What's in my polish?

OPI has some great new neon nail polish for sale at salons (Mod about Brights) I found $1 (much cheaper) versions at my local dollar store. This obviously requires a few more coats to get intense color but eventually does the job.

My concern, however, as I'm revelling in this great bargain is what exactly I'm putting on my nails. At what cost is this really?

My Dollar Store Nailpolish (made in the US):

Toluene & Formaldehyde Free (both cancer causing)
Ethyl Acetate - common solvent used in paints, perfumes. Known irritant and hormone disrupter. Used to decaffeinate coffee et al.
Dibutyl Phthalate - Dangerous to environment and unborn babies. All major producers stopped using in 2006 although there are many organizations that claim its safe for humans. Banned for use in cosmetics by European Union although phthlates are used in many other industries.
Camphor - On Health Canada's 'Hotlist' of Prohibited or Restricted Cosmetic Ingredients for hazards to children
Benzophenone-1 - UV Blocker used in many cosmetics. Approved for use although proven to be highly toxic and negative effects on brain, organs and nervous system.
Other ingredients include color and finishes.

Conclusion:
Although nail polish is horribly toxic, I learned that many of the ingredients are in hundreds of other products that we're exposed to. I also learned that cheaper polishes are not necessarily more full of chemicals as one might think.
When choosing polish, stay away from toluene & formaldehyde. Try new products with mineral colorants. And if you care enough, you can find natural nail color at stores in Toronto like Noah's or at Carrot Common on the Danforth.
