- the present invention relates to a non-aqueous fragrance mixture, preferably a perfume oil, comprising or consisting of
- one or more odorant (s) from the group of odorant alcohols in particular from the group of odorant alcohols with green odor notes and / or the group of odorant alcohols with flowery odor notes.
- the odorant mixture according to the invention is a non-aqueous odorant mixture.
- non-aqueous fragrance mixture in the context of the present invention is understood to mean a fragrance mixture which is characterized in that it has a water content of less than approximately 1% by weight or is completely anhydrous.
- fragment mixture is always understood to mean a non-aqueous fragrance mixture, even if this is not explicitly stated.
- the first component (i) of the fragrance mixture according to the invention is 1,3-propanediol.
- 1,3-Propanediol consists of the basic structure of propane, at the terminal positions of which there is a flydroxy group.
- 1, 3-propanediol belongs to the group of dihydric alcohols, the diols. It is a colorless, hygroscopic liquid with only a weak or no odor of its own.
- 3-Propanediol can be produced either by chemical synthesis or by microorganisms biotechnologically from corn or from glycerol, which is obtained as a by-product of the transesterification of vegetable oils in the production of biodiesel from rapeseed oil. As a result, it is a sustainably produced product that is easily accessible.
- 1,3-propanediol has so far not found any noteworthy use, in particular not as a solvent in the preparation and production of odorant mixtures.
- 1,2-Propanediol is a clear, colorless, almost odorless and strongly hygroscopic liquid. 1,2-Propanediol is used because of its dissolving and emulsifying properties, among other things, as a carrier or as a carrier solvent for dyes, flavors, emulsifiers, etc. or is used in cosmetic products such as skin creams, toothpaste, mouthwashes and deodorants mainly as a solvent or humectant.
- 1,2-propanediol is produced synthetically by hydrolysis of propylene oxide.

- Dipropylene glycol (DPG) is obtained as a by-product in the production of 1,2-propanediol.
- Dipropylene glycol is a colorless, hygroscopic, viscous, odorless and not very volatile liquid.

- 1,3-propanediol has additional positive secondary properties. These secondary properties include: high stability under certain application conditions, for example in alkaline media, e.g. washing powder, fabric softeners, soaps, shampoos, etc. Furthermore, it has been shown that 1,3-propanediol is less reactive and therefore inert compared to 1,2-propanediol compared to odorous substances, whereby in combination with one or more odorous substance (s) the odor profile is not adversely changed, for example through the breakdown of odorous substances or through the formation of by-products. Furthermore, 1,3-propanediol shows an antibacterial effect.
