This page covers household chlorine bleach containing sodium hypochlorite (NaOCl). Concentrations differ, so dilution and permitted uses must follow the original label and current Hong Kong official guidance.
How to identify it
Find sodium hypochlorite, NaOCl, the concentration and use or dilution directions on the original label. A white bottle, laundry picture or liquid colour is not a reliable identity test.
Common confusion
This item
Household Chlorine Bleach

How to identify it
Laundry detergent cleans clothes, fabric softener is used in the rinse stage, and chlorine bleach states sodium hypochlorite on the label. A toilet product labelled sodium hypochlorite or NaOCl remains chlorine bleach; other toilet cleaners are a separate category. Similar packaging never makes cleaners interchangeable or mixable. Confirm a non-bleach disinfectant from its original ingredient and use label; products containing sodium hypochlorite remain bleach. Toilet cleaner, disinfectant and bleach are not interchangeable and must never be mixed.
Common Hong Kong household uses
Only for bleaching or disinfecting surfaces the product label permits. Remove visible soil first, then measure and dilute with cold water as the label or Centre for Health Protection guidance requires.
Use & label checks
Ventilate the area, wear protection required by the label and use one product at a time. Never mix bleach with any other household cleaner. Rinse thoroughly with water before changing from a cleaner to bleach.
Safe storage
Keep in the closed, labelled original container in a cool, shaded place out of children's reach. Hong Kong official guidance says diluted solution should be used within 24 hours.
