Synth fixatives for naturals

Hi perfumers! Do you use synthetic fixatives for your natural fragrances? What is the best? Is there odorless fixatives?

My natural oil-based (FCO) fragrances last for 2 days on clothes or paper, but on different types of skin 1-3 hours. So the tenacity problem is in skin absorption. What kind of fixative should i use for not break a scent but add longevity to it?

Thank you!

There is an extensive discussion about the use of fixatives in this earlier thread that you might want to look at.

The short answer to your direct question is that, yes I normally use synthetic fixatives to help extend the tenacity of natural fragrance ingredients. The main ones I use are musks, but also things like vertofix, cedramber, ambroxan, evernyl and many others. All these things will alter the scent however - they are part of the perfume.

But then it is no longer an all natural fragrance; which makes it an even bigger nonsense.

Thanks Chris!
So I understand that's the base what should be longstaying. And some base components affect some others (not all and in different manner). For example oakmoss affect bergamot tenacity. Am'I right?

Yes, and as Jellinek once wrote: even bergamot oil may act as a fixative for lemon oil (in a very, very simple eau de Cologne type fragrance).

There are a lot of natural materials that can act like a fixative (or better: are suitable to make a better perfume), like vetiver oil, patchouli oil, many resinoids and absolutes, so you don't NEED synthetics here, in general.

Sorry, I just realised I missed that nuance in the original question - of course if it is an all-natural fragrance (I only have one of those in my range currently) then you have to use natural fixatives or it won't be natural any more. I use things like resins and balsams to achieve that mainly, though as Jan says almost anything can work to a degree.

My Relaxed repose fragrance relies on cedarwood, opopanax and olibanum as the main fixatives and does not contain any synthetics at all - that's the whole point of a fully natural fragrance after all - for the rest of my range I'm using a mixture, with most of the fixative effect coming from synthetics such as those I mentioned earlier.

I'm not sure you meant that as it came over. The answer for a any natural fragrance just has to be no. Also that would have to include the denatured type of perfumers alcohol too. The denaturants are not natural either.

Just the normal resins, woods and plant based musks will fix and they don't have to be in huge enough concentrations to alter the smell. There are many threads on this forum. Here is the identical question to yours.

Essentially me had a Botanical Musk Fixative but it needed a list of what was in it in what proportions to be of any use in a formula.

Are you trying to make a totally natural fragrance or just asking?
