I found a vegetarian site, that discussed ICBINB, and apparently it's 60% soybean oil, with "sweet buttermilk" salt and colour added.

Wa'il is right about the harmful fats ...

for the stick type, the fat breakdown for 1 Tbsp =

10 gm total fat
2 gm saturated
2.5 gm monounsaturates
2 gm polyunsaturates

Hmm .. seems there's 3.5 gm of undeclared fat. Guess that must be the TRANS fat, which is linked to clogged arteries and some cancers.

The liquid form of course has more oil in it, so higher polyunsaturates. (and much lower trans fat)

Real dairy butter is made from cream and salt (unless unsalted) .. and you can use it for cooking without it turning into something harmful (most oil-based margarines and spreads have a low-smoking point, meaning they burn and scorch quickly, turning into transfats in the process). Of course, folks do have preferences, and prefer the "lighter" taste of an oil-based product.

It's up to you ... no health advantage to the ICBINB, from a lowcarber's perspective.

my 2¢ worth
