Abstract: The present invention relates to a new high-throughput process for reducing impurities in essential oils and extracts (in particular for fragrances, fragrance ingredients, flavours and cosmetic ingredients) under mild conditions. Undesirable natural components such as waxes, but also synthetic materials such as agrochemicals and other environmental pollutants are reduced by using at least one selective nanofiltration membrane. In addition, the present invention relates to a method for reducing coloured components in essential oils to obtain a less coloured or even colourless essential oil, while achieving high re-colouration stability over time. Further, the odour quality is maintained or increased through reduction of undesirable olfactory substances to achieve a purified and higher quality oil.

Abstract: The invention relates to mixtures having: components (a) having at least one fragrance of the formula (I) where R1=OC—R2, CH2OR3, C1-C8 open-chain or branched aliphatic radical, optionally substituted and/or unsaturated, with R2=an open-chain or branched aliphatic radical, optionally substituted and/or unsaturated, having 2-10 C atoms, with R3=an open-chain or branched aliphatic radical, optionally substituted and/or unsaturated, having 1-8 C atoms, and components (b) having at least one fragrance, different from the fragrances of component a, characterized in that the weight ratio of all components (a) to all components (b) is from 1:10 to 1:10000.

Abstract: Suggested is a perfume composition, comprising (a) Petit grain oil and (b) Hydroxy carboxylic acid esters, which is particular useful for fighting various malodors.

Abstract: The present invention primarily relates to fragrance substance mixtures, preferably perfume oils, comprising (a) compound (A-1) and compound (A-2) and (b) one or more further musk fragrance substances, which are not isolongifolenyl methyl ethers, wherein the mass ratio of the total quantity of musk fragrance substances of constituent (b) to the total quantity of compounds (A-1) and (A-2) (constituent (a)) is preferably greater than or equal to 1:2. Furthermore, the present invention relates to perfumed products containing fragrance substance mixtures of this type according to the invention, in particular perfume oils, and a method for modifying certain olfactory properties of fragrance substances, fragrance substance mixtures, perfume oils or correspondingly perfumed products.

Abstract: A description is provided of the use of certain carboxylic acid esters as a fragrance substance, preferably as a fragrance substance for conveying, modifying and/or intensifying one, two or all the fragrance notes fruity and green, preferably both the fragrance notes fruity and green.
