Description

Composition for hair protection including graphene {Composition For Hair Protection Comprising Graphene}

The present invention relates to a hair protection composition containing graphene, and more particularly, to a hair protection composition comprising purified water, an alkanediol having 5 to 10 carbon atoms, a hair protection agent, and graphene.

In modern society, hair is more often damaged by physical and chemical factors such as perms and dyeing, or environmental factors. In particular, in the case of consumers who use an iron or hair dryer every day, hair damage occurs in many cases due to high-temperature hot air balloons. In particular, wet hair is swollen by moisture, and when pressure is applied to a high temperature in this state, moisture evaporates and causes cracks in the epidermis, cortex, and medulla, thereby damaging the hair.

In order to prevent such hair damage, various hair products are being developed, for example, a composition using a natural material rather than a synthetic material, a composition using silk protein, a composition using a protein hydrolysis material such as keratin and collagen, etc. Although compositions for hair protection have been developed, there is a limit to protecting hair only with the existing hair products for hair protection.

Under this background, the present inventors have developed a composition capable of maintaining moisture inside the hair and preventing hair damage even by strong heat or pressure.

The composition of the present invention includes purified water, an alkanediol having 5 to 10 carbon atoms, a hair protectant, and graphene. Hereinafter, each active ingredient will be looked at in detail.

First, the hair protectant acts as an insecticide of the hair to make the hair shiny and protect it. The hair protectant of the present invention may include any one or more of a wheat protein hydrolyzate, a collagen hydrolyzate, and a keratin hydrolyzate, and preferably include all of a wheat protein hydrolyzate, a collagen hydrolyzate and a keratin hydrolyzate.

The wheat protein hydrolyzate refers to hydrolyzate hydrolyzate of wheat protein, a protein source, by enzymes, acids or bases, etc. It serves to prevent damage.

The wheat protein hydrolyzate may be prepared by various methods, but preferably, the wheat protein is inoculated with a microorganism and fermented; Separating the wheat protein fermented product by centrifugation into a precipitate and a supernatant; extracting the precipitate with hot water to obtain an extract; and mixing the supernatant and the extract. Let's look at each step in detail below.

First, wheat protein is inoculated with microorganisms and fermented. In this case, the microorganism may be at least one selected from the group consisting of yeast, lactic acid bacteria, bacteria, and mold.

The yeast is an example Saccharomyces cerevisiae (Saccharomyces cerevisiae), Saccharomyces ellipsoideus (S ellipsoideus), Saccharomyces coreanus (S coreanus), Saccharomyces Carlsbergensis (Scarlsbergensis), Saccharomyces pastorianus, Saccharomyces lactis, S rouxii, Schizosaccharomyces pombe, Zigosaccharomyces major (Zygosaccharomyces major), Hansenula anomala, Brettanomyces bruxellensis, Brettanomyces custersianus, Deckeraanomala, Streptomyces It may be Streptomyces olivochromogenes, or S griseus.

In addition, in one example, the lactic acid bacteria is Bifidobacterium bifidum (B bifidum), Bifidobacterium breve (B breve), Bifidobacterium longum (B longum), Bifidobacterium animalis (B animalis), Bifidobacterium lactis (B lactis), Lactobacillus acidophilus (Lacidophilus), Lactobacillus casei (L casei), Lactobacillus gasseri (L gasseri), Lactobacillus delbrueckii species (L delbrueckii spp), Lactobacillus bulgaricus (L bulgaricus), Lactobacillus helveticus (L helveticus), Lactobacillus fermentum (L fermentum), Lactobacillus paracasei (L paracasei), Lactobacillus plantarum (Lplantarum), Lactobacillus reuteri L reuteri), Lactobacillus rhamnosus (L rhamnosus), Lactobacillus salivarius (L salivarius), Lactococcus lactis (L lactis), Pediococcus cerevisiae (P cerevisiae), Pediococcus acidi lactisi ( P acidilactici), Streptococcus lactis (S lactis), Streptococcus thermophiles (Sthermophiles), Streptococcus cremoris (S cremoris), or leukonostok mesenteroides (L mesenteroides).

In addition, the mold used for the fermentation is not limited thereto, but may include mushrooms, for example, shiitake, oyster mushroom, enoki mushroom, matsutake mushroom, matsutake mushroom, wood ear mushroom, roe deer mushroom, reishi mushroom, or It may be a situation mushroom, but is not limited thereto.

The inoculation amount of the microorganism, the culture temperature, the culture humidity, and the culture time can be appropriately selected by those skilled in the art in consideration of the type of microorganism used for fermentation, and the like. As an example, the fermentation of the present application may be carried out at a temperature of 20°C to 40°C for 12 hours to 60 hours.

The fermented wheat protein can be centrifuged to separate the supernatant from the precipitate. At this time, the centrifugation may be performed at 6,000 rpm to 10,000 rpm for 10 minutes to 60 minutes.

The precipitate may be again subjected to a hot water extraction process to obtain a hot water extract. At this time, it is preferable to use alkaline ionized water as a solvent for hot water extraction at 70 to 80° C. for 1 to 3 hours. Alkaline ionized water has a smaller molecular group than water, so it has good penetrating power, and has high thermal conductivity and strong dissolving power. It is preferable that the alkaline ionized water contains 1 to 30% by weight of glycerin, and the glycerin enables good and safe dissolution of the active ingredient, and a moisturizing effect can be obtained.

