Description

Cosmetic composition for improving skin adhesion {Cosmetic Composition For Improving skin Adhesion}

The present invention relates to a cosmetic composition for enhancing skin adhesion.

The friction between human skin and objects (clothes, etc.) can generate electric charges over thousands of volts (V). People with atopic or dry skin can easily generate static electricity because their skin is dry.

When two objects are in contact with each other, the charge is skewed to one side, and this is called charging (a state in which charges are accumulated), and the state of this charging can be called static electricity (in a state).

In other words, static electricity is a state in which there is an imbalance between plus and minus, and is basically caused by friction between two or more insulators (a generic term for materials that have difficult to transfer electricity or heat). The polarity of minus, is determined by the combination of insulators.

On the other hand, the polarity of charging is determined by the charging sequence, and in charging between different materials, the greater the distance the charging heat is, the greater the static electricity is generated.

Here, the charging sequence can be understood as the order in which the objects in the upper sequence are charged with positive (+) charge and the objects in the lower sequence are charged with negative (-) charge when random two objects are rubbed. have.

In general, titanium dioxide and the like used in makeup cosmetics have the same positive (+) counterelectrode as the skin during charging due to friction, and since these are materials having a close positional relationship in the charging sequence, the charging amount is relatively small.

Accordingly, conventional makeup cosmetics and the like have a problem in that adhesion to the skin is lowered.
