Hi my name is tsemhoi. I would like to know how to Formulate toothpaste at home like commercial type (I mean the texture) with easy but effective ingredients.

    Can't be done without at least (somewhat) specialized equipment, and the ingredients used are extremely hard to get for an individual user. How much money are you willing to spend to do this?

  • Thanks Bobzchemist! The reason I want to DIY is save money. But now u asking me this question "how much I am willing to spend" then I should cont. spending $5 a 100g tube of Commercial toothpaste.
    May I ask: which preservative is best for Toothpaste and Mouth Rinse if my home made contained Clove Bud and Peppermint infused water, Bi-Carb Soda, Calcium Carbonate, Coconut Oil, and sea salt. Thankyou for your kind share!

    in my experience, sodium methyl paraben is a good preservative for toothpaste; it's one of the few preservatives that dissolves readily in water, is generally recognised as safe, doesn't have a noticeable taste, and works in alkaline formulas

    (given that it contains bicarbonate of soda, your formula is likely have a pH of about 8 or 9)

    however, unless you've got an airtight mixer and a vacuum pump, you will struggle to get a smooth air-free paste

  • I would b over the moon if I can formulate like Commercial. Thankyou Bill_Toge. I will search online for that preservative. So hard to find the exact raw ingredients for Cosmetic and Skincare in Australia and I have no ideas which ingredients is best substitute. Especially those Ester (emollient) and Sillicon Crosspolymer OMG! Hihihi.
  • Hi Bill_Toge, The supplier here dont have that preservative avail... Can I preserve with Sodium Benzoate? But this is not Broad-Spectrum right?
  • Bill_TogeBill_Toge Member, Professional Chemist

    sodium methyl paraben is one of the most widely used preservatives in the world; hunt around for other suppliers, as someone somewhere near you is bound to stock it

    if you can't find it anywhere, try methyl paraben instead (you'll have to dissolve it hot water first)

    wouldn't recommend using sodium benzoate for toothpaste; if your pH is above 5 it won't work it all, and a toothpaste that acidic will damage the teeth

    $5 for a 100 gram tube?!?

    Wow...I need to move to Australia and start making toothpaste - I'd be rolling in money in no time.

    OK, so most toothpaste in the US uses a combination of a special grade of silica and xanthan gum to thicken the paste. Add some surfactants and flavoring and you're done.

    For home use, I would strongly suggest leaving the silica out - get the wrong grade and you could scrub the enamel right off your teeth. That would be very bad. Calcium carbonate works much more gently.

    Try the formulation here:

    I am reasonably sure that all the ingredients will be available to you.

    Also, experiment with varying levels of salt, which will help cleaning and preservation. The Neem in the formulas is actually optional. Make small batches.

    Fill this in squeeze bottles like you'd use for ketchup or mustard and keep them refrigerated when not in use.

  • Cool, Thankyou
  • Hi Bill_Toge and Bobzchemist, Im sorry to bother U two. I Desperately can not find an Preservative for toothpaste as suggested by two of you. But I have found 1 supplier here sell Phenonip
    INCI Name:phenoxyethanol (CAS # 122-99-6), methylparaben (CAS # 99-76-3), butylparaben (CAS # 94-26-8), ethylparaben (CAS # 120-47-8), propylparaben (CAS # 94-13-3).
    Is this the same and safe to use to preserve Toothpaste or Mouth-rinse?
  • Hi tsemhoi
    which suppliers are you going to? There are quite a few australian supplier sites that have different preservative systems and you can buy small amounts..

    If you use enough salt, you won't need a preservative...

    from my experiments with oral care preservatives in a previous job, I'd strongly suggest you avoid using phenoxyethanol and benzyl alcohol, as they both have an unpleasantly oily taste and a temporary local anaesthetic effect (i.e. they make the mouth numb for 5-10 minutes after contact)
