Best way to preserve herbal water extract?
Hello all,
I would like to make a large batch of an herbal extract by simply boiling and straining herbs, and then bottling it up in a large container to use over time in my formulas. Would things such as potassium sorbate or sodium benzoate be sufficient for this? I am ok using something like phenoxyethanol if needed but would like to stay away from parabens and formaldehyde donors.
This extract will then be going into formulas that use optiphen plus or euxyl 9010 as the preservative. Any input is greatly appreciated, thank you. -

In addition to manipulation in production, extract will be repeatedly dispensed in production of multiple product batches until exhausted.
Suggest preservation as if finished product. Suggest sodium benzoate with pH adjusted appropriately and phenoxyethanol. Are you willing to use EDTA? -
thank you for your suggestion, so would you say 50/50 benzoate/phenoxy at a combined percentage of maybe 1%?
I have been using sodium phytate as my chelating agent and would prefer to continue with that instead of edta.

Like phyate. Suggest 2500 Na Benzoate and 5000 phenoxy. and
would adjust pH to 4-5.
