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: Provided are alkyl lactyllactate compositions that can be prepared from (1) lactide or alternatively lactic acid, and (2) a hydroxyl containing compound such as an alcohol, preferably a fatty alcohol or an alkoxylated alcohol, with (3) an acid catalyst. Preferably, the fatty alcohol contains from about 6 to 18 carbon atoms, such as lauryl alcohol. The alkyl lactyllactates can be used as surfactants, emulsifiers, skin feel agents, film formers, thickeners, rheological modifiers, etc., for personal care and other application areas. Compositions containing at least one alkyl lactyllactate are also provided. The compositions can further contain at least one surfactant.

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.
