Summary of the invention
Invent problem to be solved
But, foundation cream disclosed in Japanese Unexamined Patent Publication 8-239310 publication and Japanese Unexamined Patent Publication 2002-265332 publication just mixes simply with organo-metallic compound etc. due to the pigment as color material in foundation cream base, so when applying the wet type method of forming in the molding of foundation cream, pigment stripping sometimes (oozing out) is in solvent.Consequently, sometimes in foundation cream, produce irregular colour and damage outward appearance, or producing painted when foundation cream is imparted on skin.
In addition, foundation cream disclosed in Japanese Unexamined Patent Publication 2002-265332 publication due to use blue pigment as color material, so be difficult to obtain transparent feel because of the reduction of red transmission light quantity.
Although the resistance to stripping property of opaque foundation cream disclosed in Japanese Unexamined Patent Publication 2012-184211 publication is excellent, be not conceived to transparent feel and covering power, sufficient transparent feel and sufficient covering power can not be obtained.
Disclosed in Japanese Unexamined Patent Publication 11-12493 publication and Japanese Unexamined Patent Publication 11-35840 publication, opaque foundation cream is because the titanium oxide using 10 quality % a large amount of is like this as inorganic particle, so be sometimes difficult to obtain transparent feel because of the reduction of red transmission light quantity.

Table 3
As shown in table 3 and Fig. 1, the opaque foundation cream of embodiment 1 and embodiment 3 obtains high, that transparent feel is also high in sense the is evaluated evaluation of R value of the transillumination relevant to transparent feel.And then know, the opaque foundation cream of embodiment 1 and embodiment 3 is very difficult to produce de-adornment, synthetically has good characteristic.
The opaque foundation cream of embodiment 2 obtains high, that transparent feel is also high in sense the is evaluated evaluation of R value of transillumination.And then know, the covering power of the opaque foundation cream of embodiment 2 is very excellent, and the balance of performance is different from the opaque foundation cream of embodiment 1 and embodiment 3, but synthetically has good characteristic.
On the other hand, opaque foundation cream covering power compared with the opaque foundation cream of embodiment 1 ~ 3 of the comparative example 1 that the use level of pigment-level Titanium particles is many is too high, so the R value step-down of transillumination, transparent feel is poor.
The opaque foundation cream of the comparative example 4 of the red pigment-PMMA composite granule made containing mechanically squeezing into red No. 202 microgranules in resin bead (PMMA: polymethyl methacrylate) produces the uneven redness on cake surface because oozing out.
Transparent feel is low on the whole for comparative example 2 not containing specific red composite granule and containing red iron oxide and the opaque foundation cream of comparative example 3, and performance is obviously poor compared with the opaque foundation cream of embodiment 1 ~ 3.
The covering power of the opaque foundation cream of the comparative example 5 not containing pigment-level Titanium particles is too low, cannot allow as opaque foundation cream.
The opaque foundation cream of comparative example 6 is due to containing blue pigment, so blue pigment dominant absorption red light, thus red transmission light quantity significantly reduces, and transparent feel worsens.
The opaque foundation cream of comparative example 7 ~ 9 owing to also having coordinated Large stone Titanium particles except pigment-level Titanium particles, so red transmission light quantity, covering power all worsen, poorer than the opaque foundation cream of embodiment 1 ~ 3.
