What is main ingredient of WD-40?

WD-40:

Who knew? I had a neighbor who bought a new car. I got up very early one
Sunday morning and saw that someone had spray painted red all around the
sides of his car (for some unknown reason). I went over, woke him up, and
told him the bad news. He was very upset and was trying to figure out what
to do.... probably nothing until Monday morning, since nothing was open.
Another neighbor came out and told him to get his WD-40 and clean it off.
It removed the unwanted paint beautifully and did not harm his paint job on
the car. I'm impressed!

WD-40 who knew? 'Water Displacement #40'. The product began from a search
for a rust preventative solvent and degreaser to protect missile parts.
WD-40 was created in 1953 by three technicians at the San Diego Rocket
Chemical Company. Its name comes from the project that was to find a 'water
displacement' compound. They were successful with the fortieth formulation,
thus WD-40. The Convair Company bought it in bulk to protect their atlas
missile parts. Ken East (one of the original founders) says there is nothing
in WD-40 that would hurt you... When you read the 'shower door' part, try
it. It's the first thing that has ever cleaned that spotty shower door. If
yours is plastic, it works just as well as glass. It's a miracle! Then try
it on your stove top ... Viola! It's now shinier than it's ever been. You'll
be amazed.
