Nail polish is a cosmetic product that is used to decorate nails and comes in a variety of colors and shades. Nail polish typically consists of an organic polymer and several other components that give it colors and textures. The ingredients in nail polish can vary depending on the brand and type of polish. Here are some common ingredients found in nail polish:

Positive:

• Film formers: These ingredients ensure that nail polish dries hard and shiny. Examples include nitrocellulose and cellulose acetate butyrate.
• Pigments: These provide color to the nail polish. Pigments can be organic or inorganic. Examples of organic pigments include those derived from petrochemicals, while inorganic mineral pigments include iron oxides.
• Solvents: These are the carriers of the other ingredients and help the nail polish flow smoothly. Examples include ethyl acetate and isopropyl alcohol.
• Plasticizers: These provide flexibility and adhesion to the nail polish. Examples include triphenyl phosphate and trimethyl pentanyl diisobutyrate.
• Resin: This ingredient improves adhesion, hardening, and gloss. Examples include tosylamide/formaldehyde resin and tosylamide/epoxy resin.
• UV stabilizer: This ingredient prevents colors from fading. An example is benzophenone-1.

Negative:

• Some nail polishes contain toxic chemicals such as dibutyl phthalate (DBP), formaldehyde, and toluene. However, many brands now offer "non-toxic" or "9-free" nail polishes that do not contain these chemicals.
• Some ingredients in nail polish, such as coal tar dyes, have unclear safety profiles.
• The exact amount of absorption of nail polish chemicals into the body and whether it has negative health effects are not well established.

In summary, nail polish ingredients can vary depending on the brand and type of polish. Many nail polishes now offer non-toxic options that do not contain certain toxic chemicals. While some ingredients in nail polish have unclear safety profiles, the exact amount of absorption of nail polish chemicals into the body and whether it has negative health effects are not well established.
