Description

[0001] The present invention relates to a nighttime oil-in-water emulsion type cosmetic composition containing an organic plant-derived component,

The present invention relates to a chestnut oil-in-water emulsified cosmetic composition having an excellent emulsion stability while containing a large amount of organic plant-derived butter.

The skin is divided into three layers: epidermis, dermis, and subcutaneous fat tissue. It protects against external stimuli and controls the evaporation of about 65-70% of the human body's water. The epidermis of the skin is divided into the stratum corneum, the granular layer, the superficial layer, and the basal layer in order from the outside. Among them, the stratum corneum of the epidermis contains approximately 10 to 20% of water, and the sebaceous glands from the sebaceous glands and the thin It is enclosed with a natural protective film, and functions to prevent water evaporation from the outside of the body and to prevent penetration of foreign substances.

However, these stratum corneum is easily lost due to environmental factors such as lifestyle factors such as cleansing and bath, dry air pollutants, and endogenous diseases such as atopic and senile skin, As it occurs, the skin becomes dry, the surface becomes rough, and the appearance of gray appears. Furthermore, the function of sebaceous glands and sweat glands is reduced, and the amount of sebum and sweat released is reduced, resulting in a failure to produce a natural protective film, losing protection against skin hydration, and drying the skin. Such a skin moisturizing function deteriorates the elasticity of the skin, and furthermore it becomes a main factor of skin aging. Therefore, a skin moisturizing composition is required. To meet this demand, various moisturizing cosmetics have been researched and used to maintain proper skin moisture.

In the case of general moisturizer cosmetics, various non-soluble substances such as water-soluble ingredients, oil-soluble ingredients and other ingredients such as water-soluble ingredients, other ingredients and the like are mixed as effective ingredients for moisturizing, protecting and skin health of the skin. Especially, It is difficult to increase the proportion of the hydrophilic component to be converted. In order to increase the proportion of the lipophilic component, it is necessary to add a surfactant component or to add an additional emulsion stabilizer.

However, in the case of the cosmetic composition in which the conventional moisturizing effect which is commonly used is improved, allergic, atopic and dermatitis are caused by containing a chemical synthetic component as an active ingredient.

Accordingly, in order to solve such a problem, a cosmetic composition having an improved moisturizing effect by containing a component derived from an organic plant as an active ingredient in accordance with a well-being trend has been developed.

For example, Korean Patent No. 10-1242371 discloses a skin moisturizing cosmetic composition which contains an organic plant-derived ingredient, shea butter, as an active ingredient, which prevents drying of the skin and smoothes the texture of the skin, unlike the conventional chemical synthetic ingredients .

However, in the case of the composition containing the butter derived from the organic plant, the oil component is separated from the surface of the formulation in a high temperature environment, so that the feeling and stability are lowered compared with the composition containing the existing chemical synthesis component as an active ingredient I have a problem. In addition, the emulsifier added to improve the stability of the cosmetic composition in which the separation phenomenon occurs as described above has a problem that it contains a chemical synthetic component rather than a natural component as an active ingredient.

In order to solve such problems, it is desired to develop a skin moisturizing cosmetic composition having excellent formulation stability while eliminating the existing chemical synthetic components.

Therefore, the present inventors have made various efforts to have excellent emulsion stability while containing a large amount of organic plant-derived butter. As a result, it has been found that the emulsion stability of a formulation is improved when a polyglycerin fatty acid ester emulsifier and a plant- Thereby completing the invention.

Accordingly, an object of the present invention is to provide a night-type oil-in-water emulsion type cosmetic composition which is excellent in skin stability and moisturizing durability and has improved emulsion stability of a formulation.

In order to achieve the above object, the present invention provides an oil-in-water emulsion type cosmetic composition comprising an aqueous phase and an oil phase, wherein the oil phase comprises organic plant-derived butter, vegetable oil, polyglycerin fatty acid ester emulsifier, Oil-in-water emulsion type cosmetic composition.

The night type oil-in-water emulsion type cosmetic composition of the present invention is excellent in skin stability and moisturizing sustainability, and is excellent in emulsion stability of the formulation.

Fig. 1 is a photograph of each formulation after the results of the formulation stability test of Example 1 and Comparative Example 2. Fig.

Hereinafter, the present invention will be described in more detail.

The night-type oil-in-water emulsion type cosmetic composition according to the present invention is an oil-in-water emulsion type cosmetic composition comprising an aqueous phase and an oil phase, wherein an organic plant-derived butter, a polyglycerin fatty acid ester emulsifier, a plant- .

The organic plant-derived butter of the present invention may be selected from the group consisting of Shea Butter, Cupuacu Butter, Cocoa Butter, Peach Butter, Murumuru Butter, Aloe Butter ), Pistachio Butter, Avocado Butter, Mango Butter, Soy Butter, Almond Butter, Olive Butter, Wheat Germ Butter, ), Jojoba Butter, Macadamia Seed Butter, Apricot Butter, Grape Seed Butter, Hemp Butter, Illipi Butter, Kokum Butter, and Sal Butter are used in the present invention.

