The compounding amount of the above-mentioned component (b), dimethylsilanol hyaluronic acid ester methylsilanol and / or pyrrolidone carboxylic ester, is contained in the total amount of the cosmetic.
0.0001 to 10% by mass is preferred.

In the present invention, the object of the present invention can be remarkably achieved by further blending an extract from beech tree buds in addition to the above components (a) and (b). Extracts from beech tree buds include beech (Fagus crenata Bl)
ume), European beech (Fagus silvat)
ica L. ), Orient beech (Fagus ori)
entalis Lipsky), and preferably the sprouts of beech plants, such as water, ethanol, 1,3-
Extracted with a single solvent or a mixed solvent of solvents such as butylene glycol. As an extract of beech tree buds, for example, European beech (Fagus silatic)
a L) germ extract, trade name GATULI
NERC (launched by Ikeda Bussan).

In the present invention, if an extract from seaweed is further added in addition to the above components (a) and (b), the object of the present invention can be remarkably achieved. Examples of extracts from seaweed include genus Hibamata (Fucus) belonging to brown algae (Phaeophyceae), genus Laminaria, and genus Chondrus belonging to red algae (Chondrus).

-An extract obtained by extraction with butylene glycol, ethylene glycol monobutyl ether, ethanol, glycerin, or a mixture thereof. In the present invention,
Beech tree bud extract and / or extract from seaweed,
0.000 in terms of dry residue of extract in total amount of cosmetics
It is preferable to mix 5 to 4% by mass.

The cosmetics of the present invention include skin lotions, skin creams, make-ups, sunscreens, body lotions, packs, makeup bases, hair tonics, bath additives and the like. It is particularly suitable for a pack material, and is preferably applied to a peel-off type or sticking type sheet-like pack material because it can remove skin stains and reduce skin irritation when the pack material is peeled off.

The pack material contains a water-soluble polymer compound. Examples of the water-soluble polymer include polyacrylic acid or a salt thereof (sodium salt, potassium salt, amine salt, ammonium salt, etc.) and polymethacrylic acid. Or a salt thereof (sodium salt, potassium, amine salt, ammonium salt, etc.), polyacrylamide, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethyl cellulose, carrageenan, xanthan gum, pullulan, agar, gelatin, sodium alginate, gum arabic, chitosan salt, etc. These are water-soluble synthetic high molecular compounds or natural high molecular compounds, or copolymers of the components of the above water-soluble high molecular compounds, all of which bring the pack composition into a gel state. In the present invention, one or more of these water-soluble polymer compounds,
It is preferable to mix 1 to 98% by mass in the pack material.

The use of a pack applied to a sheet base is excellent in convenience. For sheet base, nylon, polyethylene, polypropylene, polyester,
Woven, non-woven, or nylon, polyethylene, polypropylene made of synthetic fibers such as polyurethane, natural fibers such as silk, cotton, hemp, rayon, and collagen, and recycled fibers.
Examples include thin sheets of synthetic resins such as polyester and polyurethane, water-resistant paper, silk fibroin sheets, collagen sheets, chitosan sheets, and aloe sheets. These sheet substrates may be compounded with those of other materials,
Further, it may have fine holes for moisture permeability, and may be one subjected to a hydrophilic treatment, a hydrophobic treatment, or a raising treatment. The thickness of the sheet substrate is preferably about 0.1 to 5 mm from the viewpoint of adhesion to the skin and strength. In the present invention, it is preferable that the sheet base is provided with a cutting line, and if the cutting line can be cut along the cutting line, a dot-like, linear perforation, or a linear shape is formed on the sheet base by a pressing blade. May be provided. The cutting line may be formed on the sheet base before the pack composition is supported on the sheet base, but it is preferable to form the cutting line on the sheet base and the pack composition supporting the pack composition at the same time. . The shape of the sheet substrate is rectangular, trapezoidal, circular, elliptical, and the like, and when affixed to a small area of a local part of the skin,
By cutting along the cutting line, the sheet base material can be divided into small substantially triangular, rectangular, trapezoidal, and the like. That is, it may be cut and divided and adhered to a small part such as an eye or a mouth, or may be directly adhered to a large part such as a neck or a back without being divided and divided.

[0016] In addition to the above components, the cosmetics and packs of the present invention may further include a solvent such as alcohol; an adhesion promoter comprising a water-insoluble polymer; a blood circulation promoter; glycerin, polyglycerin, 1,3-butylene glycol; Moisturizers such as propylene glycol and sugars; whitening agents; sebum secretagogues; oils; fragrances; salts; chelating agents;
Dyes and the like can be appropriately compounded within a range that does not impair the effects of the present invention.

The cosmetics and packs according to the present invention are preferably applied to the face of the person in their thirties to forties who are concerned about aging, such as the neck, eyes and mouth.

[0018]

The present invention will be described below in more detail with reference to Examples and Comparative Examples. The sensory evaluation method used in the present invention is as follows.

Sensory Evaluation Method Ten female panelists in their thirties to forties affix the sheet-shaped pack to one eye every day before going to bed and use it for one week so that it can be peeled off after getting up. Compared to the cheeks and eyes around those who did not, the number of respondents who answered that "skin was moistened", "skin was firm", "stain was removed", "no pain when peeling" The evaluation after use was performed.

Examples 1 and 2 and Comparative Examples 1 to 3 (Sheet-shaped pack material) Gelatin of the components shown in Table 1 below was dissolved in 10 g of purified water, and polyvinyl alcohol was dissolved in 10 g of purified water. The mixture was stirred and mixed under heating, and then a mixture of sodium polyacrylate and glycerin, and the remaining components were added and mixed by stirring to obtain a gel-like pack composition.
The pack composition prepared as described above was spread on a sheet substrate made of a polyester urethane sheet having open cells, and a release paper was attached to an exposed surface of the pack composition to obtain a sheet-like pack material. . In addition, dimethylsilanol hyaluronic acid ester is D.M.
S. H. C is methylsilanolpyrrolidone carboxylate copper salt, which is available from EXSYMOL's SIHYDR.
ATE C was used as an extract from beech tree buds, and GATULINE RC from Ikeda Bussan was used. As a seaweed extract, a lysate (brown algae) extract BG from Maruzen Pharmaceutical was used.
