Edible Chelators and Preservatives

Posted by cosmetic_chemist on May 14, 2022 at 11:14 pm

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!

Thank you

Preservatives: Benzoate, sorbate, and glycerin (propylene glycol may be possible) or sugar alcohols. The other glycols are not edible as far as I know (they’re at least not properly tested). Glyceryl monoesters are used as food processing aids, though I’m not sure if glyceryl caprylate is amongst them…

Chelates: Citrate and phytate.

Your best bet would be to stick to food grade Sodium Benzoate, Potassium Sorbate, Citric Acid, L-Ascorbic Acid