The plant-derived butter is a vegetable oil which improves moisturization of the skin. In the present invention, it is not limited to any one of the plant-derived butter components, but it is preferable to use shea butter.

Such organic plant-derived butter is preferably contained as an active ingredient in an amount of 0.1 to 20% by weight based on the total weight of the cosmetic composition. If it is less than 0.1% by weight, the skin moisturizing and soothing effect is insignificant. If it exceeds 20% by weight, the increase of the effect is not so large as compared with the content increase, and the formulation stability of the composition may be problematic.

The vegetable oil of the present invention serves as an oil-soluble solvent in cosmetic compositions and can be used as a solvent for cosmetics such as olive oil, medowfoam oil, rosehip oil, avocado oil, camellia oil, Castor oil and Hojoba oil. It is preferable to use one of them.

The content of the vegetable oil is preferably 1 to 3% by weight based on the total weight of the night-type oil-in-water emulsified cosmetic composition as an active ingredient. If the content of the vegetable oil is less than 1% by weight, the hardness as the night-type formulation can not be obtained. If the content is more than 3% by weight, it is burdensome to use on the skin and the long-term stability is rapidly deteriorated. desirable.

In particular, in the present invention, the formulation stability of a night type cosmetic composition having a high hardness is secured by using a polyglycerin fatty acid ester emulsifier and a plant-derived emulsifier together in the oil portion.

The polyglycerin fatty acid ester type emulsifier is an emulsifier obtained by esterifying various high fatty acids with polyglycerin obtained by heating dehydration condensation of glycerin with alkali catalyst. The polyglycerin fatty acid ester emulsifier is a component having high stability to the skin and the human body, and functions to increase the hardness and to impart the fixation.

Wherein the polyglycerin fatty acid ester emulsifier is selected from the group consisting of polyglyceryl-10 laurate, polyglyceryl-diisostearate, polyglyceryl-3 methyl glucose distearate, polyglyceryl-2 laurate, polyglyceryl- Stearate, polyglyceryl-2 caprate, polyglyceryl-3 laurate and polyglyceryl-4 isostearate, and polyglyceryl-3-methylglucoside distearate It is more preferable to adopt the rate.

The polyglycerin fatty acid ester emulsifier preferably contains 3 to 20% by weight based on the total weight of the cosmetic composition as an active ingredient. If it is less than 3% by weight, the hardness is lowered, so that it is difficult to prepare the night-type composition of the present invention. When it is more than 20% by weight, there arises a problem that the particles are bundled together during storage for a long time and causes skin irritation due to excessive use .

In the present invention, a plant-derived emulsifier is added instead of a chemical synthetic ingredient such as a conventional silicone oil, polyethylene glycol (PEG), or polypropylene glycol (PPG), so that a feeling of use with good texture and a smooth viscosity can be expressed, Is reduced. The plant-derived emulsifier according to one embodiment of the present invention is hydroxystearyl alcohol / hydroxystearyl glucoside (Hydroxystearyl alcochol & Hydroxystearyl glucoside).

Hydroxystearyl alcochol & Hydroxystearyl glucoside lowers the interfacial tension of organic plant-derived butter due to hydroxystearyl alcohol from pajama seeds and hydroxystearyl glucoside from wheat Emulsified particles are easily produced, and stability is imparted to the produced system, thereby producing hardness of the night-type cosmetic composition.

The hydroxystearyl alcohol / hydroxystearyl glucoside is preferably used in an amount of 1 to 10% by weight based on the total weight of the cosmetic composition. If it is less than 1% by weight, the stability of the formulation and the hardness of the night-type cosmetic composition can not be expected. If it exceeds 10% by weight, the viscosity of the raw material and the formulation is too high, .

In the present invention, since an organic plant-derived component that has been certified as stable instead of a conventional chemical synthetic ingredient is contained as an active ingredient, problems caused by the addition of conventional chemical synthetic moisturizing and emulsifying ingredients are improved and excellent moisture retention ability is obtained.

Preferably, the ratio of each composition constituting the night-type oil-in-water emulsion type cosmetic composition of the present invention satisfies 100 wt%

The content of the moisturizing agent is 1 to 10% by weight in the whole cosmetic composition. If the content of the moisturizing agent is less than the above range, it is difficult to expect a sufficient moisturizing effect. On the other hand, when the content exceeds the above range, the content of the other composition is decreased and the effect thereof can not be secured. .

The thickening agent is used in the night-type cosmetic composition to impart an appropriate viscosity to enhance the feeling of use, and one kind selected from xanthan gum, natural cellulose, carbomer, gelatin, high-cell, methyl cellulose and a combination thereof can be used It is preferable to use xanthan gum.

The content of the thickening agent is preferably 0.02 to 2% by weight in the entire cosmetic composition. If the content is less than the above range, it can not be hard enough to form the night-type composition of the present invention. On the contrary, when the content exceeds the above range, the hardness is too high and is not suitable for cosmetic application. Is preferably used.

The water is distilled water, preferably deionized distilled water.

The cosmetic composition according to the present invention may further contain a polyhydric alcohol in the oil phase part.
