Abstract: A method of slurrifying oil contaminated materials by introducing a microemulsion or microemulsion-forming surfactant(s) to the material and subjecting the mixture to suitable shear or mixing forces to suitably blend such mixtures. The method may be applied directly to wastes such as waste drill mud cuttings and muds, emulsions, sludges, or soil substrates contaminated with water and/or oil drilling fluids in order to both reduce the viscosity and improve the lubricity, wetting, and flow properties of the substrate.

Surface Active Solutions (Holdings) Limited
Abstract: Material in web form intended in particular for use in a diagnostic strip and composed of a carrier material coated on one or both sides with an ultrathin coating varnish comprising at least one anionic surfactant based on a sulphosuccinic ester salt, the ultrathin coating varnish having, after drying, a coating distribution of from 5 to 100 mg/m2.
Abstract: An emulsion is optimized in that it is stabilized by the presence of a surfactant specifically selected according to the type of a polymer, or copolymer, also present in the emulsion. The surfactant and the polymer are selected oppositely charged.
Abstract: Liquid concentrate components of a fountain solution are provided, including a liquid film-forming fountain solution concentrate and a liquid surface-tension reducing fountain solution concentrate. The concentrates and water can be combined together to form a fountain solution composition.
