Does deodorant spray going through throat break fast?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

In principle, if any substance that has a body is passed down one’s throat then it will break one’s fast. However, if such a substance goes down unintentionally, then it will not break the fast. [1]

Aerosol sprays have a defined body due to the vapours contained therein. If one is not cautious while applying these sprays and it goes down the throat, it will break one’s fast. However, if someone else is spraying and the vapours go down your throat, while you did not intend to inhale it, then your fast will not break.

One should exercise caution in using any substance that may jeopardize one’s fast.

And Allah Ta’ala Knows Best
