Data as shown in Table 16 as it can be seen that compared with comparison application examples 1, comparison application examples 2-7 and comparison application examples 8-13,
The lotion of application examples 1-4 by addition peptide composition, compared to addition single polypeptide ingredient, any five kinds of peptide compositions or
Polypeptide moiety is not added, the moistening effect of skin is obviously improved, shows as the water that can effectively increase keratoderma
Divide content, reduces the external water loss of skin.
It can be seen that peptide composition of the invention be applied to the moistening effect in cosmetics than addition single polypeptide at
Point, any five kinds of peptide compositions or not add the moistening effect that polypeptide moiety is applied in cosmetics much better.
Comparative example 13-18 is to replace it using the polypeptide with similar maintenance respectively on the basis of embodiment 1
A kind of middle obtained peptide composition of polypeptide, such as comparative example 13 are using the same palm for having and promoting cell growth function
Acyl hexapeptide -6 replaces the oligopeptides -1 in embodiment 1.And comparative example 14-19 is the polypeptide for adding comparative example 13-18 respectively
The maintenance lotion being prepared after composition.It can be seen that the flesh using comparison application examples 14-19 lotion from the data in table 16
Skin moisture content is significantly lower than application examples 1-4, this shows that six kinds of polypeptide fractions of the invention are irreplaceable, indispensable, and six kinds
Between polypeptide fractions exist synergy, also from illustrate on the other hand peptide composition of the present invention have common maintenance skin screen
Barrier improves skin water lock, moisture-keeping functions, restores skin health, water moistens state.
2, it is tested using the anti-oxidation efficacy of method 2, as a result as shown in table 17 below:
The evaluation of 17 anti-oxidation efficacy test result of table
As it can be seen that multiple-effect maintenance peptide composition of the invention reaches as high as superoxide anion clearance rate from table 17
69.3%, 65.2% is reached as high as to Scavenging action to hydroxyl free radical, elimination effect is significantly larger than single polypeptide and containing any more than five kinds
Peptide combinations are to the clearance rates of two kinds of free radicals, while compared with comparative example 13-18, and embodiment 1-4 is to superoxide anion and hydroxyl
The clearance rate of free radical also significantly improves, this illustrate it is indispensable between six kinds of polypeptide fractions, it is synergistic, make polypeptides in combination
Object has preferable antioxidant effect.
3, it is tested using the sensitive effect of stimulation of releiving of method 3, as a result as shown in table 18 below:
Table 18 is releived the evaluation of sensitive effect of stimulation
It can be seen from the data in table 18 compared with comparing application examples 1, application examples 1-6's contains multiple-effect maintenance polypeptide
The maintenance lotion of composition has good maintenance effect to skin, can soothe the skin susceptibility, reduces lactic acid effect of stimulation, and
And there is good moistening effect, hence it is evident that increase keratoderma moisture content, reduce the external water loss of skin.And from
Application examples 14-19 data are compared it can also be seen that replacing any one in six kinds of polypeptide fractions, the moistening effect of lotion
It is decreased obviously with the ability for sensitive stimulation of releiving.It, can there are coordinated effect between this six kinds of polypeptide fractions of explanation
It is common to repair skin barrier, promote the effect of the moisturizing water lock of skin and sensitive stimulation of releiving.
4, using the normal individual trial evaluation test of method 4, as a result as shown in table 19 below:
19 normal individual trial evaluation result of table
By 19 data of table as it can be seen that the result of half face test evaluation of human body significantly contrasts this example sample and blank sample
Effect difference.It compares application examples 1-6 and compares the data of application examples 1, it can be clearly seen that the cream containing peptide composition of the present invention
Liquid is obvious to the improvement of glossiness, compact degree, anti-wrinkle effect and light spot effect, in addition, also having in terms of moisturizing good
Performance can allow the low and deep skin of relaxation to be got well state, and water Rinsing is sliding, and compact full, shining light is adopted.
The Applicant declares that the foregoing is merely a specific embodiment of the invention, but protection scope of the present invention not office
It is limited to this, it should be clear to those skilled in the art, any to belong to those skilled in the art and take off in the present invention
In the technical scope of dew, any changes or substitutions that can be easily thought of, and all of which fall within the scope of protection and disclosure of the present invention.
