A two-part formulation derived from water based solutions having the ability to micro encapsulate low polarity hazardous hydrocarbons, organic chemicals, asbestos fiber, inorganic and/or chemical metals. The first solution includes water; a water soluble alkaline silicate solution having: at least one alkali metal; at least one water soluble anionic surfactant; at least one water soluble non-ionic surfactant; a least one medium molecular weight polystyrene triblock copolymer fluff; and at least one low molecular weight liquid polybutene plasticizing entity. The second solution includes water and a water soluble acid; a water dispersible polymer; a water soluble hydrotrope at least one water soluble flocculating agent. The formulation may be employed in a method that includes applying the first foaming solution to a surface containing hazardous material; allowing the first foaming solution to contact the hazardous material to penetrate the hazardous material; applying the second solution to the surface, and allowing the second solution to contact the first solution and hazardous material to form a homogeneous mixture.

A two-component, water based micro encapsulation composition and method for the cleanup of hydrocarbon spills or contaminates on various surfaces and media. The two-part formulation includes a first solution including water in a predetermined ratio of a water soluble alkaline silicate solution having at least one alkali metal and a predetermined ratio of at least one water soluble surfactant; and a second solution including water, a predetermined ratio of water soluble acid, a predetermined ratio of water dispersible polymer, a predetermined ratio of water soluble hydrotrope, and a predetermined ratio of at least one water soluble flocculating agent. A method of using the two-part formulation includes preparing the two-part formulation, allowing the first solution to contact the hydrocarbon or chemical contaminate; allowing the second solution to contact the first solution and contaminate to form a homogeneous mixture; and removing the homogeneous mixture.

Abrégé

The present invention relates to methods of recovering hydrocarbons or low polarity organic chemicals from hard surfaces, water and water surfaces, in their vapor state and from porous substrates. The hydrocarbons or low-polarity organic chemicals may be included in a spill. More particularly, the invention relates to the absorption of certain hydrocarbons and low-polarity organic chemicals by applying thermoplastic elastomers of a triblock copolymer of the general configuration A-B-A. The preferred A-B-A copolymer of the invention is a low to medium molecular weight hydrogenated polystyrene-poly(isoprene+butadiene)-polystyrene or polystyrene-b-ethylene/ethylene-propylene-b-styrene block copolymer. The method of forming a three-dimensional object from a hydrocarbon or low-polarity organic chemical absorbing substance includes: applying pressure to particles of a polymeric material comprising a styrene-ethylene/ethylene/propylene triblock copolymer containing from approximately 20 to 40 percent styrene, and; heating the particles for a period of time sufficient to form the three-dimensional object.

When the elastomeric block copolymer is applied to the hydrocarbon or low-polarity organic chemical, the elastomeric block copolymer absorbs the hydrocarbons or low-polarity organic chemicals to form a mat.
