A perfume composition having controlled release of phytoncides in an atmosphere in order to generate an air condition resembling the air environment of a forest is provided. The perfume composition includes a) at least about 0.6% by weight of at least one phytoncide; and b) a perfume mixture including (i) at least one solvent; and (ii) at least one fragrance ingredient. At least about 25% by weight of the at least one phytoncide is selected from the group consisting of pinene alpha, pinene beta and combinations thereof.

This disclosure relates to a composition containing a fragrance and a porous cyclodextrin-based metal organic framework (CD-MOF). The CD-MOF includes at least a metal cation and a plurality of cyclodextrin molecules.

A compound is provided of Formula (I)

##STR00001##

wherein R.sup.1 represents a C.sub.3 to C.sub.20 hydrocarbon group derived from an alcohol of formula R.sup.1OH, from a formate of formula R.sup.1OCHO, or a cinnamyl aldehyde of Formula (II)

##STR00002##

wherein a compound of Formula I is capable of releasing a compound, when oxidized, selected from the group consisting of a fragrant alcohol of formula R.sup.1OH, a fragrant formate ester of formula R.sup.1OCHO and aryl aldehyde of Formula (III)

##STR00003##

wherein R.sup.2 is, independently, hydrogen atom, hydroxyl group, optionally substituted C.sub.1-C.sub.6 alkyl group, C.sub.1-C.sub.6 alkoxy group, or O(CO)CH(CH3).sub.2 wherein any two of R.sup.2 may form an optionally substituted 5 or 6 membered ring. The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols, fragrant aldehydes or fragrant formates.

The present invention provides a perfuming composition that is free of ethanol and that is in the form of a transparent, clear microemulsion that contains a fragrance at a concentration of 0.5 to 50% by weight; a solvent at a concentration of 1 to 36% by weight; a non-ionic surfactant at a concentration of 1 to 35% by weight; an ionic surfactant at a concentration of 0 to 12% by weight, a cooling hydrotrope at a concentration of 0.01 to 12% by weight and water. Said microemulsions benefit from the presence of a cooling hydrotrope which allows lowering the amount of surfactant needed and provides a cooling effect.

Disclosed is a fragrance adduct that is a reaction product between a polymeric amine and a reactive fragrance ingredient. The polymeric amine contains a backbone and at least one amino functional group, the reactive fragrance ingredient is an aldehyde, a ketone, an ,-unsaturated electrophilic compound reactive towards the polymeric amine, or a combination thereof, and the reaction product is an imine compound or a Michael addition adduct. The fragrance adduct can be formulated into a fragrance composition, household product, personal care product, hair care product, or beauty care product. Also disclosed is a method for sequestering a fragrance using the fragrance adduct.

A process for extraction of crude oil from distillers dried grain solubles and/or distillers dried grains and producing corn distillers meal that may be used as a livestock supplement is disclosed. For example, the corn distillers meal may be used as a crude protein supplement for use in a livestock feed diet or a poultry feed diet. The solvent extracted crude oil may be suitable for oleochemical processing for personal care and home care products, biodiesel production, and/or renewable diesel production from hydro-treating the extracted oil to make green diesel fuel.

A process of making fragrance compositions by adding solvents with different polarity before and after a filtering step to accelerate precipitation of e.g. waxy carry-overs from perfume oils.

This disclosure relates to a composition containing a fragrance and a porous cyclodextrin-based metal organic framework (CD-MOF). The CD-MOF includes at least a metal cation and a plurality of cyclodextrin molecules.

A fragrance composition is described which comprises at least two different fragrance accords, wherein at least 30 wt % of each fragrance accord comprises the key contributor(s) of said fragrance accord and wherein the average of the odour detection thresholds of said key contributor(s) for each fragrance accord is within the same order of magnitude as the average of the odour detection thresholds of the key contributor(s) for said other fragrance accord(s), and wherein the base note(s) of each fragrance accord comprises less than 15% of the notes of said accord. Methods of manufacture thereof, together with methods of attenuating fragrance habituation, are also described.
