NO!

Jet A was and is pure Kerosene.

JP-4, long gone, had all kinds of nasties like toluene, naphtha, etc added.
AFAIK, it was never used in civilian aircraft.

JP-4 was sold to the civilian market as Jet B and is still
available in some markets.

And then there's JP-7, specially formulated for the SR-71... throw a match
in this stuff, and the match goes out. Very high flashpoint because of the
SR's operating conditions.
