Is sinful colors one of the best celling nail polish of America?

Answer 1

It is, but it shouldn't be.

It sells as well as it does because it's only a couple of dollars a bottle, so you can afford to buy a bottle of it for a special occasion and throw it in the back of the nail polish shelf after you use it. You're not going to do that with OPI at $8.50 per bottle.

There are two problems with it: it's not very good, for one. You've got to put many coats of it on your nails to get it to work. And it doesn't seem to hold up as well as more expensive polishes, but for two bucks what do you expect?

The real problem is what's in it: collodion and dibutyl phthalate (DBP). ALL nail polish, no matter where it's from, contains nitrocellulose, which is the plastic that stays on your nails after the solvents dry. You can buy it two ways: as a powder which you dissolve in ethyl acetate, or already dissolved in ethyl acetate and ether, which is called collodion. Collodion is a health hazard because of the ether. Cheap polishes like Sinful Colors use collodion because it reduces the cost of manufacturing the product--you don't have to wait for the nitrocellulose to dissolve before adding the rest of the ingredients. The other is dibutyl phthalate, which is suspected of being both an endocrine system disruptor (screws up your hormone system) and a teratogen (causes birth defects). No one else puts DBP in their nail polish, and for this reason alone I wouldn't recommend it.

Sally Beauty stores carry "Finger Paints" brand, which is also an inexpensive polish but it's DBP-free and contains nitrocellulose rather than collodion. I would get that. I tried a bottle and it works okay.
