2 pairs of skin irritation tests:
Select one of healthy albino guinea-pig for use, back both sides unhairing.One side is the trial zone, and opposite side is the check plot.Sample is smeared in the trial zone, does contrast with the warm water cleaning check plot with distilled water behind the 4h, respectively at observing guinea pig skin variant situation behind 12h, 24h, the 72h.
The experiment of 3 bin stabilities
The available chlorine content of napkin paper thimerosal can show the size of napkin paper sterilizing ability, and available chlorine content is stable more, shows that napkin paper is long more storage period, and sterilizing ability is lasting more.
Three samples that available chlorine content is different are contained in port grinding bottle, and lucifuge stores under the room temperature condition, opens bottle stopper one time in every month, opens plug time 5min at every turn, regularly do available chlorine content and measure, and the results are shown in Table 4.
Table 4 thimerosal available chlorine content changes
The preparation of 3 napkin paper thimerosals:
The disinfectant kind that contains effective chlorine is a lot, as Babysafe, toluene-sodium-sulfonchloramide, AONACID, bleaching powder, bleaching powder etc.Their Disinfection Effect is good, but decomposes rapidly because of the HClO that generates is unstable behind the wiring solution-forming.And medical profession is commonly used to kill the peracetic acid disinfectant of hepatitis B, although it is a kind of disinfectant of broad-spectrum high efficacy, also has the labile defective of poor stability.Analyze in sum, if commercially available various disinfectants exist easy decomposition situation just to be difficult for manufacturing the disinfectant of napkin paper.Therefore need compound again preparation, the thimerosal for preparing should satisfy two conditions: (1) is kill bacteria and virus rapidly, (2) good stability, and storage period is long.Finally to develop a kind of sterilizing ability strong through a large amount of experiments, the thimerosal of good stability, select for use cheap and available chlorine content up to more than 80% bleaching powder (Ca (ClO)
23H
2O) be primary raw material, be equipped with other auxiliary material and form, see Table 5.
Table 5 napkin paper thimerosal specifications of raw materials and proportioning
| The raw material title | Specification | Weight (Kg) |
| Bleaching powder | Available chlorine content＜80% | 8～10 |
| Stabilizing agent | Pharmaceutical grade | 5 |
| Alkali | |
2～6 |
| Essence | Edible | In right amount |
| Distilled water | Common | 150 |
At first water-soluble bleaching powder during preparation, the elimination sediment adds the adjusting PH with base value in leaching solution, and question response is back elimination Ca (OH) fully
2Gelatinous precipitate adds stabilizing agent and an amount of essence in the clear liquid that leaches.Also will test available chlorine content with simplified method at last, it is that 0.9～1.0% storage is standby that available water transfers to effective chlorine.
4 results and discussion
(1) interpretation
In the killing effect experiment, from the interpretation of result of table 1, table 2 as can be seen, the napkin paper thimerosal just has the good sterilization effect to Escherichia coli and staphylococcus aureus after 30s.And antiseptic napkin has also had the good sterilization effect to Escherichia coli and staphylococcus aureus after 60s.The result shows from table 3, and it is qualified that thimerosal destroys HBsAg in 5min, promptly hepatitis B had good quick inactivating effect.
In the skin irritation test, show, do not see in each stipulated time that trial zone skin and check plot skin have ANOMALOUS VARIATIONS from the situation result who observes the guinea pig skin variation.According to " skin irritatin test " grade scale regulation, this napkin paper should belong to the thing that has no stimulation.
In the bin stability experiment, analytical table 4 results see that from the test result of storing the thimerosal in 1 year the amplitude of variation of available chlorine content is very little, about about 12%; Store two annual bearings and see available chlorine content amplitude of variation about 30%; Therefore illustrate that this thimerosal is more stable, lucifuge sealed storage under the room temperature, the term of validity can reach more than the 1a.
(2) the thimerosal preparation is analyzed
Killing the hepatitis B common disinfectants is Peracetic acid, but it is stable inadequately, decomposition failure very easily, and breakdown:
And the aqueous solution of bleaching powder and airborne CO
2Gas or with acidic materials reaction also decomposition failure rapidly, react as follows:
Ca(ClO)
2+2H
2O＝Ca(OH)
2↓+2HClO
Ca(OH)
2+CO
2＝CaCO
3↓+H
2O
HClO＝HCl+[O]
HClO+HCl＝Cl
2↑+H
2O
Selecting bleaching powder for use is main material, mainly is the available chlorine content height because of it, and wide material sources are cheap.But also there is instability problem in bleaching powder, and for capturing this difficulty, we have taked two ways, the one, add the pH value of an amount of alkali regulator solution, and the 2nd, add an amount of salt and make stabilizing agent.According to report, the bactericidal effect of hypochlorous acid HClO is better than hypochlorite ClO
-Virus killing tens times of effect, why bactericidal effect well just has been this two kinds of coefficient results of composition to bleaching powder.The bleaching powder main component is calcium hypochlorite Ca (ClO)
2, be dissolved in hydrolysis: ClO
-+ H
2O → HClO+OH
-, in the aqueous solution, decompose and the hypochlorous acid that generates is very unstable.HClO → ClO+H
+, by a large amount of experiment showed, if the pH value of solution is acid, though help the generation of HClO, HClO and acid also can be reacted rapidly and be generated Cl
2And decompose, instead make ClO
-Concentration descend, cause effective chlorine density to reduce.If the pH value of solution is than strong basicity, then suppressed ClO
-Abundant hydrolysis, HClO concentration is reduced.Therefore, the pH value of coming promoting or transferring joint thimerosal with a spot of alkali lye can make the HClO and the ClO that keep q.s in the thimerosal to desired value
-But, keep stable in the available chlorine content long term.
