Description

Technical Field

[0001] This application relates to the field of cosmetics-nail polish preparation technology, and in particular to a peelable, quick-drying water-based nail polish and its preparation method. Background Technology

[0002] Water-based nail polish has a shorter lasting time compared to regular oil-based nail polish; in fact, its tendency to chip easily actually indicates it's healthier and less damaging to the nails. Chemical nail polish achieves its superior adhesion because it corrodes the nail's surface layer, embedding the color deep within the nail. This not only damages the nail cuticle but also poses a potential health risk of cancer. Therefore, the future consumer trend leans towards water-based nail polish. Water-based nail polish is made with water and acrylic emulsion as its base. It has a thinner, more fluid texture, but is easier to apply evenly. Before it dries, water-based nail polish can be easily rinsed off with water, and after drying, it forms a film that adheres to the nail surface. Currently, water-based nail polish technologies have the following drawbacks: a relatively slow drying and film-forming speed, and difficulty in easy application. Summary of the Invention

[0003] In order to address the following deficiencies in water-based nail polishes in related technologies, this application provides a method for preparing a peelable, quick-drying water-based nail polish.

[0004] Firstly, the peelable, quick-drying water-based nail polish provided in this application is achieved through the following technical solution:

[0005] A peelable, quick-drying water-based nail polish is mainly prepared from the following raw materials in parts by weight: 24-28 parts water-based film-forming agent, 1-2 parts thickener, 1.6-2.4 parts filler, 0.4-0.8 parts colorant, 0.8-1.0 parts preservative, 0.3-0.6 parts skin conditioning agent, and 70-74 parts deionized water.

[0006] The water-based nail polish provided in this application not only has the advantages of quick drying and good peelability, but also does not easily leave residue after peeling, and the nails are easy to clean.

[0007] Preferably, the aqueous film-forming agent comprises an aqueous polyurethane emulsion and an aqueous acrylate emulsion, wherein the mass ratio of the aqueous polyurethane emulsion to the aqueous acrylate emulsion is controlled at 100:(8-10); the solid content of the aqueous polyurethane emulsion is 30-45%; and the solid content of the aqueous acrylate emulsion is 40-52%.

[0008] By adopting the above technical solution, the bonding strength between nail polish and nail can be adjusted to a moderate level, which can avoid excessive stickiness that makes it difficult to peel off and clean, and also avoid low bonding strength that makes nail polish easy to fall off.

[0009] Preferably, the aqueous polyurethane emulsion is mainly composed of isophorone diisocyanate (IPDI), chain extender, polyol, catalyst, leveling agent, acetone, dimethylethanolamine, and deionized water; the chain extender is composed of 1,6-hexanediol, 1,6-hexanediamine, and 2,2-bis(4-aminocyclohexyl)hexafluoropropane; the molar ratio of 1,6-hexanediol, 1,6-hexanediamine, and 2,2-bis(4-aminocyclohexyl)hexafluoropropane is controlled at 1:1:(0.03-0.08); the polyol is composed of polytetrahydrofuran ether diol with a molecular weight of 2000-3000 and bio-based modified polyol with a molecular weight of 2000-3000. The product is composed of an ester polyol and a dihydroxy-terminated silicone with a molecular weight of 5000-10000; the molar ratio of the polytetrahydrofuran ether diol, the bio-based modified polyester polyol, and the dihydroxy-terminated silicone is controlled at 1:(2-4):(0.04-0.12); the bio-based modified polyester polyol is a palm oil modified polyester polyol with a molecular weight of 1000-3000; the catalyst is organic bismuth; the molar amount of -NCO in the isophorone diisocyanate IPDI is 0.985-0.998 times the total molar amount of active functional groups in the chain extender and polyol; the molar ratio of the chain extender to the polyol is controlled at (2-3):1;

[0010] The preparation method of the waterborne polyurethane emulsion is as follows: 40-60% of the total mass of polyol, 40-60% of the total mass of isocyanate, and 20-40% of the total mass of catalyst are accurately measured and mixed evenly. The remaining polyol, isocyanate, and catalyst are added at 200-300 rpm and mixed for 5-10 minutes. The temperature is raised to 85-90℃ and reacted for 2 hours. After adjusting the temperature to 80℃, a chain extender, a leveling agent, and 40-60% of the total mass of acetone are added. After reacting for 2 hours, the remaining acetone is added to adjust the viscosity to 5000-8000 mPa·s. The temperature is lowered to 40-45℃, and dimethylethanolamine is added for neutralization. Then, deionized water is added and subjected to high-speed shearing for 30-40 minutes. Acetone is removed by distillation to obtain the finished waterborne polyurethane emulsion.

[0011] The aqueous polyurethane emulsion prepared in this application exhibits good flexibility, ensuring that the cured nail polish is not easily peeled off and leaves residue, resulting in superior nail cleaning performance. The use of bio-based materials in this application improves the affinity between nail polish and the nail cuticle, effectively reducing the damage caused by nail polish to the nail cuticle. Furthermore, the preparation method of the aqueous polyurethane emulsion provided in this application is relatively simple, easy to operate, and facilitates industrial-scale production.

[0012] Preferably, the filler is composed of surface-modified silica and mica powder; the mass ratio of silica to mica powder is controlled at 100:(35-50).

[0013] Preferably, the filler is prepared as follows: the accurately measured filler is activated at 120-18℃ for 2-4 hours, the activated filler is naturally cooled to room temperature, and then placed in a surface modification treatment solution and ultrasonically treated at 300-500 rpm for 30-40 minutes. After draining, it is dried at 40-60℃ until the moisture content is less than 0.5% to obtain the finished filler. The surface modification treatment solution is mainly prepared from the following raw materials: 100 parts of deionized water, 3-5 parts of γ-methacryloyloxypropyltrimethoxysilane, and 1-2 parts of isopropyl triisostearoyl titanate.

[0014] By adopting the above technical solution, the compatibility of fillers and film-forming aids can be improved, thereby improving the mechanical properties of the formed nail coating film and making it less prone to peeling and leaving residue, and improving the nail's easy-to-clean properties.

[0015] Preferably, the skin conditioning agent includes a first skin conditioning agent and a second skin conditioning agent, and the mass ratio of the first skin conditioning agent and the second skin conditioning agent is controlled at (28-35):(8-12).

[0016] Preferably, the first skin conditioning agent is composed of water, hydrolyzed wheat protein, phenoxyethanol, and butylene glycol; the second skin conditioning agent is composed of Euglena gracilis polysaccharide and hydrolyzed collagen.

[0019] Secondly, the method for preparing a peelable, quick-drying water-based nail polish provided in this application is achieved through the following technical solution:

[0021] S1, Preparation of fillers and aqueous film-forming agents;

[0022] S2, weigh out the same amount of filler, aqueous film-forming agent, thickener, filler, colorant, preservative, skin conditioning agent, and deionized water, for later use;

[0025] S5. Take a sample and send it to the quality control department for testing. After passing the test, filter the sample through a 100-200 mesh screen to obtain the finished product.

[0026] The preparation method of the water-based nail polish in this application is relatively simple, easy to operate, and easy to realize industrialized production, reduce production costs, and enhance market competitiveness.

[0027] In summary, this application has the following advantages:
