Description

Cosmetic composition and cosmetic composition {COSMETIC COMPOSITION AND COSMETIC MATERIAL}

This description relates to a cosmetic composition and a cosmetic.

Reinforcing skin moisturizing power is the most fundamental of skin protection, and is the most basic function that all commercially available cosmetics and medical skin external preparations must have, and is one of the most important technologies in cosmetic technology.

The biggest indicators of skin aging are skin wrinkles and reduction of skin elasticity, and various factors such as collagen content and immunity to the external environment are known to affect the skin moisture content. .

The epidermal cells located on the outer part of the skin form a barrier to the skin to prevent the loss of moisture in the skin to promote moisture, and protect the health of the skin by preventing external harmful substances from penetrating into the skin. . The skin has a protective film that prevents moisture in the skin from evaporating, which preserves skin moisture, but the skin moisture is lost from the skin surface due to various factors such as ambient temperature and humidity, skin temperature, and stratum corneum.

When the skin barrier function is deteriorated due to the above various factors, excessive moisture loss of the skin occurs, resulting in dry skin, and in some cases, skin wrinkles may occur due to a decrease in skin elasticity. In addition, in the case of a person with atopic skin, symptoms of inflammation or itching may occur more frequently due to loss of evaporation of water in the stratum corneum due to a decrease in skin barrier function.

Under these circumstances, more and more consumers are looking for a nutritional cream, butter, and balm with high moisturizing power to care for dry skin areas. However, due to the nature of the formulation, most of the hardness is high, so it is difficult to apply to a wide area due to poor applicationability, and there is a problem of uneven application.

Accordingly, the inventors of the present invention have continued research on cosmetic compositions and cosmetics that not only can easily and evenly apply the moisturizer to a large area by increasing the application of high-hardness creams, but also boost the care efficacy by further increasing the moisturizing power of the conventional moisturizer. Came to complete.

One embodiment is to provide a boosting cosmetic composition capable of further improving application properties and moisturizing power of a high hardness cream.

Another embodiment is to provide a cosmetic composition made by mixing the cosmetic composition with a high hardness cream.

According to one embodiment, an oil phase component comprising an emulsifier and an oil; And an aqueous phase component including water, salt and polyhydric alcohol; and the salt is selected from the group consisting of sodium, calcium, magnesium, manganese and zinc, and any one cation selected from the group consisting of sulfate, chloride, and lactic acid. It provides a cosmetic composition composed of any one anion.

The salt may be salt.

The salt may be included in an amount of 2% to 30% by weight based on the total amount of the cosmetic composition.

The salt may be magnesium sulfate, manganese gluconate and calcium lactate.

As for the salt, the magnesium sulfate, manganese sulfate and calcium lactate may be mixed in a weight ratio of 1:1:1, respectively.

The salt may be included in an amount of 1% to 30% by weight based on the total amount of the cosmetic composition.

The salt may be dissociated in the aqueous phase component.

The oil may be a hydrocarbon-based oil, an ester-based oil, or a combination thereof.

The thickener may include clay minerals.

The thickener may be included in an amount of 0.1% to 2% by weight based on the total amount of the composition.

The formulation of the cosmetic composition may be an emulsified formulation or a solubilized formulation.

Another embodiment is the cosmetic composition; And it provides a cosmetic comprising a cream having a hardness of 30mN or more.

The cream may include an oily component, a silicone component, an aqueous phase component, and a viscosity modifier.

The cosmetic may contain 5 parts by weight to 20 parts by weight of the cosmetic composition relative to 100 parts by weight of the cream.

The cosmetic composition according to an embodiment stably contains a high-concentration salt and lowers the hardness of a high-hardness cream (emulsion) used in combination with it, thereby increasing the spreadability of the high-hardness cream, facilitating application, and further enhancing moisturizing power. Can be improved.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art may easily implement the present invention. However, the present invention may be implemented in various different forms, and is not limited to the embodiments described herein.

In the present specification, when a portion such as a layer, a film, a region, or a plate is said to be “on” another portion, this includes not only the case where the other portion is “directly above” but also the case where there is another portion in the middle. Conversely, when one part is "directly above" another part, it means that there is no other part in the middle.

Unless otherwise defined herein, "combination" means mixing or copolymerization. In addition, "copolymerization" means block copolymerization or random copolymerization, and "copolymer" means block copolymer or random copolymer.

Hereinafter, a cosmetic composition according to an embodiment will be described.

A cosmetic composition according to an embodiment includes an oily component including an emulsifier and an oil; Thickener; And an aqueous phase component including water, salt and polyhydric alcohol; and the salt is selected from the group consisting of sodium, calcium, magnesium, manganese and zinc, and any one cation selected from the group consisting of sulfate, chloride, and lactic acid. It is composed of any one anion.

