You have to breath

, you can minimize your scent some.
I don't know if it is a fact, but I've read people are a bacteria farm, the byproducts of bacterial metabolism are what the Deer smell.
Something else to keep in mind is, many animals see farther into the light spectrum than we do. Brighter and whiter laundry detergent is a no,no. Quote "Unlike humans, deer don’t have an ultraviolet (UV) filter in their lens, making their eyes far more susceptible to the sun’s damaging UV rays. The trade-off is that researchers surmise deer can see UV light — something humans can’t detect." They also see blue well, which is what reflects off of fabric brighteners and some dyes.
I blew many low light hunts before I figured out it was likely I glowed to a Deer or Hogs, especially Hogs or Fox in the moonlight. Camo does you little, to no good at all, if it reflects a lot of UV light. Some of the dyes used in clothing are UV reflectors.
I have a UV light, I was shocked when I shone it on my hunting clothes. One reason I'm now fond of surplus military clothing, they use non UV reflecting dyes. Anybodies guess if that dandy Camo made in China uses UV reflecting dyes or not?
Motion and sound discipline are also important. Most wild animals pick up motion really well. Any unnatural sound is likely to alert them at a minimum and may trigger a flight response.
I use half handful of scent free bar soap, grated on a cheese grater and half handful of Borax in the washing machine. If you want to try a cover scent, put a tablespoon of Vanilla extract in the softener tray.
Point is, it is the total package and no just scent. I try to minimize what I can.
