Which foods, medications, cosmetics, and toiletries are Chametz?
From Halachipedia
Chametz before Pesach
- Strictly speaking a toothpaste doesn’t need to be kosher lepesach, however, if it’s available one should have a kosher lepesach toothpaste. [1]
Chametz sent in mail before Pesach
- If one sent Chametz in the mail to a friend before Pesach and it’ll still be in the mail at the beginning of Purim, the sender should do Bitul Chametz for that Chametz as well. [2]
