Solubility of Calone, Cetalox, Veramoss and Ambroxide in EtOH

[polysom]

I've ordered Calone, Cetalox, Methyl atratate (Veramoss) and Ambroxide. Because all of this are powders, I need to make a solution first. I would like to use Ethanol as a solvent. But I don't find the solubilities in Ethanol. Some have the solubility in water on TGSC. Does somebody know the solubility in Ethanol? Or can tell me at least if I should prepare 10% or 50% stock solutions or whatever?

You can always simply add them into your concentrate, undiluted...
They will dissolve in with all the other items in the formula.
(As long as you are working by weight, and not drops).

They will all work in a 10% dilution, or as Paul indicates, you can simply add them to your concentrate if you are working in weight.
I guess the question is...for what purpose are you diluting them? Is it to properly evaluate the odour profile, to save some money and make it go further when doing formulation trials, etc. , or perhaps another reason?

in my experience, i found it difficult with cetalox in 10% ethanol, especially when the temperature is a bit low (clumps into crystals) ... i put it at 5% .....

I've been having the same issue with Cetalox. I have it at 7% and have found it dropping out of solution and accumulating in the threads of the bottle even as well as accumulating on the spray nozzle. While I am in Chicago and it does get cold I haven't had this issue before. Seems to be happing "all of a sudden."

Any suggestions to combat this are appreciated!

I mistakenly made a 15% dilution of Maltol. Everytime I come back to it, it has recrystallized in the bottom.
So, I put it in the microwave for 25 seconds, then swirly shake invert it until all is dissolved, use what I need, and put back on the shelf until next time, and do it again.

Paul I do the same thing with some accords of mine. But I should’ve been more specific, I’m talking about the finished fragrance. I have a fragrance that is at 7% Cetalox and it’s dropping out of solution. I’ve probably made and sold over 40 bottles of this fragrance but just recently I’m having issues with solubility.

Most of these crystals or powder raw material will dissolve at 10 % (even 50%) in EtOH. The only problematic powder would be Maltol which desolve best in Benzyl Benzoate

Thanks for your answer. I don't have a scale that can weigh such small amounts. For me it is more convenient to work with volume instead of weight.

Yes, my Cetalox also does not dissolve very well. I will try 5%. Thanks.

Even something like this is much better than volumetric measurements.

FYI, I now made Veramoss 10% in Ethanol, Calone 50% in TEC, Ambroxid 10% in Ethanol and Cetalox 10% in Ethanol. For Calone and Cetalox, I had to heat them all up a bit to get everything to dissolve. All is still dissolved now, one day after. Maybe thats helpful for somebody with the same question...

Evernyl/Veramoss - 10% DPG works, 10% IPM fails miserably
Cetalox - 5% in ethanol works, but with a twist. It requires serious stirring, so a magnetic one helps big time. Also, a bit of heating helps big time. When it gets cooler, crystallization might occur, then heat a little again and stir again. For me it took 3 times (over 2 weeks time) heating and stirring again and now it is fully disolved and no more crystallization.
Ambroxide - 10% ethanol works great no issues
Calone - 10% DPG no issues I didn't need to heat at all, just good stir and that's it.

I’ve diluted all of these in ethanol aside from Cetalox. I follow a perfumer who uses Cetalox instead of Ambroxan and it seems she uses that same method as me.

I used a hot plate to melt the crystals and crushed them a little along the way when needed. Eventually they all melted and dissolved in ethanol. I assume the powders pill up when you dump them, so use a metal rod to break them up. I diluted to 10%.

Sorry for intruding but you can always dilute it further.

Yes, I could do that, Thanks...

Does regularly heating the material not have any detrimental effect on it?

 

[Bill Roberts]

No, provided that the temperature is reasonable. If using a water bath, I recommend no more than lightly "steaming" (vapors coming off of it.)

If one has a hotplate with thermostatic control, 50 C will get the job done with time.

I have found that heating a bowl of rice in the microwave and then placing the jar or bottle or flask into the heated rice is quite effective. Also you don’t lose the label if that’s an issue for you…..Which you would do in water [emoji846]

I have a 10 % solution of Cetalox in DPG. It took quite some heating and stirring to get it to disolve. After a few days I found that the entire solution had gone solid. It was easy though too get it to liquid again by placing it in a bowl with rice that had been heated for a minute in the microwave. I guess, I can live with having to heat it prior to use. The corresponding density change doesn't bother me, as I work in weight anyway.

Cetalox remains fully dissolved at room temperature at 20% in DEP.
