SteriShield Delivery System
It is essential that the disinfectants used to remove contamination do not bring contamination into the cleanroom environment.
The code of GMP requires that:
"Disinfectants used in Grade A and B areas should be sterile prior to use".
It is also important that the integrity of the disinfectant is maintained during use. Validation work in the licensedpharmacy unit of a major UK hospital identified that a standard trigger spray alcohol had been contaminated with fungal spores only eight hours after opening, so this risk must be eliminated.
There are advantages to using a trigger spray to apply disinfectants, but not all trigger sprays protect the sterility of the contents. With a conventional trigger spray contaminated air can be sucked back into the bottle, contaminating the liquid.
In response to this need, Shield Medicare – a division of Ecolab – developed the patented SteriShield DeliverySystem in 1999. It was the first closed trigger spray system, preventing air being drawn back into the bottle. The liquid is held inside a bag. The function of the bottle is simply to enclose and protect the liquid within the bag. The possibility of “suck back” associated with conventional trigger sprays, where airborne contamination can enter the liquid, is eliminated. This provides all the benefits of a trigger spray while guaranteeing the integrity of the contents for three months.
Disinfectants fitted with the SteriShield Delivery System are used in many GMP facilities around the world.
Shield Medicare offers a unique range of broad spectrum biocides in a variety of ready-to-use or concentrate formats, including impregnated wipes (see wipes page for details on these).
