Description

Hypoallergenic cosmetic composition for adolescents}

The present invention relates to a hypoallergenic cosmetic composition for adolescents, and more specifically, to a cosmetic composition suitable for adolescents including natural extracts and herbal water and a method for preparing the same.

There are two types of sweat glands: apocrine glands and eccrine glands. Apocrine glands cause body odor because part of the cell is broken down and mixed with sweat. Sweat from the apocrine gland contains a relatively large amount of organic substances such as lipids, proteins, and amino acids. The secreted fresh sweat has no odor, but on the way to the stratum corneum of the skin, it is decomposed by the normal bacterial layer of the skin and turns into an unpleasant odor.

As such, decomposition by microorganisms generates odorous substances. Sweat secretion products include lower fatty acids such as caproic acid, caprylic acid, isovaleric acid, and butric acid, and mercaptan, amine, ammonia, indole, hydrogen sulfide, and phosphine. hine) and steroids were identified. In particular, among lower fatty acids, isovaleric acid, 5-androst-16-en-3-alpha-ol (5-androst-16-en-3-ol) and 5-alpha-androst-16-en-3-alpha-one (5-androst-16-en-3-one) among steroids are known to be the main factors. In addition, in the case of foot odor, it is known that isovaleric acid produced by microorganisms decomposing eccrine sweat is the main cause. Sweat from the eccrine glands is also decomposed by the normal bacterial layer of the skin to generate an odor, but since the amount of residual organic matter is small, the odor is weak and mild, essentially different from the unpleasant odor caused by apocrine sweat. However, it plays an indirect role against the occurrence of body odor, such as promoting the growth of the normal bacterial layer of the skin, which is the main component of eccrine sweat, and increasing the emission of unpleasant body odor when moisture evaporates.

In order to eliminate such body odor, various and continuous studies on the main components of deodorants have been conducted.

A representative research result is the application of chemical components other than plant extracts as deodorants. Major prior patents related to this include Korean Patent No. 10-0566661, a cosmetic composition containing ethanol, polyhydric alcohol, salicylic acid, triclosan, allantoin, licorice acid or its di-alkali metal salt, dl-campa, apple mint leaf extract, green tea extract, and aloe extract as main components, and containing water and fragrance essence, and Korean Patent No. 10-1470389, triclosan and bamboo salt And a cosmetic composition containing tocopherol acetate, a cosmetic composition containing the yulpi extract of Korean Patent Registration No. 10-1554537 as an active ingredient, and a cosmetic composition containing a colored barley extract of Korean Patent Publication No. 10-2016-0081213.

However, the above existing inventions were not sufficiently considered for the sensitive and weak skin of adolescence, and there was a problem that they were not suitable for use in adolescence.

On the other hand, hair loss is an extremely common condition and it is estimated that about 20-25% of the population suffers from some type of hair loss disorder. Although hair loss is more common in adult males, hair loss disorders also affect women and children. Although most hair loss disorders do not in themselves impair an individual's health, many patients report related psychological problems including anxiety or depression.

However, despite the prevalence of hair loss disease, there is no effective treatment. Surgical treatment is available for restoration of hair, especially for the scalp. However, these techniques have inherent risks associated with painful, costly, and invasive surgery. In addition, hair restoration surgery typically requires dense hair growth of at least some areas to be available to the transplant recipient for implantation or relocation to another part of the recipient's body. In addition, surgical treatment is difficult to apply to patients with alopecia areata, in which spontaneous regrowth of hair followed by re-falling is common.

Currently, various studies for hair loss prevention and hair growth are being actively conducted, and in particular, studies on hair loss prevention and hair growth using oriental herbal medicines have been actively conducted.

However, even though such active research is being conducted, development of hair loss shampoos and the like for teenagers has hardly been made.

Accordingly, the present inventors attempted to invent a composition that simultaneously exhibits effects of suppressing body odor and preventing hair loss, while not burdening the skin even when used in adolescence, by including extracts derived from various natural products.

