Abstract: Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the C14-C30 alkyl chain. The alkylene-bridged surfactants comprise a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

Abstract: Detergents useful for cold-water cleaning and mid-chain headgroup and alkylene-bridged surfactants useful therein are disclosed. The mid-chain headgroup surfactant has a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Preferred surfactants in these classes are alcohol sulfates, alcohol ethoxylates, ether sulfates, sulfonates, arylsulfonates, alcohol phosphates, amine oxides, quaterniums, betaines, and sulfobetaines. Surprisingly, detergents formulated with the surfactants provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

Abstract: Polyester-epoxide polymer (PEEP) compositions are disclosed. The PEEP compositions comprise a reaction product of a polyepoxide compound (eq. wt. 125 to 250 g/eq.) and a polyester polyol composition. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.8 to 3.5. The PEEP composition has a Tg within the range of −40° C. to 60° C. Elevated temperature-cure and low temperature-cure processes for making the PEEP compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for adhesives, coatings, elastomers, and other valuable products is assembled from readily available starting materials without reliance on polyisocyanates or polyamines. The PEEP compositions have increased elongation and lower Tg when compared with traditional epoxy products.

Abstract: Methods for enhanced oil recovery are disclosed. In one method, an oil-bearing sandstone formation having a clay content of at least 5 wt. % is injected with a surfactant mixture, a solution comprising 0.5 to 3 wt. % aqueous alkali, and an aqueous solution comprising a polyether. In another method, a sandstone formation having a salinity within the range of 20,000 to 100,000 ppm total dissolved solids and a divalent ion content within the range of 1,000 to 10,000 ppm is injected with a surfactant mixture and an aqueous solution comprising a polyether. In both methods, the polyether solution is injected as a sacrificial agent prior to injection of the surfactant mixture or is injected as a mitigation agent concurrently with the surfactant mixture. Surprisingly, adsorption of the surfactant mixture onto the formation can be reduced by 20-70% or more compared with a similar methods performed without the aqueous alkali solution, the polyether solution, or both.

Abstract: Disclosed are the use of novel surfactants for the synthesis of emulsion polymer latexes, particularly those used in paints, coatings, and pressure sensitive adhesives. The surfactant compositions for emulsion polymer latexes comprise sterically bulky surfactants whose composition comprises at least one alkoxylated polyaryl substituted aromatic sulfosuccinate compound. The novel surfactants provide for the production of stable, small particle size distribution emulsion polymer latexes. The resulting latexes, when formulated into latex paint, impart improvements in water resistance as measured by film opacity, blister resistance and improved leveling characteristics, and when formulated into pressure sensitive adhesives, provide improved water resistance characteristics as measured by film opacity.

Abstract: Personal cleansers and surfactant blends useful therein are disclosed. The cleansers comprise a primary anionic surfactant, a saturated C8-C-14 alkyl N,N-dialkylamide, and water. The cleansers have good foaming properties and improved viscosity build profiles compared with cleansers that rely on alkanolamides or betaines as the secondary surfactant. The saturated C8-C14 alkyl N,N-dialkylamides are water-white liquids that solubilize cleanser components well, including high levels of fragrances, and can be formulated easily without heating at any actives level up to 100%. Importantly, the surfactant blends build viscosity with less added salt compared with alkanolamide or betaine-based blends, even with more challenging anionic surfactants. Moisturizing cleansers disclosed herein have excellent flash foaming character, foam volume, and foam feel and provide a luxurious, lotion-like after-feel. The personal cleansers include, among others, shampoos, body washes, facial cleansers, shower gels, liquid soaps, hand soaps, baby liquid cleansers, pet shampoos, and bubble baths. The fatty N,N-dialkylamides are also valuable for formulating oil-in-water emulsions with good stability.

Abstract: Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C10-C12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

Abstract: A fabric conditioning active composition comprising an esterquat mixture of quaternized mono-, di-, and tri-esters of alkanolamine in which the tri-esterquat content of the quaternized esterquat mixture is greater than 25% by weight of the esterquat mixture, and the combined di-esterquat and tri-esterquat content in the esterquat mixture is greater than 78% by weight of the esterquat mixture. Additionally, the free fatty acid content of the composition is greater than 1% by weight based on the weight of the esterquat mixture. The fabric conditioning active composition provides high viscosity when dispersed into water at low concentrations of 0.5% to 12%, without the need for additional polymeric thickeners or other thickening additives.
