Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder pack cosmetic which is free of tension and irritation to the skin during use and is excellent in moisturizing the skin after use.

[0002]

2. Description of the Related Art Recently, the need for products such as powdered pack cosmetics has increased due to the beauty treatment salon boom. BACKGROUND ART Conventionally, powdery pack cosmetics characterized by containing water-soluble alginates are known, and the pack cosmetics contain a metal salt having a valence of 2 or more, such as calcium sulfate, which reacts with the water-soluble alginates. Then
The mainstream method is to mix it with an appropriate amount of water at the time of use to form a paste, apply it to the entire body, form a film, dry it for a certain period of time, and then peel it off.

However, the pack cosmetics having these constitutions have drawbacks such as tightness and irritation to the skin when used.

[0004] That is, an object of the present invention is to provide a powder pack cosmetic which has no tightness and irritation to the skin during use and is excellent in moisturizing skin after use.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies in view of such circumstances, and as a result, powdery pack cosmetics containing a dried seawater product and water-soluble alginates,
Furthermore, powdered pack cosmetics containing at least one substance selected from seaweed powder, seaweed extract, tea extract and caffeine in dried seawater and water-soluble alginates are applied to the skin during use. On the other hand, the present invention has been completed by finding an effect that is not taut or irritating and is excellent in moisturizing the skin after use.

The details of the configuration of the present invention will be described below.

The main constituents of salts dissolved in seawater are mainly fluorine, mainly 8 components of chlorine, sulfuric acid, bicarbonate and bromine anions and sodium, magnesium, calcium and potassium cations. It also contains boron, etc. The number of elements dissolved in seawater has been confirmed to be over 70.

The dried seawater used in the present invention may be freeze-dried as it is, using seawater as a raw material. However, in order to reduce salts that cause stickiness, it is desalted with a so-called reverse osmosis membrane and frozen. A dried seawater dried product is particularly preferable.

The desalted seawater dried product has less chlorine and sodium as compared with the freeze-dried seawater, as well as so-called trace elements such as magnesium, potassium, phosphorus and calcium. Richly included. Also, from the viewpoint of product stability, desalted products are preferable. Table 1 shows an example in which the components of the dried seawater dried seawater and desalted and dried seawater dried product were compared.

[0010]

[Table 1]

The blending amount of the dried seawater in the present invention is 0.1 to 70% based on the total amount of the cosmetics.
(Hereinafter referred to as “wt%”) is preferable, and particularly 0.5 to
50% is preferable. If it is less than 0.1%, the reaction with the water-soluble alginates is not sufficient, and if it is more than 70%, it is not suitable in terms of the stability and cost of the product.

As the water-soluble alginates in the present invention, sodium alginate, potassium alginate,
Examples thereof include ammonium salts.

The amount of the water-soluble alginate compounded is preferably 1 to 60%, and more preferably 3 to 30%, based on the total amount of the cosmetic. If it is less than 1%, the strength of the gel is weak and it cannot be peeled off neatly. On the other hand, if the amount is more than 60%, when water is added, the powder is solidified, that is, remains in the powder and cannot be sufficiently mixed, so that a uniform paste cannot be obtained. Also, it is not appropriate in terms of cost.

As the seaweed powder used in the present invention, brown algae rich in vitamins and minerals, red algae,
It is obtained from cyanobacteria and is a powder obtained by heat drying and freeze drying.

The seaweed extract used in the present invention is seaweed itself, or an extract extracted from powder with water, hot water, an aqueous solution containing an organic solvent, an organic solvent or the like, which is commonly known.

The tea extract used in the present invention includes green tea, semi-fermented tea, fermented tea, and post-fermented tea obtained from tea trees, which include vitamin C, catechin, flavonoids, and caffeine, and are commonly known. Water, hot water,
It is an extract obtained by extraction with an aqueous solution containing an organic solvent, an organic solvent, or the like.

As the usual method for extracting seaweed or tea extract, water-soluble or oil-soluble ones extracted with a solvent such as alcohol, glycerin, 1,3-butylene glycol, water or a mixture thereof are preferable. Is preferably freeze-dried and dried with hot air using a binder or the like.

The caffeine used in the present invention may be either a natural product or a synthetic product obtained by concentrating tea and coffee through ordinary extraction and purification and concentration.

The amount of the seaweed powder, seaweed extract, tea extract and caffeine used in the present invention is preferably 0.01 to 30% based on the total amount of the cosmetic.

If desired, the powdery pack cosmetic of the present invention may be used in appropriate combination with other components usually used in pack cosmetics. For example, crystalline cellulose, magnesium carbonate, dicalcium phosphate, tricalcium phosphate, calcium monohydrogen phosphate, calcium chloride, magnesium phosphate, silica, zeolite, sodium metaphosphate, aluminum hydroxide, which are generally used as excipients. , Magnesium hydroxide, calcium pyrophosphate, sodium pyrophosphate, sodium citrate, calcium citrate, citric acid, sodium hexametaphosphate, sodium carbonate, calcium lactate,
