Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mixture of glycine betaine, pyrrolidonecarboxylic acid or a salt thereof, and a mixture of two or more kinds of amino acids selected from amino acids and salts thereof, which is excellent in hygroscopicity and moisturizing property, and is compatible with skin. The present invention relates to a cosmetic which is good, has less stickiness, and gives skin and hair tension and moisture.

[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. As such a moisturizing agent, it is well known that glycine betaine, pyrrolidonecarboxylic acid or a salt thereof, and amino acids are used alone in cosmetics (JP-A-6-293625 and JP-A-56-71020). Gazette).

[0003]

However, a cosmetic composition containing glycine betaine alone is familiar to the skin, and a cosmetic composition containing pyrrolidonecarboxylic acid or a salt thereof alone is sticky. Cosmetics containing amino acids alone were not sufficiently satisfactory in terms of moisturizing properties. The purpose of the present invention is to have no stickiness during coating,
It is an object of the present invention to provide a highly moisturizing cosmetic composition that is well familiar to the skin and has a moist feeling, and that imparts tension and moisture to the skin and hair.
