The smell of chain stores is more closely controlled and studied than you would first guess.

It is mostly scents added to floor cleaning detergents.

Persil, the top laundry detergent outside the USA, is a good cleaner,
but it has a “pine forest” smell that I cannot accept,
even though I like to hike through real pine tree forests.

The scent of Tide laundry detergent is acceptable to me,
even though it seems clear that it is overpriced.

There is still debate about whether females can smell the so-called “MHC Genes” of males, and like/dislike a man based on that.

It is still weird to me that it has been proven that
Humans have thousands of genes that would allow us to smell as good as dogs,
but a large majority of these genes are “turned off”
by adding methyl groups to them.

Remember the movie line.....
“ I love the smell of Napalm in the Morning, It smells like victory.”
