The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of &#x2267;0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of &#x2266;0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.

The present invention generally relates to a process for preparing the alkoxylated alkylamines and/or alkyl ether amines. The process consists of three stages, and utilizes an alkali catalyst. The alkoxylated alkyl amines and alkoxylated alkyl ether amines prepared by the process possess the peaked distribution and contain less hazardous by-product.

The present invention generally relates to a method and a composition useful in restoring the permeability of a porous underground petroleum containing formation. Restoring permeability to the formation enhances the injectivity thereby accelerating petroleum recovery. The method of the invention comprises treating said formation with a composition which comprises a combination of at least one nonionic compound, preferably an alkoxylated alcohol, with at least one cationic compound, preferably a quaternary ammonium compound, in an amount effective to improve the permeability of the formation. The composition may also optionally contain an alkyl glycoside.
