Solid powder cosmetic composition containing polyethylene solidifying agent

The present invention relates to a solid powder cosmetic composition having excellent sustainability against sebum or sweat while being lightly spread by containing only a solidified powder without using an oil binder or a metal salt in the powder powder.

Conventional solid cosmetics for make-up use metal salts to formulate powders in solid form, or oils such as semi-solid waxes such as ester oils, hydrocarbon oils, silicone oils, silicone gels, and butters. It has been common practice to formulate by compression molding with at least 5% dispersion of the binder. However, this method does not satisfy the cosmetic effect originally pursued makeup cosmetics. Specifically, powder powder used as a binder is generally a metal salt such as zinc stearate, magnesium myristate, and magnesium stearate, which shows a rough feeling of use and thus reduces the amount of use, and it is impossible to formulate a solid powder by itself. In the case of an oil binder, there is a limit to finely spray, disperse and disperse the oil in the manufacturing process itself, which may cause agglomeration in the solid powder. There was a disadvantage that it does not prevent the adsorption of the skin by preventing adsorption. In addition, in terms of formulation, spherical powders such as nylon, silica, PMMA, and silicone powder, which are useful for improving the feeling of use, improving sebum adsorption, and making the skin look soft, are difficult to be used in the formulation because they are difficult to compress. . When the oil binder is used too much to compensate for the above disadvantages, the surface of the solid cosmetic is covered with a thin oil film, and a caking phenomenon that is no longer buried occurs.

As a result of the study of solid powder formulation method, which prevents rough feeling of use, agglomeration and persistence deterioration of existing binders, and adds a large amount of spherical powder, it has no hardness and no powder blowing. The present invention has been completed by discovering that it can be molded into a solid powder even containing only the solidified powder.

Accordingly, an object of the present invention is to provide a solid powder cosmetic composition using only polyethylene solidification powder without using an oil binder or a metal salt.

In order to achieve the above object, the present invention provides a solid powder cosmetic composition containing 0.01 to 30.0% by weight based on the total weight of the polyethylene solidified powder in a general powder powder.

In addition, the cosmetic composition may further contain at least one spherical powder selected from the group consisting of silica (silica), PMMA, silicone resin polymer powder and nylon, the spherical powder is 1.0 to 70.0% by weight relative to the total weight of the composition It may be contained.

The solid powder composition provided by the present invention contains only polyethylene solidification powder in the powder powder generally used without other binders such as an oil binder or a metal salt, so that the solid powder can be molded into a solid powder. Excellent persistence.

The solid powder cosmetic composition of the present invention does not use an oil binder or a metal salt, and uses a polyethylene solidification powder for general powder powder.

Polyethylene solidifying powder used in the present invention is a powder powder or melting point of more than 120 ℃, the composition is 100% polyethylene wax powder. It is preferable that the average particle diameter of the said polyethylene wax powder is 2-10 micrometers, and it is more preferable that it is 3-5 micrometers. Polyethylene powder of less than 2㎛ size is rather agglomerated particles do not give uniform application and stability of the formulation, the powder size of more than 10㎛ is because the degree of solidification has a low formulation limit.

The polyethylene solidification powder is contained 0.01 to 30.0% by weight based on the total weight of the composition, more preferably 0.5 to 10.0% by weight. If the content is less than 0.5% by weight does not affect the solidification, when used in excess of 10% by weight it is preferable that the content is 10% by weight or less because the caking phenomenon that the powder is not taken in the puff in the general powder formulation.

General powder powder that can be used together with polyethylene solidification powder can use all powders generally used in cosmetics. Specifically, powder powders used are talc, mica, sericite, The type is not limited to spherical powders, enterants such as colorants, INCI, and the like.

The spherical powders are used to improve the feeling of use, increase sebum adsorption capacity, and make the skin look soft. Silica, polymethyl methacrylate (PMMA), silicone resin polymer powder, nylon, etc. may be used. . Spherical powder is difficult to use a large amount in the conventional solid powder content is about 20% by weight based on the total weight of the composition, in the present invention may contain 1 to 70.0% by weight relative to the total weight of the composition.

The solid powder cosmetic of the present invention may be prepared in the form of pressed powder, pact, pressed blusher, eye shadow, eyebrow pact, eyeliner pact and the like.

