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 C-Calkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C-Calkyl chain, a polar group, and a C-Calkylene group bonded to the polar group and a central zone carbon of the C-Calkyl 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. 1. A detergent , useful for cold-water cleaning , comprising a mid-chain headgroup surfactant , wherein the surfactant has:{'sub': 14', '30, '(a) a saturated or unsaturated, linear or branched C-Calkyl chain; and'}{'sub': 14', '30, '(b) a polar group bonded to a central zone carbon of the C-Calkyl chain.'}2. The detergent of further comprising water.3. The detergent of wherein the mid-chain headgroup surfactant is selected from the group consisting of alcohol sulfates claim 1 , alcohol ethoxylates claim 1 , ether sulfates claim 1 , sulfonates claim 1 , arylsulfonates claim 1 , alcohol phosphates claim 1 , amine oxides claim 1 , quaterniums claim 1 , betaines claim 1 , sulfobetaines claim 1 , and mixtures thereof.4. The detergent of wherein the mid-chain headgroup surfactant is an alcohol sulfate.5. The detergent of wherein the mid-chain headgroup surfactant is a sulfate of a fatty alcohol selected from the group consisting of 7-tetradecanol claim 4 , 6-tetradecanol claim 4 , 5-tetradecanol claim 4 , 8-pentadecanol claim 4 , 7-pentadecanol claim 4 , 6-pentadecanol claim 4 , 5-pentadecanol claim 4 , 8-hexadecanol claim 4 , 7-hexadecanol claim 4 , 6- ...
