New ultra-low-residue biocide available for RABs

Published: 30-Nov--0001

New biocide is ideal for very high grade zones, RABs and critical product contact areas


When carrying out applications in very high grade areas, such as Grade A and B cleanrooms, or the outer areas of RAB systems, the highest quality of product is required. Very low residue levels are important and Water for Injection (WFI) should be used in disinfectants for direct product contact areas in order to minimise endotoxin levels.

In response to this requirement, Shield Medicare has introduced a new biocide for life science cleanrooms, which is ideal for very high grade zones, RABs and critical product contact areas.

Premier-WFI Klercide-CR Biocide C is a high grade, sterile, broad spectrum rotational disinfectant with sporicidal activity. It is a blend of high grade 6% hydrogen peroxide and WFI. The hydrogen peroxide is the same quality as that which is used for gassing applications, therefore it is a complementary product of equal ‘purity’ for these applications and for the outer areas of RAB systems.

Premier-WFI Klercide-CR Biocide C is suitable for use on all types of hard surfaces in cleanrooms and controlled environments, isolators, LAF’s, equipment exteriors and production vessels. As it is a blend of hydrogen peroxide and WFI, it is very low residue, thereby eliminating the need to wipe down with alcohol or water, and it has endotoxin levels guaranteed to be below 0.25 EU/ml. In addition it can be used safely and effectively as part of a rotation with any other Shield Medicare biocide, or for action point use to remove troublesome organisms.

The biocide blend is 0.2µm filtered, sterile filled and triple bagged under unidirectional flow in a Grade B cleanroom using a strictly controlled and validated process. The trigger spray bottle incorporates an adjustable trigger and the patented SteriShield delivery system, which allows all the liquid to be dispensed, with no wastage, while guaranteeing in-use sterility of six months.
