    Abstract: Thermosetting powdered coating compositions comprising (a) a high Acid Value carboxylic acid functional polyester resin having an Acid Value of at least 100 mg KOH/g and a functionality of at least 4.5, (b) a low Acid Value carboxylic acid functional polyester resin having an Acid Value of 20 to 50 mg KOH/g and a functionality of about 2.5 or less, and (c) a cross-linking agent. The high Acid Value polyester resin is the reaction product of a polycarboxylic acid or its anhydride reacted with a polyester polyol obtained from reacting 0 mol % to 100 mol % of isophthalic acid and/or 0 to 100 mol % terephthalic acid, or a mixture thereof, with a polyol mixture comprising at least one diol and at least one polyol having at least three hydroxyl groups. The thermosetting powdered coating compositions provide coatings with low gloss levels that can be adjusted from a gloss level of less than 1 to 40 or less, when measured at an angle of 60°, by varying the ratios of the high Acid Value and low Acid Value polyester resins in the composition.

    Abstract: Synergistic surfactant blends are disclosed. In one aspect, the blend comprises an anionic surfactant and a metathesis-based cationic surfactant comprising a quaternized derivative. The quaternized derivative is a quaternized fatty amine, quaternized fatty amidoamine, imidazoline quat, or esteramine quat made from a metathesis-derived C10-C17 monounsaturated acid or its ester derivative. Also disclosed are synergistic surfactant blends comprising a cationic surfactant and a metathesis-based anionic surfactant comprising a sulfonated derivative. The sulfonated derivative is a fatty ester sulfonate, fatty acid sulfonate, sulfoestolide, fatty amide sulfonate, sulfonated fatty ester alkoxylate, imidazoline quat sulfonate, sulfonated amidoamine oxide, or sulfonated amidoamine betaine. The synergistic blends have a negative β value or a reduced interfacial tension (IFT) when compared with an expected IFT value calculated from the individual surfactant components. Blends of the invention also exhibit surprisingly favorable solubility profiles. The surfactant blends are useful for laundry detergents, dish detergents, household or industrial cleaners, personal care products, agricultural products, building materials, oil recovery compositions, emulsion polymers, and other practical applications.

    Abstract: Surfactant compositions useful for oil recovery are disclosed. The compositions comprise from 10 to 80 wt. % of a propoxylated C12-C20 alcohol sulfate, from 10 to 80 wt. % of a C12-C20 internal olefin sulfonate, and from 0.1 to 10 wt. % of an ethoxylated C4-C12 alcohol sulfate. Surprisingly, including a minor proportion of the ethoxylated alcohol sulfate reduces or eliminates the need to rely on costly cosolvents for achieving good performance in enhanced oil recovery processes. In particular, low interfacial tensions and low microemulsion viscosities can be achieved when the ethoxylated alcohol sulfate accompanies the propoxylated alcohol sulfate and internal olefin sulfonate. Aqueous concentrates comprising water and the surfactant compositions described above are also disclosed. Dilution of the surfactant composition or aqueous concentrate with water or brine to the desired anionic actives level provides an injectable composition useful for EOR applications. Stable, low-viscosity oil-in-water microemulsions comprising crude oil, water, and the surfactant compositions are also disclosed.