Since the present invention does not use an oil binder or a metal salt, the manufacturing method is different from the existing solid powder. Conventional solid powders are prepared through powder mixing (henschel mixer), binder heating, spraying (including fragrance, preservatives, and additives), remixing, grinding, filtration and storage, but the solid powder of the present invention It is manufactured through the process of powder mixing (henschel mixer), fragrance, preservatives and additives, pulverization, filtration and storage, thereby simplifying the manufacturing process.

Hereinafter, the present invention will be described in detail through Examples and Test Examples, but the present invention is not limited to the following Examples and Test Examples.

3) Spray 2) to mixed 1), mix with Henschel mixer, grind and store.

Examples 1 to 2 containing the polyethylene powder prepared as described above were evaluated in comparison with Comparative Examples 1 to 3 for formulation stability (hardness, drop stability), agglomeration, caking, and sustainability.

[Test Example 1]

Examples 1 to 2 and Comparative Examples 1 to 3 prepared in the above Preparation Examples were compression molded into five aluminum plates, and then hardness was measured using a hardness tester, and drop stability was tested. It evaluated as good, normal, and bad on the basis of the criteria. The test results are shown in Table 2 below.

Hardness Drop stability ^* Example 1 50 Good Example 2 55 Good Comparative Example 1 45 Good Comparative Example 2 33 Bad Comparative Example 3 50 Good

* Stability of fall: cake cracking when falling from 50cm height

(Good: No crack in 5, Normal: 1 crack in 5, Poor: 2 or more cracks in 5)

Looking at the results of Table 2, it can be seen that in Examples 1 to 2 manufactured using only polyethylene powder, satisfactory hardness and drop stability were obtained as in Comparative Example 1 using an oil binder and a metal salt. In the case of containing a large amount of spherical powder, Comparative Example 2 using a metal salt was not secured formulation stability, it can be seen that Example 2 using polyethylene powder shows excellent formulation stability.

[Test Example 2]

Thirty professional panelists in Examples 1 to 2 and Comparative Examples 1 to 3 of the above Production Example were evaluated for feeling of use, agglomeration, and caking. The worst rating was 1 and the best rating was 9, and the results are shown in Table 3 below.

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 1. Feeling 6.6 7.1 6.2 3.5 5.6 2. bunching 7.8 7.0 6.7 5.2 3.5 3. Caking 8.7 8.6 8.8 8.8 4.0 Rating: 9 out of 9

In the results of Table 3, Examples 1 and 2 and Comparative Example 1 were similar in terms of feeling. However, Comparative Example 2 using a metal salt while containing a large amount of spherical powder was evaluated to have a disadvantage in that the product is taken too much because there is a rough feeling and sufficient hardness is not secured. In addition, in terms of agglomeration, Examples 1 to 2 using polyethylene powder were evaluated to be less agglomerated than Comparative Examples 1 to 3. In terms of the caking, Comparative Example 3 using the oil binder was evaluated to exhibit a caking phenomenon due to the excess binder agglomeration.

[Test Example 3]

The oil absorption amount of Examples 1-2 and Comparative Examples 1-3 of the said manufacture example was measured, and 30 professional panelists evaluated comparatively about the persistence degree.

High oil absorption means that the persistence with respect to sebum is high, and the measuring method is as follows. Take one gram of powdered powder before compression of each formulation and drop a drop of sebum-like caprylic / capric triglyceride (hereinafter referred to as 'artificial sebum'). Then, first, as the sebum penetrates into the powder layer, the dry particles get wet (wetting), the particles agglomerate into granules by granulation. It is coalesced into a paste state, and the amount of artificial sebum injected until this moment is measured.

The degree of persistence was rated 1 as the worst rating and 9 as the best rating, and the results are shown in Table 4 below.

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 1. Oil absorption / g 0.13 0.25 0.1 0.24 0.18 2. Persistence 6.7 8.3 5.5 8.2 7.2 Panel rating: 9 out of 9

The results of Table 4 show that the case of Example 2 and Comparative Example 2, which contains a large amount of spherical powder and does not use an oil binder, has high persistence. In addition, although the content of the spherical powder is small, in the case of Example 1 using polyethylene powder, it can be seen that the sustainability is improved compared to Comparative Example 1, which is an existing product. It can be seen that there is no significant difference in oil absorption and persistence.
