Description

Cosmetic comprising a pad carrying a powder {Cosmetic comprising pad containing powder composition}

The present invention relates to a cosmetic in the form of a pad containing a cosmetic composition of the powder property, comprising a cosmetic composition in a functional pad that is a carrier of the contents of the powder property and at the same time function as an applicator, while improving the convenience for application of the cosmetic, The present invention relates to a cosmetic having enhanced cosmetic effects.

Conventional cosmetic compositions have generally stored or used cosmetics using plastic, glass containers. In addition, the functional raw material for skin care purposes was preserved by using a closed or separated double container or stabilizing the active ingredient from other ingredients until stabilization of the active ingredient until just before use, depending on the type. In particular, when the active ingredient separated and preserved is in the form of powder, the active ingredient in powder form was dissolved and used before use.

At this time, the powder must be mixed with the liquid to dissolve, since at least 5-7 days of liquid mixture is produced, the stability of the active ingredient dissolved in a large amount is a problem, and for continuous use dissolve the powder at least 5-7 days It was not so easy to use.

On the other hand, in order to apply the cosmetic to the skin, hand, cotton puff, applicator and the like are generally used.

Therefore, in order to apply the active ingredient separated and preserved in powder form to the skin, in addition to dissolving the powder, the mixed solution should be applied by hand or wetted with a pad, so that it is troublesome to go through several steps until skin application.

In addition, in the case of functional cosmetics containing the active ingredient to be used for skin care purposes, the optimum activity and the best cosmetics of the contents greatly affect the skin care effect. Therefore, there is a need for an applicator carrying cosmetics directly in order to effectively and conveniently use it while keeping the active ingredient stable.

Korean Patent Publication No. 2011-0001233

Therefore, the inventors of the present invention intend to provide cosmetics in which the functions of the applicator and the container are integrated so that they can be easily applied to the skin without having to dissolve the active ingredient in powder form every time.

Therefore, an object of the present invention is to provide a cosmetic which can conveniently use the functional raw material of powder property.

In order to achieve the above object, the present invention provides a cosmetic comprising a pad carrying a powder.

Cosmetics of the present invention do not need to mix the powdery cosmetics with the liquid for applying the skin, and does not require a separate tool for applying the skin, it can be conveniently used for one use.

The cosmetic product of the present invention includes a pad which functions as an applicator for facilitating application of cosmetics while functioning as a container for carrying the active ingredient.

In the present invention, the active ingredient to be used is a functional raw material used for the purpose of skin care, and is not particularly limited as long as it can be formed into a powder, and specifically, niacinamide, arbutin, melasolve, vitamin derivatives, and the like. Include. In addition, to improve the solubility in the liquid phase, the active ingredient used in the present invention is prepared in powder form through a crystallization or lyophilization process using sugar.

In addition, the cosmetic product of the present invention includes a pad that serves as a container for carrying the active ingredient of the powder form. The material of the pad is not particularly limited, but may be a natural fiber such as cotton (cotton), or a synthetic fiber such as viscose rayon, nylon, and the like, particularly preferably a cotton, and the powder dissolves in the liquid phase and then elutes well to the skin. In order to achieve this, the surface of the pad has a double layer structure of cushioning and dissolution (FIG. 1).

In addition, the pad used in the present invention may include lanseal, which is a composite functional fiber, to quickly absorb a large amount of water. Lansil has a two-layered structure with a superabsorbent outer layer and an inner layer of acrylic fiber, which combines the functions of superabsorbent resins with physical properties as a fiber. As a result, water is quickly absorbed to facilitate dissolution of the impregnated powder.

In addition, since the pad containing the lancil absorbs the liquid and gels, the pad has excellent adhesion to the skin, and the cosmetic may be gently applied to the skin. In one embodiment of the invention, the lancil may be contained in an amount of at least 20% by weight, preferably at least 30% by weight, more preferably at least 40% by weight, even more preferably at least 50% by weight relative to the total weight of the pad. Can be. Further, in one embodiment of the present invention, the amount of lancil is 90% by weight or less, preferably 80% by weight or less, more preferably 70% by weight or less, even more preferably 60% by weight or less, based on the total weight of the pad. It may be contained as. In another embodiment of the present invention, the lancil is 20 to 90% by weight, preferably 30 to 80% by weight, more preferably 40 to 70% by weight, even more preferably 50 to 60% by weight of the pad total weight. It may be contained in an amount of% by weight. If the content is less than 20% by weight, the liquid absorption and water holding power are not only weak, but the softness is weak. If the content is more than 90% by weight, the water holding power is too high, so it is not easy to discharge the liquid cosmetic to the skin. You may not.

Cosmetics of the present invention is a cosmetic composition is contained in a pad, the pad used is a type of compressed several layers of fibers (Fig. 2), a type of pad having a film on one side to give the direction of application of the contents (Fig. 3), hand Thimble pad type (FIG. 4), etc. At this time, in the case of the coating type, when the pad absorbing the lotion is held by hand, the contents are prevented from leaking toward the hand and the contents are spilled toward the skin. Thimble type is used by inserting the fingers, to improve the uniform application of the cosmetics to be used, and to apply a close feeling to enhance the effect of the cosmetics. All of these types take the form of filling a small amount of powder between the thin pad and the pad and pressing the pads on both sides to form a space in which the appropriate amount of powder can be present.

Although the amount of the powder supported on the pad of the present invention is not particularly limited, it is generally appropriate to carry 0.03 to 1 g of powder per pad in consideration of the amount applicable to the skin in a single use. In addition, the amount of the liquid used to dissolve the powder is suitable for 0.5 ~ 2.0g considering the amount of the powder and the amount of powder that can be applied to the skin in one use.

As described above, the pad type carries an active ingredient in powder form therein, and can be used directly as an applicator after the pad is soaked in a liquid phase, and thus is easy to use. In addition, since it is divided by once, it is also possible to solve the problem of instability of the dissolved active ingredient, and the pad carrying the powder is discarded after one use, so that the problem of contamination of the pad and repeated washing due to repeated use can be solved.

The liquid phase used to dissolve the powder supported on the pad of the present invention is not particularly limited in kind and characteristics, and may be used as long as it can dissolve the powder so as to be applied to the skin.

Hereinafter, the present invention will be described more specifically based on the following examples and test examples.
