The difference between sanitary wipes and disinfection wipes
The microbiological indicators, microbiological indicators, test bacteria suspension concentration, and detection time of the two types of wet wipes are quite different. Compared with sanitary wipes, the testing requirements/test indicators of disinfection wipes are more stringent, which is more effective for disinfection. The choice and amount of agent are more cautious.
At present, the sterilization test of sanitary wet wipes, most testing institutions and wet wipe manufacturers, select the GB15979-2002 sterilization test, the required test bacteria suspension concentration is 1*105-9*105 cfu/ml, the effect is 2, 5 , 10, 20min four time periods, as long as there is a time period when the test data meets the requirements, it can be considered as qualified. The new sanitary wet wipes industry standard (WS575-2017) strictly requires the sterilization performance test of the product to select the corresponding action time according to the use of the product.
The killing index of disinfectant wipes is stricter than that of sanitary wipes. The required test bacteria suspension concentration is 1*108-5*108cfu/ml (bacteria), 1*107-5*107cfu/ml (fungi), The amount of bacteria is higher and the difficulty is greater.
From the perspective of killing index requirements, sanitary wipes are considered to have a sterilization effect if the sterilization of sanitary wipes is ≥90%. The killing index of disinfectant wipes should reach 99.9% (carrier method) and 99.999% (suspension method) (GB "Sanitary Requirements for Wet Wipes Disinfected Products" (draft for comments).
The killing index requirements in the group standard: the log killing value should be ≥ 5.00 (suspension method), the killing log value should be ≥ 3.00 (carrier method), and the disinfection field test killing log value should be ≥ 1.00.
For disinfection wipes, the detection action time requires that the killing index can be reached within the specified time. The biggest difference from sanitary wipes is the addition of regulations on the skin of injection and puncture sites, as well as medical equipment and medical supplies. From the point of view of the action time of the surface of the object, the action time of the disinfectant wipes also needs to be less than the action time of the sanitary wipes, and it is qualified to meet the killing requirements as soon as possible.
