Abstract: Disclosed are hair care compositions and methods for preparing such compositions which provide the benefits of cleaning, conditioning, curl retention, styling and setting properties simultaneously to hair in the application of a single product. The hair care compositions contain fatty alkyl amine salts, long chain quaternary ammonium salts and mixtures thereof of anionic styling polymers in a non-anionic surfactant system, wherein the surfactant system contains nonionic surfactants, semi-polar nonionic surfactants, amphoteric surfactants and mixtures thereof. The styling, setting and conditioning agents are present in the form of fatty alkyl amine salts or fatty quaternary ammonium salts which form anionic styling polymer particulate networks upon dilution in water. These networks are dispersed in the aqueous non-anionic surfactant system and are stabilized and thickened by optional swellable polymer thickening agents. Hair care compositions of the present invention can be made in the form of structured liquids, pearlescent/opaque isotropic liquid and/or translucent/clear isotropic liquids. The hair care compositions of the present invention, which allow for re-styling of the hair by wetting the hair with water, contain no anionic surfactants, silicones, solvents or cationic polymeric conditioning agents. Furthermore, multiple application of these hair care compositions does not produce a noticeable build-up on the hair.

Abstract: A method of mitigating the formation of 1,4-dioxane and precursors of 1,4-dioxane in alkyl ether sulfate surfactants is disclosed. The method involves adding one or more alcohol, hydrotrope or anti-oxidant additives to an aqueous solution of alkyl ether sulfate surfactant having at least two ethylene oxide groups. The alcohol, hydrotrope, or anti-oxidant is added to the alkyl ether sulfate solution in an amount effective to reduce the formation of diethylene glycol monosulfate, a precursor of 1,4-dioxane, and also reduce the formation of 1,4-dioxane.

Abstract: A hydraulic fracturing method is disclosed. A small proportion of a nonionic surfactant is used in combination with an acrylamide polymer emulsion friction reducer, the proppant, and the base water to boost the viscosity of the fracturing fluid. The nonionic surfactant has a calculated HLB within the range of 10 to 17. The nonionic surfactants include selected aralkylated phenol ethoxylates, amine or amidoamine ethoxylates, mixed EO/PO alcohol alkoxylates, ethoxylated alcohols, ethoxylated amides, and alkylphenol ethoxylates. The nonionic surfactant boosts the viscosity of the fracturing fluid, promotes proppant transfer, and enables more-efficient hydrocarbon production.

Abstract: Blends comprising an aromatic polyester polyol and a 1 to 10 wt. % of a fatty acid derivative are disclosed. The fatty acid derivative is a C8 to C18 fatty acid ester or a C8 to C18 fatty acid amide. Also disclosed are rigid PU or PU-PIR foams that comprise a reaction product of water, a catalyst, a foam-stabilizing surfactant, a polyisocyanate, a blowing agent, and the polyester polyol/fatty acid derivative blends. Surprisingly, low-temperature R-values of rigid foams based on pentane blowing agents can be improved significantly by using blends of aromatic polyester polyols and a minor proportion of readily available fatty acid derivatives. In some aspects, the difference between initial R-values of the foam measured at 75° F. and 40° F. is at least 5% greater than that of a similar foam prepared in the absence of the fatty acid derivative.

Abstract: Dilutable concentrates useful for hard surface cleaners with improved film/streak performance on high-energy surfaces are disclosed. The concentrates comprise a nonionic alkoxylated surfactant and a polyetheramine. A relatively minor proportion of a polyetheramine can resolve film/streak issues that characterize hard surface cleaners formulated with nonionic surfactants. The efficacy of polyetheramines for improving film/streak performance of hard surface cleaners formulated with nonionic alkoxylated surfactants far exceeds the benefits available from known improvements, such as the use of hydrotropes. Other inventive dilutable concentrates and hard surface cleaners comprise an amine-functional hydrophobe and an auxiliary surfactant. Still other dilutable concentrates or hard surface cleaners comprise a nonionic alkoxylated surfactant and lactic acid. An improved method for measuring film/streak properties of hard surface cleaners is also disclosed.

Abstract: A method of degrading 1,4-dioxane in the wastewater produced during the manufacture of alkyl ether sulfates is disclosed. The method includes the steps of (a) mixing from 100 to 10,000 ppm, preferably 1,000 to 4,000 ppm of ozone with the wastewater; (b) introducing H2O2 into the wastewater in an amount of 0.01 to 10, preferably 0.1 to 0.5 molar equivalents of H2O2 to ozone, and (c) mixing the ozone, H2O2, and wastewater to generate hydroxyl radicals reactive with the 1,4-dioxane, without the addition of a metal catalyst. The hydroxyl radicals react with the 1,4-dioxane and degrade it into carbon dioxide, water and/or carbonate. The method is effective to reduce a concentration of 1,4-dioxane in the wastewater from a range of about 10 ppm to about 1000 ppm of dioxane down to less than 5 ppb of 1,4-dioxane after treatment. The method is also effective for removing hydrocarbon species that may be present in the wastewater.

Abstract: Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed. The derivatives and sulfate compositions are valuable for many end-use applications, including, for example, agricultural dispersants, water-soluble herbicides, anionic emulsifiers for agricultural use, hard surface cleaners, light-duty liquid detergents, personal cleansers, gas well foamers for oilfield applications, laundry detergents, enhanced oil recovery compositions, latex paints, and specialty foams.
