  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.

  本发明公开了可用于冷水清洁的洗涤剂以及可用于冷水清洁的中链头基表面活性剂和亚烷基桥接表面活性剂。中链头表面活性剂具有 C14-C30 烷基链和一个与烷基链中心区碳键合的极性基团。烯桥表面活性剂具有 C12-C18 烷基链、一个极性基团以及一个与极性基团和 C12-C18 烷基链中心区碳键合的 C1-C2 烯基。这几类表面活性剂中较好的有醇硫酸盐、醇聚氧乙烯醚、醚硫酸盐、磺酸盐、芳基磺酸盐、醇磷酸盐、氧化胺、季铵盐、甜菜碱和磺基甜菜碱。令人惊奇的是，使用这些表面活性剂配制的洗涤剂在去除脏污物品上的油渍（如培根油、黄油、熟牛肉脂肪或牛脂）方面具有出色的冷水性能。

  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.

  本发明公开了用于冷水清洗的洗衣剂及其用途。洗涤剂由脂肪酶和中链头表面活性剂或亚烷基桥接表面活性剂组成。中链头表面活性剂具有 C14-C30 烷基链和与 C14-C30 烷基链中心区碳键合的极性基团。烯键表面活性剂包括一个 C12-C18 烷基链、一个极性基团以及一个与极性基团和 C12-C18 烷基链中心区碳键合的 C1-C2 烯基。令人惊奇的是，当与脂肪酶结合使用时，用中链头基团或亚烷基桥接表面活性剂配制的洗涤剂可在低温下有效地液化油脂污垢，并在冷水条件下具有出色的去污性能，可去除脏污物品上的油脂污渍，如培根油、黄油、熟牛肉脂肪或牛脂。
