ratio of the vapor pressure of said rinsing agent to the vapor pressure of said solvating agent being at least about 20 and the use thereof to clean substrates that have soil adhered thereto.

Cleaning composition comprising solvating agent and rinsing agent

An industrial cleaning process in which a contaminant comprising soldering flux and/or adhesive tape residue is removed from a substrate contaminated therewith, for example, a printed circuit board contaminated with rosin flux, comprising: (A) contacting the substrate with a terpene-based cleaning composition which is substantially free of water-soluble organic material, for example, a surfactant, for a period of time sufficient to solubilize the contaminant; (B) removing the composition and solubilized contaminant from the substrate by contact with water having a temperature of about 70.degree. F. to about 140.degree. F. (but preferably lower) for a period of time of no longer than about 10 minutes to provide a substrate having a contamination rating of no greater than about 14 micrograms NaCl equivalent/square inch (MIL-P-28809A), and to thereby form a mixture comprising the composition, contaminant and water; and (C) separating the water from said mixture, the separated water being substantially free of water-soluble organic material and having a chemical oxygen demand of no greater than about 1,000 ppm. and also a cleaning process utilizing a cleaning composition comprising a major amount of a monobasic ester to clean surfaces that are contaminated with an organic residue.

Cleaning process

A process for removing soil from a substrate which includes the use of a liquid cleaning composition comprising a solvating agent (for example, a monobasic ester) and a rinsing agent (for example, a perfluorocarbon), the solvating agent having:

Cleaning with solvating and rinsing agents

An aqueous cleaning composition having a pH of about 6 to about 8 and comprising a solution of the following ingredients: water, an organic solvent and an imidazoline-based cationic surfactant, each present in an amount effective to dissolve adherent soils from a substrate; and a nonionic surfactant in an amount sufficient to maintain said cationic surfactant in solution; and also a weak organic acid in an amount sufficient to impart to the composition said pH; wherein said composition is substantially free of any material which has an ozone-depletion factor of greater than about 0.15 and wherein said composition is substantially free of any material which would tend to form a solid with any of the ingredients comprising the composition, and its use to clean metallic and non-metallic surfaces.

Neutral aqueous cleaning composition

Cleaning process including use of solvating and rinsing agents

Disclosed is an industrial cleaning process in which a contaminant comprising soldering flux and/or adhesive tape residue is removed from a substrate contaminated therewith. The process comprises the steps of contacting the substrate with a terpene-based cleaning composition which is substantially free of water-soluble organic material; removing the composition and solubilized contaminant from the substrate by contact with water having a temperature of about 70.degree. F. to about 140.degree. F. for a period of time of no longer than about 10 minutes to provide a substrate having a contamination rating of no greater than about 14 micrograms NaCl equivalent/square inch (MIL-P-28809A), and to thereby form a mixture comprising the composition, contaminant and water. The process also comprises separating the water from said mixture, the separated water being substantially free of water-soluble organic material and having a chemical oxygen demand of no greater than about 1,000 ppm.

Personal care products containing bioemulsifiers

Methods and compositions are provided to facilitate the transportation and combustion of highly viscous hydrocarbons by forming reduced viscosity hydrocarbon-in-water emulsions, and in particular, bioemulsifier-stabilized hydrocarbon-in-water emulsions.

Bioemulsifier-stabilized hydrocarbosols

Methods and compositions are provided for the removal of soldering flux, screen inks and resists from contaminated surfaces. The compositions of the invention contain dibasic acid esters in combination with an appropriate emulsifying surfactant.

Dibasic esters for cleaning electronic circuits

A method for disposing of non-polar organic wastes including the steps of dissolving the organic waste in an organic solvent which is not environmentally objectionable, in combination with a suitable surfactant, mixing the resultant solution with a quantity of water to develop an emulsion in which the organic element is effectively dispersed in the water and thereafter mixing the emulsion with cement which, when allowed to solidify, encapsulates the organic waste within the solid cementitious mass. This solid mass is suitable for disposal in a landfill or the like. This invention is useful in safely disposing of environmentally hazardous organic wastes.

Method for the disposal of hazardous non-polar organic wastes

This invention relates to the reduction of oxidized sulfur compound (SOX) emissions produced during combustion of sulfur (S)-containing combustible compounds. More particularly, this invention provides a method for reducing such emissions wherein the combustible compound is mixed with an admixture of a water soluble and a water insoluble sulfur sorbent. Use of such admixtures, remarkably, produces a reduction in the SOX level far greater than would be expected based on the activity of each sorbent alone. Extremely viscous hydrocarbons can be burned as preatomized fuels, which can also be mixed with sorbent admixtures. Clean burning fuels comprising sulfur-containing combustible compounds and sorbent admixtures are also provided.

Method for reducing sox emissions during the combustion of

A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A cationic surfactant which is the salt of the amine of the formula:
