Description

[0001] The present invention relates to a pressed cosmetic powder composition comprising starch and kaolin,

The present invention relates to a compressed powder cosmetic composition for infants comprising starch pulverized by high-pressure air flow and kaolin.

In the human skin, the stratum corneum and sebum act as barriers to the external environment. In babies, the keratin layer is thinner, more watery, and less sebum distributed than adult skin. For this reason, baby skin is less resistant to physical or chemical stimuli from the external environment. Particularly, the frequent occurrence of a sweaty tendon in a baby's skin which is vulnerable to external stimuli occurs mainly in the nape of the infant's neck, underarms, Symptoms of heat rash include a small red papule on the skin. In severe cases, the area of the rash changes into a blister filled with a mysterious liquid, and an iris is formed around the skin. On the other hand, babies often develop diarrhea due to the use of diapers. These rashes are mainly caused by moisture or friction, and the main cause of the rash of the outermost stratum corneum is due to moisture. When a diaper rash occurs, the skin of the cold area of the diaper is reddish, and the skin becomes rough and severe, and it is accompanied by itching, and when it becomes worse, pus may occur.

In order to prevent the skin diseases of babies, conventionally, baby powder having talc as a main component is sprayed or applied to a body part where a rash and diaper rash are prone to occur. However, talc (talc), which is the main component of infant powder, contains asbestos, which poses a problem of its use. Because asbestos powder is drunk through the respiratory tract, lung cancer or lung cancer may develop through a long incubation period of 30 years or more, and malignant tumors may be induced in the pleura. For this reason, the International Agency for Research on Cancer (IARC) under the World Health Organization (WHO) has designated asbestos as a first-level carcinogen.

Due to the known risk of asbestos, recently baby powders without talc (talc) have been released. Starch has been proposed and used as a substitute for talc (starch). Starches used as food materials include sweet potato starch, potato starch, rice starch, sago starch and tapioca starch. Corn starch is mainly used. The baby powder containing such starch has a good feeling when used as compared with a baby powder mainly composed of talc (talc), but has a disadvantage in that the molded product is inferior in moldability and drop stability when it is formed into a compressed form.

Korean Patent No. KR 0010549 discloses an antimicrobial powder composition for infant which contains parabens and? -Bisabolol as main components to increase antiseptic power of infant powder in the prior art related to infant powder. However, the patent has a limitation in that it can not prevent the risk of asbestos because the content of talc (talc) is 82.68-92.22%. Patent No. KR 1049773 discloses an infant powder composition obtained by crushing and mixing golden (Skullcap), pine needle, ilite and clay with conventional techniques without using talc (talc). The above-mentioned prior art does not contain asbestos which is a carcinogenic substance and is harmless to the human body. In addition, when it is applied to a region where baby diaper rash or skin rash occurs, heat is lowered due to gold, moisture is well absorbed, The present invention relates to a powder composition for infants in which rash and erythema are treated by sterilizing action of pine needle and ilite. However, since the conventional art is a powdery composition, it is difficult to prove the characteristics of powderiness and product formability when it is prepared in the form of compressed powder.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The powder that was used conventionally to prevent the skin diseases of babies with weak skin was mainly composed of talc (talc) including asbestos which is carcinogen. Therefore, users have felt anxiety and danger in safety. To solve this problem, although the baby powder is prepared using starch, there is a drawback that the molded product and the dropping stability are not good when molded into a compressed form.

Accordingly, the present invention discloses a compressed powder cosmetic composition for infants which can be safely used on sensitive and fragile skin of infants using kaolin and starch harmless to human body, which are excellent in absorbing and absorbing ability, and capable of assuring moldability and drop stability. Particularly, according to the present invention, the corn starch and kaolin are pulverized by a high-pressure air stream, so that the physical properties of the product are not changed and the particle size becomes smaller and more uniform. As a result, the particle size distribution becomes narrower, And the stability is further improved.

The present invention provides a compressed powder cosmetic composition for children comprising corn starch and kaolin pulverized by high-pressure air flow.

The inventors of the present invention found that, in order to solve the safety problem by using starch and kaolin harmless to the human body instead of talc (talc), which was used as a main component of the conventional powder, and to produce a compressed powder cosmetic composition having excellent product formability and drop- Respectively. As a result, a compressed powder cosmetic composition comprising starch and kaolin pulverized by a high-pressure air stream having the above-mentioned merits was completed. The starch and kaolin particles can be made smaller and homogeneous by the high-pressure air stream pulverization treatment, And the pores between the powders are reduced. Thus, it has been confirmed that the moldability and drop stability of the final product are improved.

According to one aspect of the present invention, there is provided a compressed powdered cosmetic composition comprising a high-pressure air flow milled starch and kaolin.

The term " high-pressure air flow pulverization " in this specification refers to a method in which a substance to be pulverized together with compressed air is ejected at a high speed by ejecting steam air from a nozzle to discharge steam or water Condensing the air into the milling zone, it may mean that the material is pulverized by the high-pressure / high-speed air generated by the high-speed track movement of the internal jet nozzle (Jet Nozzle). Such high-pressure air flow pulverization has the advantage of obtaining a desired particle size by controlling the velocity and amount of generated air without changing the property of the pulverized product because there is no problem of heat generation in the general pulverizing equipment.

As used herein, the term starch is the same term as starch, meaning potato, sweet potato, rice, corn, dried ground powder that has been ground and mung called water.

