Questions about acetone and nail polish?

I'm hoping someone around here may actually know something about this other than just assumptions. I'm certainly not a chemistry type of person, so I'm nearly clueless. My questions are regarding the use of acetone nail polish remover in nail polish. I know that it is a terrible idea to add acetone into a bottle of nail polish to thin it. What happens, chemically, when acetone is added to nail polish? I assume that because it's meant to break the polish down to remove it, that it must be doing something similar when added to the bottle. If you're curious about ingredients in nail polish, here are some:

Ethyl Acetate, Butyl Acetate, Nitrocellulose, Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer, Isopropyl Alcohol, and others depending on the brand

{http://www.prettyindulgent.com/pages/nail-polish-i... That's a link that includes more ingredients if interested.

It's recommended that nail polish thinner is used, not acetone. Ingredients in thinner are Butyl Acetate and Ethyl Acetate. I'm assuming then, that those two ingredients can evaporate in the nail polish causing it to get thick, hence why you readd them to thin the polish again.

So if someone could tell me what exactly happens when acetone is added to nail polish, or what ingredients specifically the acetone affects and what it does, that would be amazing!

    The solvents in nail polish and nail polish remover (that's the ethyl acetate, butyl acetate, isopropanol and acetone) are the materials that do the work of thinning the polish and dissolving the hardened material are also effective in removing some natural oils present in the nails which keep them supple and prevent them from breaking. For this reason the formulated products contain oily substitute materials to maintain the condition of the nails. If you simply add solvent to thin out old polish you have no guarantee that the proportion of these oils are what the manufacturer intended. Purpose made thinners include oils.

    Soak with acetone and blot do not RUB blot with a rather damp rag. Repeat Repeat shelter turning the rag so which you're actually not putting polish decrease back on one extra spot. The acetone will disolve the polish and it is going to take up up into the rag as long as you do not smear it around. Fingernail polish remover style of works although has been made milder to be form on your cuticles so organic acetone works technique extra valuable. which you would be able to get acetone from any paint branch. basically spectacular success

    The difference between acetone and butyl acetate is that acetone is about six times more volatile so it will evaporate six times faster. It is also a much more powerful solvent.

    Commercial formulations of nail polish do not use acetone because it would evaporate quickly and the polish would thicken.
