Formulating

To EDTA or not to EDTA

Posted by myraqureshi on April 27, 2019 at 1:18 pm

I have seen many modern Ayurvedic water based formulations which are not using EDTA. Is it VERY important to add this in? What happens if its left out?

A client developed an Ayurvedic formulation- See below. Has asked us to manufacture it. However there is no EDTA.

Can anyone help in letting me know whether this would be an issue in the long run so that I could advise. What would happen if EDTA isn’t added? We made a sample six months ago and there is no pH drift with this.