One aspect of the present invention provides a composition for suppressing body odor and preventing hair loss in adolescents, comprising at least one selected from the group consisting of zinnia mushroom extract, raspberry extract, centella asiatica extract, tea tree extract, apple mint leaf extract, green tea extract, thyme extract, eucalyptus leaf extract, nettle extract, alba freesia extract, peppermint leaf extract, grapefruit extract, rosemary leaf water, iris root stem water and ginkgo leaf water.

It reaches 7m in height, and the bark is dark brown. The leaf is a compound leaf with 7-13 egg-shaped small leaves arranged in a feather shape. There are serrations on the edge of the leaf, and there are wings between the small leaves and the small leaves. Flowers are yellowish white, and bloom in clusters in panicle in August-September on trees of different sexes. The round fruits ripen in yellowish red in October and are covered with white sticky powder, which tastes sour and salty. The name red tree comes from the exceptionally red leaves in autumn. The worm's nest formed on this tree is called gallbladder and is used as a medicine for the treatment of dysentery or diarrhea, and is also used as a raw material for ink and dye. The white powder of the fruit is also used as a bittern in tofu production.

In the present invention, the " Centella asiatica " is a perennial plant that is common in the mountains and fields of the southern islands of the Korean Peninsula. The main stem extends to the side, and there are 2 degenerated scale-like leaves near the root node. Leaves grow densely at nodes, elongated, 2-5cm in diameter, glossy surface, with dull sawtooth on the edge, petiole 4-20cm long. Flowers are reddish-purple, 3-4 flowers hang in the axils in an umbel, and are shaped like heads. The style is two-pronged, and the fruit is the oblong shape of the branch.

In the present invention, the "tea tree ( Melaleuca alternifolia )" is an evergreen tree belonging to the Myrtaceae family. This swamp plant is native to Australia and is native to New South Wales. It grows up to about 6m in height, and its vitality is strong enough to grow well even if the stem is cut off. Tea tree is often distilled and used in the form of oil, and it has been proven to have antibacterial and antifungal properties. During World War II, it was issued to soldiers in the tropics as a remedy for skin wounds and was also used to treat wounds. Because of its antibacterial and antifungal properties, it is used in various forms of medicines or cosmetics, such as wound disinfectants, acne sedatives, athlete's foot treatments, and respiratory disease treatments.

The "extract" refers to a solvent in which the active ingredient contained in the extraction raw material is transferred by contacting the solvent and the extraction raw material under specific conditions, and if the substance contained in the raw material is separated from a natural product, it may include all of them regardless of the type of extraction method or ingredient. For example, those obtained by extracting solvent-soluble components from natural products using water or organic solvents, and those obtained by extracting only specific components such as specific components of natural products, such as oil, may be included.

In addition, extracts derived from the natural products listed above, diluted or concentrated solutions of the extracts, dried products obtained by drying the extracts, preparations or purified products of the extracts, or mixtures thereof, etc. Furthermore, the extract may be extracted from natural, hybrid or mutant plants, and may also be extracted from plant tissue culture.

In the present invention, the "fermentation" means a process in which microorganisms decompose organic matter using enzymes. It is known that the effect of raw materials subjected to fermentation by the microorganisms is increased by at least 2 times to a maximum of several tens of times compared to before fermentation. Metabolites that have undergone fermentation contain a large amount of amino acids, organic acids, and antioxidants that are beneficial to the skin, so they promote skin metabolism and make the skin texture elastic and smooth. In addition, through the fermentation process, the particles become smaller and toxins such as heavy metals are decomposed, so the absorption rate increases and skin trouble or allergic side effects can be alleviated.

The “fermented extract” may be prepared by diluting the extract in a solvent, specifically, purified water to a certain concentration, inoculating a microorganism for fermentation, and fermenting the extract.

