Compositions comprising pro-fragrances of fragrance ketones may be suitable for perfuming laundry, washing and cleaning agents, since they respectively release the respective ketones during cleavage. Such pro-fragrances may include the formula (I):

##STR00001##

A compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 2-phenylpropyl represented by formula (I) ##STR00001##
is disclosed.

The present invention relates to tetrahydropyranyl lower akyl esters and specifically to tetrahydropyranyl acetates, a method for preparation thereof using ketene and use thereof as fragrances and aroma substances.

A fragrance composition comprising one or more musk or fragrance accords for use in reducing or inhibiting a subject's physiological reaction to stress. The composition can be incorporated into consumer products.

A personal aerosol composition including a solvent, a cyclodextrin perfume complex, and a propellant, where the cyclodextrin perfume complex includes 10% or more perfume raw materials, by weight of the perfume, having: a cyclodextrin complex stability constant of about 3.0 or less, a C log P of about 2.5 or less; and a weight average molecular weight of about 200 Daltons or less.

Described herein are properfume compounds. Also described herein is a method to release a compound being a ketone or aldehyde, a formate ester and/or an alcohol by exposing a properfume compound to an environment wherein it is oxidized. Also described herein is a perfuming composition and a perfume consumer product comprising at least one properfume compound.

The present disclosure concerns a perfuming ingredient of a compound of formula (I) ##STR00001##
in the form of any one of its stereoisomers or a mixture thereof, and wherein X represents a CHO group when R1 represents a C1-2 alkyl group or X represents a CH(R6)CHO group when R1 represents a hydrogen atom or a C1-2 alkyl group. Each of R2, R3, R4, R5 and R6 represents, independently from each other, a hydrogen atom or a C1-2 alkyl group; or R3 and R4 represent, when taken together, a ethanediyl group; and —C(R3)(R4)—CH(R5)—OH group is, relative to position 1, an ortho, a meta, a para substituent of the aromatic ring or a mixture thereof. Also disclosed is the compound of formula (I) as part of a perfuming composition or of a perfumed consumer product.
