This invention relates to a “high lower alcohol content” (>40% v / v of a C1-4 alcohol) liquid composition able to be either dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers or as an alcohol gel composition which does not use thickener and gelling agents that leave undesirable deposits or a sticky after-feel and that has a final viscosity less than 4,000 cps. The liquid compositions comprise an alcohol, C1-4 (>40% v / v), a fluorosurfactant of at least 0.001% by weight to prepare a foamable composition or from 0-2.0% to prepare a gel-like composition of a final viscosity less than 4,000 cps, 0-10% w / w of additional minor components added to obtain the desired performance (a foamable composition or a gel-like composition with a viscosity less than 4,000 cps), and the balance being purified water. The compositions may include emulsifier-emollients and mosturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.

The present invention relates to associative complexes of water soluble and / or water dispersible polymers and polymeric fluorosurfactants, compositions and methods for modifying substrates to provide treated articles with surface protective properties including easier cleaning, increased stain and / or soil repellency, and increased resistance to bio-fouling and environmental contamination.

A rinse agent composition is provided. The rinse agent composition includes a sheeting agent for promoting draining of sheets of water from a surface, and a humectant. The humectant is a component which retains at least 5 wt.% water when the humectant has been contained at an equilibrium of 50% relative humidity and room temperature. The sheeting agent and humectant are preferably provided at a ratio of between about 5:1 and about 1:3. A method for rinsing a substrate surface in the presence of high solids containing water is provided. High solids containing water is generally considered to be water having a total dissolved solids content in excess of 200 ppm.

Described are fluorochemical surfactants derived from nonafluorobutanesulfonyl fluoride that contain polyalkyleneoxy side chains and may be copolymerized with acrylic acid or methacrylic acid to form polyacrylates or polymethacrylates. The surfactants surprisingly lower the surface tension of water and other liquids in the same or similar low values achieved by premier surfactants such as those derived from perfluorooctane sulfonyl fluoride.

This invention is directed to a composition capable of imparting surface effects to a liquid by contacting the liquid with a partially fluorinated phosphate with an ammonium cation (NH2R1R2)+ wherein R1 and R2 are independently linear or branched organic groups containing at least one carboxylate moiety and one amino moiety, and optionally be substituted, interrupted, or both with oxygen, sulfur, or nitrogen-containing moieties, or with cyclic alkyl or aryl moieties containing up to 10 carbon atoms.

Compositions and methods employing supercritical fluids, e.g., supercritical carbon dioxide, for removal of unwanted material from microelectronic device structures and process equipment. One composition of such type, having utility for removing flux and solder perform surface films, includes supercritical fluid, e.g., supercritical CO2, and organic co-solvent, e.g., xylene. Another composition of such type having utility for removal of metals, metal oxides, metal-containing post-etch residues and CMP particles from semiconductor substrates includes supercritical fluid and at least one β-diketone.

This invention relates to compositions containing lower (C1-C4) alcohol and a polymeric fluorosurfactant formulated for being dispensed as a foam product. More particularly, the invention relates to improved compositions formulated with polymeric fluorosurfactants with pendant perfluoroalkyl side chains of a fully fluorinated chain length of C1-C7. The compositions also relate to use for personal care, such as skin sanitizing and cleansing.

The invention provides solvent and cleaning compositions comprising an ionic surfactant, which preferably has a fluorinated portion thereof, and a solvent selected from hydrofluoro- and / or hydrochlorofluoro-olefins. Additionally, the invention provides drying, dry cleaning, and soil repellency compositions containing a hydrofluoro- or hydrochlorofluoro-olefin and said surfactant. Additionally, the invention provides drying compositions containing a hydrofluoro-olefin or hydrochlorofluoro-olefin and an alcohol such as methanol, ethanol or isopropanol.
