Description

Cosmetic composition containing salt and manufacturing method thereof TECHNICAL FIELD

The present invention relates to a cosmetic composition comprising salt as an active ingredient, and specifically, to a cosmetic composition capable of achieving skin moisturizing and soothing effects by including a combination of salt, purslane extract, and allantoin as an active ingredient, and a method of manufacturing the same. About.

Salt (NaCl) is an essential component for maintaining life in the human body, including not only diet, but also determines the osmotic pressure of somatic cells to enable the movement of body fluids, dissolves body proteins, and contributes to signal transmission of nerve cells. .

Salt exhibits antiseptic and sterilization effects against most microorganisms except basophils, and osmosis and dehydration functions at high concentrations. In addition, it is reported that oxygen and nutrients in the blood are transferred into the cells due to the difference in osmotic pressure in the body, and waste products generated in the cells are transported into the blood to be discharged to the outside of the body, and it is also reported to be involved in the active transport of cellular metabolites.

In anticipation of these various effects of salt, it is commercialized and sold as a health functional food as a main ingredient, quasi-drugs such as toothpaste, and food additives in the form of functional salt, but cosmetics containing salt as an active ingredient are rare. This is because if salt is not used properly, it may cause skin irritation or reduce skin moisture due to osmotic pressure. In addition, as salt is a strong electrolyte, it tends to be difficult to use as an active ingredient because it can precipitate certain components of a product or induce complex formation between components.

Accordingly, the present inventors attempted to develop a cosmetic product capable of obtaining skin moisturizing and soothing effects by using the effect of removing waste products of salt and promoting active transport of cellular metabolites.

In order to achieve the above object, one aspect provides a cosmetic composition for skin moisturizing and soothing, comprising salt, purslane extract, and allantoin as active ingredients.

Another aspect provides a method for preparing a cosmetic composition comprising mixing salt, purslane extract, and allantoin in a solvent.

One aspect provides a cosmetic composition for skin moisturizing and soothing, comprising salt, purslane extract, and allantoin as active ingredients.

The purslane extract may be one containing 50 to 60 mg/g of phenolic compounds and 20 to 30 mg/g of flavonoids.

Skin soothing may mean preventing or alleviating redness, redness, inflammation, swelling, etc. of the skin caused by external stimuli such as ultraviolet rays.

In the present specification, each extract is water, alcohol having 1 to 4 carbon atoms, ethyl acetate, glycerin, ethylene glycol, propylene glycol, butylene glycol, mineral oil, and mixed solvents thereof (e.g., hydrous alcohol, hydrous glycerin, hydrous ethylene Glycol, hydrous propylene glycol, hydrous butylene glycol). Preferably, it may be extracted using a solvent selected from water, an alcohol having 1 to 4 carbon atoms, and a mixture thereof. Here, the alcohol having 1 to 4 carbon atoms refers to methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, tert-butanol, and the like. The hydrous alcohol may contain an alcohol in an amount of 0.3 to 90 (wt/wt)%. n-butanol, iso-butanol, tert-butanol, and the like. The hydrous alcohol may contain an alcohol in an amount of 0.3 to 90 (wt/wt)%. Each extract can be prepared by a known extraction method known to a person skilled in the art. The extraction temperature may vary depending on the extraction solvent, but it is preferably 5 to 100°C.

In one embodiment, the cosmetic composition may contain 0.5 to 1.2w/w% salt, 0.1 to 0.4w/w% purslane extract, and 0.1 to 0.4w/w% allantoin based on the weight of the total cosmetic composition. .

More specifically, the cosmetic composition may include salt 1w/w%, purslane extract 0.2w/w%, and allantoin 0.2w/w%. When the content of salt exceeds the above range, the skin osmotic pressure may be affected, so that the moisturizing effect may be rather reduced, and when applied to the skin, the skin may feel irritated or tight. On the other hand, since salt, purslane extract, and allantoin are combined to exert a synergistic skin moisturizing and soothing effect, if one ingredient does not satisfy the above range, the effect of the active ingredient may be reduced.

In one embodiment, the cosmetic composition is one or more selected from the group consisting of Houttuynia Cordata Extract, Unshiu oil, sodium hyaluronate, shea butter, and dipotassium glycyrrhizate. It may further contain additional active ingredients.

