Thank you for your comment. Alcohol extraction is an old technique to extract oil from herbs together with other chemicals. That is why alcohol is often used for tincture making. Difference is for oil extraction pure or very high concentration alcohol is used but tincture is normally medium level like vodka. As I talked in the video solvents like hexane is used for Rose concrete making. But hexane is toxic which is not home friendly and that is why it is replaced with high concentration alcohol.
Hello Dector
Thanks a lot for the precious information .
Could you please share a vedio of extract the rese absulte with hexane

If I want use it for perfumery can I keep it with the alcohol and not distill?
Please advise or share link for the follow up
What about the smell is it a stronger and longer lasting smell than essential oils?
Absolutes are stronger, smell more like the actual thing and last longer
Please explain the distillation process after extracting the rose in alcohol. Thank you.
Hi. Dr mentions a video that explains this. I have had a look but I can't find. Has anyone else found it?
I haven’t found the video so sad
Very informative. Thanks for sharing.❤❤
Hi Dr Kwok, will soaking longer than 48hours for let's say 1 month help get a better rose absolute?
It is not necessary to take longer than a week time for solvent extraction.
Sir please explain rose concrete to rose absolute conversion process
Thank you 😊 💓
Thank you sir
Can we use alcohol 70?
Thanks for the video, so after soaking the rose petals in alcohol, how to separate the rose abselute from alcohol?
Low temp distillation. If available vacuum distillation is better to remove the solvent. Most simple way is let it vaporize in air or a water bath.
thanks
Do you believe using Grappa as the alcohol would be acceptable?
could you just let the alcohol evaporate?
Ok where is separation video
This is just half a video. Please make a full video
Doctor , interesting video,, but : sorry ,, that is not the good process... Fred /France/ city of Grasse / chemistry of fragrances...
Your story is too much. I think it would have been better if we talked while working on the story. Because people's time is very valuable
@@dameprasa4614 who are you? Get out!! You’re not wanted here.
I thought rasputin youtube was your personal property???
What an awful tease and waste of time. A tincture we don't need instructions for.
