Hi everyone,
First of all excuse me if this is not the right forum to post this.
I am sure this will be an easy question for someone with a basic level of chemistry (who is definitely not me).
My mum used to use a facial serum that had 5% of Thiotic Acid (Alpha Lipoic Acid) diluted in Propanediol.
It was a 30ml solution.
The brand (The Ordinary) stopped selling it and she loved it and I wanna try to make it for her.
Can anyone please tell me how many miligrams or grams of Alpha Lipoic Acid I would need to get a 30ml 5% ALA solution (propanediol as base).
Would I need to heat it to disolve it or no heat is needed?
Thank you very much to anyone that can help.
Dan
