Okay.
Beantree is the
trade name for the chemical Capryl Isosterate. The only information I was able to find on Capryl Isosterate seems to be the
original patent application - which indicates that it's made from two other chemicals, capryl alcohol and isostearic acid.
Capryl Alcohol is another name for Octanol/Octyl Alcohol, which is an
restricted alcohol.
Isostearic Acid is a clear, oily liquid that is used in a wide variety of cosmetics and personal care products.
So. It's
not natural, and it doesn't seem to be available for hobbyist/crafter purchase yet. It looks like a company called
Alzo is the main manufacturer - and there are some US distributors, but I'm thinking you have to be a pretty big company to get your hands on it.
That was a fun search.
