I put oust in my armpits?

I was at my friends house and my armpits smelled really bad and i didn't have deodorant so i sprayed oust in my armpits. Shortly after word i was getting really hot but didn't take notice of it at first. but then once i got home i loked at my armpits and the hair was all globbed together and sticky. i Washed it out but it took a long time. Is it unhealthy to put oust in your armpits?
