I don't perceive this to be misleading. No matter what you buy, you have to
read the
label carefully, and must be able to understand what you read.
A good example is 'sugar free'. That means it is not made with sucrose, or
common
sugar. It can be made of fructose, which is still generically a sugar, but
is better tolerated
by hypoglycemics and diabetics--calory count is the same. Maltodextrin
should be
considered to have the same effect on the diabetic as glucose, but it is not
defined
to be 'sugar' (sucrose).
'Synthetics' in motor oils can be similarly confusing. If I take an
alphaolefin and oligamerize
it to a lubricating oil specification, it IS synthetic. The alphaolefin was
in all likelihood
'synthetic'. If I distilled petroleum, took out certain cuts, and then
hydrogenated that
to make a good lubricating oil base, would that also be 'synthetic'.
Arguably yes.
