Question: Labelling of extracts/lysates/juices, adenine...

PharmaPharma Member, Pharmacist
Good evening community,
Could someone please shed some light on some questions of mine? That'll be great!
- If a juice such as aloe vera leaf juice or a dry plant extract is used, it counts as one ingredient. If a liquid extract is used, it's dry weight counts as one ingredient whereas the solvent (e.g. water, ethanol) is added to the amount of water (or ethanol etc.) present in the whole product. Right? What if for example bifida ferment lysate is used? This is a mixture of mostly water, semi-digested culture broth, mashed bacteria, and bacteria poo, so to speak. Does that count as one ingredient? This would leave a huge "freedom of manipulation"... just add some more water to the culture right before processing it...
- A propos bifida ferment lysate and lactobacillus ferment: Is it just my impression or does every eye serum contain such ferments (even as seemingly major ingredient)? How much (by preference on a dry weight basis) do they really contain (say products such as Lauder ANR) and do these ferments actually do anything (except adding water and probably some lactate)?
- Regarding active ingredients: What about adenine? I also feel like this one is present in quite a few products. Does it work in cosmetics and what exactly does it do (I know what it does in vivo and in vitro)? Obviously, I'm referring to concentrations well above pixie dust. I happen to have some at home and am wondering if it's worth the trouble to include it in a cream for my wife. Notably, I'm formulating for fun, friends, and family, costs and time are of no concern to me.
