The conceptual diagram for demonstrating the makeup remover which concerns on embodiment of this invention.

The makeup remover according to the embodiment of the present invention is in a state in which a natural polymer and / or a chemical polymer is dissolved in pH value-transferring alkaline ionized water. This makeup remover is in the form of a liquid, a slurry, or a gel.
The pH value transferable alkaline ionized water as the base of this makeup remover has the effect of causing the makeup agent to float from the skin by the action of alkali ions, and the feature that the alkali irritation to the skin can be reduced by the pH value transferability. Have.
Specifically, pH value transferability refers to the property of increasing or decreasing the pH value when a substance is touched. The makeup remover according to the embodiment of the present invention shifts to neutral or skin pH value in human skin. Human skin generally has a pH value of about 4.0 to 6.5.

The pH value transferable alkaline ionized water used for the makeup removing agent according to the embodiment of the present invention is reduced to about one-sixth of a normal water molecule by a technique called weakly charged homogenization. Therefore, the makeup remover according to the embodiment of the present invention easily penetrates into the skin as shown in FIG.
Weak charge homogenization is a technology that changes the ionic properties of makeup remover (liquid) components. By changing the ionic properties, the molecules of the components repel each other to prevent binding and control the amount of change in ionic properties. By doing so, it is possible to adjust the particle size of each component.
In the present embodiment, by changing the nature of the ions of the substance, the ions are repelled and the attractive properties are hindered. For this reason, the makeup removing agent (liquid agent) can be kept in a nano-sized state (see FIG. 1).

This pH-shifting alkaline ionized water has an initial pH value of 8.50 to 9.50. The pH-shifting alkaline ionized water has an alkalinity adjusted to 2 to 3 by a 0.1N sulfuric acid titration method.
In addition, as described above, this makeup remover has a pH value of 8.50 to 9.50 at the initial stage, and when touching human skin, the pH value of human skin is gradually about 4.0 to 6.5, preferably Is configured to shift to a pH value of approximately 4.0 to 6.0.
The make-up remover, for example, comes into contact with neutral fat or glycerin contained in sweat, and binds with a bioelectric current or the like to lower the pH value, and shifts from alkaline to neutral or weakly acidic.
Here, the binding by bioelectric current means that the water molecules of alkaline ionized water have become small due to weakly charged homogenization, so that the makeup remover penetrates the skin makeup agent through the skin makeup agent, and the living body has homeostasis. It shifts to the pH value of human skin by combining with current.

  Moreover, in the makeup remover according to the embodiment of the present invention, the mineral contained in the pH value-transferring alkaline ionized water as the base contains a magnesium chloride salt.

  The hyaluronic acid Na may be, for example, an extract from chicken head, a product obtained from a microorganism (BIO), or the like, or a mixture thereof.

  The blending ratio of the hyaluronic acid Na used for the makeup remover is preferably about 0.1 to 10 wt%, more preferably 0.1 to 3 wt%.

  The carboxyvinyl polymer used for the makeup remover may be any of a low molecular type, a medium molecular type, and a high molecular type, and is preferably a low molecular type. The low molecular type carboxyvinyl polymer has a relatively large surface area, and therefore has a good reaction.

  Further, the carboxyvinyl polymer used for the makeup remover is preferably used after neutralization with an amine salt such as a triethanolamine salt or an alkali such as sodium hydroxide or potassium hydroxide before blending.

The most preferable neutralizing agent for the carboxyvinyl polymer used in the makeup remover is triethanolamine. For example, ethanolamine has the characteristics of an ammonia-based chemical substance. Specifically, monoethanolamine has a strong ammonia odor and is difficult to use in cosmetics.
Diethanolamine has a weak ammonia odor compared to monoethanolamine.
Triethanolamine is preferable for use as a cosmetic because it has the best chemical stability and almost no odor of ammonia.

  Moreover, the triethanolamine neutralized product of the carboxyvinyl polymer used in the makeup remover according to the embodiment of the present invention has a blending ratio of 0.1 to 5 wt%, preferably 0.1 to 3 wt%. For example, if the alkalinity is too strong, it may cause rough skin. For this reason, the pH value is raised by making it slightly alkaline. The alkalinity is adjusted to 2-3 by 0.1N sulfuric acid titration method.

  The make-up remover according to the first embodiment of the present invention is a mixture of 85 wt% pH-shifting alkaline ionized water, 5 wt% carboxyvinyl polymer (triethanol neutralized product), and 10 wt% sodium hyaluronate. It is made by adjusting.

  Using this make-up remover, the make-up agent was applied to each of mascara (Makiage Full Vision (BK999) manufactured by Shiseido Co., Ltd.), lipstick (Machiage Tule Rouge manufactured by Shiseido Co., Ltd.), and foundation (Makiage Lasting Stick Foundation manufactured by Shiseido Co., Ltd.).
