Perfumes

Question

Do perfumes, hair spray, and deoderants need to be kosher for Passover? On the one hand, they are not normally eaten, but perhaps they are considered rauy le-akhilah? (I believe perfume has alcohol, and presumably could be consumed if someone was thirsty enough) Also, is the standard for what determines hametz, what is suitable for a human to eat, or what is suitable for a dog to eat? Thank you
