@stockpilingallthecheese halal deodorant should be free from harmful ingredients.
I hope it’s not a stick deodorant which instructs the user to “Push up bottom before use” because there’s nothing halal about that sort of thing. 
Joking apart, although the products of some of these MLMs are classified as halal I’m amazed MLMs are allowed to operate in the Middle East as they’re harmful due to the high levels of debt people run up. Getting into debt in countries where sharia law is in force is a criminal offence which can land people in prison.
