Step 1,2 liang of groups are mixed fully and mixed, and add 50g water and stir to clarify, be product.
The product that example 1 is obtained carries out following series of experiments:
Antiseptic effect checking: microorganism detection total number of bacterial colonies
Examination criteria: GB15979-2002 appendix B2, total number of bacterial colonies and initial contaminated bacteria detection method.
Sample treatment: evenly spray sample 0.15g on the sanitary towel top layer, the 1g of clip sanitary towel is dipped in the 100ml normal saline.Occurrence sees Table 2:
Table 2: microorganism detection total number of bacterial colonies testing result
Figure G200910070430XD00041
This result shows that this product has very strong killing action to microbial bacterial, within a certain period of time can anti-bacteria regrow, for the women provides safer physiological hygiene environment.And the sanitary towel that adds medicament by the stability tests in 2 years still possesses very strong killing rate to microbial bacterial.
The method of testing of refrigerant degree and checking:
Method 1
Accurately spray the 0.15g sample in the sanitary towel top layer, in all ages and classes section women, do respectively refrigerant degree test.Test result sees Table 3.
Table 3: refrigerant degree test result
Ages 15-22 year (100 people) 23-30 year (100 people) 30-40 year (100 people) 40-50 year (100 people)
Test result The cold degree is as snug as a bug in a rug moderate The cold degree is as snug as a bug in a rug moderate The cold degree is as snug as a bug in a rug moderate The cold degree is as snug as a bug in a rug moderate
The present invention can safeguard the comfortable dry and comfortable environment of women's privates through above-mentioned test proof, and is applicable to the healthy women of all age group.
The method of testing of refrigerant time and checking:
Accurately spray the 0.15g sample in the sanitary towel top layer, in all ages and classes section women, do refrigerant time test respectively.Test result sees Table 4.
