The present invention relates to novel compounds and their use as fragrance materials.

The present invention refers to indanone derivatives of formula (I) ##STR00001## wherein R.sup.1 is selected from hydrogen, methyl and ethyl; R.sup.2 is selected from hydrogen, methyl and ethyl, and R is selected from hydrogen and methyl; or R.sup.2 and R.sup.3 form together with the carbon atoms to which they are attached C.sub.3-C.sub.5 cycloalkyl; and R.sup.4 is selected from C.sub.2-C.sub.5 alkyl, C.sub.2-C.sub.5 alkenyl, C.sub.1-C.sub.4 alkoxy, C.sub.3-C.sub.5 cycloalkyl, and C.sub.3-C.sub.6 cycloalkenyl. The invention further refers to perfume compositions and fragrance applications comprising them.

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.

Systems, methods, and computer-readable media for a color reproduction service arc provided.

A fragrance mixture and its applications, in particular perfume oils, cosmetic agents, application agents or washing and cleaning agents, containing a sensory effective amount of (i) (E)-2-methyl-but-2-endicarboxylic acid diethyl ester, (ii) (Z)-2-methyl-but-2-endicarboxylic acid diethyl ester or (iii) 2-methylenebutanedicarboxylic acid diethyl ester and mixtures thereof and analogous esters derived from these compounds and mixtures.

A perfume composition providing differentiated odour depending on the assessment conditions is provided. The perfume composition includes a) less than 20% by weight of perfumery ingredients having an equilibrium headspace concentration (HS) between 151 and 900 microgram/l at 25° C., b) at least 35% by weight of perfumery ingredients having a HS higher than 900 microgram/l at 25° C. and b) 25% by weight of perfumery ingredients having a HS lower than or equal to 150 microgram/l at 25° C. The perfume composition reduces consumer perfume habituation to said perfume product.

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.

The present invention relates to novel compounds and their use as fragrance materials.

The invention includes an improved wax melt in a foam safety media of melamine for subsequent melting in a conventional warmer or other candle melting device. The melts release their fragrance when heated conventionally but remain associated with the foam safety media during use to be substantially spill-proof. The melts are produced by piping heated liquid wax with fragrance and other desirable components into a container that dispenses discrete quantities onto a melamine foam safety media on a moving conveyor for cooling and hardening and subsequent packaging into discrete wax melts in a melamine foam safety media.

The invention relates to a cosmetic process for treating keratin fibers, preferably the hair, comprising at least the steps consisting in: a) applying to said keratin fibers a composition containing at least one substance chosen from fatty substances, non-silicone polymers and surfactants, b) applying a mechanical tension to said keratin fibers, and c) exposing said keratin fibers under mechanical tension to microwaves, at a pressure ranging from 50 000 to 250 000 Pa, in the presence of at least one solvent in vapor form on contact with the keratin fibers and without there being complete drying of the keratin fibers throughout the entire exposure to the microwaves, the solvent(s) in vapor form being entirely generated by evaporating at least one compound present, before emission of the microwaves, on contact with the keratin fibers, step a) taking place prior to step c).
