A process for selectively preparing an unsaturated long-chain aliphatic secondary amine at a high yield comprising reducing an unsaturated aliphatic nitrile having 8 to 22 carbon atoms or a nitrile mixture containing said nitrile with hydrogen in the presence of a Ni hydrogenation catalyst and a carboxylic acid amide at a reaction temperature of 160.degree. C. to 200.degree. C.

Process for preparation of unsaturated long-chain aliphatic secondary

Enzyme-containing detergent compositions containing, as essential ingredients, .alpha.-olefin sulfonates having 10 to 20 carbon atoms, polyethylene glycols having a weight-average molecular weight of 1,000 to 20,000 and enzymes are presented. These enzyme-containing detergent compositions do not cause the decrease in foaming property when objects being washed are previously soaked in an aqueous solution of the enzyme-containing detergent composition.
