Description

Non-hydrous cosmetic compositions of bubbling pill type containing hydrophilic active ingredients

The present invention relates to a cosmetic composition of anhydrous formulations in the form of foamed (bubbling) pills (pills) containing water-soluble active ingredients, more particularly unstable water-soluble activity such as vitamin C, kojic acid, arbutin The present invention relates to a cosmetic composition of the anhydrous formulation in the form of a foamed pill which can stabilize the active ingredient by making the component in the form of a foamed pill.

Among cosmetic ingredients that have various effects on the skin, whitening and antiwrinkle ingredients are generally known as unstable ingredients. Examples include vitamin C, kojic acid, and arbutin. Among them, vitamin C is known as an excellent ingredient for whitening, wrinkle improvement, and sulfated effect, but is a representative component known to be very unstable. Therefore, cosmetic technicians have tried to stabilize the ingredients for use in cosmetics that have excellent effects.

Vitamin C tends to discolor in water. So, mainly using P / S (polyol in silicone) formulation to put vitamin C on the polyol to stabilize in emulsion form or to add vitamin C on the oil was used. When vitamin C is added to the polyol, the vitamin C is stabilized to some extent, but discoloration occurs at a high temperature due to moisture contained in the polyol, and there is a problem that discoloration occurs even when the polyol exhibits hygroscopicity. In the case of increasing the mixing of vitamin C in the oil, it is possible to stabilize the vitamin C by blocking the water supply from the outside, but there is a disadvantage that the feeling as a cosmetic becomes very bad. Another stabilization method involves simply mixing various ingredients in powder form and mixing them with the solution of the essence. In this case, the inconvenience of having to shake the powder form into the essence. In addition, when using a container in which the powder form and the essence built-in part is bounded by a thin film, there is a problem that the boundary film is weak and breaks in the impact, so that the essence liquid may flow in and discolor the vitamin C.

The present inventors have been able to solve the above problem by applying anhydrous formulations in the form of effervescent tablets using sodium carbonate or sodium bicarbonate and alpha hydroxy acid. In addition, it is possible to check the completion time of dissolving the water-soluble active substance by using it directly, to give consumers the fun by the bubbling phenomenon, and to directly control the concentration of the water-soluble substance in the emulsion by controlling the number of particles to be injected. New formulations were discovered and the present invention was completed.

Accordingly, an object of the present invention is to stabilize the unstable water-soluble active substance, the dissolution of the active ingredient spontaneously occurs in the water environment, the cosmetic composition of the anhydrous formulation in the form of an effervescent pill form that gives the convenience to easily confirm the completion point of the dissolution To provide.

Cosmetic composition according to the present invention to achieve the above object is a water-soluble active ingredient; Sodium carbonate or sodium bicarbonate; Alpha hydroxy acid; And polyethylene glycol (PEG 150).

The total weight of the composition contains 1.0 to 60.0% by weight of water-soluble active ingredient, 5.0 to 70.0% by weight of sodium carbonate or sodium bicarbonate, 1.0 to 70.0% by weight of alpha hydroxy acid, and 5.0 to 30.0% by weight of polyethylene glycol. It is preferable.

 On the other hand, the water-soluble active ingredient is characterized in that at least one selected from the group consisting of vitamin C (ascorbic acid), kojic acid (kojic acid), arbutin (arbutin), niacinamide (acetylcinamide) and acetyl glucosamine (acetyl glucosamine) However, it is not limited thereto.

In addition, the alpha hydroxy acid is characterized in that it is selected from the group consisting of malic acid (malic acid), lactic acid (lactic acid), glycolic acid (glycolic acid) and citric acid (citric acid), preferably malic acid use.

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

The cosmetic composition of the present invention has a composition different from general cosmetic compositions such as skins, lotions, creams, etc. in order to have a pill form of the foam type. In order to have effervescent properties, the water-soluble active ingredient is blended in the range of 1.0 to 60.0% by weight, preferably 10.0 to 40.0% by weight, based on the total weight. Sodium carbonate or sodium bicarbonate is formulated in the range of 5.0 to 70.0% by weight, preferably 20.0 to 40.0% by weight relative to the total weight, and alpha hydroxy acid is 1.0 to 70.0% by weight, preferably 20.0 to 40.0 relative to the total weight Compound in the range by weight. In order to form a pill, polyethylene glycol is added as a binder in a range of 5.0 to 30.0% by weight, preferably 10 to 20% by weight, based on the total weight.

Hereinafter, the configuration of the cosmetic composition of the anhydrous dosage form in the form of an expanded tablet according to the present invention, and a method for preparing the same will be described in more detail with reference to Examples and Test Examples. However, the present invention is not limited to these examples.

As described above, the preparation of the cosmetic composition in anhydrous form in the form of an effervescent (bubbling) pill (fill) by using sodium carbonate, alpha hydroxy acid, and polyethylene glycol It is possible to produce a foamed pill (bubbling pill) having a so-called bubbling phenomenon by generating bubbles by pouring the foamed pill into the milk accordingly. Foamed pills (bubbling pills) are capable of stabilizing unstable water-soluble active ingredients in the form of particles without moisture. In addition, the bubbling phenomenon not only visually informs the point of dissolution of the water-soluble active ingredient contained in the bubbling pill, but also shows that the product can be visually differentiated. Since it is made in the form of a simple pill (pill), it is possible to control the concentration of the active ingredient in the emulsion by controlling the number of pills (pill), it can be seen that it also has the advantage of widening the concentration range that consumers can use themselves.
