Teach Soap

If I use kombucha instead of water in my lotion would the preservative kill all of the beneficial and good bacteria? I'm thinking the only way to know for sure would be to get it tested in a lab.

Also, I plan on making SCOBY mask. SCOBY is the mushroom like thing that makes the tea into kombucha. Some people say using SCOBY on the face is like a chemical peel. The recipe has SCOBY, some kombucha, oil and eo and maybe cucumber extract. Again my concern is using a preservative. Kombucha can sit out for months and months, as long as there is tea for the SCOBY to drink. By adding eo, oil and extract i'm wondering if I would need a preservative? I plan on selling these. I'm thinking as long as they are put into the fridge and kept there I will be ok. I think shipping time of less than 2 weeks wouldn't harm it.

The preservative is meant to kill all bacteria. It doesn't discriminate. Kombucha is also extremely hard to preserve.
Kombucha ferments. The fermentation grows bacteria which might be beneficial.
However, as soon as you add it to anything else, it becomes germ food.
It would spoil within a couple of days, even in the refrigerator.
By the time you would see any growth/mold with your eyes, there are billions of mold/germs/bacteria colonies that have grown.

Thank you for your answer. After thinking about this I concluded that I don't need the beneficial bacteria found in kombucha for my face mask. Bacterial is good for the gut, yes, but this is for the skin. SCOBY's contain cellulose and lots of vitamins including B vitamins and antioxidants that will all nourish the skin.
My next question is because there is so much bacteria in SCOBY what % should I use of my preservative? The one I used is NeoDefend which suggest using .75-2%. Should I use the higher percentage of 2?

I do have a pH tester. Should I use it on every lotion I make or just when using NeoDefend? I also have optiphen I suppose I could use that.
