It was discovered that the above cosmetics could be obtained, and the present invention was completed.

[0006] That is, it is known that water is deeply related to the retention of youthful skin, and it is recognized that moisturizing the skin is one of the important functions for cosmetics. Considering the moisturization of the skin, there is a hydrophilic hygroscopic substance called natural moisturizing factor (hereinafter referred to as NMF) in the keratin, which plays an important role in moisturizing the skin,
Further, it is known that, in addition to the NMF component, mucopolysaccharides which are present in the dermis and play a role of water retention also play an important role in moisturizing the skin. Conventionally, it has been desirable to manufacture cosmetics using this natural moisturizing mechanism as a model, and substances having high hygroscopicity among these components have been added to cosmetics as moisturizers.

That is, the NMF components in the keratin of the skin include amino acids such as glycine, serine, alanine and pyrrolidone carboxylate, minerals such as potassium, sodium, calcium and magnesium, urea, sugars and organic acids. Has been. On the other hand, in natural water, calcium,
Contains various minerals such as magnesium, sodium and potassium. It is considered that these are similar not only to the types of minerals existing as NMF components in the skin but also to their existing forms. Therefore, if various moisturizing components in the NMF component, such as amino acids, are added to the cosmetic containing natural water, it is possible to obtain a cosmetic having a composition similar to that of the skin NMF.

Further, for moisturizing the skin, by adding, in addition to the NMF component, mucopolysaccharides which are present in the dermis and play a role of water retention, a cosmetic similar to the moisturizing mechanism of the skin can be obtained. It is possible. The cosmetic according to the present invention made on the basis of the above findings is characterized by containing natural water.

A moisturizing component is added to the cosmetic composition. Further, it is preferable that the moisturizing component to be blended is one kind or a combination of two or more kinds selected from polyhydric alcohols, mucopolysaccharides, NMF or cyclodextrin derivatives.
