1 SUMMARY OF TESTS BEING EXECUTED WITH OXILITE OR NEUTRAL OXILITE PRODUCED ON WATER-MASTER EQUIPMENT. 2 LABORATORY TEST EXECUTED WITH OXILITE. Bactericidal effect of (ph 2-3, ORP>11mV, 3mg/l) inocolum 1.7 x 1 4 cfu/ml is shown in table 1.

The number of bacteria was reduced below detection limit following incubation in STEL water for 1s. The bactericidal activity of STEL water was similar to that of 8% ethanol, but superior to that of,1 chlorhexidine and,2% povidine iodone. We conclude that STEL water is a low cost but powerful disinfectant.

2 Bactericidal effect of (ph 2-3, ORP>11mV, 3mg/l) inocolum 1.7 x 1 6 cfu/ml is shown in table 2.

3 A > 5log1 reduction in Mycobacterium tuberculosis is indicative of tuberculocidal activity i.e. high level disinfection. This was achieved under clean conditions (absence of organic matter) in 5. Little or no reduction in test mycobacteria was detected in 3 mins when Superoxidised water was tested in the presence of 1% serum (dirty conditions). The sporicidal activity of (ph2-3.5, ORP>115mV, 5mg/l) under clean and dirty conditions is shown in table 4. Log 1 spores (Bacillus subtill var Niger NCTC 173) remaining after exposure to Anolyte or 2% glutaraldehyde. (suspension tests) Contact time 2% glutaraldehyde Clean conditions Dirty conditions Clean conditions Dirty conditions Pre disinfecting challenge min 2 min 5 min 1 min 2 min 3 min 1 hour 2 hours A 6 log1 reduction in test spores was achieved with freshly generated solution in 5. This is far more rapid than the widely used 2% glutaraldehyde. However, when 1% horse serum was added as an organic load no appreciable sporicidal activity was noted in 2 hours. Items must therefore be scrupulously clean before they are disinfected using this agent. Initial cleansing using validated automated system is advised.
