2nd, whitening, highlight experiment
Study subject and method
1.1 study subject
1.1.1 the inclusion criteria of subject:1. the normal men and women subject of age 18-60 year, women are preferential;2. without serious system
System property disease, no immune deficiency or autoimmune disease person;3. no active anaphylactia person;4. previously to skin type
Cosmetic is without allergies;5. whole body does not use hormone medicine and immunodepressant person in nearly January;6. it is clinical not participate in other
Experimenter;7. volunteer, which participates in and can press test requirements document, completes specified content person.
1.1.2 exclusion condition:1. gestation mends newborn phase women;2. based on outside work, Exposure to Sunlight person can not be avoided;3. test
Period causes Exposure to Sunlight enhancer because of a variety of causes (such as travel, spend a holiday);4. trial employment period whole body application steroids, immune formulation class
Medicine person;5. trial employment period face applies anti-inflammatory drug person;6. the infull person of tested material or data is not used according to regulations.
1.1.3 number of subjects:54 people (meet cosmetics moistening effect evaluation guide and whitening class cosmetic industry are assessed
Subject's quantity (more than 30 people) of guide for method principle defined).
1.2 method
1.2.1 the preparation of given the test agent:In order to avoid sample in set-up procedure by microorganism pollution, it is direct with facial mask
The scissors of contact, packaging bag etc. sterilize before use, and the personnel for preparing sample wear gloves operation.
1.2.2 facial test position:Facial forehead, chin, left cheek, right cheek are as pilot region.
1.2.3 facial method of testing:White-skinned face function product (cosmetics, topical drug can not be used before face test within 2-3 days
Or health products for oral administration).Before experiment, subject needs unified cleaning skin of face, with dry face tissue wiped clean.Allow subject
Sit quietly at least 30min in standard compliant room, skin of face exposure, it is impossible to rub, keep loosening.
1.2.4 testing time-effectiveness:Periodicity efficacy assessment, 3 times a week, follow-on test 12 weeks.
1.2.5 evaluation:Facial mask trial effect is evaluated by the way of questionnaire, and wherein moisture retention is surveyed by skin moisture
Examination instrument is evaluated, and outward appearance and whitening highlight effect and pass through subject's sensory evaluation
The facial mask sense organ evaluating meter of table 3
1.3 experimental result
Sensory testing is carried out to 54 Eligible subjects, there are 4 people halfway because different reasons exit, it is final to obtain complete test
As a result 50 parts, test result is divided into typically, satisfied and very satisfied Three Estate, the number of each grade under each test item is entered
Row statistics, obtains corresponding test result, whole test result is as shown in the table:
The facial mask Analyses Methods for Sensory Evaluation Results table of 4 prescription of table 1
The facial mask Analyses Methods for Sensory Evaluation Results table of 5 prescription of table 2
The facial mask Analyses Methods for Sensory Evaluation Results table of 6 prescription of table 3
The facial mask Analyses Methods for Sensory Evaluation Results table of 7 prescription of table 4
3rd, the facial mask moisture retention test that skin moisture teller measures
2.1 laboratory apparatus
Bioelectrical impedance analysis (BIA) technology, digital skin tester
2.2 principle
Skin moisture content is determined by inside and outside two kinds of factors, keratoderma keep moisture content capacity variation compared with
Greatly, water content can be from 10% to 60% change, most important or skin perspiration respiratory and the mixing of skin reclaimed water
The composition of thing.External factor includes environment temperature, humidity, medicine and cosmetics etc., can determine and change the moisture content in skin
Content.Skin moisture content can influence the water of skin surface and the formation of grease hybrid films, and this layer of diaphragm declines to skin
It is always very important.Therefore the test skin moisture content of quantification and the variable quantity after relatively certain nursing stage are that have very much
.
2.3 experimental method
Strong effect product (cosmetics, topical drug or health products for oral administration) can not be used before face test within 2-3 days.Experiment
Before, subject needs unified cleaning skin of face, with dry face tissue wiped clean.Subject is allowed in standard compliant room
Sit quietly at least 30min, skin of face exposure, it is impossible to rub, keep loosening.With skin moisture teller measure skin forehead and
The moisture of cheek, reading simultaneously record tested preceding moisture of skin.
Remove, patted to absorption after face mask film 15min.Without using any facial products in 12 hours, exist respectively
10min, 30min, 60min, 12h, rear test, and record tested rear moisture of skin.
Using increasing value method (increasing value=tested rear moisture of skin-tested preceding moisture of skin) is averaging, obtain using production
The moisture increasing value of facial skin after product.
2.4 experimental result
The prescription 1 of table 8
The prescription 2 of table 9
The prescription 3 of table 10
The prescription 4 of table 11
4th, tyrosinase inhibitory activity is tested
Experimental method (with reference to " Wei Zhen holds Guangzhou Food Industry science and technology .Vol.20No.3, P10-11 "):Take prescription 1,2,
3rd, 4, the 5 Essence 10ml prepared.With phosphate buffer (pH=6.8) sample dissolution, every kind of sample is each configured into concentration is
1mg/ml sample is to be measured.
2ml (blank group is with phosphate buffer replacement) is respectively taken to add tyrosinase (100U) in each test group, at 37 DEG C
10min is heated in Water Tank with Temp.-controlled, 0.003mol/L dopa reaction liquid 1ml is added, is sufficiently stirred, it is anti-in 37 DEG C (waters bath with thermostatic control)
After answering 2min, take out immediately, determine the absorbance at 475nm.
Inhibiting rate={ [(A-B)-(C-D)]/(A-B) } * 100%
A adds the absorbance that the mixed liquor of tyrosinase measures at 475nm for the product of not being loaded;B is not to be loaded product and do not add
The absorbance that the mixed liquor of tyrosinase measures at 475nm;C surveys for the mixed liquor of sample-adding product and tyrosinase at 475nm
The absorbance obtained;D does not add the absorbance that the mixed liquor of tyrosinase measures at 475nm for sample-adding product.
Inhibiting rate of the table 12 to tyrosinase
Test result indicates that:The solution of prescription 4 is best to the inhibition of tyrosinase, inhibiting rate 39%, hence it is evident that be better than
Other each groups, this also indicates that the whitening function of prescription 4 is better than other each groups.
Conclusion:
Although the herb extract total content contained in prescription 1~4 it can be seen from above-mentioned three kinds experiments is identical, so
And after four kinds of radix glycyrrhizae, green tea, olive leaf and giant knotweed herb extracts are applied in combination, whitening highlights notable with the effect such as moisturizing
Better than alone one of which extract (such as prescription 1) and two-by-two compatibility (such as prescription 2) and three kinds of extract compatibility (such as prescriptions
3), this is indicated that, after four kinds of herb extracts are applied in combination the present invention, synergistic function has been played, to human skin
Whitening highlights to be significantly improved with moisturizing activity, and four kinds of extracts are indispensable.
