Abstract: Asphalt-based coating compositions and surfactants. The asphalt-based coating compositions have improved performance and comprise asphalt, clay, and a propoxylated alcohol-based ether amine salt surfactant.

Abstract: Viscoelastic surfactants are described for use in aqueous systems to generate thickened fluids. The surfactants are alkyl amidoamine salts of inorganic acids and/or organic acids. The fluids may also contain inorganic salts, organic salts or mixtures thereof. Additionally, the fluids may contain a co-surfactant. These fluids are particularly useful in oilfield applications such as hydraulic fracturing, gravel packing, drilling, completion, etc. Viscoelastic fluids of the invention are also useful in industrial and consumer product fluid applications as rheology control agents.

Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.

Abstract: The disclosure is directed to novel detergent compositions having polyalkoxylated amine foam stabilizers. The new foam stabilizers of the inventive detergent compositions build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.

Abstract: This invention is directed to an improved method for removing hydrocarbon-containing soils. The invention consists of preparing a detergent composition and applying the composition to the surface to be cleaned. Broadly, the detergent composition consists of from 1 to 99% by weight of at least one polyalkoxylated amine and from 99-1% by weight of at least one water-soluble surfactant. Other constituents may be added to enhance performance. The invention has desirable foamability characteristics.

Abstract: The disclosure involves a novel amine ether acid salt surfactant. The amine constituent of the surfactant may include ether amines or fatty-based amines. The ether acid constituent of the surfactant, in particular, imparts liquidity to the surfactant. Hydrophobic regions may be included on both the amine and ether acid enhancing the surfactancy of the composition. The novel surfactant is versatile and is useful in many different applications.

Abstract: An improved compound for use as a spray wax and drying aid in automatic vehicle-washing devices. The invention includes an olefin constituent having the general structural formula: ##STR1## wherein R.sub.1 is an alkyl group having between 4 to 28 carbon atoms and a first emulsifier having a cationic constituent. Certain preferred embodiments include a second emulsifier and a coupling agent.

Abstract: An improved asphalt roof-coating composition which includes asphalt, clay, and a novel hindered acid/amine salt surfactant. The surfactant comprises an acid constituent which has at least two alkyl groups bonded to the alpha carbon and an amine constituent comprising a variety of primary, secondary and tertiary amines. The composition has excellent physical properties including good viscosity and gel stability.

Abstract: The disclosure is directed to polyalkoxylated amines used as foam stabilizers and a method for cleaning in which foam produced by a detergent composition is maintained for an extended period of time. Detergent compositions including the new foam stabilizers are also disclosed as are methods for detergent foam stabilization. The new foam stabilizers build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.

Abstract: An improved asphalt roof-coating composition which includes asphalt cutback, clay, and a novel salt surfactant. The surfactant comprises an acid and alkoxylated fatty amines and alkoxylated ether amines. The novel surfactant amines are inexpensive and impart desirable physical properties to the composition.

Abstract: The disclosure involves an improved asphalt roof-coating composition which includes asphalt, clay, and a novel ether amine-acid-complex surfactant. The surfactant comprises an alkyloxyalkylamine, preferably having an alkyl chain with from 8 to 20 carbon atoms and an acid present in an amount in excess of the amount required to neutralize the amine. The composition is less expensive than prior art formulations and has improved viscosity and gel stability.

Abstract: This invention relates to apatite flotation reagents which can be used simultaneously with silica collectors in a coflotation process without problems of incompatibility between the apatite flotation reagent and the silica collectors. The apatite flotation reagent includes soya lecithin. The soya lecithin can be used as an apatite collector by itself or can be blended with a phosphate ester, preferably an ethylene oxide modified alcohol based phosphate ester. In an additional embodiment, the apatite flotation reagent can be solely comprised of a phosphate ester, preferably an ethylene oxide modified alcohol based phosphate ester.