Yakmo wheat extract may have a total polyphenol content of about 18 mg/g.

Unshiu oil (Citrus Unshiu Fruit Oil) is extracted from Wenju mandarin peel and may have a total polyphenol content of 5 to 8 mg/g.

Sodium hyaluronate is a moisturizing ingredient. The moisturizing component may further include those commonly known, preferably butylene glycol, dipropylene glycol, or a combination thereof.

Dipotassium glycyrrhizate is a major component of the licorice extract, and the licorice extract may be added as a dry powder.

In one embodiment, in the cosmetic composition, the extract, Unshu oil, sodium hyaluronate, shea butter, and dipotassium glycyrrhizate may be contained in an amount of 0.001w/w% to 0.004w/w%, respectively.

More specifically, Yakmomile extract, Unshu oil, sodium hyaluronate, shea butter, and dipotassium glycyrrhizate may be contained in an amount of 0.002w/w%, respectively. Yakushi extract, Unshu oil, sodium hyaluronate, shea butter, and dipotassium glycyrrhizate are the main active ingredients, salt, purslane extract, and allantoin to further enhance the skin moisturizing and soothing effects. It may be desirable to add a small amount so that the scent does not occur.

In one embodiment, as an additional active ingredient, tomato extract, rice extract, carrot extract, turnip leaf extract, broccoli extract, cabbage extract, celery extract, glycerin, caprylic-capric triglyceride, phytooligo, lecithin, ubiquinone, phyto Steryl-octyldodecyluroyl glutamate, hydroxydecylubiquinone, ceramide, caprylyl glycol, collagen (hydrolized collagen), glutathione, hollyhock extract, aloe vera leaf extract, ethylhexyl glycerin and copper peptide selected from the group consisting of A small amount of one or more, for example, the weight of each additional active ingredient is 0.001w/w% or less, specifically 0.001 to 0.0001w/w%, more specifically 0.00025w/w% based on the weight of the total cosmetic composition. Can include. The additional active ingredient may exert a synergistic effect by acting together with the existing active ingredient without reducing the efficacy of the existing active ingredient or causing side effects.

Among the additional active ingredients, copper peptide is a natural copper complex (CHK-Cu) of tripeptide glycyl-L-histidyl-L-lysine, which has a strong affinity for copper and is a complex of copper and a peptide formed as a complex salt.

Among the additional active ingredients, phyto oligo is an extract of phyto-oligo. For example, phyto-oligo is immersed in water at 5 to 40°C for 1 to 15 days to extract the mucus component, and then precipitated in ethanol. It can mean.

In one embodiment, the cosmetic composition may further include a solvent, a thickener, and a stabilizer.

The solvent may be one or more selected from the group consisting of glycerin, propylene glycol, butylene glycol, and water. Preferably, the solvent may be a mixture of butylene glycol and water. Butylene glycol may be included in about 1 to 4w/w%, preferably 2w/w%, based on the weight of the total cosmetic composition. Butylene glycol is a viscous solvent and helps to maintain an appropriate viscosity even without excessive use of a thickener.However, if it is mixed excessively, it has poor applicability and may cause osmotic irritation to the skin or discomfort when applied to the skin. have.

The thickener includes magnesium aluminum silicate, xanthan gum, dimethicone, kaolin, sepigel (a combination of polyacrylamide, C13-14 isoparaffin, and Laureth-7), but is not limited thereto. The thickener may preferably be a combination of magnesium aluminum silicate and xanthan gum. The thickener may be one containing about 1 to 4w/w%, preferably 2w/w% of each thickener component based on the weight of the total cosmetic composition, and for example, the thickener is magnesium aluminum silicate. 1 to 4w/w%, preferably 2w/w%; And about 1 to 4w/w%, preferably 2w/w% of xanthan gum. If only one thickening agent is used, the cosmetic composition may not have a soft and even appearance and may deteriorate the appearance. In particular, magnesium aluminum silicate improves the spreadability while increasing the viscosity, but does not sufficiently increase the viscosity in an appropriate dosage range, so it may be preferable to use it as a mixture with xanthan gum.

