B. extracts of labdanum or styrax or certain abietic acid derivatives. Fragrance agents or perfume oils act as odor maskers and, in addition to their function as odor maskers, give the deodorants their respective fragrance.

Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and twigs as well as resins and balms. Animal raw materials, such as civet and castoreum, are also suitable. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type.
