Edible Chelators and Preservatives
I am currently working on some edible adult novelty products and am looking for chelators and preservatives that are safe to ingest.
For preservatives, I was thinking of Potassium Sorbate paired with sodium benzoate. Or Caprylyl Glycol, Propanediol, Glyceryl Caprylate (Not sure if this is edible)
I am going to add vitamin E as an antioxidant as well.
Would you recommend any other preservatives? They should be compatible with emulsion systems, solubility in oil or water, either pH independent or functional between 4-7
Are there any blends in the market that you think would work well?
I really appreciate your help!
