A declaration is not necessary, IMO. If I remember correctly, every bottle of sunscreen clearly indicates is purpose is to prevent cancer. Given that sunscreen has no other likely purpose and it is recommended by the government for medical purposes, it couldn't logically be considered anything other than a medical liquid. The trick, IMO, is justifying what amount is medically necessary to carny on.
