the Tagetes picture.
Uses in Perfume
The ester has found a little use in perfume
compositions, mainly for fantasy notes, new
variations of "powdery" notes, etc., and in
certain types of "tabac" fragrances, with
proper support of Clary sage and Linalyl- ogcertain "Carbinyl"-esters it can supply a Tealike effect of some interest.
