[The observation on the disinfecting efficiency of the disinfectant 93]

Disinfectant 93 is a colorless and transparent liquid. It contains surfactant and hand-protective. Its major component is Di(octyl amino-ethyl) glycine hydrochloride. 99.8% natural bacteria could be removed from the medical staff's hands by using the disinfectant 93 to scrub for 1 min twice. According to the standard of the Ministry of Public Health, it is allowed that the amount of bacteria on the hands is less than equal to 10cfu/cm2 under the condition of class III, and less than equal to 5cfu/cm2 under the condition of class I [symbol: see text] II, in which the qualification rate reached to 100% and 98%, respectively. The average elimination rate of natural bacteria reached to 99.5% and 99.3%, when the hands of surgical operators were disinfected with the disinfectant 93 after scrubbing and brushing with soap. The results showed that disinfecting efficiency of the disinfectant 93 was stronger, its continued effects were also visible, and it wasn't irritative for skin.
