Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic composition containing yeast and / or a yeast extract and natto extract as essential components, and further containing xanthan gum and / or pullulan, which is useful for moisturizing the skin and is useful. The present invention relates to new cosmetics. That is, the object of the present invention is to activate the metabolism of the skin, to impart elasticity and flexibility of the skin, to prevent dryness and rough skin, and to protect the skin and retain water, and to improve the skin. It is to provide cosmetics having an effect.

The present invention relates to a non-woven fabric-impregnated cosmetic used as a sheet-shaped pack cosmetic, and more specifically,
The present invention relates to a non-woven fabric-impregnated cosmetic material which does not drip from the non-woven fabric and has a high moisturizing effect.

[0003]

2. Description of the Related Art Conventionally, cosmetics have been used for the purpose of preventing dryness of the skin, which is one of its important functions, and moisturizing and keeping the skin healthy. The proper water retention of the skin is essential for the normal functioning of the skin. Therefore, from these viewpoints, development and research of cosmetics and moisturizers having a high skin moisturizing effect have been made for the purpose of maintaining and improving the moisturizing property of the skin, and consumers have strongly demanded them.

[0004] Conventionally, it has been known to use yeast's moisturizing effect or skin cosmetic effect for incorporation into cosmetics and the like.
For example, Japanese Patent Publication Sho-39 which uses yeast cells themselves as a pack.
-4899, and Japanese Patent Application Laid-Open No. 5 (1994) -58242 using yeast as a cleaning agent.
3-2507 and Japanese Patent Laid-Open No. 53-2508.

The non-woven fabric-impregnated cosmetic is a cosmetic in which the composition of a formulation particularly suitable for it is impregnated in the absorber, and by coating it on the skin, it exerts an excellent occlusive effect on the skin. However, it can easily and effectively tighten the slack of the skin, give a refreshing feeling, and smooth the skin, and it is an important role in maintaining the health and beauty of the skin. Plays.

As a composition having a formulation suitable for a non-woven fabric-impregnated cosmetic, Japanese Patent Laid-Open No. 10-279429 containing a water-soluble polymer and a polyhydric alcohol as main components is well known.

Further, mucopolysaccharides such as hyaluronic acid have been widely used in cosmetics because they have a softening action on skin and an action to promote moisturization of the skin (Japanese Patent Publication No. 33-500, Japanese Patent Publication No. 55-Japanese Patent Publication No. 55-
160712, Japanese Patent Publication No. 64-7043).

Further, as a cosmetic containing mucopolysaccharide and an external preparation for skin, it contains yeast and / or a yeast extract and mucopolysaccharide as essential components, and further contains a specific plant extract and / or
Or, a cosmetic containing a specific microbial-produced polysaccharide (Japanese Patent Publication No. 6-23088), a mucopolysaccharide and natto extract,
An external preparation for skin (JP-A-2000-34219), which has an excellent moisturizing effect and suppresses the sticky feeling peculiar to mucopolysaccharides, is disclosed.

[0009]

As described above, yeast or yeast extract and natto extract are useful for skin moisturizing effect and cosmetic effect. However, with these single blends, the expected action and effect are not fully exhibited, and they are not satisfactory. In addition, the synergistic effect of these and other components has not been sufficiently investigated at present, and there are few known examples of effective utilization. Therefore, a cosmetic having an excellent moisturizing effect cannot be obtained by simply blending it. Furthermore, skin moisturization is also the ultimate problem of cosmetics, and development of cosmetics having an excellent moisturizing effect has been earnestly desired.

[0010]

Means for Solving the Problems The present inventors have extensively and extensively studied various moisturizers in order to obtain cosmetics having a high moisturizing effect, and as a result, yeast and / or yeast extract and natto extract were obtained. It has been found that the skin moisturizing effect can be remarkably enhanced by the combined use and the addition of xanthan gum and / or pullulan together with the above components, and the present invention has been completed based on this finding.

That is, the present invention is a cosmetic composition containing yeast and / or yeast extract and natto extract as components, and further containing xanthan gum and / or pullulan together with the components, which activates the metabolism of the skin, Another object of the present invention is to provide a cosmetic having excellent effects on skin protection and moisture retention, such as imparting elasticity and flexibility, preventing dryness, and improving skin.

Specifically, yeast and / or yeast extract 0.001% to 20.0% and natto extract 0.01% to 2
Provided is a cosmetic composition containing 0.0% of xanthan gum and / or 0.001% to 10.0% of pullulan.

Furthermore, the present invention provides a cosmetic composition in which mucopolysaccharide is added to the above-mentioned cosmetic ingredients.

Further, by impregnating a nonwoven fabric with the above-mentioned cosmetics, it was found that a nonwoven fabric-impregnated cosmetic product which is free from dripping from the nonwoven fabric, has an excellent feeling of use, and has a high moisturizing effect can be obtained, and the present invention is completed. I arrived.

That is, according to the present invention, a cosmetic composition containing yeast and / or yeast extract and natto extract and further containing xanthan gum and / or pullulan has a water absorption of 7 to 10 times its own weight and a basis weight of 50 g / m ^{2 to} 100 g / m
Provided is a nonwoven fabric-impregnated cosmetic material obtained by impregnating the nonwoven fabric of No. ² above.

Further, the present invention provides a non-woven fabric-impregnated cosmetic containing a mucopolysaccharide. The mucopolysaccharide is incorporated into the nonwoven fabric by impregnating the nonwoven fabric with a yeast and / or yeast extract and a natto extract, and further mixed with xanthan gum and / or pullulan as a cosmetic.
