• Nail Polish Ingredients: Nail polish typically contains nitrocellulose, which is a film-forming polymer that is the main ingredient in most nail polishes. It also contains plasticizers such as diethylphthalate, dibutylphthalate, and camphor to yield non-brittle films. Dyes and pigments are added to provide color, such as chromium oxide greens, chromium hydroxide, ferric ferrocyanide, stannic oxide, titanium dioxide, iron oxide, carmine, ultramarine, and manganese violet. Opalescent pigments such as mica, bismuth oxychloride, natural pearls, and aluminum powder can be added to provide a glittery or shimmer look. Some nail polishes may contain harmful chemicals such as chromium(III) oxide green and Prussian blue, which have shown evidence of going through chemical degradation that could have a detrimental effect on health.

• Green Nail Health: Green nails can be caused by a bacterial infection known as green nail syndrome, which is characterized by a greenish discoloration of the nail plate. This condition is usually caused by Pseudomonas aeruginosa, a type of bacteria that thrives in moist environments. Treatment involves keeping the affected area clean and dry, and in severe cases, antibiotics may be prescribed.

In summary, green and gold nail designs can be achieved using various nail polish products and techniques. It is important to choose products that are safe and free from harmful chemicals, and to maintain good nail health to prevent infections and discoloration.
