Musings on making scents with HydroxycitronellOL… this is one of those synthetics that you just have to do a lot of your own research to discover what it’s all about. I could barely find anything at all on the net about HydroxycitronellOL. The product description on the Hermitage Oils UK site made me curious enough to purchase a small amount because I would really like to create a rose accord that thrills me so I was on the hunt. But that’s not enough with the synthetics, it’s important to throw the net a lot wider when experimenting with these tools.
Common name(s): HydroxycitronellOL
Chemical name: 3,7-dimethyloctane-1,7-diol
CAS #: 107-74-4
Supplier: Hermitage Oils UK
Blends well with: bergamot mint, bois de rose, ethyl linalool, farnesol, ho wood, leerall, mughet ethanol, petitgrain, ylang ylang, linalool, etc.
Interesting bits: Very mild (weak) clean-sweet, floral odour of considerable tenacity. The floral type is Rose-Peony, typically less green, less Lily or Muguet than the aldehyde. This alcohol, now often manufactured as an intermediate in the production of Hydroxycitronellal, is used in perfume compositions originally with the intention of stabilizing Hydroxycitronellal and prolonging the odour life of that aldehyde in composition. However, there are other uses for this alcohol, not always obvious from a brief glimpse at the odour, which is, truly, not immediately impressive. It has an excellent fixative effect upon many types of delicate floral fragrance, and as a blender/modifier for other types. (Steffen Arctander)
Their nose: Odour type is floral with a low odour strength has a mild, clean, floral note and is very long lasting and closer to rose than muguet, with aspects of lily and peony. (Hermitage Oils)

My nose: HydroxycitronellOL opens barely noticeable, quiet, slightly floral with a faint berry quality to it. At 15min it’s still floral, there seems to be hardly any movement, soft. 30min on this is plummy, jammy and juicy and oh, there’s the rosiness! Sort of sweet, too. 45min brings on a definite soft, floral note like linen sheets, becoming more present now and a bit metallic in quality tucked away somewhere. 1hr now and it’s clean, floral and fresh. 2hrs later there’s a much softer, more yielding, feminine, and pliable side to HydroxycitronellOL that reminds me of a mother. 3hrs now and it seems to be fading ever so quickly, I can barely get a good sniff. But there’s definitely still some of the floral soft quality hanging around. 7hrs, it’s base notes time, and our subject is a clean, clear and wispy floral note; wonderfully comforting now, inviting and intimate. The 12hr mark sees this one finally fading, getting quite thin , but I still have a good grasp, a good sense of the quality. Finally at 24hrs HydroxycitronellOL is gone. I can’t discern a thing other than a faint metallic smell that is thin.
HydroxycitronellOL & Rose Absolute, from Marocco: in the beginning the rose note is clean, the rough edges are all smoothed out, whimsical, titillating, I find it makes the rose much more “readable”, you’re clear about what you’re smelling – like it’s giving the rose a sense and structure. After 1hr the rose is much more subtle and compelling, it feels more grounded, more refined. At 2hrs the combination seems to have made the rose a lot more transparent, simplified it a bit and therefore making it much more approachable. It’s still quite present on the strip. After 5hrs there’s a wonderful crumpled, worn effect that reminds me of our roses when they are dying on the branches, there is still life held in their soft folds, they still want to give you something. It’s now soft and warm and yes, HydroxycitronellOL I think helps rose be more generous toward the end, very satisfying and earthy. After 10hrs the rose is there still on the strip, integral and totally identifiable.
Above, my colour interpretation of HydroxycitronellOL and Rose absolute. I used Prussian Blue together with Carmine.
Have a great Wednesday!
