Although the present invention is a single solution consisting of two layers, (i)
In addition to the function of cleaning the nail surface before applying nail lacquer, and (ii) the removal function when removing nail lacquer.
(iii) Concerning a nail polish remover that can perform oil replenishment treatment functions independently. Conventionally, nail lacquer nail polish removers mainly contain ketones such as acetone, methyl ethyl ketone, etc. to dissolve nitrocellulose-based nail lacquer.
It has been composed of acetate esters such as ethyl acetate and butyl acetate, ethyl cellosolve, etc. as a base material, and various organic solvents as diluents. however,
Contrary to the nail removal action, which is the main function of nail polish remover, its dissolving power also excessively extracts and removes not only the nail surface but also the oil and moisture necessary for nail physiology within the nail plate, making the nail glossy. There were negative effects such as loss of nails and brittle nails. For this reason, nail polish removers currently on the market prevent damage to the nails to some extent by adding a small amount of oil and water, but there is still no product with sufficient treatment effects. In other words, if you carelessly increase the amount of oil in the hopes of getting a sufficient treatment effect, the dissolving power of the nail polisher will deteriorate, reducing the nail polish removal effect, and at the same time, excess oil will remain on the nail surface after polish removal, making it difficult to feel. Not only is this not good for the nail polish, but it also causes problems such as the nail lacquer being repelled by the oil and not being able to be applied evenly. On the other hand, an inadvertent increase in water content not only reduces the light removing effect but also tends to cause precipitation and separation of oil, resulting in an unfavorable appearance. In this way, the removers currently on the market are oil-based and
There was a natural limit to increasing water intake at the same time. Therefore, products that need to be actively promoted as having treatment effects are provided on the market as treatment fees separately from nail polish removers. Therefore, conventionally
(1) When using it to remove excess oil and dirt from the nail surface to prepare the base for nail lacquer application (cleansing action), and when removing the nail lacquer coating that is no longer needed, (2) In order to obtain an emollient effect on the nails after removing the nail polish, you must use a nail treatment agent in the form of a cream, emulsion, lotion, oil, jelly, etc., which is separately purchased.(1 ) and (2)-2
It was a lot of work. Therefore, although the present invention is a single solution, it can be used for three different purposes: (i) Nail surface cleaning, (ii) Nail removal, and (iii) Treatment.The main component is acetone. , water, and oil, and is characterized by containing 0.5 to 10.0% by weight of oil in an acetone aqueous solution having a weight ratio of acetone:water = 95:5 to 80:20. The present invention will be explained in detail below based on examples. The nail polish remover of the present invention mainly contains acetone, water, and oil. In general, ketones are used as a type of solvent to dissolve nail lacquer mainly composed of nitrocellulose, but in the present invention, the nail polish remover is made into a single solution consisting of two layers, taking into account its affinity with water. Use acetone. The ratio of acetone to water is preferably about 80 to 95% by weight of acetone and about 20 to 5% by weight of water. If there is too much acetone, the ability to dissolve the oil component will increase, and the nail polish remover will not separate into two layers. On the other hand, the action of dissolving nail lacquer is mainly due to acetone, so if the amount of acetone is too small and the amount of water is too high, the ability to dissolve nail lacquer will decrease. Next, in order to add a treatment function of oil replenishment to the nail polish remover itself, it contains about 0.5 to 10.0% by weight of oil based on the acetone aqueous solution. If the oil content is too low, the treatment effect will be insufficient, and on the other hand, if the oil content is too high, the effect of dissolving the nail lacquer will decrease and the nail lacquer will remain on the nail surface, which is not preferable. Furthermore, since the oil component will precipitate in the acetone aqueous solution system, its specific gravity needs to be larger than that of the acetone aqueous solution. For example, in the case of a 95% acetone aqueous solution, the specific gravity of the oil content is 0.80 or more,
For 90% acetone aqueous solution, it needs to be 0.82 or more, and for 80% acetone aqueous solution, it needs to be 0.85 or more. At the same time, it is also necessary that the solubility in 100 ml of acetone aqueous solution is 5 g or less at room temperature. Suitable oils include octyldodecyl oleate, octyldodecyl myristate, jojoba oil, glyceryl triisostearate, olive oil, and castor oil transesterified. By selecting the oil base material used, the oil separated into the lower layer can have a spherical, ellipsoidal, or trapezoidal appearance. If necessary, in order to stabilize the shape of the precipitated oil, the layer-separated oil can be prevented from oxidizing by adding an antioxidant such as dibutylhydroxytoluene or γ-tocopherol. Furthermore, the acetone aqueous solution in the upper layer or the precipitated oil in the lower layer can be colored, respectively, so that the layer separation can be clearly distinguished. To color the upper liquid layer of acetone, water, and dissolved oil, a water-soluble colorant such as Red No. 227 or Blue No. 1 may be used. In addition, to color the sedimented oil in the lower layer, it is recommended to use an oil-soluble colorant such as Green No. 202 or Orange No. 201. In addition, in order to stabilize the coloration, it is recommended to add UV-cutting agents such as urocanic acid, ethyl paraoxybenzoate, 2-2'-4 tetrahydroxybenzophenone, ethylene glycol salicylate, and methyl 2.5 diisopropyl cinnamate. I can do it. Furthermore, in order to further stabilize the shape of the oil in the lower layer separated into two layers, sodium chloride,
It is possible to utilize the salting-out effect and specific gravity adjustment effect of the system by adding salts such as potassium chloride, sodium citrate, sodium hydrogen phosphate, and potassium hydrogen phosphate. As described above, the nail polish remover according to the present invention forms a two-liquid layer in which the oil content is precipitated when left standing. When this is gently shaken, the precipitated oil becomes finely divided into oil droplets and dispersed. Furthermore, if the container is gently turned upside down from a standing state, the settled oil will quietly settle and collect at the mouth of the container. The nail polish remover of the present invention can be used in the following three ways by utilizing the above-mentioned layered state. When removing unnecessary nail enamel, that is, removing nail enamel, if you want to remove nail enamel quickly, gently tilt the container while it is still standing.
