【Task】 The present invention relates to a method for masking odor notes of oleochemical preparations by adding a lactone of formula (la) or (lb). Where R 1 is a linear or branched, saturated or unsaturated, optionally hydroxy-substituted hydrocarbon group having 2 to 22 carbon atoms and 0 or 1 to 1 double bonds, n Is 1 or 2. The lactones of formula (I) can not only mask unpleasant odor notes, even in small amounts, especially in the majority of oleochemical preparations that have a greasey odor or nose odor, but also enhance the odor notes Is possible. |
