Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cosmetic quality improving agent that is incorporated into cosmetics for skin or hair, and to cosmetics containing the additive.

[Prior art]

Conventionally, cosmetics such as hair tonics, creams, emulsions, shampoos, soaps, and conditioners contain hot water extracts of chlorella algae as they are, or hot water extracts of chlorella algae from which proteins that cause putrefaction have been removed. is known, and a pack agent in which a ground material obtained by crushing dried chlorella algae is blended with a pack base material is also known.

[Problem to be solved by the invention]

The present inventor has proposed that the hot water extract of Chlorella algae as it is, or the hot water extract of Chlorella algae from which water-soluble proteins that cause putrefaction have been removed, be used in cosmetics that do not simply contain Chlorella algae. It is not a cosmetic that uses proteins from Chlorella algae by grinding it, but it contains more amino acids by decomposing the water-soluble proteins in the hot water extract of Chlorella algae into amino acids that are effective for the skin. The present invention was achieved as a result of research on the use of this as a hot water extract of chlorella in cosmetics and cosmetic formulations.

[Means to solve the problem]

The present invention is a cosmetic formulation characterized by containing an enzyme-treated chlorella hot water extract obtained by decomposing a chlorella algae hot water extract with a proteolytic enzyme.

Further, it is a skin cosmetic characterized by containing 1 to 40 parts by weight of a cosmetic compounding agent,
In particular, 3 to 15 parts for facial cleansers and 3 to 10 parts for lotions.
The skin cosmetic contains 1 to 40 parts of emulsifying cosmetics.

Also, a peel-off pack agent containing 1 to 20 parts by weight of a cosmetic compounding agent;
Hair cosmetics such as hair tonics and shampoos.

[Detailed description of the invention]

In the present invention, the hot water extract of chlorella algae is treated with a proteolytic enzyme in the formulation for cosmetics. In order to increase the amount of water-soluble proteins, water-soluble proteins are removed, but in general removal processing, the content of amino acids contained in the extract along with water-soluble proteins, polysaccharides, etc. is reduced. This is to prevent this.

Proteolytic enzyme (protease) in the present invention
In the case of processing, without loss of amino acids,
Because it decomposes water-soluble proteins, the extract contains
Chlorella is suitable for cosmetics because it contains a larger amount of amino acids, which is attracting attention as a natural moisturizing factor, along with polysaccharides and peptides, and has a good shelf life. A hot water extract of algal bodies was obtained.

As the proteolytic enzyme, general food processing enzymes such as trypsin, chymotrypsin, pepsin, etc. are used, and the enzyme treatment is naturally performed by adjusting the optimum pH of the proteolytic enzyme to be used. The body heat water extract is prepared and then processed.

In the present invention, the cosmetic formulation consisting of a hydrothermal extract of Chlorella algae treated with a proteolytic enzyme also refers to a formulation to which fresh water or cosmetic formulation substances, such as other general moisturizing agents, etc. are added. . In addition, cosmetics containing appropriate amounts of the above cosmetic ingredients are:
All cosmetics, i.e. facial cleansing cream, lotion, emulsion,
Nutrient creams, cold creams and other skin cosmetics, hair tonics, cream shampoos,
means cream rinses and other hair cosmetics;
The blending ratio of the above cosmetic ingredients is 1 to 40 parts by weight in skin cosmetics, and especially 3 to 15 parts by weight in facial cleansers.
Parts by weight, lotion 3-10 parts by weight, emulsified cosmetics 1-40 parts by weight
