Gouache is essentially a mixture of gum arabic (a harmless glue that is sometimes used as the adhesive on envelopes which you can lick to seal), water, and pigment. The only source of toxicity should be the pigment (coloring agent). Just off the top of my head, the most common pigments which are potentially hazardous are probably the cadmiums and the cobalts. There may be a couple of others. Usually the tube will indicate if the color is hazardous. There are non-toxic substitutes for any toxic color, which are not only safer but cheaper, and they work just as well in the gouache medium.

Since gouache uses the same ingredients as watercolors, maybe someone in the watercolor forums could give you an exhaustive list of colors to avoid.

Also, Winsor & Newton has safety data sheets (http://www.winsornewton.com/pdfs/DEGALL.pdf) on every color which has even the slightest chance of being harmful. Even so-called hazardous colors are harmless as long as you don't eat them or neglect to wash them off if they get on your skin. I just play it safe and very seldom use them.
