While historically the use of strong scents/perfumes
Was used to cover up appalling B.O., this was mainly from other eras when personal hygiene meant bathing was something that occurred infrequently or not at all.
Europeans bathe as much as anyone else in the world, and that hold canard about French or others roaming around with a pong is getting old.
Being as this may what many do not subscribe to is the idea of dousing themselves with chemicals meant to prevent perspiration. Sweat is a perfectly normal biological function meant to rid the body of wastes in addition to cooling. You wouldn't want to stop the process of voiding liquid or solid waste would you?
Got on a NYC bus several days ago. At the back was sitting a group of several African young men. Could tell they were from that continent by the patios being spoken amongst themselves. They were all clean, well dressed and so forth; but the entire bus had a pong you wouldn't believe. Rather put on in mind of what the Black Stars locker room must smell like....
This was one of the newer NYC buses that are quite large vehicles, really two buses joined together, and had only a small number of passengers. Worse it being summer all windows were closed and the AC was running. So that pong was recycled inside that closed container of a bus...
Living in a place with a vast and growing homeless population am well acquainted with the scent of those who have not bathed in weeks (or years....) versus that of simple "sweat".
Upshot of all this palaver is that powerfully scented laundry or other products have nothing to do with covering up body odor, but simply are a result of makers following what marketing research tells them consumers want.
First time went to France on one's own and went shopping at Ed's was quite bowled over in the laundry product section. Shelf after shelf full of detergents and whatever that packed a powerful smell. This was some time ago now and things really have only gotten worse IMHO.
Many Americans who have moved and or otherwise living in France have noticed same:

On this side of the pond the largest and fastest growing consumer demographic is Latino-Hispanic market. That group seems to prefer *very* strongly scented laundry and other cleaning products.
