2,2,3-trimethylcyclopentenyl acetone derivatives, organoleptic uses

Described are isomeric mixtures of farnesene prepared by dehydrating nerolidol using potassium bisulfate or paratoluene sulfonic acid and then distilling the resultant product at particular temperature ranges and particular pressure ranges in order to prepare a composition of matter useful for augmenting or enhancing the fresh green, herbaceous aroma and taste nuances of foodstuffs, chewing gums, medicinal products and toothpastes.

Use of isomeric farnesene product-by-process for augmenting or enhancing

Described are isomeric mixtures of farnesene prepared by dehydrating nerolidol using potassium bisulfate or paratoluene sulfonic acid and then distilling the resultant product at particular temperature ranges and particular pressure ranges in order to prepare a composition of matter useful for augmenting or enhancing waxy, white-flowery (magnolia-like, tuberose, gardenia-like) aromas with citrusy (lemon/lime), pettitgrain-like undertones and green top notes in perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, dryer-added fabric softener articles, cosmetic powders and the like).

Use of isomeric mixtures of farnesene for augmenting or enhancing the

Processes and compositions are described for the use in perfume aroma augmenting, modifying, altering and enhancing compositions and as perfume and perfumed article aroma imparting materials of mixtures of (i) 2,2,6-trimethyl-1-cyclohexen-1-ylacetaldehyde.
