The antibacterial activities of five brands of household disinfectants were obtained from different locations within the Federal Capital Territory, Nigeria and comparatively studied using the Rideal Walker Phenol coefficient test and quantitative suspension test.

The active compounds of the products according to their respective labels were: D1-(Chloroxylenol 4.8%), D2(Dichloroxylenol 2%), D3(Chlorhexidine gluconate 0.3% and cetrimide 3%), D4 (Dichlorometaxylenol 2.5%), D5-(Chlorhexidine gluconate 0.3% and cetrimide 3%).
