[0001] The present invention relates to the technical field of cosmetics, and in particular to an environmentally friendly functional nail polish with Chinese herbal medicine as a main component. Background Art

[0002] With the increase in consumption levels, people's pursuit of beauty has become stronger. Although nail polish is not as common as facial cosmetics, it is also one of the cosmetics widely used by women.

[0003] Currently, nail polishes on the market primarily consist of chemical solvents, resins, plasticizers (such as dibutyl phthalate), and pigments, and may contain harmful substances such as formaldehyde and toluene. These harmful chemicals can pollute the environment, and long-term use can cause damage to nails and health, such as brittle and yellowing. Their primary function is to beautify and protect nails, not protect them, and long-term use can damage them. Therefore, a nail polish with natural ingredients, free of harmful chemicals, and possessing both protective and nourishing properties is needed to improve nail health. Summary of the Invention
