Continental makes the foldable Grand Prix 4-Seasons in 700x25c and 700x28c and the GP 4000 in 700x25c. Some other manufacturers also list some models with foldable beads in 25c such as Michelin Pro Race, but they can be tough to find.
In addition to thse mentioned below,
I found on Page 43,
Conti Contact Extra Light Reflex 700x42c, Foldable
Conti Travel Contact 700x37c, Foldable
and on page 49
Conti Twister Pro 700x32c, Foldable
These should give some touring options.