The stabilizer includes, but is not limited to, EDTA, liquid paraffin, wax, microcrystalline wax, and the like. EDTA stabilizes properties by preventing the formation of complexes between components when free metals or contaminants are present between components. Liquid paraffins and waxes can contribute to stabilizing the emulsified state of the cosmetic composition. The stabilizer may be added in an amount of 0.01 to 0.1w/w%, preferably 0.04w/w%. If the content of the stabilizing agent is too small, the stabilizing effect cannot be achieved, and if it is too large, it may rather hinder the formation of a uniform property, and in particular, the spreadability may be reduced. More specifically, the stabilizer may be EDTA-2Na.

The cosmetic composition may further include one or more selected from the group consisting of a pH adjuster, a colorant, an emulsifier, and a surfactant, if necessary.

Examples of the pH adjuster include sodium hydroxide, calcium hydroxide, potassium hydroxide, calcium hydrogen carbonate, ammonia, and triethanolamine, but are not limited thereto.

As a colorant, it is permitted to be used in cosmetic compositions, for example, annato, beta-carotene, curcumin, barium sulfate, chromium oxide green, ferrus oxide, manganese violet, anthocyanins, pyrophyllite. And the like, but are not limited thereto.

The emulsifiers include ceteayl alcohol, glyceryl monostearate, cetyl ethylhexanoate, cyclohexasiloxane, glycol stearate, cyclopentasiloxane, stearic acid, and the like. However, it is not limited thereto. remind

Surfactants include, but are not limited to, polysorbate 60, polyacrylamide, lauryl alcohol (laureth-7), sorbitan sesquioleate, and Tween-60.

The cosmetic composition may further include a preservative such as 1,2-hexanediol, and in this case, it may be 1 to 3w/w%, preferably 2w/w%, based on the total cosmetic composition.

In one embodiment, the cosmetic composition may have a pH of 6.5 to 7.5, a viscosity of 90,000 to 120,000, and a specific gravity of 0.979 to 0.999.

Viscosity and specific gravity may be measured at 25°C. If the pH is lower than this, it can cause keratin, and if it is higher, it can irritate the skin. In addition, if the specific gravity and viscosity are lower than the above range, it may be too thin to be applied to the skin, whereas if it is too high, the applicability may decrease and the marketability may decrease.

The composition of the present invention can achieve the above pH range with a combination of each component added at least 0.1w/w% as described above. Therefore, the cosmetic composition may not separately contain a pH adjusting agent as listed above.

In one embodiment, the cosmetic composition may be formulated in a form selected from the group consisting of skins, lotions, creams, essences, gels, and massage packs.

Considering the pH and viscosity that the cosmetic composition may have characteristically, it may be more preferably formulated in the form of a gel, cream, or massage pack.

Another aspect is a first mixing step of adding and mixing purslane extract to a solvent; A second mixing step of adding and mixing a stabilizer and allantoin; A third mixing step of adding and mixing a thickener; And it provides a method for producing a cosmetic composition comprising a fourth mixing step of adding and mixing salt.

In the first mixing step, the solvent may be a mixture of butylene glycol and water.

In the second mixing step, the stabilizer may be EDTA-2Na.

When sodium hyaluronate is added, it may be preferable to add sodium hyaluronate before the third mixing step, preferably in the first mixing step, since sodium hyaluronate also has a slight viscosity.

It may be desirable to add and mix additional active ingredients such as Yakko wheat extract, unshu oil, shea butter, dipotassium glycyrrhizate, and the like after the third mixing step and before the fourth mixing step. Since these ingredients are added in a relatively small amount, if added in the middle of the process, they may be lost or oxidized to deteriorate or lose efficacy.

From the first mixing step to the third mixing step, it may be performed at 40 to 60°C, specifically 50°C. In addition, the fourth mixing step may be performed at 35 to 45°C, specifically 40°C. Since the manufacturing method of the present invention does not include the step of performing at a high temperature, a preservative such as 1,2-hexanediol may be added to the first mixing step to increase the safety of the cosmetic composition.

On the other hand, it may be desirable to add salt in the last step. This is because when salt is mixed from the beginning, salt or other active ingredients affected by salt may be recrystallized in a situation where ingredients are added or temperature is controlled during manufacturing in large quantities.

