  • Trying to make an organic toothpaste

    Posted by Treeski on July 1, 2018 at 9:58 pm


    I am a newbie to this forum. I am trying to make an organic toothpaste. I am having an issue with separation of the formulation.
    My ingredients are as follows:

    Coconut oil, Peppermint oil, calcium powder, Xylitol, diatomaceous earth and Agar, distilled H2O

    My issue is that the mixture has come out “globby” and the oils will not incorporate well. I’m getting a lot of separation between the oil and the base mix.

    Does anyone have ideas on how I might salvage this mixture?
    Thanks in advance for your help.

    No emulsifier. I suggest you spend some time studying the nature of polar and nonpolar substances, and emulsification, before embarking on the project.
    And what do you mean by “calcium powder”? Calcium is a violently unstable element which oxidises to quicklime which can dissolve corpses. Even calcium hydroxide would result in a very high pH.

    Probably only Glyceryl cocoate/oleate/stearate can be considered natural emulsifiers.

    To make it truly organic/natural you’d probably need an anhydrous (no water) formulation, so everything is suspended, not dissolved in coconut oil. IDK how that’ll feel though.
    Coco oil melts in hot weather so you’d need some naturally found gums and thicker “oils” like beeswax to thicken it while keeping it truly natural.

    You’d need Calcium carbonate or so. Not metallic Calcium, God forbid.

    You’d need a surfactant (detergent) to at least provide some foaming.

    There’s some unfulfilled market for truly natural toothpastes. But you’ll need to read and experiment a lot lot.

    Thanks so much. Do you have any experience in making toothpastes? If so, maybe we can chat offline?

    I used Calcium Carbonate. Thank you so much for your input. I greatly appreciate it!

    You will need abrasives combined with calcium carbonate, organic alternatives for solvents

    @omegle: To help with the separation issue, try melting the coconut oil first before mixing in the other ingredients. An emulsifier like lecithin could also help bind the oil and water components. Adjust the ratios to find the right balance. Let me know if you have any other questions.
