Use of isomeric farnesene product-by-process for augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles

A process for augmenting or enhancing the wet petal, white flower aroma of a consumable material selected from the group consisting of (a) perfume compositions, (b) colognes and (c) perfumed polymers comprising the step of intimately admixing with a perfume composition base, a cologne base or a polymer, an aroma augmenting or enhancing quantity of a farnesene isomer mixture produced according to the process of dehydrating a nerolidol isomer mixture containing nerolidol isomers defined according to the structures:

• ##STR54## in the presence of a catalyst selected from the group consisting of potassium acid sulfate and paratoluene sulfonic acid at a temperature in the range of from 110.degree. C. up to 200.degree. C. and at a pressure in the range of from 1 mm/Hg pressure up to 200 atmospheres pressure, absolute during the reaction, simultaneously removing water of reaction from the reaction mass, and then distilling the resulting product at a temperature in the range of from 51.degree. up to 103.degree. C. and a pressure in the range of from 0.7 up to 2.0 mm/Hg, with the proviso that when a potassium acid sulfate catalyst is used, the temperature of reaction is in the range of 180.degree.-200.degree. C.;
• and with the further proviso that when using a paratoluene sulfonic acid catalyst, the reaction temperature is in the range of from 115.degree. C. up to 200.degree. C.
