  • Surface-active agents
    Patent number: 5008383
    Abstract: Novel surface-active compositions are prepared by reacting a diketene prepared from a fatty acid or fatty acid chloride with 8-22 carbon atoms with a substance having a hydrophlic moiety and a hydroxyl or amino group containing one or more active hydrogens. The active hydrogen-containing group is acylated by the diketene and the resulting product contains the hydrophillic moiety and also branched 2-alkyl-3-ketoacyl chains.
