The examples 1 to 3, 6 and 9 were conducted in the same manner as in examples 1 to 3, 6 and 9, respectively, except that no synergist was added, and comparative examples 1 to 3, 6 and 9 were conducted.
Adding the preservative and mildew inhibitor for the cigarette adhesive into the cigarette adhesive according to 0.1 percent of the mass of the cigarette adhesive, and performing a microorganism challenge test according to the microorganism preservative efficacy test standard of United states pharmacopoeia USP27(51), wherein the microorganism strains for the test are as follows: (1) bacteria: pseudomonas aeruginosa (CGMCC 1.2464), Escherichia coli (ATCC 44102), Staphylococcus aureus (CGMCC aureus) CGMCC 1.0089; (2) fungi: candida albicans (CGMCC 2.2086), Aspergillus niger (CGMCC 3.3928).
The numbers of the smoke glue antiseptic and mildew-proof agents obtained in the examples 1-3, 6 and 9 are respectively 1#, 2#, 3#, 6#, and 9#, the numbers of the smoke glue antiseptic and mildew-proof agents corresponding to the comparative examples 1-3, 6 and 9 without the synergist are respectively 1' #, 2' #, 3' #, 6' #and9 ' #, the challenge experiment result is shown in the table 1, and the total number of bacteria and fungi are (cfu/g).
Table 1 corrosion protection challenge test table
As can be seen from table 1, the cigarette glue with 0.1% addition of each preservative and anti-mildew agent was as follows in the preservative challenge test: after the smoke glue preservative and mildew inhibitor is added into a smoke glue product, samples with the numbers of 1#, 2#, 3#, 6# and 9# are correspondingly added, the number of bacterial fungi in the samples with the numbers of 1#, 2#, 3#, 6# and 9# is less than 0.1% of the initial added bacterial quantity on day 7, and the number of bacteria and fungi is continuously reduced on days 14, 21 and 28, which shows that a preservative system of the samples has strong inhibiting and killing effects on microorganisms and passes a preservative challenge test; the experiment results of samples 1' #, 2' #, 3' #, 6' #and9 ' #afterthe preservative mildew inhibitor without the synergist is added into the smoke glue show that the preservative mildew-proof effect is poor, although the survival quantity of bacteria and fungi is continuously reduced within 28 days, the quantity of the bacteria and the fungi in each sample is more than 0.1 percent of the quantity of the initially added bacteria at the 14 th day, which shows that the preservative system has poor effect of inhibiting and killing microorganisms and cannot pass the challenge test.
The results show that the synergist can effectively improve the sterilization effect of the formula of the antiseptic and mildew inhibitor, and plays an important role in the formula.
