In order to the glossiness assessing NLK-602 reduces effect, SAMBA (Bossa Nova Technologies) is used to take the photo of the whole face of male's experimental subject, and by using the SAMBA photograph image process of SHIVA software, each individuality is determined to the glossiness mark (T of bare skin 0).Then experimental subject is divided into two groups, is administered to reference to example on the face of a group, and embodiment 1 is administered on the face of another group.The amount being administered to each experimental subject face is for half of face 2ml embodiment, and this amount is used for all embodiments (comprising following embodiment 2,3 and 4).Retain said composition 30 minutes.(T at the end of the time period of 30 minutes 30) again determine glossiness mark.By T 30time mark be converted into relative to T 0time (T 0be 100.0%) percentage rate of each mark.Student t inspection (student's t test) is used to compare these results, to determine T 0and T 30glossiness mark between whether there is any significant difference.
(sebum fraction measurement)
In order to determine that the sebum of NLK-602 reduces effect, sebum meter (Courage-Khazaka) is first used to determine the bare skin sebum mark (T of the forehead of at least six male's experimental subjecies 0).Then experimental subject is divided into two groups, is administered to reference to example on the forehead of a group, and embodiment 1 is administered on the forehead of another group.Retain said composition 30 minutes.(T at the end of the time period of 30 minutes 30) again determine sebum mark.By T 30time mark be converted into relative to T 0time (T0 is 100.0%) the percentage rate of each mark.Student t inspection is used to compare these results, to determine T 0and T 30sebum mark between whether there is any significant difference.
The result of glossiness and sebum fraction measurement is summed up in FIG, and clearly illustrates that, by using the embodiment 1 containing NLK-602, glossiness mark and sebum mark reduce all significantly.In contrast, by using reference example, glossiness and sebum mark all significantly do not reduce.
(Valid concentration of NLK-602)
Embodiment 2,3 and 4
Then, in the whole concentration range of NLK-602, assess NLK-602 glossiness and sebum reduce effect.Embodiment 2,3 and 4 is prepared according to table 2.
Table 2
Measure T in the above described manner 0and T 30time glossiness mark and sebum mark.Result is summarised in Fig. 2 A and B respectively, and along with the rising of NLK-602 concentration, shows the reduction of the glossiness mark depending on dosage.Although the NLK-602 of 1 % by weight does not produce significant change, the NLK-602 of 2 % by weight and 5 % by weight significantly reduces glossiness mark.On the other hand, all three kinds of concentration of NLK-602 significantly reduce sebum mark.
(maximum pore size measurement)
Except glossiness and sebum mark, assessment embodiment 2,3 and 4 is for the impact of maximum pore size.Before applying said compositions, Dermascore (the original-pack equipment of L'Oreal) is used to take the photo of male's experimental subject two cheek, and by these photos of Dermapore software image process, to determine that each individuality is at T 0time maximum pore size (bare skin).Experimental subject is divided into three groups, and embodiment 2,3 and 4 is applied on the cheek of the experimental subject of each group.Retain said composition 30 minutes, and at the end of the time period of 30 minutes (T 30) again determine maximum pore size.By T 30time maximum pore size be expressed as relative to T 0time (T 0be 100.0%) the percentage rate of each pore size.Student t inspection is used to compare these results, to determine T 0and T 30maximum pore size between whether there is any significant difference.Maximum pore size measurement result is summarized in Fig. 2 C.As can be seen from Fig. 2 C, embodiment 2 and 3 all causes the remarkable reduction of maximum pore size, and embodiment 4 also shows the reduction of maximum pore size, although it is inapparent.
(comprising low-polarity component)
Although above embodiment is only containing hydrophilic composition, the present invention is not limited to this.According to table 3, prepare embodiment 5 with low-polarity component polydimethylsiloxane, and itself and embodiment 2 are made comparisons with regard to its matte effect.Measurement dumb light mark as described below.
Table 3
(dumb light fraction measurement)
Embodiment 2 and 5 is administered to contrast printing paper (contrast paper) (Erichsen; Type 24/5) on sheet, respectively form the layer of 50 microns thereon.Retain these samples 20 minutes, 2 hours and 6 hours, and measure specular light and the intensity that diffuses at each time point by goniophotometer (Murakami).Use BaSO 4layer, as the matt surface of standard, uses following formula to set desirable dumb light value.
Direct reflection intensity (BaSO 4)/Diffusive intensity (BaSO 4)=100%
Then the value using embodiment 2 and 5 to obtain and desirable dumb light value are made comparisons, to determine whether the existence of low-polarity component affects the matte effect of the compositions containing NLK-602.These results are summed up in figure 3.As can be seen from Figure 3, embodiment 2 and 5 shows the similar trend of its dumb light mark aspect across these time points, and this shows to comprise low-polarity component, and does not damage desired matte effect.
Set forth the present invention with reference to above embodiment.As can be seen from experimental result, compared to reference example, the waterborne compositions of these embodiments shows obviously better matte effect and pore and minimizes effect.These embodiments are only the examples of concrete probability, and those skilled in the art will recognize that various modification is feasible, and such modification is also contained in the present invention.
