Interesting!
It looks to me as if the propanediol was more dehydrating for the strawbs - hence their shrivelled-up-ness and the runnier liquid? So - if water is life, then it did suck the very life out of them : )
Will look forward to the sniff test results!
Thanks,
Sarah

Hello! I have your The Art of Making Glycerites Book and i was wondering if i can apply the glycerin extration methods you are giving to extract in propanediol, or it s just a different story ?

Hello Eleftheria Iliadi - As a starting point you can apply the same methods. HOWEVER: there will be differences in added water amount, infusion time and straining process with quite a few materials. Start with a few small side by side infusions to get a feel for the differences in the 2 materials - and have fun with it! :)

Hi Lise!I was wondering if you had an opinion on the correct required •minimum• percentage of either of the above solvents, when working with fresh materials, in order to make it 'self-preserving'?
For example, from my experience in herbal practice, I've learned that when preserving a fresh succus, one must use 20%, or 25% 190proof ethanol (depending on who you ask/read). I was about 2seconds from adding 40gms of ethanol to my 160gm fresh plantain leaf succus, when I suddenly remembered a blog post of yours regarding making glycerites with fresh material..I'd love for this to be something that could be used comfortably(topically), without the drying of the skin that alcohol can cause. Especially as this is to be part of a healing wound lotion.
Thank you for any response you choose to share with me. I hope you are well.
Muchlove, suki

Hi Suki-san - Great to hear from you!

Your questions are answered in my book The Art of Making Glycerites for Cosmetics in details. There are calculation charts for working with both self-preserving glycerites and glycerites with added preservative. Check the shop at LisaLise.com for more detailed info on what the book contains.
