Although it has a high moisturizing effect, its high molecular weight has extremely low permeability to the skin DIK, and therefore it has cosmetic effects and anti-aging physiological effects (improving rough skin, improving keratin).
cannot be sufficiently expressed. The behavior and properties of high molecular weight hyaluronic acid (food) in an aqueous phase system are similar to those of low molecular weight hyaluronic acid (salt) described below.For example, hyaluronic acid with an average molecular weight of 1 million Sodium acid aqueous solution (
It is well known that the viscosity of 0.1% (concentration) decreases by half after one month of use (Japanese Unexamined Patent Publication No. 185208/1983, page 2). Furthermore, water-based cosmetics in which high-molecular hyaluronic acid (salt) is dissolved give an unpleasant feel such as stickiness and stiffness to the body, and when stored for a long period of time, they exhibit extremely low viscosity and F9.
It has some marking defects. In order to improve these difficulties, Japanese Patent Application Laid-open No. 185208/1983 proposed polyamino acid l

A product formulation containing sodium hyaluronate, which is used in combination with hyaluronic acid (salt), but has been sufficiently improved that the ratio between the two ratios of sodium hyaluronate ranges from 03 to 2:1. However, since it uses high molecular weight sodium hyaluronate, it gives the skin an unpleasant feeling such as stickiness, and its permeability into the skin is not sufficient, and it does not have the effect of improving rough skin or keratin. Improvement effect, storage stability 4f4
/I! 'It has been certified. (Note that Japanese Patent No. 57-212108 does not specifically disclose experimental results regarding the effects of such compositions or cosmetics containing low-molecular-weight 5I hyaluronic acid (salt).) In addition, the high molecular weight hyaluronic acid (salt) mentioned above has low stability, such as coloration by ultraviolet rays and formation of precipitates in the coexistence of cationic electrolytes (cationic surfactants, etc.), and Easy manipulation from biological samples [%/cases]
It has many drawbacks, such as high production costs because it requires a lot of water to extract. As a result of intensive research into natural power supply, the structure and characteristics of electrolyte, and its application to cosmetics, the present inventors found that (1) Cylinder with a molecular weight of 10,000 to 100,000 and an average molecular weight of 20,000 to 80,000; The behavior and characteristics of hyaluronic acid and its salts in an aqueous phase system and in aqueous cosmetics are significantly inconsistent with those of high molecular weight hyaluronic acid (salts) in the prior art. (2) The above-mentioned specific Low molecular weight hyaluronic acid (salt),
Although it has a low molecular weight, it has an excellent ability to form a film on the skin surface, and even if the film formed is thick, it does not cause any strange sensations such as tightness on the skin. Also, the specific low molecular weight hyaluronic acid (salt) has high permeability into the stratum corneum (3) because of its low viscosity, it does not give a sticky feeling to the skin and can be used in large amounts in aqueous cosmetics. (4) the specific low molecular weight hyaluronic acid (salt);
It is chemically and physically stable, has low viscosity and does not cause coloration due to ultraviolet rays, and water-based cosmetics containing it have excellent storage stability. (5) When the aqueous cosmetic containing the specific low molecular weight hyaluronic acid (salt) is applied to the skin, it exhibits a so-called cosmetic effect on the skin that makes the skin fine, glossy, and beautiful. (6) Cosmetics containing the specific low-molecular-weight hyaluronic acid (salt) are safe, do not come off the skin, and have excellent effects on improving rough skin and improving keratin.The present invention was completed after discovering the following.
