Procedure

The addition of 100 parts by weight of (6RS,7RS)-5,5,6,7,8,8-hexamethyl-3,4,5,6,7,8-hexahydronaphthalen-1(2H)-one to the above-described eau de toilette imparted to the latter a powerful musky and earthy connotation, having also a well appreciated aspect which is slightly ambrette and pine. The overall effect was in-between the one which could have been brought by the addition of CASHMERAN® or TONALIDE®, however the substantivity was by far superior to that which could have been imparted by the addition of CASHMERAN®, and its musky-ambrette character was more elegant than the one provided by TONALIDE®. The addition of (6RS,7RS)-3,5,5,6,7,8,8-heptamethyl-3,4,5,6,7,8-hexahydronaphthalen-1(2H)-one or (6RS,7RS)-5,5,6,7,8,8-hexamethyl-3,4,5,6,7,8-hexahydronaphthalen-2(1H)-one, instead of (6RS,7RS)-5,5,6,7,8,8-hexamethyl-3,4,5,6,7,8-hexahydronaphthalen-1(2H)-one, to the above-described eau de toilette provided a more classic fragrance, wherein the earthy-woody effect was more pronounced than the one which could have been obtained by the addition of TONALIDE®.
