Abstract: Zwitterionic surfactant compounds are made readily biodegradable in the environment by the inclusion of a biochemically and/or hydrolytically labile chemical linkage located between the cationic and anionic charge centers of the compounds and anywhere from the second to the tenth atom distant from the cationic charge center. The biodegradable linkage is preferably an ester or amide. The alkoxylated zwitterionic surfactants herein exhibit outstanding particulate soil removal performance and are also effective in removing oily soils from fabrics, in addition to being readily biodegradable. Also described are detergent compositions containing the zwitterionic surfactants, and, optionally containing cosurfactants and detergent builders.

Abstract: A modified nickel catalyst used for stereo-differentiating reduction of carbonyl compounds is provided. The modified nickel catalyst is prepared by soaking a nickel catalyst in an aqueous modifying medium having dissolved therein at least one inorganic salt, such as sodium bromide or sodium chloride, and at least one optically active substance, such as optically active hydroxy acid. The modified nickel catalyst exhibits enhanced activity for stereo-differentiating reduction and causes little or no side reactions, and thus, brings about an extremely high yield of the reaction product.
