    Abstract: The present invention relates to an improved method for making sulfonated block copolymers and to methods for making membranes from such block copolymers. In particular, the present invention relates to an improved method for making sulfonated block copolymers having at least two polymer end blocks that are resistant to sulfonation and at least one polymer interior block that is susceptible to sulfonation where the sulfonation agent is C 2 to C 8 acyl sulfate. In the improved process the residual carboxylic acid formed from the C 2 to C 8 acyl sulfate is converted to C 1 to C 4 alkyl esters by contacting the residual carboxylic acid with at least a 0.9: 1 molar ratio of a C 1 to C 4 alcohol to residual carboxylic acid, resulting in an improved sulfonated block copolymer solution. The present invention further relates to the use of such sulfonated block copolymer solutions to prepare various membranes and other articles.

    Abstract: The presently described technology relates to acyl lactylate containing compositions having improved stability and multifunctional performance characteristics (e.g., pH stability, phase stability, hydrolytic stability (e.g., aqueous stability), cleansing, foaming, skin softness and skin moisturization) that may be utilized in rinse-out and leave-on skin and hair applications. The acyl lactylate compositions of the present technology may be delivered to the skin or hair via a conventional delivery vehicle such as a body wash, a shampoo, a bubble bath, a skin cream, or a lotion.

    Abstract: Liquid cleaning compositions are described that comprise sulfo-estolide (SE) salts, particular sodium, lithium or ammonium salts of sulfo-estolides, and alkyl ester sulfonates. The liquid cleaning compositions are clear, stable and substantially free of precipitates due to the use of sodium, lithium or ammonium salts of sulfo-estolide rather than a potassium sulfo-estolide salt in the composition. The liquid cleaning compositions also have a total combined amount of saturated C16 and C18 fatty acids of less than about 5% by weight to prevent the formation of precipitates in the composition.

    Abstract translation: 描述了包含磺基 - 内酯醇（SE）盐，磺基甲基酯的特定钠，锂或铵盐和烷基酯磺酸盐的液体清洁组合物。 液体清洗组合物由于在组合物中使用磺基 - 甲基内酯钠的钠盐，锂盐或铵盐而不是磺基磺酸钾钾盐，所以清洁，稳定并且基本上不含沉淀物。 液体清洁组合物还具有小于约5重量％的饱和C 16和C 18脂肪酸的总组合量，以防止组合物中沉淀物的形成。
