A nail polish set typically includes a variety of colors and finishes. Here is some information about nail polish ingredients, positive and negative aspects, and materials:

Ingredients:

• Solvents: Solvents are the carriers of the other ingredients and help the nail polish flow smoothly. Commonly used solvents include ethyl acetate, acetone, and N-butyl acetate.

• Film formers: These ingredients ensure that nail polishes dry hard and shiny. Nitrocellulose and cellulose acetate butyrate are commonly used film formers.

• Plasticizers: These provide flexibility and adhesion to the nail polish. Common plasticizers include dibutyl phthalate, triphenyl phosphate, trimethyl pentanyl diisobutyrate, and camphor.

• Resins: Resins improve adhesion, hardening, and gloss. Common resins include tosylamide/formaldehyde resin, tosylamide/epoxy resin, formalin, methylene glycol, and tolunesulfonamide/formaldehyde resin.

• Pigments: Pigments provide color to the nail polish. Common pigments include iron oxides, color lakes, mica, and other FDA-approved colorants.

Positive aspects:

• Some nail polish brands are "9-free," meaning they do not contain certain toxic chemicals such as dibutyl phthalate, formaldehyde, and toluene.

• Non-toxic and eco-friendly nail polish brands are available that are made without preservatives or acetates, both of which release low levels of volatile organic compounds (VOCs) that can cause headaches and respiratory problems.

Negative aspects:

• Nail polish is known to be a household hazardous waste due to its toxic ingredients.

• Some nail technicians working in nail salons may be exposed to dust, vapors, and other nail product ingredients at significant levels over extended periods, which can pose safety concerns.

Materials:

• Nail polish ingredients are generally synthetic organic materials and inorganic chemical products that are generated through a series of chemical reactions.

• The raw material production of nail polish requires a significant amount of energy, which is usually provided by factories and power plants.

In conclusion, nail polish sets typically include a variety of colors and finishes. Nail polish ingredients include solvents, film formers, plasticizers, resins, and pigments. Some nail polish brands are "9-free" and non-toxic, while others contain toxic chemicals that make them household hazardous waste. Nail polish ingredients are generally synthetic organic materials and inorganic chemical products that require a significant amount of energy to produce.
