  Vesicles and other supramolecular systems from biocompatible synthetic glycolipids with hydrocarbon and/or fluorocarbon chains

  摘要：

  A series of double-tailed hydrocarbon and/or fluorocarbon glycolipids derived from galactose and glucose have been prepared. These compounds were obtained upon opening a lactono- and maltonolactone moiety by the amino group of either a glycine, glycylglycine or lysine residue. The carboxyl terminus of the glycyl and glycylglycine conjugates was further reacted with the appropriate double-tailed amine. In the case of lysine, the lactonamide conjugate was functionalized with a hydrocarbon and/or fluorocarbon fatty amine and acid, respectively. The ability of such glycolipids to disperse in water, the morphology of self-assemblies formed and the stability of the supramolecular structure obtained were shown to depend on the presence or absence and on the nature of the aminoacid spacer. Most of the compounds described were shown by conventional techniques (TEM, Cryo-TEM, LLS, etc.) to produce stable vesicular systems.

  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.

  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.