If the process time is prolonged, there is a risk of contamination, and the active ingredient may be oxidized and the drug efficacy may decrease. Therefore, it may be most preferable to manufacture according to the manufacturing method as described above. In addition, the manufacturing method may be easy when mass-produced, and in mass manufacturing, for example, the total amount of the composition to be prepared is in L units, and is 1 L or more, 10 L or more, 50 L or more, for example, 1 to 100 L, It may be 1 to 50 L, 1 to 30L, 1 to 10L, or 1 to 5L.

The cosmetic composition according to one aspect has an excellent effect in supplying moisture to the skin and soothing it. In addition, the cosmetic composition has an appropriate pH, specific gravity, and viscosity, so it is easy to apply to the skin and is not irritating, so it can be easily applied to various areas.

In the method of manufacturing a cosmetic composition according to another aspect, a cosmetic composition having a uniform property can be prepared in a large amount in a short time while maintaining the effect of the active ingredient as much as possible.

Above, although the present invention has been described in detail by way of examples, the present invention is not limited to the above embodiments, and can be modified in various forms, and those skilled in the art within the technical scope of the present invention. It is clear that many variations are possible by the ruler. In addition, various types of substitutions, modifications and changes will be possible by those of ordinary skill in the art within the scope not departing from the technical idea of the present invention described in the claims, and this also belongs to the scope of the present invention. something to do.

In this test example, 10 adult women (average age 32.5) were tested for spreadability.

Each subject was allowed to test using the sense of smell, sight, or touch freely without limiting the application site of Examples 1 and Comparative Examples 1 to 5, and evaluated with a total score of 10, and the results are shown in Table 2 below. Indicated.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Average score 8.6 8.1 8.7 7.8 6.7 5.7

As a result, Example 1 and Comparative Examples 2 to 3 received a high evaluation of about 8 points, whereas Comparative Examples 4 and 5 had a significantly lower score. This was evaluated because the texture and viscosity were inappropriate.

Test Example 2: Water content test

In this test example, skin irritation and soothing effects were tested for healthy adult men and women.

Specifically, there were 20 healthy adult females, and the average age of the subjects was 35.2 years, the highest age was 48, and the minimum age was 26 years. Subjects were arbitrarily divided into 4 groups, and the moisture content of both cheeks was measured using a moisture meter (entascan), and the average was calculated. After distributing the test substances of Example 1 and Comparative Examples 1 to 3 to each group, the test substance was applied to the face twice a day for a week. During the test period, they were asked to stop drinking alcohol and to maintain the same conditions as usual for the use of sunscreen and lifestyle. After a week, measure the moisture content of both cheeks again and average them, evaluate the increase in moisture content (=% after application of test material -% before application of test material) compared to before application of test material, average each group and calculate the result. It is shown in Table 3.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Moisture increase 4.1 3.4 -1.2 1.8

As a result, Example 1 was evaluated to exhibit an excellent moisturizing effect. On the other hand, in the case of Comparative Example 2, the skin moisture content was rather reduced.

Test Example 3: Confirmation of skin irritation and soothing effect

In this test example, skin irritation and soothing effects were tested for healthy adult men and women.

Specifically, there were 20 healthy adult females, and the average age of the subjects was 35.2 years, the highest age was 48, and the minimum age was 26 years. Subjects were arbitrarily divided into 4 groups, and Example 1 and Comparative Examples 1 to 3 were divided into each group, and the test substance was thinly applied to the skin inside the arm, shielded with plastic wrap, and infrared rays were applied for 30 minutes to ensure absorption. After making it well, the skin condition (erythema, swelling, papules, etc.) was observed after 6 hours. As a result of observation, no specific skin irritation was observed in all subjects, confirming that the test substance was not toxic.

Then, in order to test the skin soothing effect, each test substance was applied to the skin inside one arm of the same test group, and Vaseline was applied to the other arm, and then UV irradiated for 20 minutes under the same conditions. Then, the skin condition was observed.

As a result, slight redness was observed on the side to which petrolatum was applied in all groups, and some testers felt itchy. On the other hand, on the side to which Example 1 was applied, erythema, swelling, etc. were not observed in all 5 subjects, but in Comparative Example 1, one of 5 subjects, and in Comparative Examples 2 and 3, two of 5 subjects had slight redness or itching symptoms. Was observed. Therefore, it was confirmed that the skin soothing effect of Example 1 is excellent.
