Taboo to buy orderless items as a healthy being!?

I don't have any issues with fragrance, but I do sometimes every once in a while get paranoid with cleanliness, and sometimes I'll add fragrance to things then start panicking if it's clean or not. It's not fun, but feels taboo to buy anything orderless when I thankfully don't have any medical issues with smell.

is it wrong? 

(My bad if English not Englishing, I don't why lol :P)