The supernatant and the extract thus obtained may be finally mixed and used as a wheat protein hydrolyzate, and preferably, the supernatant and the extract may be mixed in a weight ratio of 2 to 5:1.

On the other hand, the collagen hydrolyzate and keratin hydrolyzate refer to those obtained by hydrolyzing collagen and keratin by an enzyme, acid, or base, and various commercially available hydrolysates may be used.

The wheat protein hydrolyzate, collagen hydrolyzate, and keratin hydrolyzate may be mixed by various mixing ratios, but preferably in a weight ratio of 1-2:1-2:1-2. In addition, it is preferable that the content of the hair protectant is 0.01 to 30% by weight of the total composition, and when it is less than this, it is difficult to exhibit a functional effect, and in many cases, the increase in the functional effect is insufficient.

The graphene is adsorbed to the hair surface to protect the hair, and various commercially available graphene may be used, but preferably graphene encapsulated with cyclodextrin may be used. Cyclodextrins are cyclic oligosaccharides, generally depending on the number of glucose units: α-cyclodextrin (α-CD, 6 glucose), β-cyclodextrin (β-CD, 7 glucose), γ-cyclodextrin (γ- CD, 8 glucose). They have high crystallinity and have a toric structure that does not absorb moisture. The cyclodextrin prevents the graphene from aggregating with each other and allows the graphene to be well dispersed in the composition, thereby allowing the graphene to more effectively protect the hair.

The graphene encapsulated with the cyclodextrin may be prepared by various commercially available methods, for example, mixing graphene, cyclodextrin, and NaBH4; sonicating the mixture obtained above; and mixing the ultrasonicated product with distilled water and filtering.

The content of the graphene is preferably 0.000001 to 10% by weight of the total composition, and when it is less than this, it is difficult to exhibit a functional effect, and in many cases, the increase in the functional effect is insufficient.

The alkanediol having 5 to 10 carbon atoms acts as a preservative, and 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, caprylyl glycol, ethylhexylglycerin, decylene One selected from the group consisting of glycol and glyceryl caprylate or a mixture thereof may be used. The content of the alkanediol is preferably 0.1 to 5% by weight of the total composition, and finally, purified water includes the remaining amount as a solvent.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through specific manufacturing examples and examples. However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

The combing value is related to the softness and the degree of tangling of the hair, the lower the better. As can be seen from the above table, the Example had the best combing value compared to the Comparative Examples.

[Experimental Example 2] Heat protection experiment during magic operation

Visual and sensory evaluation

The hair sample was subjected to a magic procedure, but the hair was immersed in Examples and Comparative Examples 1 to 3 before pressing at a high temperature, and the results of visual and sensory evaluation are shown in FIG. 2 and Table 2 below. The higher the linearity and the lower the degree of damage, the higher the score.

Rating (1-5 points) Visual evaluation/sensory evaluation linearity degree of damage Example 4.5 5.0 Visual: high linearity, calm and no visible damage
Tactile: Smooth and moist throughout, no damage to the tips
Sagging: Select 20 hair strands at random and hang them on a jig, and 4 strands that will sag when pulled. Comparative Example 1 4.0 4.5 Visual: High linearity, but some parts do not straighten, damage to the tip is visible
Tactile: Smooth and moist throughout, slight damage at the tips
Sagging: Select 20 hair strands at random and hang them on a jig, 5 strands that sag when pulled Comparative Example 2 5.0 4.0 Visual: low straightness, obvious damage throughout the hair, severe static electricity and tangles
Tactile: Overall dry and damaged.
Sagging: 20 strands are randomly selected and 15 strands that hang when pulled on a jig. Comparative Example 3 1.0 1.5 Macroscopic: damage to the middle and tip of the hair
Tactile: The hair is very dry and the overall damage is felt, the ends are severely damaged.

The state after application of the first agent during the magic procedure is the state in which the hair swells due to the reducing agent and the cystine bond is broken. Therefore, the hair insecticide may escape and the result of the procedure may be low.

As can be seen from the above results, it was found that the hair protectant capable of filling the insecticidal material improved the linearity and the graphene prevented thermal damage, so that the Example exhibited high linearity and damage.

Combing

The hair sample was subjected to a magic treatment, but before the hair was pressed at a high temperature, the hair was immersed in Examples and Comparative Examples 1 to 3, followed by a combing experiment, and the results are shown in Table 3 below.

The combing value is related to the softness and the degree of tangling of the hair, the lower the better. As can be seen from the above table, the Example had the best combing value compared to the Comparative Examples.

As can be seen from the above experimental examples, it was found that the hair treated with the examples of the present invention had excellent heat protection ability, thereby minimizing damage to the epidermis and preventing the combing value from increasing.

Although the present invention has been described in relation to the preferred embodiment as mentioned above, the technical spirit of the invention is not limited or limited thereto, and it is of course that it can be variously practiced with modifications by those skilled in the art.
