Description

[0001] The present invention relates to a mask pack composition providing an emulsifying function during use,

The present invention relates to a mask pack composition to which an emulsifying function is imparted in use, and more specifically, to a mask pack composition comprising: a) an O / D phase composition containing a surfactant, a polyol, and an oil; And b) separating the wet-impregnated non-woven fabric from the W-phase containing water and a moisturizing component.

In addition to the basic aging factors, modern people are suffering from severe external skin damage due to contaminated external environment, stress in daily life, and increasing frequency of use of makeup products. In order to overcome this, various skin care products such as lotion, cream, and essence are used and dermatological treatment is utilized. However, the use of general skin care products is limited in skin penetration due to the nature of the skin tissue, and it is difficult to expect immediate skin improvement. This leads to relatively dangerous procedures such as expensive dermatological treatment and drug treatment. Therefore, basic cosmetics that are effective in skin infiltration but relatively safe and inexpensive are needed.

In recent years, the development and consumption of various types of masks with enhanced functions have been actively pursued. The mask formulation is divided into a type that is largely washed and a type that is absorbed into the skin without being washed. The washable type is a method to give the skin enough function when used such as a mud pack or gypsum pack, and not to leave it on the skin after use. The non-washable type is a type in which the contents are deposited on a nonwoven fabric or a gel-like support, which is easily attached to the face and removed.

The double sheet type mask is advantageous because it is easy to use and the large amount of essence can be exposed to the skin for a long time because the face sheet is attached to the face without using the hand.

The composition of the contents currently applied to the mask sheet is mostly composed of a water-soluble material. In the case of the water-soluble type, various skin types and age groups are preferred because it is advantageous in feeling of moisture and feeling of freshness. However, most of the composition is composed of water-soluble components, which makes it difficult to penetrate the outermost layer of the skin structure composed of the skin, and it is difficult to provide the oil required for the skin. Therefore, since it is difficult to expect a skin moisturizing effect for a long time after use, it is easily dried, and there is an inconvenience that an emulsifying agent such as lotion or cream containing an oil-soluble ingredient should be additionally used. In the case of the emulsification type, it is possible to contain a large amount of oil, so that sufficient nutrition can be given to the skin. However, it is difficult to have stability of low viscosity capable of uniformly depositing on a support such as a sheet or a gel. The skin absorption may not be easy.

Korean Patent No. 10-0739386 discloses a mask composition containing an emulsified liquid composition and describes an emulsion type mask sheet composition. However, the above-mentioned prior art patent is a general emulsion formulation and does not mention the emulsion particle size , And the usage is also significantly different from the present invention.

Based on the foregoing, there is still a need for a mask pack composition that provides a superior skin-improving effect, and a mask pack composition that provides moisturizing effects, particularly moisturizing, of the skin. None of the existing techniques provide all the advantages and effects of the present invention.

Accordingly, the present inventors have made intensive investigations in order to overcome the problems of the prior art, and as a result, they have found that a) an O / D phase composition containing a surfactant, a polyol, and an oil; And b) a mask pack composition comprising a wet-impregnated non-woven fabric separated from a W-phase containing water and a moisturizing component, wherein a) and b) are sequentially applied to the skin in any order so that spontaneous D-phase emulsification And thus, it is possible to provide an excellent emollient of fresh fine particles produced on the skin to the skin, thereby providing an excellent moisturizing and moisturizing effect, thus completing the present invention.

Accordingly, it is a main object of the present invention to provide a mask pack composition or a cosmetic composition, which has an excellent emollient effect on the skin by spontaneously emulsifying D-phase immediately, Mask pack to provide cosmetics.

According to one aspect of the present invention, the present invention provides a mask pack composition comprising the following a) and b) separately.

a) an O / D phase agent comprising a surfactant, a polyol, and an oil; And

b) a non-woven fabric impregnated with 2 layers of W phase containing water and a moisturizing component.

Conventionally, a composition immersed in a mask sheet is mostly water-soluble, which makes it difficult for an efficacious ingredient to penetrate into the skin, and an emulsifier type composition is difficult to have low viscosity stability capable of evenly depositing on a support such as a sheet, In case of large particle size, skin absorption was not easy. Accordingly, the present inventors have invented a mask pack composition which solves the above problems, provides a skin moisturizing effect and a moisturizing effect, thereby exhibiting an excellent skin improving effect.

In the present invention, the above a) and b) are sequentially applied to the user's skin or face. The order in which they are applied is irrelevant.

Conventionally, in order to use an emulsion formulation as a mask, the emulsified form is immersed in a sheet to be used as it is by a consumer. However, the present invention is characterized in that an O / D phase which is not emulsified and a liquid composition are separated And it was made into a form in which emulsification was completed as a result of applying it sequentially to the skin. In general, in order to produce emulsions of fine particles, it is necessary to have expensive production facilities and, even in the case of producing general emulsions, a long time manufacturing process must be performed through a separate emulsifying production mixer. On the other hand, the composition of the present invention can form emulsions of fine particles without the expensive manufacturing facilities as described above because of the morphology in which the emulsification is performed by the consumer. Also, according to the taste of the consumer, there is an advantage that the use feeling and the oiliness can be controlled by varying the amount of the O / D phase to be applied.

In the present invention, the above a) and b) are applied to the skin or face and then rubbed with a finger or a palm.

The rubbing is characterized in that the D phase emulsification reaction occurs by mixing the O phase of 1) and 2 of the W phase of b).

In the present invention, the O / D phase refers to a gel phase formed by dispersing an oil phase in a mixture of emulsifiers. That is, it is an oil-in-surffactant form which is made by adding a large amount of oil to a phase containing a detergent.

In the present invention, the W phase refers to an image containing water required to meet an O / D phase and make an O / W emulsion. In addition to water, it may contain other moisturizers such as polyol, vegetable extract, and hyaluronic acid.

In the present invention, D-phase emulsification means that when oil is slowly added to D phase (surfactant and polyol added phase), high viscosity gel is formed through O / D form, and water (W Phase) is added to make a low-viscosity O / W emulsion of fine particles.

As described above, since the present invention separates a) and b) from each other and allows the user to directly mix and emulsify the skin, it is applied to the skin or the face and rubbed to cause the emulsification reaction, To be absorbed by the skin.

In the present invention, the mask composition is characterized by excellent form stability. According to the present invention, since a D-phase emulsion is formed on-the-fly at the time of use, a separate emulsification process is not necessary and a quality deterioration such as separation, precipitation and oxidation of the emulsion is prevented during the storage period before use So that the formulation stability is excellent.

In the present invention, the mask composition is characterized by being excellent in moisture retention and skin absorbency.

The water-soluble substances added to the mask sheet are hardly penetrated into the skin tissue. The emulsifier type is difficult to deposit evenly on the mask sheet. The general emulsion has a large particle size, Since the emulsifier a) and the liquid composition b) are separately separated and emulsified after application to the skin, small-sized particles can be uniformly absorbed on the skin, so that the formulation stability is excellent. Of the composition is uniformly absorbed to the skin, so that it can be said to be excellent in the ability to absorb and moisturize the skin because it can increase the moisture resistance.

According to the experimental example of the present invention, when the O / D phase and the liquid composition are sequentially used in the order of the deposited sheets, the appearance of the transparent contents immediately coated on the face changes to milky white, Respectively. In addition, the emulsion particles produced in this process could be obtained with a fine particle size of nano-micro level.

As described above, according to the present invention, the mask pack composition of the present invention can be applied to skin with comparatively inexpensive price and excellent feeling through simple use of D-phase emulsifier type which is hard to commercialize, The skin improvement effect is also excellent.
