Hmm. The man-page doesn't meantion this, but i tried it

stat <file>
touch <file>
stat <file>

and all 3 times were the same after touching it.

man touch
- snip -
       Update the access and modification times of each FILE to the current time.
- snip -

I would have guessed that changing atime/mtime doesn't change ctime.
