Blank control is separately used as using the toner of table 5.The preparation method of blank control toner used and the radiation proof of preparation Negative control preparation method in efficacy assessments is identical.
Test before through the trained health volunteer 30 of professional (each 15 of men and women), the age at 20~30 years old, institute Have subject without skin or systemic disease history, recipient site is without exception, and tested period do not smear it is any unrelated with experiment Medicine or cosmetics.
Test site room temperature (25 ± 1) DEG C, relative humidity (40 ± 5) %, subject should keep body as stabilization before test State.After wiping subject's both arms using 35 DEG C or so of clear water, start to test after the 30min that sits quietly under test environment.
At subject's inboard arm is away from palm base portion 5cm, tested region (4cm × 4cm) is marked, same arm can be simultaneously Mark multiple regions (interval 1cm), the equal random distribution of test sample.The blank value of each test zone is first measured, then test specimens By (2.0 ± 0.1) mg/cm2Dosage carry out single application, Multi-functional skin moisture tester and moisture of skin are used after coating Lost instrument measures the moisture loss value in the tested region of 1h, 2h and 4h and blank control region respectively.
Subject is smeared 5 data measured in same sample region and averaged by test, using SPSS statistical softwares Carry out t check analyses.
Experimental result
Moisture of skin, which scatters and disappears, to be changed
Moisture of skin windage (Transepidermal water loss, TEWL) is reflected in test period, test block Domain moisture loss changes with time rule, and it can be with the skin barrier maintenance function of characterization test sample, its smaller, moisture of value Scatter and disappear fewer, skin repair ability is stronger;Conversely, skin repair ability is weaker.
Percentage of water loss (%)=(sample sets water loss amount-starting moisture windage)/starting moisture windage × 100
As a result show:In 4h, embodiment 4,5,6,7 has skin repair ability effect.
