The fragrance enhancing capacity of the compounds is described in methods for their use both as perfumes and perfume enhancers or boosters.
Claims14
A method of providing a fragrance to a composition, said method comprising:
- (a) providing a composition;
- and
- (b) adding a fragrance-providing effective amount of an aldehyde to the composition, wherein the aldehyde is prepared by hydroformylation of a cyclooctadiene, with the proviso that the aldehyde is not a cyclooctane aldehyde.
A method of enhancing fragrance characteristics of a composition, said method comprising:
- (a) providing a composition comprising one or more fragrant components;
- (b) providing an aldehyde prepared by hydroformylation of a cyclooctadiene, with the proviso that the aldehyde is not a cyclooctane aldehyde;
- and
- (c) combining the composition and a fragrance-enhancing effective amount of the aldehyde.