In the present invention, the high-pressure air flow pulverized starch and kaolin particles and their particle sizes are very important. This is because, when the same amount of kaolin and starch which are not pulverized by high-pressure air streams are added, fine and uniform particles can not be formed, the hardness is low and the drop stability is unstable. However, This is because it shows the same hardness and drop stability as the products using talc (talc). Therefore, it is an important part of the present invention that fine and uniform particles can be formed by harmless to the human body by starch and kaolin subjected to pulverization treatment with a high-pressure air stream, and productivity can be improved.

Experimental Example

Experimental Example  1: high-pressure air flow corn starch and Kaolin  Particle size analysis

In order to investigate how the particle size of corn starch and kaolin changes through high pressure air flow milling, particle size before high pressure air flow milling and particle size after high pressure air flow milling were measured. Particle size was measured using a particle size analyzer (Mastersizer 2000, Malvern Korea).

(Unit: 占 퐉,? D = d _(0.9) -d _(0.1) ) before and after the pulverization treatment of the high- division Corn starch kaoline d _(0.1) d _(0.5) d _(0.9) Δd d _(0.1) d _(0.5) d _(0.9) Δd High-pressure air stream grinding
Before processing 8.71 13.95 22.16 13.45 1.15 3.73 10.87 9.72 High-pressure air stream grinding
After processing 7.96 11.13 16.92 8.96 1.00 2.80 6.29 5.29

As a result, the particle size of corn starch decreased about 20.0% for d _(0.5) , about 23.6% for d _{(0.9) and} about 33.3% for d ₍ d ₎ d _(0.5) was about 24.9%, d _(0.9) was about 42.0%, and Δd was about 45.5%. Here, d _(0.5) means the mean particle size, and Δd is the difference value between d _(0.9) and d _(0.1) , which means that the smaller the Δd value, the narrower the particle size distribution. Therefore, it was confirmed that the particle size of starch and kaolin became smaller and homogenized and the particle size distribution became narrower by pulverization treatment with high - pressure airflow.

Experimental Example  2: Hardness measurement test

(ASKER CL-150 Hardness Tester, TYPE) was used to investigate the difference in the hardness in comparison with Comparative Examples 1 and 2, in which a compressed powder product (example) containing infant corn starch and kaolin pulverized by a high- JAL, KOBUNSHI KEIKI CO. LTD) were used to measure the hardnesses of the Examples and Comparative Examples 1 and 2. The hardness was measured at four corners of the molded product and one at the center, and a total of five hardnesses were measured.

The hardness measurement results of Examples and Comparative Examples 1 and 2 division Example Comparative Example 1 Comparative Example 2 Hardness 44-53 31-39 42-51

As shown in Table 3, Comparative Example 1 using corn starch and kaolin, which had not been pulverized by high-pressure air currents, had a lower hardness formation than Comparative Example 2 using talc (talc). However, even though the same content of corn starch and kaolin was used, the hardness of the example using the raw materials pulverized by the high-pressure airflow was much higher than that of Comparative Example 1, which was similar to Comparative Example 2 using talc Or rather higher.

Therefore, it has been confirmed that the hardness is more easily formed when corn starch and kaolin are pulverized under a high-pressure air stream, and that the result is similar or even higher than the hardness of the product using talc (talc).

Experimental Example  3: Drop stability test ( Drop Test )

Following the hardness test, a drop stability test was conducted by testing whether the contents of the compressed powder product were affected by external impacts or cracking. The drop stability was obtained by averaging the number of drops of the compressed powder contents by 10 drops of the compressed powder contents after freezing the contents of the compressed powder into a container and then falling freely at a height of 70 cm on a 0.3 cm thick rubber plate. The mean values for each experimental group are shown in Table 4, and the average number of drops was found to be more stable as the number of drops was larger.

As a result of the drop stability test of Examples and Comparative Examples 1 and 2 division Example Comparative Example 1 Comparative Example 2 Average number of drops 5.9 4.1 5.5

As can be seen in Table 4, the drop stability test showed the same results as the hardness test. Compared to Comparative Example 2, Comparative Example 1 in which the high-pressure air stream was not pulverized had a smaller number of drops than the Comparative Example 2, but in the Examples using corn starch and kaolin pulverized by high-pressure airflow, the average number of drops was larger than Comparative Examples 1 and 2, It was judged to be the best.

Experimental Example  4: Evaluation of performance effect

30 infants aged 12-18 months with rashes, skin eruptions and diaper rashes were examined to see how the compressed powder product (example) for infants containing corn starch and kaolin, And the performance effect was evaluated. The children were assessed according to the criterion of the infant's parents after 30 days using the example, the comparative example 1 and the comparative example 2 for the site where the infant's skin disease occurred. The evaluation criteria were based on a 5-point evaluation (5: excellent, 4: excellent, 3: fair, 2: slightly, 1: no effect).

Evaluation of performance effect on infant skin disease division Example Comparative Example 1 Comparative Example 2 Sweat 3.82 3.20 2.96 Skin rash 3.59 3.19 2.85 Diaper rash 3.86 3.52 2.68 Side Effect 4.48 4.24 3.21

As a result of the performance effect, the performance using the corn starch and kaolin and the performance of Comparative Example 1 were superior to those of Comparative Example 2 using talc. In addition, the examples using corn starch and kaolin pulverized by high-pressure air flow were more excellent in performance than Comparative Example 1, which contained the same components but differed in pretreatment. This indicates that corn starch and kaolin were subjected to high- And thus the absorption capacity and absorption capacity were improved. As a result, it was judged that the performance effect was the best.
