Evening is each primary.Respectively statistics is primary after 1 week, 4 weeks.
2, curative effect determinate standard
(1) it cures:Clinical symptoms disappear, condition susceptible subsides;
(2) effectively:Clinical symptom relief, condition susceptible subside or disappear, and reduce or reduce;
(3) invalid:Clinical symptoms, condition susceptible do not improve.
Clinical observation result and conclusion
1, result
Embodiment 4-6 and comparative example 1-7 has effects that the total situation of cream clinical observation and subject's disease that antiallergic is releived
The case where shape performance and curative effect, refers to table 7.
7 embodiment 4-6 of table has effects that the total situation of cream clinical observation that antiallergic is releived
2, clinical effectiveness is analyzed
(1) it is directed to skin of face sensitive group, skin of face cardinal symptom (itches, erythema, dry furfur situation, uses reality
Cream that a 4-6 has effects that antiallergic is releived is applied 1 week to efficient up to 90% (45), and 1 month cure rate is 72%
(36).
(2) it is learnt by embodiment 4-6 and comparative example 1-7 comparisons, it is Japan cypress, white willow, hundred golden flower, rheum rhabarbarum, Chuan Gu, big
When any of several broadleaf plants, rhodiola root only share, it is just notable to treat sensitive skin effect.
(3) trier has effects that Application Example 4-6 the overall assessment after cream that antiallergic is releived 4 weeks is shown in Table 8:
Table 8
(4) as long as adhering to that use is notable to sensitive skin crowd therapeutic effect.
Prepared by ten, embodiments 4-6 has effects that the cream white-skinned face function experiment that antiallergic is releived
1. experimental principle
Human experimentation forms test population by particular experiment crowd, and test subject uses cosmetics (and cosmetics work(
Imitate ingredient) before and after skin color variation, so that it is determined that the white-skinned face function of cosmetics (or functional component).
2. laboratory apparatus and sample
Instrument:Dermal melanin and ferroheme tester (Mexameter MX18, German CK electronics corporations production);Lab
Color difference meter (MPA9, German CK electronics corporations production).
Sample:The cream that embodiment 4-6 is prepared.
3. Subject Population and testing time
Totally 150 people, age between 34~48 years old, are divided into 3 groups.
Volunteer's usage time:Sooner or later the cream for having effects that antiallergic and releiving smeared 1 embodiment 4-6 and prepared each daily
Frost.
Testing time:Test in one week is primary, tests 4 weeks.
4. experimental method
(1) before subject smears sample, first examination Test sites is cleaned, sample is smeared after drying.The left and right arm of subject
The tested region in inside and control zone, the area of each 4 × 4cm of determination sizes is as Test sites.
(2) subject takes appropriate cream painting to be uniformly put on test zone.Subject uses bare substrate in check plot simultaneously
Domain, it is sooner or later each daily to smear 1 time.During experiment, subject cannot smear any cosmetics in Test sites.
(3) subject's same time weekly after sample is used continuously, using dermal melanin and ferroheme tester with
Lab color difference meters test the variation of skin color, are averaged, are shown in Table 9:
