Description

[0001] The present invention relates to a dry cosmetic composition comprising a natural material and a natural cosmetic pack containing the natural dry cosmetic composition,

The present invention relates to a dry cosmetic composition for natural materials and a natural cosmetic pack containing the same. More particularly, the present invention relates to a natural cosmetic composition comprising a natural material dried product as an active ingredient, a super absorbent starch and a hygroscopic saccharide added thereto, It is possible to maintain stability for a long period of time by minimizing discoloration and deterioration of the product while improving the preservation period while being an effective ingredient and mixing with a liquid medium such as water at the time of use to easily form a gel form having excellent skin application properties and appearance, To a dry cosmetic composition of a natural material capable of providing an excellent moisturizing effect, a softening effect, and an effect of improving skin tone and transparency when applied to a cosmetic pack containing the same.

When the skin is affected by internal and external factors such as season, environment, age, ultraviolet rays, etc., the basic function of the stratum corneum is lowered water retention and skin protection function, which increases skin moisture loss and makes the skin rough and dry. It causes aggravation or aging. Therefore, in order to maintain a healthy skin condition, various methods of moisturizing and moisturizing the skin using various moisturizing cosmetics are required, and the skin root function is strengthened to suppress skin moisture loss.

Pack cosmetics form a moisturizing film on the skin to suppress moisture evaporation to the outside, temporarily moisturize and moisturize the skin, and deliver effective ingredients derived from various natural materials to the skin for a long time. There is a growing interest in pack cosmetics.

Along with naturalism trends such as natural and organic, consumer interest in unprocessed natural cosmetics has become very high, and a number of products have been introduced that have beneficial effects on skin by utilizing the advantages of various natural materials Japanese Patent Application Laid-Open Nos. 10-2008-0033668 and 10-2013-0050175). Natural household goods such as yulmu, cucumber, egg, honey, and milk are used in general households, and natural packs are widely used in everyday life, such as making skin packs for personal care.

As reflected in these trends, pack cosmetics containing natural materials have been recently launched on the market, but most of the natural packed cosmetics have a problem in that, due to the formulation characteristics of a gel or cream type containing water, Or hydrolysis phenomenon to cause discoloration such as discoloration and deterioration when stored for a long period of time, and the stability of the formulation is impaired.

In order to compensate for this phenomenon, powdered natural packs have been introduced. However, since they have low viscosity when mixed with water, there is a problem that they are not easily used, for example, they are applied or slipped down when applied to the skin. In case of the powder pack product to which the viscosity is applied, there is a problem that it is inconvenient to use due to the phenomenon that the gum components are bundled without being properly dispersed when mixed with water.

Therefore, it is required to develop a dry cosmetic composition which is excellent in long-term storage stability while containing a natural material as an effective ingredient, minimizes problems such as discoloration and sweating, and is excellent in skin application when used as a pack.

Hereinafter, the present invention will be described in detail.

The dry cosmetic composition of the present invention comprises (A) a natural material dried material as an effective ingredient.

The dried material of the natural material can be used alone or in combination with those which can be used as an effective ingredient in the field of cosmetics (for example, fruits, vegetables, herbs, herbal materials, seeds and original plants of these materials) The term " dried material of natural materials " is a concept including all of the above-mentioned ones, as well as other naturally occurring dry materials which are useful in skin cosmetics and which are useful for skin. There is no particular limitation on the method for producing the dried material of the natural material as the effective ingredient of the present invention from such natural materials. For example, the raw natural material itself or the extract thereof is dried by a method such as natural drying, hot air drying, cold air drying, steam drying, vacuum drying, vacuum freeze drying, vacuum drying at low temperature, and the resultant is pulverized, Granulation or the like to reduce the size of the particles, thereby making it possible to produce a dried material of a natural material. There is no particular limitation on the particle size of the manufactured natural material powder. For example, the particle size of the natural material powder may be suitably adjusted according to the intended use within a range of 10 to 3,000 mu m, but the present invention is not limited thereto. ) Can also be used.

The dry cosmetic composition of the present invention contains 0.1 to 90 parts by weight, preferably 0.5 to 80 parts by weight, more preferably 1 to 60 parts by weight, of the dried material of the natural material based on 100 parts by weight of the total composition. If the content of the dried material is less than 0.1 part by weight per 100 parts by weight of the composition, the effect of improving the skin is reduced. When the amount of the dried composition is more than 90 parts by weight, the dispersibility of the dry composition in the liquid medium is deteriorated, There is a drawback that the skin application property is poor.

In addition, the dry cosmetic composition of the present invention comprises (B) a superabsorbent starch.