Conventional cosmetics used for moisturizing purposes mostly have high hardness cream formulations, but these formulations have a high hardness due to their characteristics, so the spreadability is lowered, so that it is not well applied to a large area, and even when applied, it is generally applied unevenly.

According to one embodiment, by adding a cosmetic composition containing salt to a conventionally used high hardness cream formulation, the hardness of the high hardness cream is lowered to improve application properties, and at the same time, the moisturizing power of the high hardness cream itself is further improved (boost ) It is possible to provide a cosmetic composition.

The cosmetic composition according to one embodiment is composed of an oily component including an emulsifier and oil, and an aqueous phase component including water, salt and polyhydric alcohol, and can lower the hardness of the high hardness emulsion, and the increase rate of moisture content after a certain period of time is also It can be maintained high, and when prescribed with a high hardness cream having a stiff feeling that has been used in the past, it is possible to improve the spreadability of the high hardness cream and further improve the moisturizing power. Further, the water-phase component may further include polyhydric alcohol to greatly improve the preservative power and formulation stability of the cosmetic composition.

In particular, salt (NaCl) among the salts contained in the aqueous component in the cosmetic composition according to one embodiment has been known to have effects such as moisturizing, disinfecting, and improving atopic skin. When using salt as the salt, in addition to the moisturizing effect , Anti-inflammatory or antibacterial effects can be achieved.

For example, the salt may be salt (NaCl).

The salt may include natural salt, natural salt, refined salt, sea salt, earthen salt, re-decontamination, rock salt, processed salt, or a combination thereof.

The salt is dissociated in the aqueous phase component, and the term "dissociation" means that it is dissolved and separated, and the salt is dissolved in the aqueous phase component and separated into ions, and it means that the graininess of the salt crystal is lost.

For example, when the salt is salt, the salt may be included in an amount of 2% to 30% by weight based on the total amount of the cosmetic composition. When the salt is contained in an amount of less than 2% by weight based on the total amount of the cosmetic composition, the viscosity change rate is significantly lowered and the moisture content increase rate is not high, so it is difficult to lower the hardness of the high-hardness cream, and the salt exceeds 30% by weight with respect to the total amount of the cosmetic composition. When included as, the stability of the formulation decreases.

Meanwhile, as the salt, magnesium sulfate, manganese sulfate, calcium lactate, or a combination thereof may be used instead of salt. For example, the salt may be magnesium sulfate, manganese sulfate and calcium lactate. When a mixture of magnesium sulfate, manganese sulfate, and calcium lactate is used as the salt, the viscosity change rate and the moisture content increase rate are higher than when salt is used as the salt, providing a high-hardness cream cosmetic with superior application and application power. can do.

The magnesium sulfate, manganese sulfate and calcium lactate are each independently dissociated into the aqueous phase component, and the term "dissociation" means dissolving and separating, and the magnesium sulfate, manganese sulfate and calcium lactate are each aqueous phase It is dissolved in components and separated into ions, which means that the graininess of the crystal is lost.

For example, when a mixture of magnesium sulfate, manganese sulfate and calcium lactate is used as the salt, the magnesium sulfate, manganese sulfate and calcium lactate may be mixed in a weight ratio of 1:1:1, respectively.

For example, when the salt is a mixture of magnesium sulfate, manganese sulfate and calcium lactate, the salt may be included in an amount of 1% to 30% by weight, such as 9% to 30% by weight, based on the total amount of the cosmetic composition. When the mixture of magnesium sulfate, manganese sulfate, and calcium lactate is included in an amount of less than 1% by weight based on the total amount of the cosmetic composition, the viscosity change rate is greatly reduced and the moisture content increase rate is not high, so it is difficult to lower the hardness of the high-hardness cream, and the magnesium When the mixture of sulfate, manganese sulfate, and calcium lactate is included in an amount of more than 30% by weight based on the total amount of the cosmetic composition, the formulation stability is deteriorated.

The oil may include a hydrocarbon-based oil, an ester-based oil, or a combination thereof. For example, the oil may be a hydrocarbon-based oil such as natural oil, an ester-based oil, or a combination thereof.

When clay minerals are used as the thickener, salts in the cosmetic composition according to the embodiment may be stably included.

The thickener is a component that controls fluidity and affects stability when preparing a cosmetic composition according to an embodiment, and includes hectorite, bentonite, macnesium aluminum silicate, montmorillonite, quaternium-18 hectorite, Quaternarynium-18 bentonite, stearalconium bentonite, disteadimonium hectorite, or a combination thereof may be included, but the present invention is not limited thereto.

