    for what it’s worth, the major manufacturer of arginine is Ajinomoto (who also make 30% of the world’s supply of monosodium glutamate, and numerous other amino acid-related chemicals); if you can find a local distributor for their products, that’d be the most reliable source
    @Pharma arginine isn’t that strong a base compared to guanidine or hydroxide

    @Bill_Toge True on a mathematical scale though I’d suppose it’d feel nearly as bad bathing in it than it would feel bathing in an equimolar potassium hydroxide solution. What I meant with ‘invented by mother nature’ is ‘produced by living organisms’ and arginine is the one I know which probably holds the lead. BTW it falls just half a pK unit short of guanidine. I wouldn’t phrase this ‘that strong a base’ but rather ‘a slightly weaker base’ ;) .
    Brushing my teeth with it… I’m now seriously doubting if that’s such a good idea without something else in the toothpaste to ‘take off the edge’… Maybe/probably/likely it’s really arginine bicarbonate which is actually added??? Gosh… @devo2 contact a manufacturer such as Colgate and ask them (and/or get the SDS or other specs)! I’ve never measured the pH of a commercial toothpaste but I kinda can’t imagine it being in the 13th.

    hi @Bill_Toge any idea on what is the limit for “courseness” to not cause pain ?

    @devo2 the abrasive silica we used in most toothpastes had a particle size of 10 - 30 µm; not sure how this compares with calcium carbonate, but generally speaking, the finer the better