The superabsorbent starch is preferably a starch which exhibits a water absorption rate of 10 to 500 times by weight (i.e., absorbing 10 to 500 g of water per 1 g of starch), and exhibits a water absorption rate of 50 to 400 times , And absorbing 50 g to 400 g of water per 1 g of starch). If the absorption capacity of the superabsorbent starch is lower than the above level, the viscosity may not be formed properly when the dry composition and the liquid medium are mixed, and the viscosity may be lowered. On the other hand, if the absorption capacity is too high, There may be a disadvantage of poor application (that is, not spreading well on the skin).

In the present invention, 'superabsorbent starch' refers to a modified starch modified by physically, chemically or biologically treating a common raw material starch and exhibiting a water absorption rate of 10 to 500 times by weight (that is, absorbing 10 g to 500 g of water per 1 g of starch Quot; starch "). As the superabsorbent starch, denatured starch modified by physically, chemically or biologically treating raw starch may be preferably used which exhibits the above-mentioned water absorption rate. Specific examples of the raw starch include, but are not limited to, whole grains or starch of rhizomes including corn, waxy corn, tapioca, potato, sweet potato, rice and glutinous rice, and specific examples of the physical, chemical or biological treatment Examples thereof include heat treatment, acid treatment, alkali treatment, enzymatic treatment, alkylation, acetylation, esterification, etherification, phosphorylation, crosslinking, and alpha-modification. Examples of the modified starch include alkylated starch, acetylated starch , Esterified starch, etherified starch, phosphorylated starch, crosslinked starch, and alpha starch. These modified starch salt forms are also included in the superabsorbent starch usable in the present invention. Such superabsorbent starch acts as a pre-denaturant for improving hydrophilicity, and forms a cosmetic pack form suitable for skin application by forming a suitable viscosity quickly when mixed with a liquid medium (for example, water) for forming a cosmetic pack . According to a preferred embodiment of the present invention, the superabsorbent starch is selected from the group consisting of crosslinked sodium polyacrylic acid starch, sodium carboxymethyl starch, hydroxypropyl starch, hydroxypropyl phosphate starch, hydroxypropyl oxidized starch and mixtures thereof Selected modified starches may be used.

In the powdery or dry state, the particle size of the superabsorbent starch is preferably 1 to 200 탆, more preferably 10 to 150 탆. If the particle size of the superabsorbent starch is excessively smaller than the above-mentioned level, there is a problem that the particles are excessively dusty, which is cumbersome and inconvenient to use. Conversely, if the particle size is too large, And it may be disadvantageous to give uncomfortable feeling when applying the skin.

The dry cosmetic composition of the present invention contains 1 to 20 parts by weight, preferably 3 to 15 parts by weight, more preferably 5 to 15 parts by weight of the superabsorbent starch based on 100 parts by weight of the total composition. If the content of the superabsorbent starch is less than 1 part by weight per 100 parts by weight of the total composition, there is a problem that an appropriate viscosity can not be formed when the cosmetic pack is formed and flow down. When the amount is more than 20 parts by weight, the viscosity becomes too high, , Not spread well on the skin).

According to a preferred embodiment of the present invention, when the dry cosmetic composition of the present invention has a weight ratio of (A) the natural material dried material: (B) the superabsorbent starch of 1: 0.5 to 1:16, It is possible to obtain an effect of excelling in pack characteristics and skin coverage.

In addition, the dry cosmetic composition of the present invention comprises (C) a hygroscopic saccharide.

The 'hygroscopic saccharide' in the present invention is a saccharide used in cosmetics having a powdery hygroscopic function, and has a high hygroscopicity when blended with a liquid medium, thereby helping to improve skin moisturizing ability, Means a cosmetic material having a function of accelerating the dissolution of the natural material to improve the solubility of the dried natural material.

Examples of hygroscopic saccharides usable in the present invention include monosaccharides, polysaccharides (including oligosaccharides), sugar alcohols, and mixtures thereof, and more specifically polyglycitol, maltitol, inositol, sorbitol, mannitol, xylitol, erythritol , Glucose, fructooligosaccharide, betaine, trehalose, raffinose, fructose, dextrin, and mixtures thereof can be preferably used. More preferably, sugar alcohols selected from the group consisting of polyglycitol, maltitol, inositol, sorbitol, mannitol, xylitol, erythritol, and mixtures thereof can be used.

The dry cosmetic composition of the present invention contains 5 to 90 parts by weight, preferably 10 to 90 parts by weight, more preferably 20 to 80 parts by weight of the hygroscopic saccharide based on 100 parts by weight of the total composition. If the content of the hygroscopic saccharide per 100 parts by weight of the composition is less than 5 parts by weight, the skin moisturizing effect is low and the hydration time of the superabsorbent starch is not improved. If the amount is more than 90 parts by weight, There is a disadvantage of bad sex (that is, not spreading well on the skin).

According to a preferred embodiment of the present invention, when the dry cosmetic composition of the present invention has a weight ratio of (A) a natural material dried material: (C) hygroscopic saccharide in a weight ratio of 1: 0.02 to 1:20, It is possible to obtain an effect of improving the properties of the skin and the skin application.
