Description

Technical Field

[0001] The invention relates to the technical field of daily cosmetics, and in particular to a water-based nail base oil and a preparation method thereof. Background Art

[0002] Manicure has become a popular beauty method for modern women, whether it is DIY at home or serviced by professional nail salons. However, while traditional oil-based nail polish and phototherapy nail gel beautify nails, they also cause considerable damage to nail health.

[0003] More than 70% of oil-based nail polish is composed of solvents such as acetone and ethyl acetate. During the film-forming process, 70% of the solvent evaporates to form a film. A large proportion of the solvent has a corrosive and irritating effect on the nail surface and the skin around the nail. At the same time, the solvent also has a significant dehydrating effect on the nail surface. When removing the nail polish, it is usually wiped off with nail polish remover such as ethyl acetate, which further dehydrates and irritates the nail surface, reduces the glossiness of the nail surface, increases brittleness, and may cause the nail to crack and break.

[0004] The main components of phototherapy nail glue are phototherapy resin and monomer. After forming the film, it has a tough texture and good strength, which is difficult to remove easily. Usually, a grinder or sanding strip is used to grind off most of the colloid, and then an acetone nail remover bag is wrapped on the colloid for about 5-10 minutes. The colloid swells after being soaked in solvent, and then a special tool is used to scrape the residual glue on the nail surface. During the whole process, under the action of solvent and mechanical force for a long time, it is inevitable that some damage will be caused to the nail surface. Under this operation, the keratin cells of the nails are damaged, the nail surface becomes thinner and soft, and stratification and fracture may occur, and even inflammation and infection of the skin at the edge of the finger may occur. In addition, nail glue is usually worn for more than 3-4 weeks, which also affects the normal metabolism and growth of the nails, making the growth rate of the nails slow down. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a water-based nail polish base oil and a preparation method thereof, which overcomes the deficiencies of the prior art and has a reasonable design. By using an aqueous emulsion as the main component, the problems of irritating odor and dehydration of the nail surface caused by the use of solvent-based nail polish during application are effectively avoided.

[0013] The present invention also discloses a method for preparing the above-mentioned water-based armor base oil, comprising the following steps: Step S1: 92% of acrylic siloxane emulsion and 0.5% of bentonite were mixed and dispersed at a rotation speed of 700-800 rpm for 20-25 minutes; Step S2: adding 0.5% of alkyl polyoxyethylene ether, 1.5% of glycerol and 0.5% of phenoxyethanol in sequence, and continuing to disperse at a speed of 700-800 rpm for 15-20 minutes; Step S3: adding 3% of acrylate copolymer and dispersing at a speed of 700-800 rpm for 15-20 minutes; Step S4: Finally, add 2% hydrolyzed soy protein, reduce the dispersion speed to 300-400 rpm, and disperse for 10 minutes; Step S5: Filter the mixture after dispersion in step S4 using a 200-mesh filter, and let it stand for 12 hours to defoam; Step S6: filling the finished product.

[0014] The present invention provides a water-based nail base oil and a preparation method thereof. It has the following beneficial effects: by using the water-based emulsion as the main component, it effectively avoids the problems of irritating odor and dehydration of the nail surface when applying the solvent-based nail polish.

At the same time, by adding a moisturizer, the stratum corneum of the nail surface will not be dehydrated, and the nail surface is guaranteed to be intact after removal. It effectively avoids the problems of whitening and brittleness of the nail surface after removal. And by adding hydrolyzed protein, the low molecular weight hydrolyzed protein penetrates and slowly deposits on the stratum corneum of the nail surface, which has a good repair and toughening effect on the rough, dry, layered, fragile and damaged nail surface.
