Abstract (en)
[origin: WO9221738A1] The invention concerns the use, as odoriferous substances, of isomeric 1,1,1-trialkyl-2-phenylethane derivatives of general formula (I), in which R?1 to R?3, independently of each other, are alkyl groups with 1 to 3 C-atoms and R?4 is hydrogen or an alkyl, acyl, alkoxycarbonyl or alkoxyalkyl group with a total of 2 to 5 C-atoms. These compounds, in particular the 2,2-dimethyl-1-phenylpropyl ester of acetic acid, have a complex rosy/woody character and high scent-emanation power, and can be mixed with each other or with other odoriferous substances in widely varying proportions, generally 1-70 % by wt. relative to the overall composition, to give new fragrances. These compositions can be used for perfuming cosmetic preparations and industrial products, as well as in alcohol fragances.
