Description

Underwater type composition

The present invention relates to the improvement of an underwater type composition using an oil-in-water type composition, particularly a water-absorbing hydrophobic powder.

In general, the skin care and cosmetic operations are carried out by arranging the condition of the skin by skin care cosmetics such as lotion and then correcting defects (hue or unevenness) of the skin by foundation, and further, Shadows are given, and appearance is arranged.

Powdery foundation, liquid foundation and the like exist as the foundation, and in particular, the liquid foundation is excellent in good spreading and the demand is also expanding.

However, since the liquid foundation uses a liquid oily base regardless of the oily or emulsified system, tackiness tends to occur after application, and it is difficult to obtain smooth skin feeling of powdery foundation by this point.

2 is an explanatory diagram of a state in which an aqueous medium is blown by a powder.

Hereinafter, embodiments of the present invention will be described in detail.

[Absorbent Minor Powder]

As the oil absorbing hydrophobic powder preferably used in the present invention, crosslinked polymethyl methacrylate, nylon porous powder and the like are preferably used. The material itself may be lipophilic, or the material may be hydrophilic but may be coated with an oleophilic material, but in the case of coating, it is preferably lipophilic to the inside of the hole.

The maximum oil absorbable amount of the oil absorbing hydrophobic powder is preferably 90% by mass or more based on the powder. If the maximum oil absorbable amount is less than 90% by mass, sufficient oil can not be absorbed at the time of application, and good skin feel may not be obtained.

First, the inventors of the present invention conducted the tests shown in the following Table 1, and gave a liquid feeling foundation a smooth feeling of Powdery Foundation without deteriorating the feeling of application such as spreading.

As shown in Table 1, when the resin powder was not blended (Test Example 1-1), a feeling of feeling that was smoothly conveyed was not obtained, and it was difficult to formulate the composition unless a so-called surfactant was used. In addition, in the case of using the crosslinked polymethyl methacrylate porous powder, the dispersibility of the powder was poor and the formulation was difficult (Test Example 1-2) unless ethyl alcohol was added.

On the other hand, when the cross-linked polymethylmethacrylate porous powder is added to the dispersion medium in which the ion-exchanged water and ethyl alcohol are mixed, a good powder dispersion is formed and the porous powder hardly floats, It was found that the medium was being blown, and furthermore, by observing for about 10 seconds on the skin while maintaining good spreading from the oil, it was found that stickiness due to oiliness was lost and a feeling of smooth and smooth feeling was obtained (Test Example 1 -3). In this regard, the inventors observed the drying process of the composition. The results are shown in Fig. That is, 0.01 g of the product was placed on a slide glass, spread on a toothpick and dispersed, and the drying process was observed with a microscope at a magnification of 40 without raising the cover glass. Immediately after the picture on the left side, 30 seconds after the middle picture is applied, and the picture on the right side shows after 1 minute. As shown in Fig. 1, it was confirmed that, in the composition (immediately after application), the solvent existing to surround the crosslinked polymethacrylate porous powder disappeared upon drying.

In addition, the inventors of the present invention have examined the oil-absorbing function on the skin characteristic of the present invention. 1. A mixture of 80% of water, 10% of ethanol and 10% of crosslinked polymethylmethacrylate porous powder and 2. a mixture of 90% of water and 10% of crosslinked polymethylmethacrylate porous powder were prepared, And the mixture was stirred with a disper at a speed of 2000 rpm for 1 minute to prepare a sample. Fig. 2 is a photograph of a sample immediately after the preparation and after being allowed to stand for one day.

Immediately after the stirring and adjustment, all of the two samples were completely white, and neither of them seemed to remain unchanged. However, when the mixture was allowed to stand for one day, the upper part of 1. was transparent and the crosslinked polymethylmethacrylate porous powder was almost settled. This suggests that the water-soluble component composed of water / EtOH was taken into the pores of the crosslinked polymethylmethacrylate porous powder and precipitated because the specific gravity became heavy.

On the other hand, if only the water of Section 2 is used, part of the porous powder is settled, but most of it floats on the water surface.

The crosslinked polymethylmethacrylate is a hydrophobic powder. When the dispersion medium is composed only of water, the absorption amount of the dispersion medium (water) is considered to be very small. On the other hand, in the aqueous medium in which organic solvents are mixed, It is understood that the acrylate absorbs the dispersion medium (aqueous medium).

Next, the present inventors conducted studies on a dispersion medium (aqueous medium) of powders. The results are shown in Table 2.

As shown in Table 2, both of ethyl alcohol and isopropyl alcohol showed almost the same tendency. When the amount of the volatile organic solvent in the aqueous medium was 5 mass% or more, formulation suitability and a good feeling of use were obtained. When the amount is less than 5% by mass, the dispersibility and the water absorbability for the oil-absorbing hydrophobic powder may not be sufficiently secured. In addition, it was possible to obtain a preferable range such as 7 to 10 seconds (time for changing the feeling of touch) that changes from a good oiliness to a feeling of smoothness that originally started application, Further, according to the study by the inventors of the present invention, it has been found that when the change time of the touch change is less than 5 seconds, it may be difficult to slightly coat, and when it exceeds 20 seconds, it is often not judged to be a smooth application.

In order to obtain the effect of the present invention, the upper limit of the amount of the organic solvent to be added is not particularly limited. However, considering the fact that it is used in a foundation or the like, the amount of the organic solvent in the aqueous medium is preferably about 30% by mass.

In addition, the present inventors have conducted studies on various oil absorbing powders. The results are shown in Table 3.

From the results shown in Table 3, it can be seen that sufficient oil absorption can not be obtained when the oil absorption amount is less than 90% by mass based on the powder (Test Example 3-1) even in the case of a small amount of powder, and in the case of hydrophilic silica, (Test Example 3-2).

On the other hand, the hydrophobic powder having an oil absorption of 90% by mass or more was able to obtain an improvement in feeling of use, regardless of whether or not the powder was porous (Test Examples 3-3 to 3-7).

In addition, the inventors of the present invention have examined the blending amount of the oil-absorbing hydrophobic powder. The results are shown in Table 4.

It is understood from Table 4 that the compounding amount of the oil-absorbing hydrophobic powder in the composition is 5 to 25% by mass, particularly preferably 10 to 20% by mass.

In addition, the present inventors have studied the oil. The results are shown in Table 5.

As apparent from Table 5, the effect of the present invention can be exhibited irrespective of oil species, but an ester oil having a relatively low viscosity (100 mPa · s or less) is preferably used, and the viscosity of the silicone oil and the hydrocarbon oil is increased It became a souffle shape.

Further, the inventors of the present invention paid attention to the relationship between the oil absorbable amount and the oil content of the oil-absorbing hydrophobic powder. The results are shown in Table 6.

From Table 6, an extremely good feel is obtained when the oil content is 80% or less of the oil-absorbable amount, but an improvement effect of feeling can be exhibited up to about 130%. However, if it is more than 150%, the change time of the touch change becomes longer, and it becomes difficult to realize a feel that is smoothly conveyed.

In addition, the inventors of the present invention have examined the improvement of powder sedimentation in the preparation. In other words, the powder precipitates in the formulation and the powder can not be redispersed in the solvent in some cases. Thus, as a result of studying the sedimentation improvement, as shown in Table 7, sedimentation improving effect was observed in xanthan gum, and the blending amount of xanthan gum was preferably about 0.03 to 0.5 mass% in consideration of viscosity increase.

The evaluation was evaluated as " Good " when the sedimentation of the powder was hardly observed in the solvent and " Good " when the sedimentation was observed in the sample stored at 50 캜 for 4 weeks.
