Abstract: Aqueous hard surface cleaner compositions derived from metathesized natural oil feedstocks are disclosed. In one aspect, the compositions comprise at least one anionic surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, 5 octadecene-1,18-dioic acid, or their ester derivatives. In another aspect, aqueous hard surface cleaners comprising at least one nonionic or amphoteric surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives are disclosed. The aqueous cleaners noted above rival or outperform commercial baselines in a Gardner straight-line washability test. Industrial degreasers comprising a C10 or C12 amide solvent and derived from a metathesis-derived C10-C17 monounsaturated acid are superior to commercial standards.

Abstract: A process for producing powder, flakes, or pellets containing ?-sulfo fatty acid alkylester salt in high concentrations, the process including: (1) a step of preparing a paste containing ?-sulfo fatty acid alkylester salt; (2) a step of aging the thus obtained paste; (3) a step of making the aged paste into flakes or pellets containing equal to or less than 10 wt % of water and then optionally crushing the resulting flakes or pellets into a powder having an average particle diameter of 100-1500 ?m; and (4) a step of aging The powder, flakes, or pellets.
Abstract: The present invention provides a basic amino acid derivative represented by the formula (1): The present invention also provides a method of making a gelled product by employing the aforementioned compound, as well as a gel, perfumery, and/or cosmetic containing the same.
Abstract: A process for the purification and isolation of a chemical compound, by extractive solution crystallization. The process comprises combining in any order a first solvent, a second solvent, and a mixture comprising a chemical compound with at least one impurity. The second solvent phase extracts impurities out of the first solvent, and keeps the impurities dissolved to avoid their co-crystallization with the phenyl ester salt. Once the chemical compound has crystallized out of solution, it is collected, washed and/or dried. The second solvent may be added after the mixture containing at least one chemical compound is dissolved in a first solvent, as long as the second solvent phase is added prior to the end of crystallization. Advantageously, this invention combines the previously distinct steps of extraction and crystallization in one unit operation.

Abstract: The invention concerns amphiphilic compounds of general formula (I) ##STR1## with at least two hydrophilic and at least two hydrophobic groups based on diacarboxylic acid diamides. The amphiphilic compounds according to the invention are mostly surface-active and are suitable for use as emulsifiers, demulsifiers, detergents, dispergents and hydrotropic agents in industry and households, for example, in the treatment of metals, ore processing, surface finishing, washing, cleaning, cosmetics, medicine and food processing and preparation.
Abstract: A sulfated acid amide having heparin-like properties of the formula:(R.sub.1)--NH--R--NH--(R.sub.1)whereR.sub.1 is a di-, tri- or tetra-saccharide acid selected from cellobiose, cellotriose, cellotetrose, maltose, maltotriose and maltotetrose or mixtures thereof, andR is an alkylene of from 3 to 12 carbons, and is optionally substituted with one or more hydroxyls.
Abstract: It has been found that certain combinations of substituted imidazoline-based amphoterics and quaternary ammonium compounds show markedly reduced irritation profile in addition to providing excellent cleaning detergency. Moreover, it has further been found that certain substituted imidazoline amphoteric surfactants in combination with didecyl dimethyl ammonium chloride (DIDAC) show unexpected synergistic irritation reduction compared to that observed when the quaternary is an ADBAC type. This allows the formulation of disinfectants and sanitizers with the favored antimicrobial agent while at the same time affording the optimum reduction in irritation potential.

Abstract: A resinous binder for use in hot melt ink compositions, which ink compositions may be used in hot melt ink jet printing applications, is disclosed. The resinous binder has a melt viscosity of 250 cps or less at 150.degree. C., is sufficiently transparent to allow a colorant to be distributed through the resinous binder in an amount effective to impart a pre-determined color to the resulting hot melt ink composition, and has a blocking temperature greater than 100.degree.
