What kind of toothpaste is this?

I think someone used my toothbrush..well um I KNOW SOMEONE used my toothbrush! Last night I grabbed my toothbrush out of the holder , grabbed the toothpaste and started brushing my teeth. The next thing I know my mouth was burning and smelling like ICY HOT and low and behold there lay the icy hot on the other end of the counter. Someone used my toothbrush with ICY HOT! And let me tell you it does NOT taste good with toothpaste! I was spitting and sputtering and rinsing out my mouth. I thought at least my toothbrush would be safe! HA!
