Problems solved by technology

[0002] Common nail polishes currently on the market use nitrocellulose as a film-forming agent, phthalates as plasticizers, and acetone and ethyl acetate as solvents. The main defect is that nitrocellulose as a nail polish film-forming agent is flammable and Explosive dangerous goods, the production and use of engineering are very dangerous; plasticizers such as phthalate esters will affect human fertility and endanger human health; acetone and ethyl acetate are used as solvents, which have certain toxicity and irritation; nails After the oil is applied, if you want to remove it, you must use nail polish remover containing a variety of organic solvents to wipe it off. It is inconvenient to use, and regular nail polish removal will endanger your health.
[0004] Patent application CN1260167A uses nitrocellulose as a film-forming agent. Although nail polish with good film-forming properties and wear resistance can be obtained, nitrocellulose is flammable and explosive, and the storage and use process is dangerous, which is not conducive to sustainable development.
Patent application CN102397198 A uses ethyl acetate, acetone, etc. as solvents. This type of formula can be properly formulated to obtain nail polish with high gloss, strong adhesion and strong water resistance, but it has the following disadvantages: 1. It has a pungent smell and is strongly pungent Inhalation of the smell will cause physical discomfort; 2. After use, it will be more irritating to the nails and skin of the human body, and will cause greater damage to long-term use; 3. Contact with chemical fiber clothing and general plastics will cause dissolution corrosion
This type of formula can be properly formulated to obtain nail polishes with low odor, low irritation, high gloss, and no corrosion to chemical fiber clothing and plastics, but there are the following disadvantages: 1. Poor water resistance and easy to fall off when exposed to water; 2. Adhesion No, there is a big gap compared with organic solvent-based nail polish
But the peeling time of the nail polish is different under different water temperature conditions, and the user does not know when is the best peeling and clearing time, which will cause a waste of time for the user and is quite inconvenient

Embodiment 1

[0017] First make methyl orange into 1g / L aqueous solution, then add 0.5ml methyl orange solution into 20ml ethanol, then add dropwise 1mol / L ethanol solution of sulfuric acid until methyl orange turns red. Then add 2g of film-forming agent PVB into the above solution, and stir until it is completely dissolved. Then add 0.2g of nano-sized silicon dioxide as a filler, stir for 10 minutes, then add 0.1g of pearl powder, stir for 30-40min, and finally add 0.2g of film-forming agent PVP, and stir for 20 minutes to obtain red nail polish.

[0018] Apply the red nail polish to the nails. After it is completely dry, immerse your fingers in tap water and peel off completely after the nail polish turns yellow.

Embodiment 2

[0020] First dissolve 1g of bromophenol blue in 1L of water: ethanol = 8:2 (volume ratio) solution, then add 0.5ml of bromophenol blue solution to 20ml of ethanol, then add dropwise the ethanol solution of 1mol / L sulfuric acid until bromophenol blue turns yellow. Then add 2g of film-forming agent PVB into the above solution, and stir until it is completely dissolved. Then add 0.2g of nano-sized silicon dioxide as a filler, stir for 10 minutes, then add 0.1g of pearl powder, stir for 30-40min, and finally add 0.2g of film-forming agent PVP, and stir for 20 minutes to obtain yellow nail polish.

[0021] Apply the yellow nail polish to the nails. After it is completely dry, immerse your fingers in tap water and peel off completely after the nail polish turns blue.

Embodiment 3

[0023] First prepare the Congo red into a 1g / L aqueous solution, then add 0.5ml of the Congo red solution to 20ml of ethanol, and then add dropwise a 1mol / L sulfuric acid ethanol solution until the Congo red appears purple. Then add 2g of film-forming agent PVB into the above solution, and stir until it is completely dissolved. Then add 0.2g of nano-scale silica as a filler, stir for 10 minutes, then add 0.1g of pearl powder, stir for 30-40min, and finally add 0.2g of film-forming agent PVP, and stir for 20 minutes to obtain purple nail polish.

[0024] Apply the purple nail polish to the nails. After it is completely dry, immerse your fingers in tap water and peel off completely after the nail polish turns red.

Abstract

The invention provides nail polish capable of indicating stripping time and easy to remove. The nail polish is prepared from an acid-base indicator solution, ethanol, a proper quantity of a color developing agent solution, filler, pearl powder, a film-forming agent PVB and a film-forming agent PVP. According to a preparation method, the acid-base indicator solution is prepared firstly and then added into ethanol, pH is regulated with an ethanol solution of a color developing agent, and an indicator is made to develop color; the film-forming agent PVB is added into the solution, and the mixture is stirred to be completely dissolved; the filler is added, the mixture is stirred to be uniform, the pearl powder is added, the mixture is stirred to be uniform, the film-forming agent PVP is added lastly, the mixture is stirred to be uniform, and the nail polish is prepared. The preparation method is simple, the nail polish is safe in use, a plasticizer harmful to a human body is not contained, a toxic, low-toxicity and irritant solvent is not used, harm to the body can be reduced obviously, and nanoscale silicon dioxide enables the nail polish to have a certain ultraviolet resisting function. Particularly, the nail polish has the function of indicating stripping time and is convenient for people to clean and change.
