    Abstract: A 2-(alkyl-cyclohexyl)-1-propanol is disclosed. The compound is represented by formula (I): wherein R1 and R2 individually represent a group selected from the members consisting of methyl-, ethyl-, n-propyl-, i-propyl-, t-butyl-, and sec-butyl groups, provided that the total carbon atoms of the R1 and R2 groups are 4 to 7; either R1 and R2 is a hydrogen atom, the other being a cyclohexyl group; or R1 and R2 together form a hexamethylene ring together with 2 carbon atoms in the cyclohexane ring. The compound possesses a long-lasting, woody, floral odor, and can be widely used as perfumery materials such as perfumes, soaps, shampoos, aromatic goods, and detergents.

    Abstract: A reformed vetiverol comprising 40% by weight or more of khusimol and 10% by weight or less of isovalencenol is disclosed. The vetiverol, containing a small amount of isovalencenol and a large amount of khusimol imparts a milder and more elegant odor than conventional vetiver oils or vetiverols. The reformed vetiverol can be prepared by a process comprising: esterifying alcohol components in a vetiver oil or a vetiverol, heating the esterified vetiver oil or a vetiverol to thermally decompose isovalencenol esters, hydrolyzing the remaining esters into alcohols, and separating the formed alcohols.
