I looked at the MSDS fabric softener sheet and besides fragrance, it has Octadecanoic Acid aka Double Pressed
Stearic Acid. It also lists biodegradable cationic softeners. Another site lists the ingredients as Dipalmethyl Hydroxyethylammoinum Methosulfate, Softening and Antistatic agent, Fatty Acid.
And this is from a PDF at the manufacturer's web site: Dipalmethyl Hydroxyethylammonium Metholsulfate, Fatty Acid, polyester substrate sheet, Clay, Fragrance.
Here is a web site that lists a LOT of anti-static ingredients.
