1. Can I say "chemically composed of"?
2. Which one should I use: likely to go off/is not liable to spoiling/spoilable?
Since it is chemically composed of wax esters, it is not likely to go off/is not liable to spoiling/spoilable.
Thank you in advance!
chemically composed is fine, though checmically seems redundant to me. For the second part, you can use "... is not likely to spoil/deteriorate".

I'm not familar with "go off" in this context though I've heard "go bad" .
Anyway, "go bad" is informal and you need something of higher register there.
