eliminating odors

What chemicals eliminate odors besides the basic peroxide or baking soda? Maybe somthing a little stronger?

Its often easier to mask than eliminate.

I have heard that tcep is used to eliminate odors. Is this true?

It depends on what is causing the odors. Many of the worst smelling compounds are thiols and small carboxylic acids. Small carboxylic acids get absorbed very nicely by weak bases like sodium bicarbonate, and the thiols are nicely oxidized by the hydrogen peroxide. There are also some amino compounds which are very smelly, and are absorbed best by vinegar or other acids. Some examples of common nasty smelling compounds are propanoic acid (partially responsible for smelly feet), caproic acid (smells like goats or other farmyard animals), putrescine and cadaverine (small diamines, responsible for the smell of decaying flesh, bad breath, and other bodily odors), methanethiol (rotten cabbage, bad breath, flatulence, and many other biological smells).

If you know what you are trying to remove from the air, the choice of chemicals becomes very simple.

Well, that depends at least slightly on what "tcep" is an abbreviation for.  You might also save time by actually telling us what odor you hope to eliminate, and their source.  As an example, if you've spilled perfume or solvent on a wooden floor, nothing but time and ventilation will help.  Baking soda an absorb thiol or other acidic odors, but only if there are traces in an tightly enclosed area with decent surface area of baking soda to react.  I'm talking refrigerator area, not room sized.

*EDIT*

You know, basically what fledarmus: said.

Im looking at trying to make a homemade scent eliminator to spray on my clothes to go hunting with. So i can not be detected by the animals. the active ingredient in febreeze is beta cycl. If I wanted to make this to sell I could not use that I dont think because they have it patented of course. thanks for the insight. Im also worried about the tcep because Ive heard it can be dangerous?

I don't know if the company in charge of febreeze has patented their formulation, or the ingredient.  But I don't think that precludes you from using it in a formulation of your own.  I don't know if anything will sufficiently mask all human scent molecules, given that they're constantly produced.  I know part of the human scent is butryic acid, and other large fatty acids, but I don't know if they can fit in the febreze "cage."  You've got parts of an idea, and parts of the problems you might face, but nothing complete enough for a good economic plan.

Im really just rying to mask the scent that would be in the clothes. Do you know any other chemicals that I could buy that might work? what about the tcep?

Is the tcep you are talking about
tris(2-carboxyethyl)phosphine

A reagent that breaks disulfide bounds into twin thiols doesn't remove odors, it creates them instead.

Well im at a stand still on what chemicals could work? This info is kinda hard to find. So ya think that the beta cyclo. is a good bet?
