Abstract
In order to maintain good health of human skin and hair, moisture contained in them is indispensable. In the same manner moisture in nail is considered to play an important role.
Thus, using human nail sections, a series of model experiments was performed, which clarified that moisture in nail has a great effect on its physical properties. As the result it was confirmed that supplement of moisture to nails is an essential condition to keep nails in good health. Therefore, the authors have started development of a nail enamel containing moisture, which has never been brought into the market.
The W/O emulsion-type nail enamel, in which a new mode of emulsification has been employed, not only contributes to keep nails in good health but it is also equal to conventional solvent-type nail enamel in every respect.
