Here are the ingredients, from walmart's site:

And the 97% Fat-Free version:

Wafers: Bleached Wheat Flour, Isomalt, Sorbitol, Caramel Color, Palm Oil, Cocoa, Corn Flour, Food Starch-Modified, Salt, Baking Soda, Soy Lecithin, Natural Flavor, Sucralose. *Adds A Dietarily Insignificant Amount of Fat.

Edit: Apparently Wal-Mart has commented on this.. from this article:

"Ice cream melts based on the ingredients including cream," said a Walmart representative. "Ice cream with more cream will generally melt at a slower rate, which is the case with our Great Value ice cream sandwiches."


It is largely the guar gum and calcium sulfate that are holding it together. Neither of which are anything to be concerned about. Guar gum (a sugar extracted from beans), thickens in water much better than corn starch, is an emulsifier, and has properties that stabilize freeze/thaw cycles. It's often added to similar foods for this reason. Calcium sulfate, a common source of calcium, is great at trapping moisture, and when used in conjunction with guar gum, greatly enhances the gum's ability to thicken and stabilize. This is actually really good chemistry at work here, and nothing to be grossed out about. The chemiphobic bull is definitely uncalled for here.
