Highly effective cosmetics.

[0002]

2. Description of the Related Art Various moisturizers are used in cosmetics for skin and hair in order to retain moisture, suppress the feeling of dryness and dryness, and give a moist feeling. Such moisturizers include trehalose, glucose, sorbitol,
It is well known that sugars such as maltose and maltitol, or reduced forms thereof, can be used alone or in combination of two or more in cosmetics.

[0003]

However, a cosmetic composition containing trehalose alone has a moist feeling and spreadability at the time of application, and a cosmetic composition containing glucose and maltose alone has a moist feeling and stickiness. And it wasn't very satisfying. An object of the present invention is to provide a highly moisturizing cosmetic which spreads well and does not have a sticky feeling when applied, and gives the skin and hair tension and moisture.

[0004]