An appropriate amount of the (dissolved oil)-(water)-(acetone) solution system 1 in the upper liquid layer is impregnated into cotton 4 or the like for use (see Figure 1). During normal light removal, shake the container lightly.
The oily liquid layer that has settled to the bottom of the container is dispersed throughout the solution as minute oil droplets 3, and used by impregnating a cotton pad 4 or the like with this. In this case, a relatively large amount of oil dissolves with excess oil, wax, etc. on the nail surface and performs a cleansing action, making it possible to remove nails with a more preventive effect than in the above case (see Figure 2). ). In addition, if it is necessary to replenish the oil to maintain the emollient properties of the nails, gently turn the container upside down while holding the opening of the container with a tip 4 or the like while it is still standing, so that the precipitated oil 2 will be absorbed from the opening of the container. The oil that settles down gently and becomes large oil droplets is used by impregnating it into cotton 4 etc. (see Figure 3). In this case, since the sedimented oil is selectively extracted, it can be used as a nail treatment by applying it to the nails with a light pine surge. At this time, some (water)-(acetone) system is also mixed in, but this is only useful for removing some dirt on the nail surface and does not impair the emollient effect on the nail. As explained above, the nail polish remover according to the present invention has the function of allowing the user to freely select rapid and strong nail removal, normal nail removal, or nail treatment according to the user's request. Here, after using the nail polish remover, it is necessary to restore the nail polish remover to the above-mentioned two-layer state immediately so that the above three methods can be used at all times. That is, when a sample is shaken once for normal light removal, the minute oil droplets become dispersed, but this uniformly dispersed state lasts for about 1 minute or more, and the sample is returned to a stationary state. In such cases, it is desirable to maintain the separated layer state within about one hour. In addition, if the coalescence and sedimentation of oil is extremely rapid, a sufficiently homogeneous system cannot be impregnated into cosmetic aids such as cotton pads and paper, resulting in a similar effect to rapid light removal. I get used to it. On the other hand, if the uniformly dispersed state lasts for a long time, the oil will remain dispersed again when you want to use it for rapid light removal or treatment, and the oil will not be sufficiently effective for the purpose of use. Since there are some things that cannot be done, it is desirable that it takes less than about an hour to return to the same state as when it was left standing. Generally, when water is added to an acetone solution in which oil is dissolved, at some point the oil that was excluded due to the affinity between water and acetone will separate. When the amount of water added is small,
The separated oil component occupies a very small amount, and it cannot be said to be a two-liquid phase separation type, and the lower layer in a stationary state cannot be selectively extracted and used as a treatment material. On the other hand, if the entire amount of oil is separated and precipitated, there is a risk that a considerable amount of oil will be removed from the nail when the user carelessly uses the upper layer or when he/she desires rapid nail removal. I don't like it. The present invention has been made through experiments to determine the suitable composition range of acetone:water:oil so as to provide an emollient effect to the nails and simultaneously act as a treatment agent and a nail polish remover. As a result, a two-liquid layer separation type nail polish remover with good appearance was obtained. Next, examples of the present invention will be shown. Regarding the nail polish removers ○A, ○B, and ○C of the present invention having the composition ratios shown in Table 1, and the conventional nail polish removers A, B, and C (i) rapid light removal, (ii) normal light removal , (iii) Comparing the various effects of each treatment action, the second
The results in the table were obtained. As is clear from these results, the nail polish remover of the present invention has (i) rapid nail removal, (iii) remarkable effects in treatment action that cannot be obtained with conventional nail polish removers, and (ii) normal nail removal. It can be seen that it also shows excellent effects.
