Nail colors are one of the little beauty secrets that we all have in our make up bags; but nail colors are made up of chemicals that are not good for the environment as we remove the color with nail enamel removers and discard the colors into trans cans that soon find their ways to land fills. The removers themselves are chemical composition and when you put together all the discards of nail polish users all over the world, you are left with a big environmental mess. 
Eco friendly nail polishes have very strong colors and are greener than the ones that are made out of chemicals; they are also available in a number of colors and are chip prone as well.
A number of the big cosmetics brands are coming up with nail enamel formulas that are free from the phthalates and the carcinogens that make the nail colors safe for manicurists and for their consumers as well. The following brands are safe enough for children to use and have an array of colors;
