DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a hair protecting effect, an antistatic effect, a moisture retaining function, and the like, thereby eliminating the feeling of the hair becoming stiff and giving the hair suppleness and strength.
The present invention relates to a novel hair cosmetic having an excellent effect of suppressing damage to hair.

[0002]

2. Description of the Related Art As is well known, the component of hair is composed of a protein called keratin. This protein called keratin is not only hair but also nail and skin stratum corneum, but hair and nails are called hard keratin and the skin stratum corneum is soft keratin, and the hard keratin of this hair component is very tough and usually Unlike other proteins, they are hardly spoiled and resistant to chemicals. However, hair is damaged or degraded by various external factors. If the cause is raised, first of all, even in a natural state, the hair is exposed to environmental factors (sunlight: ultraviolet rays, infrared rays), Chemical factors (heat, friction, drying, etc. of brushing, dryer, etc.) and chemical factors (acids, alkalis, oxidizing agents, reducing agents, etc., such as hair perms, hair dyes, hair bleaching, etc.) In addition, the damage to the hair is increased.

[0003] In addition, due to these external factors, the water content (normally 11 to 13%) of hair in a natural state of a healthy person disappears, and the hair becomes dry and loses its texture, texture and luster. . Further, it is said that when the surface of the hair is damaged, split ends and cut hairs are generated, and the original strength of the hair is reduced. In addition, changes in the composition of amino acids, which are constituents of hair, generation of abnormal amino acids, and elution of amino acids generated by decomposition of keratin due to external factors do not cause change or damage to hair. Thus, once damaged hair, unlike skin, has no repairing ability and becomes permanently damaged hair.

[0004] Therefore, as described above, because the hair does not have a self-repair and regeneration ability of the damage, the important thing is, in the case of a damaged hair, is in or to protect how not to proceed with damage from the outside, In the case of normal hair, it is important how to prevent external factors so as not to cause damaged hair. That is, by protecting against these causes, both normal hair and damaged hair will eventually give the hair smoothness, strength, flexibility, luster and the like.

[0005] Conventionally, as a hair cosmetic composition, to compensate for these points, silicone oil, oil such as paraffin oil, humectants such as glycerin, also various surfactants,
Extracts and extracts of animals and plants from natural products, proteins, amino acids, polysaccharides, natural polymers and the like are blended and used.

[0006]

However, the conventional hair cosmetics have some effects in terms of imparting smoothness and moist feeling to hair.
In all cases, the effects were not long-lasting, the feel of the hair was inferior in terms of smoothness, flexibility, gloss, etc., and the stability was insufficient.

[0007]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that trehalose and amino acids are used in hair cosmetics.
Or one or more of amino acids consisting of these salts
The present inventors have found that the above-mentioned problems can be satisfied by containing , and completed the present invention.

[0008] That is, the present invention is trehalose, small
At least one amino acid or amino acid salt containing hair
It provides cosmetics .

[0009] Trehalose (Trehalose) used in the present invention.
ose) is a type of disaccharide in which two molecules of D-glucose are bonded to each other via a reducing group, is a non-reducing sugar, and has the following structure.

[0011] The trehalose of the present invention and the amino acid or this
The amino acid content of these salts can be applied to and rubbed on the hair in various forms such as emulsion, wax, solid, spray, solution, powder, and gel. or,
It is blended with a known hair cosmetic base or the like by a conventional method, and is used for hair cream, hair rinse, hair tonic, hair treatment, hair conditioning, set lotion, hair oil, hair spray, shampoo, hair dye,
It can also be used as a drug solution for other drugs, quasi-drugs, and cosmetics (including various preparations used for humans and other animals and plants).

Furthermore, vitamins (vitamin A, vitamin B, vitamin C, vitamin E, etc.), astringents (allantoin, tannic acid), various surfactants (cationic,
Anionic, amphoteric, nonionic surfactants), coloring agents (gardenia yellow, β-carotene, paprika, shikonin, chlorophyll, etc.), fragrances, plant and animal extracts, function enhancers, bactericides, preservatives, anti- It is stable against oxidizing agents, ultraviolet absorbers, chelating agents, thickeners, humectants, solvents, other various additives, pharmaceutical and cosmetic bases, and is compounded with these commonly used drugs, etc. An effect can be obtained by using them in combination. It can also be used in the food field.

The trehalose and amino acids of the present invention or amino acids composed of salts thereof may be commercially available products, and may be extracts from animals and plants, microbial culture products, or those obtained by synthetic methods. Trehalose is usually present in a crystalline state as dihydrate crystals, but trehalose used in the present invention may be a dihydrate or an anhydrate.
Of course, it may be solid, solution, or gel. As the amino acids, valine, leucine, isoleucine, threonine, methionine, phenylalanine, tryptophan,
Lysine, glycine, alanine, asparagine, glutamine, serine, cysteine, cystine, tyrosine, proline, hydroxyproline, aspartic acid, glutamic acid, hydroxylysine, arginine, ornithine, histidine, etc., and amino acid salts (sulfate, phosphate, Nitrates, citrates, etc.) can also be used.

Furthermore, as the amount thereof, respectively 0.1% by weight or more preferably, trehalose (trehalose dry solid basis (hereinafter, unless otherwise specified, percentages are meant weight%.): Hereinafter, trehalose The concentration is preferably 3.0% or more in the case of all concentrations expressed in terms of anhydride), and 5.0% or more in the case of amino acids consisting of amino acids or salts thereof.

The characteristic properties of the hair cosmetic of the present invention are described below.

Table 1 shows the color stability of the hair cosmetic composition of the present invention.
As shown in FIG.

[0017] The tensile strength of the hair, as shown in Table 2,
Good results are obtained, which increase the strength of the hair itself and have a protective effect on the hair.

[0018] In addition, the antistatic effect, through the Table 3
On the other hand, trehalose and amino acids give very good results as compared with the case where other saccharides are used.

[0019] Also, as shown in Table 4, the persistence of moisture retention of hair, smoothness, moist feel, improved gloss, may be comb, also for the stability of the emulsion, the product of the present invention to comparative In comparison, good results are obtained overall.

Hereinafter , the present invention will be described in detail with reference to Examples, but it goes without saying that the present invention is not limited to these.

[0021]

【Example】

[0022] Create a Example 1 (color stability test) Test method and evaluation methods each specimen and the comparative products were examined macroscopically stability over time but were stored in 50 ° C. constant temperature bath.

% Solution , comparative product: Amino acid mixture 20% solution, lactose 5%
Solution, glucose 5% solution, lactose 5% solution + amino acid mixture 20% solution, glucose 5% solution + amino acid mixture 20
Table 1 shows the results.

[0023] As the composition ratio of the amino acid mixture (wt%), arginine hydrochloride, histidine hydrochloride,
Aspartic acid: glutamic acid: isoleucine: threonine: valine: alanine = 15: 15: 15: 15: 1
Using 0: 10: 10: 10, the composition of the amino acid mixture of Examples 2-13 below was the same.

[0024]

[Table 1]

[0025] Test Results The results as shown in Table 1, amino trehalose solution of the present invention
It was confirmed that the one to which the acid mixture was added did not show coloring even for a long period of time. From these results, it can be confirmed that since trehalose is a non-reducing sugar, it does not cause a Maillard reaction and is stable. On the other hand, it was confirmed that the comparative product (amino acid mixture + grape or lactose: reducing sugar) was colored.