The thickener may be included in an amount of 0.1% to 2% by weight based on the total amount of the water-in-oil cosmetic composition. When the thickener is included in an amount of less than 0.1% by weight based on the total amount of the water-in-oil cosmetic composition, it is insufficient to sufficiently stabilize the trauma matrix (emulsifying component), and the thickener is included in an amount of more than 2% by weight based on the total amount of the water-in-oil cosmetic composition. In the case of manufacturing, the fluidity is greatly reduced, making it difficult to manufacture, and there is a problem that the value as a cosmetic is deteriorated due to a low feeling of use.

In addition to salts, polyhydric alcohols are further included in the aqueous phase component, and further, various water-soluble components that can exhibit skin moisturization, nutrition, feeling of use, low temperature stability, and efficacy, such as a polymer compound, urea, and moisturizer, may be included.

The aqueous component may be included in an amount of 50% to 90% by weight, such as 70% to 85% by weight, based on the total amount of the cosmetic composition according to an embodiment. When the water phase component is included in an amount of less than 50% by weight of the total amount of the cosmetic composition, there is a problem that the feeling of use of the cosmetic composition is greatly reduced, and when it is included in an amount of more than 90% by weight, low-temperature stability is greatly reduced, making it difficult to manufacture a cosmetic.

The polyhydric alcohol has an excellent effect on preservative power and can give an excellent effect on moisturizing. For example, the polyhydric alcohol is glycerin, dipropylene glycol, butylene glycol, pentylene glycol, methylpropanediol, sorbitol, diglycerin, erythritol, pentaerythritol, polybutylene glycol-10, polyglycerin-3 , Polyglycerin-4, Polyglycerin-6, Polyglycerin-10, Polyglycerin-20, Polyglycerin-40, Sorves-5, Sorves-6, Sorves-20, Sorves-30, Sorves-40 , Inositol, maltitol, maltose, mannan, mannitol, mannose, lactitol, lactose, dihydroxypropyl PG-glucoside, dithiaoctanediol, fructose, glucamine, methylglucamine, glucose, 1,2-hexane Diol, methylgluces-10, methylgluces-20, ozonizde glycerin, phytantriol, thioglycerin, traitol, trimethylolpropane, xylitol, or a combination thereof, but not necessarily limited thereto no. The polyhydric alcohol may be used in combination of two or more, or may be used alone. For example, the polyhydric alcohol may include glycerin, butylene glycol, propylene glycol, 1,2-hexanediol, or a combination thereof.

The polyhydric alcohol may be included in an amount of 1% to 20% by weight, such as 1% to 15% by weight, based on the total amount of the cosmetic composition according to an embodiment. When the polyhydric alcohol is included in the above range with respect to the total amount of the cosmetic composition, it may further increase moisturizing power and contribute to formulation stabilization.

The cosmetic composition according to one embodiment may be prepared in the form of a general emulsified formulation and a solubilized formulation. Cosmetics in emulsified form include nutrient lotion, cream, and essence, and cosmetic products in solubilized form include softening lotion. Specifically, the cosmetic composition is not limited thereto, but may have a formulation selected from the group consisting of ointments, lotions, creams, gels, solutions, suspensions, emulsions, patches, or sprays. In more detail, skin care products such as softening lotion, nutrient lotion, lotion, essence, cream, gel, pack, patch, mask, mist, make-up products such as makeup base, foundation, powder, mascara, lipstick, cleansing oil, cleansing It can be formulated as a makeup removal product such as a cream, cleansing lotion, cleansing water, and point makeup remover, and a cleaning product such as soap, cleansing foam, and body wash.

In addition to the above-described components, the cosmetic composition according to an embodiment may further include a stabilizer, a sunscreen agent, a fragrance, an antioxidant or a pH adjuster.

In addition, the cosmetic composition according to an embodiment may further include ingredients known to be effective for skin improvement, for example, disodium phenyl dibenzimidazole tetrasulfonate, diosmethine, magnesium ascorbyl phosphate, mayslignan, White extract, butylmethoxydibenzoylmethane, bis-ethylhexyloxyphenolmethoxyphenyltriazine, sucrose seed extract, acetylphytosphingosine, ascorbyl glucoside, asiaticoside, arbutin, ethylascorbylether, ethylhexylme Toxicinnamate, ethylhexyltriazone, ethylhexyl salicylate, octocrylene, oil-soluble licorice extract, peony extract, ginsenoside roe, zinc oxide, titanium oxide, polydate, polyethoxylated retinamide, franc Genidine, hydroxyproline, arbutin, homosalate, human oligopeptide-1, merirod extract, apanizominanflos aqua extract, cheonnyeoncho cactus extract, hago serrata extract, fox bead extract polyethoxylated retinamide, Polydatin, kinetin, aminobutyric acid, oligopeptide-2, white paper extract, peony extract, blueberry extract, ginseng extract or fermented sugarcane extract, etc. are included, but are not limited thereto.
