Alpha Lipoic Acid 5% solution help?

[Allaboutyou83]

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.

This is basic mathematics .Percentage calculation. But the question is 5% w/w or v/v or v/w.

The easist would be if it is w/ w weight by weight.

100 g would be 5g lipoic acid and  95 g propanediol.

If you want to do the others need specific gravity to convert to volume.

100 ml would be 5 ml lipoic acid and filled up to 100 ml with the solvent.

The last would be 5 g dissolved to 100 ml. Solution.

All 3 are different.

By the way give no receipes for pharmaceutical drugs.
