The foundation emulsion of embodiment 2 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 balance of the foundation emulsion performance of embodiment 2 is different from the foundation emulsion of embodiment 1, but synthetically has good characteristic.
The foundation emulsion of embodiment 3 obtains that the R value of the transillumination relevant to transparent feel is high, covering power is more excellent and in sense evaluation, also can feel the evaluation of transparent feel.Know that the balance of the foundation emulsion performance of embodiment 3 is contrary with the foundation emulsion of embodiment 2, but synthetically there is good characteristic.
Know the foundation emulsion of embodiment 1 ~ 6 50 DEG C, 40 days heating through time before and after the amplitude of variation of viscosity be 100 [mPas] below, obtain the viscosity stability of 10 times compared with the foundation emulsion of comparative example 1 ~ 4.
Its result is thought, except containing as except the lauryl KF-6028 (HLB=3) of silicon-type nonionic surfactant, also containing the KF-6028 (HLB=4) as silicon-type nonionic surfactant in embodiment 1 ~ 4, also containing KF6017 (HLB=4) in embodiment 5, also containing poly-organosilicon 13 (HLB=3) in embodiment 6, demonstrate significant effect thus.In addition, the amplitude of variation of the viscosity of the foundation emulsion in embodiment 4 is 80 [mPas], becomes the result that viscosity stability is very excellent.
In addition, contain the foundation emulsion of the embodiment 7 of PEG19/PPG19/19 polydimethylsiloxane (HLB=2) as silicon-type nonionic surfactant, the amplitude of variation of viscosity of foundation emulsion of embodiment 8 containing PEG12 polydimethylsiloxane (HLB=6) is 500 [mPas], for the level that practicality is allowed, but be the vary within wide limits of embodiment 1 ~ 6 phase specific viscosity of 100 [mPas] with the amplitude of variation of viscosity.
According to above content aware, from the view point of viscosity stability, as silicon-type nonionic surfactant, and be the silicon-type nonionic surfactant C1 of 2≤HLB≤4 by HLB value, and structure is different from silicon-type nonionic surfactant C1, and the silicon-type nonionic surfactant C2 that HLB value is 2≤HLB≤6 is preferred, it is more preferred when the organic silicon modified by polyether of to be the organic silicon modified by polyether of 2 < HLB < 4 and HLB value by HLB value be 2 < HLB < 5 combines.
On the other hand, the foundation emulsion of the comparative example 1 and 3 ~ 4 that the use level of specific Titanium particles is many due to compared with the foundation emulsion of embodiment 1 ~ 3 covering power too high, so the R value step-down of transillumination, transparent feel is poor.
Employ and in resin bead (PMMA: polymethyl methacrylate), mechanically to squeeze into red No. 202 microgranules and the foundation emulsion of the comparative example 4 of red pigment-PMMA composite granule that makes produces apparent uneven redness because oozing out in transparent glass container.
The irregular colour covering power of the foundation emulsion of the comparative example 5 not containing specific Titanium particles is too low, cannot allow as foundation emulsion.
