| 20080200351 | Method of recycling fracturing fluids using a self-degrading foaming composition - A method of fracturing a subterranean zone penetrated by a well bore preparing a foamed fracturing fluid containing a self-degrading foaming composition with a mixture of anionic surfactant and nonionic surfactant, and a composition thereof. The fracturing fluid containing self-degrading foaming composition forms a substantially less stable foam when the foamed fracturing fluid is recovered during reclaim. | 08-21-2008 |
| 20090013481 | COMPOSITION TO IMPART BENEFIT AGENTS TO ANIONIC SUBSTRATES AND METHODS OF ITS USE - This invention relates to compositions containing pigments or other benefit agents in particulate form may be combined with a quaternary ammonium compound that can effectuate adsorption to anionic substrates, methods of making such compositions and methods of their use. | 01-15-2009 |
| 20090016975 | FADE-RESISTANT COLORING COMPOSITION CONTAINING AN ACID DYE AND A CATIONIC CONDITIONING AGENT FOR A KERATIN-CONTAINING SUBSTRATE - The invention relates to a coloring composition for depositing colors to a keratin-containing substrate, said composition comprising: (a) one or more acid dyes; and (b) one or more cationic quaternary ammonium compounds, said quaternary ammonium compound being present in an amount which provides conditioning benefits but which is insufficient to interfere with deposition of said dye on said substrate. | 01-15-2009 |
| 20100216674 | MULTICOMPONENT VISCOELASTIC SURFACTANT FLUID AND METHOD OF USING AS A FRACTURING FLUID - There is a viscoelastic fluid. The fluid has one or more cationic surfactants selected from the group consisting of certain quaternary salts, certain amines, and combinations thereof; one or more anionic polymers/anionic surfactants; one or more of certain zwitterionic/amphoteric surfactants; and water. There is also a method of fracturing a subterranean formation. The viscoelastic fluid is pumped through a wellbore and into a subterranean formation at a pressure sufficient to fracture the formation. There is also a method for gravel packing a subterranean formation. | 08-26-2010 |
| 20100255044 | METHOD OF DEPOSITING PARTICULATE BENEFIT AGENTS ON KERATIN-CONTAINING SUBSTRATES - This invention relates to the deposition of particulate benefit agents onto keratin-containing substrates such that the deposited particulates are resistant to removal by exposure to surfactants or cleansing agents. The deposition is accomplished by sequentially treating the substrate with a cationic composition followed by treatment with an anionic particulate benefit agent. | 10-07-2010 |

| 20090163389 | Scale squeeze treatment systems and methods - An aqueous composition for treating hydrocarbon wells contains (a) a scale inhibitor and (b) a viscoelastic surfactant, and further contains from 0 to less than 1% by weight of acid selected from the group consisting of hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, citric acid, maleic acid, hydrofluoric acid, and mixtures thereof. | 06-25-2009 |
| 20110143972 | Scale squeeze treatment systems and methods - An aqueous composition for treating hydrocarbon wells contains (a) a scale inhibitor and (b) a viscoelastic surfactant, and further contains from 0 to less than 1% by weight of acid selected from the group consisting of hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, citric acid, maleic acid, hydrofluoric acid, and mixtures thereof. | 06-16-2011 |
