Uses Of Melamine & Ammonium Bicarbonate

Searched Wikipedia on these two substances... Scary to know its uses and that it found its way into our food system.

Melamine
Uses
Melamine is combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic, and melamine foam, a polymeric cleaning product. The end products include countertops, dry erase boards, fabrics, glues, housewares and flame retardants. Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.

Ammonium bicarbonate
Uses
Ammonium bicarbonate is used in the food industry as a raising agent (e.g., for gingerbread, digestive biscuit or Chinese youtiao) before the introduction of baking soda. Ammonium bicarbonate is still used in many food products, in addition to baking soda.

It is commonly used as an inexpensive nitrogen fertilizer in China, but is now being phased out in favor of urea because of its relatively low quality and instability. This compound is used as a component in the production of fire-extinguishing compounds, pharmaceuticals, dyes, pigments and it is also a basic fertilizer being a source of ammonia. Ammonium bicarbonate is still widely used in the plastic and rubber industry, in the manufacture of ceramics, in chrome leather tanning and for the synthesis of catalysts.[citation needed]

Safety
Ammonium bicarbonate is an irritant to the skin, eyes and respiratory system. Ammonium bicarbonate from China used to make cookies was found to be contaminated with melamine, and imports banned in Malaysia in the 2008 Chinese milk scandal.
