Abstract: The present invention relates to super mild surfactant systems used in combination with skin or hair benefit agent(s). Specifically, surfactant systems comprise a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product to provide synergy which reduces irritation (as measured by Patch Testing) so greatly that it is comparable to mildness which normally can be only achieved using very great amounts of benefit agent (e.g., emollient). Use of benefit agent reduces irritation even further.

Abstract: Compositions to deposit an active substance on a target surface (i.e. fabric, sun, hair, teeth). The active substance is left on the surface, after the product is rinsed off the surface. The preferred deposition is from compositions containing an anionic or nonionic active in the co-presence of an anionic surfactant. The compositions contain carrier particles having a zwitterionic or cationic surface and a plurality of outwardly protruding filaments containing charged organocarbyl groups. The active substance is contained within the carrier particles.

Abstract: An environmentally safe method is provided for the removal and disposal of residual water soluble polymers, particularly polyethers, from aqueous waste streams, wherein a pretreated inert inorganic substrate is contacted with the waste stream and the polymer contained therein adsorbed onto the substrate. Thereafter, the polymers are removed from the substrate as CO.sub.2 and water by combustion and the substrate subjected to regenerative conditions for recycling.

Abstract: A process for the selective concentration of metal values in solution wherein said metal-containing solution is contacted with a multiple-phase system having a common solvent, thereby causing the preferential migration of metal values into one phase of said multiple-phase system. The phases of the system may then be isolated and the metal values recovered therefrom by conventional techniques.

Abstract: A process for the recovery of enzymes from an aqueous system having at least two aqueous phases wherein the partition coefficient with respect to an enzyme may be improved through the addition of organo-compatible, compounds having anionic functionality, such as polyacrylic acid, polyvinyl sulfonate and sodium dodecylsulfate.

Abstract: A method is provided for increasing the solubility of an enzyme in an aqueous solution comprising providing a water-soluble anionic surfactant to the solution and further providing the solution with a pH above that which result in the formation of an enzyme/surfactant precipitate. The application is further directed to an aqueous solution containing an anionic surfactant and having an enzyme concentration contained therein which is higher than that possible in the absence of the surfactant.

Abstract: This invention relates to a process for the separation and recovery of particulate matter having an average diameter of about 1 micron or less through the use of aqueous hi-phase systems and the modification of the surface properties of the particulate matter through use of a surfactant to modify its tendency to selectively migrate to one phase of the bi-phase system.

Abstract: A method is disclosed for the recovery of biological material from an aqueous solution comprising contacting a water-insoluble, particulate binder with a solution containing biological material to produce a water insoluble biological material/binder composition which may then be recovered. The aqueous solutions may then be recycled.

Abstract: The present invention is directed to silicon carbide whisker recovery from a mixture of silicon carbide whiskers and carbonaceous silicon carbide particles. The invention involves shredding the mixture down to a specified size, dispersing the mixture in water to form an aqueous mixture, mixing in an effective amount of flocculating agent, agitating the aqueous mixture, mixing the aqueous mixture with an immiscible organic liquid, agitating the resulting water-organic liquid mixture, allowing settling of the aqueous mixture and organic liquid so as to establish two liquid phases, separating the two liquid phases into an organic liquid phase and an aqueous phase and, lastly, performing a solid-liquid separation on the aqueous phase, thereby obtaining from the aqueous phase the desired silicon carbide whiskers.
