△ tests the moisture-retaining capacity of this product with MMV；
Test method is as follows：
Test philosophy：
For the method using the moisture content of capacitance measurement human skin keratinocyte layer, principle is based on water and other substances
Difference in dielectric constant it is significant, according to the difference of moisture content of skin, the capacitance of the skin measured is different, and observed parameter can generation
Table skin moisture value.
Experiment condition and volunteer require：
Test environment conditions：Testing environment temperature is 22 DEG C ± 1 DEG C, and humidity is 50% ± 5%, and carries out dynamic in real time
Monitoring.
Volunteer requires：Effective volunteer at least 30 people；Age is between 16 years old~65 years old；Forearm test zone capacitance method
The basic value of moisture of skin analyzer is between 15 years old~45；Without serious systemic disease, without immune deficiency or autoimmune disease
Patient；No active anaphylactia person；
Previously to skin-care cosmetics without severe allergy history person；Not using hormone medicine and immune suppression in nearly 1 month
Preparation person；Other clinical test persons are not participated in；Use according to regulations tested material and all information；All volunteers should fill in front of testing
Informed consent form.
Any product (cosmetics or topical drug) cannot be used within 2 days~3 days before recipient site.Before test, subject is needed
It cleans in both hands forearm and surveys, with dry face tissue wiped clean.After cleaning, is surveyed in subject's both hands forearm and carry out measurement zone
Field mark.Before official testing, it should which sit quietly at least 30min in standard compliant room, cannot drink water, forearm exposure, in survey
Examination state is placed, and keeps loosening.
Testing procedure：
In experiment, 3cm × 3cm test area is marked on the inside of left and right arm, same arm can mark multiple regions, area simultaneously
Domain interval 1cm.Test product and blank control are randomly dispersed in left and right arm.Using capacitance method skin analyzer carry out by
Sample 1-5, is spread evenly across in trial zone by the measurement for trying region and control zone using latex finger cot.After smearing, survey respectively
When measuring 1h, 2h and 4h, the moisture content of skin MMV value in tested region and blank control region.
| MMV value/1h | MMV value/2h | MMV value/4h | |
| Sample 1 | 42 | 36 | 25 |
| Sample 2 | 49 | 38 | 30 |
| Sample 3 | 55 | 41 | 37 |
| Sample 4 | 50 | 37 | 30 |
| Sample 5 | 36 | 29 | 21 |
| Blank control | 26 | 25 | 27 |
By testing the formula it can be seen that sample 3 above：5g white tea leaf extract, 5g butanediol, 3g biology carbohydrate gum -4,
0.5g Sodium Hyaluronate, 0.5g hydrolyze Sodium Hyaluronate, 0.8 additive, 2 theanine, 2 tea polyphenols.Additive is according to mass parts
Number is mixed to optimization formula than decoyl hydroximic acid 25%, 1,2- hexylene glycol 45%, 1,3- propylene glycol 30%.The present invention uses
White tea compares green tea, black tea, amino acid, theanine, flavones, caffeine, soluble polysaccharide content as raw material, white tea is extracted
Height, especially amino acid content are high；The cooperation of white tea leaf extract and moisturizer, amino acid, hyaluronic acid, soluble polysaccharide mention
For the enough nutrition of human skin, flavones and caffeine adjust texture.
By the comparison of the experimental result of sample 5 and other samples it is found that the extracting method of white tea has obviously moistening effect
It influences.The present invention extracts white tea leaf extract by breaking-wall cell separation and the method for low-temperature extraction, improves in white tea effectively
The utilization rate of ingredient；It is not necessarily to preservative in extraction process, improves the safety of product, sensibility skin is suitble to use.
△ tests the whitening capability of detection this product with Lab colorimetric analysis；
Using sample 1-5 above as product,
Laboratory apparatus：Mono- 400 color instrument of Chromameter CR, Konica Minolta Sensing.Inc., Japanese.
Test environment conditions：In the test environment of constant temperature and humidity, kept for 22 ± 1 DEG C of temperature, humidity 50 ± 5%.
Volunteer's number：Select qualified volunteer 24.
Test position：At the left and right forearm crook of the arm of volunteer.
Test period：8 weeks/each product.
Color instrument L value, a value, the colorimetric analysis test process of b value are as follows：
Instruct volunteer by prescribed requirement using product 8 weeks, with the L of color instrument parallel testing volunteer's left and right arms crook,
A, the initial value of b, intermediate value (at 4 weeks) and end value are each 6 times (at 8 weeks), and to the skin color parameter L value measured, a value, b value is carried out
Statistical analysis compares, and the white-skinned face function of testing product is evaluated by statistical result.
As a result it statisticallys analyze：
Using 7.1 statistical software of Statistica (Statsoft Company, the U.S.), to the skin of all volunteers
Being described property of color parameter statistics；
The L numerical value that color instrument measures represents skin Black-White, and variation indicates skin black and white before and after whitening product use
The variation of degree, numerical value is bigger, and expression skin is brighter.A represents red green degree, and skin is red before and after variation indicates whitening product use
The variation of greenness, the bigger skin color of numerical value are more partial to red.B represents blue yellow chromaticity, and variation indicates that whitening product makes
With the variation of front and back skin indigo plant yellow chromaticity, the bigger skin color of numerical value is more partial to yellow.
ITA is calculated by the Lab value measured, ITA is to be become clear as defined in Colipa by the calculated characterization skin of above formula
The numerical value of degree, ITA.Value is bigger, and skin is brighter, conversely, skin is darker and more gloomy.
L value, a value, b value, the intermediate value of ITA value are summarized as follows compared with the difference of initial value and last value and the difference of initial value：
"+", indicates：Significant difference, p≤O.05；"-", indicates：There is no significant difference.
By testing the formula it can be seen that sample 3 above：5g white tea leaf extract, 5g butanediol, 3g biology carbohydrate gum -4,
0.5g Sodium Hyaluronate, 0.5g hydrolyze Sodium Hyaluronate, 0.8 additive, 2 theanine, 2 tea polyphenols.Additive is according to mass parts
Number is mixed to optimization formula than decoyl hydroximic acid 25%, 1,2- hexylene glycol 45%, 1,3- propylene glycol 30%.
