I have read that the dosage of boron in the form of borax is
about 1/8 teaspoon to 1/4 teaspoon. However according to my calculations:
1/8 teaspoon = 0.625 ml
0.625 ml of borax = 0.625 x ....

> 0.625 ml of borax = 0.625 x 1.73 (density of borax) = 1.08g of borax
Theory and practice can be confusing.
There are too many variables.
#1) You say 'Borax'.
However, what kind of Borax?
Are you positive, your product is 99.9% Borax?
Or, are you talking about the 20 Mule Team Borax?
#2) You say 'teaspoon'.
However, what kind of teaspoon?
Assuming you have a standard U.S. teaspoon,
Google says it is of 4.92892 ml, therefore 1/8 of is 0.616 ml.
However, your teaspoon can be smaller or larger.
#3) You say 'density'.
Assuming we work with pure Borax, indeed its density is 1.73 g/cm3. However, the 20 Mule Team Borax is less than perfect; it's density is less. It contains other things, too, besides Borax. According to Google, the label on the 20 Mule Team Borax says it contains Borax (Sodium Borate), Lactose, Sucrose, Sodium Tetraborate decaydrate (Sodium Borate). Therefore its density is probably less than the above-mentioned number of 1.73 g/cm3.
#4) if the only Boron-related product we can get is the 20 Mule Team Borax, then how do we know what percentage of it is Borax?
> 1.08g of borax = 1.08 X 0.11 (percentage of boron in borax) = 0.12g of boron
> And 0.12g of boron is 120mg of boron. And I have read that the daily intake should not exceed 18mg.
> Unless my calculations are wrong, 1/8 teaspoon is still way higher than the recommended dosage.
> Any thoughts?
Ideally we would:
1) Get Borax of 99.9% purity, as opposed to the 20 Mule Team Borax;
2) Use our own designated teaspoon, as opposed to the standard U.S. teaspoon;
3) Have access to a small scale that can weight the Borax, in milligrams;
4) Then, and only then, can we use the '0.11x' multiplier. And
5) Then, and only then, can we tell, if 1/8 tsp of Borax is too large, or too small, for us.
I hope this will help!
