The exact quantities of each of the ingredients
is likely kept by the manufacturers as secret, but
the list of ingredients still gives some clues.
FDA regulations require that the
ingredients be listed in descending order of
predominance, meaning the product contains
more of the ingredients at the beginning of the
list. There are a few exceptions to this, such as
active ingredients being listed first (and
declared as such), and ingredients comprising less
than 1% of the total product being listed in any
order (after the other ingredients).