In the mixed fermented extract of various natural substances listed above, the effects of the composition of the present invention, such as blood circulation improvement, scalp temperature drop, dermal papilla cell growth promotion, and hair thickness strengthening, can be increased, and skin penetration as well as safety in the body can be remarkably improved.

As shown in Table 1, both Examples 1 and 2 exhibited an excellent scalp temperature lowering effect in skin temperature change, and it was confirmed that the temperature was relatively lower over time, and in particular, Example 2 was the most effective. In particular, in the case of Comparative Example 1 and the control group, the scalp temperature decreased only slightly but did not significantly decrease, and it was confirmed that the scalp temperature was still higher than that of Example 2 even after time had elapsed. From the above results, in the case of Examples 1 and 2, the scalp temperature It was confirmed that there is a substantial effect of preventing hair loss by rapidly lowering the temperature and continuously maintaining a low temperature.

Experimental Example 2. Confirmation of dermal papilla cell growth promotion effect through MTT-assay

Since dermal papilla cells exist in the dermal cell layer and play an important role in hair growth, it was confirmed whether the composition of the present invention has an effect of promoting the growth of dermal papilla cells.

For cell culture, a modified medium containing DMEM (Dulbecco's Modified Eagle Medium) medium, fetal bovine serum (FBS), and penicillin-streptomycin was used, and the cells were cultured at 37°C and 5% CO ₂ conditions. The cultured dermal papilla cells were exchanged for medium twice a week, washed with PBS every 6 to 7 days, and then centrifuged to separate the adhered cells with 0.05% trypsin-0.02% EDTA, and then subcultured and used in experiments.

Dermal papilla cells were dispensed by 200 μL so as to be 1x10 cells/well in a 96-well plate and cultured at 37° C., 5% CO ₂ conditions for 18 hours to allow the cells to adhere. After 18 hours, the medium was removed, and 200 μL of the sample was added to the wells to which the cells were attached and cultured for 24 hours. After removing the medium from the cultured cells, 100 μL of a 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazoliumbromide (MTT) solution prepared at a concentration of 500 μg/mL in PBS was added and further incubated for 4 hours under the same culture conditions. At this time, the formazan crystals produced were dissolved in DMSO and absorbance was measured at 540 nm with an ELISA reader, and the measured values within the OD range of 0.00 to 3.50 were used for the experimental results.

Experiments were conducted at a concentration of 0.5% each of the compositions of Examples 1 and 2 and Comparative Example 1 of the present invention, and cell viability is shown in Table 2 below. As a control group, distilled water was used.

On the other hand, Comparative Example 1, which is a composition excluding the zinnia mushroom extract, Rhus extract and herbal water, had a significantly lower cell viability, and it was confirmed that the control group did not show any effect.

Experimental Example 3. Confirmation of body odor suppression effect of Examples and Comparative Examples

After the shampoos prepared in Examples 1 and 2 and Comparative Examples 1 and 2 were directly divided into 4 groups of 5 people, 20 men and women between the ages of 12 and 18 in adolescence, an experiment was conducted to measure the antibacterial and deodorant effects. Specifically, the subjects were 20 adolescents who were worried that their scalp was often oily and smelly, and except for this shampoo, only unscented body washes were used, and products that affect the experiment, such as deodorants and perfumes, were not used. The smell of the crown of the head was measured at a certain time before the test and used as a reference point. The evaluation period was 2 weeks, and in the deodorization effect test, three well-trained sensory evaluation agents observed the sniff test by smelling the crown of the head directly.

As a result, after 2 weeks of steady use, the average odor score decreased by 3.43 points in Example 1 and 3.24 points in Example 2, confirming a remarkable deodorizing effect. On the other hand, in Comparative Example 1, the odor score decreased by 2.51 points, and in the case of Comparative Example 2, the odor score decreased by 1.76 points, making it difficult to confirm a significant effect.

In view of the above results, it was confirmed that the composition of the present invention exhibits excellent deodorizing effect and hair loss prevention effect at the same time.
