What is not in Loo Cleaner Tabs?
✓ What is not in there
Loo Cleaner Tabs are a dry tablet with no solvent and no added fragrance, so there is nothing in them that evaporates off as a volatile organic compound (VOC). They are designed to clean the bowl, lift mineral staining, and rinse away with the water.

What do these ingredients mean for septic and greywater systems?
✓ Why the absence list matters here
Septic compatible when used as directed, and the ingredient list is the reason. No chlorine bleach and no quaternary ammonium disinfectant, which are the two things that knock over the bacteria a septic tank or an aerated wastewater treatment system depends on. No phosphates either.
Use only as directed. One tab per toilet, dropped straight into the bowl.
Never pour undiluted product into a septic tank, greywater line or inspection opening.
Avoid excessive use beyond normal cleaning. More product does not clean better and it loads the system.
⚠ If you reuse treated water on the garden, three things change the answer
Greywater reuse is not only about the product. It depends on your soil type, since clay and sandy soils handle irrigation water differently. It depends on what you are watering, because edible crops carry stricter rules than ornamentals. And it depends on your local council, since requirements vary by state and council area. Check your local guidelines, and treat your system manufacturer's approved-product list as the final word.
Where can I find the Safety Data Sheet?
✓ Safety Data Sheet
A technical document for regulatory and workplace safety compliance. Most people at home won't need it. Handy if you keep a workplace chemical register.
Get the Safety Data Sheet
Heads up before you tap. The Safety Data Sheet is a regulatory document written for workplace safety officers, first responders and waste handlers. It uses chemistry and hazard classification language and it is not designed as a customer FAQ.
If you are asking about ingredients, sensitivity or everyday use, the breakdown above and the product page will get you there faster.
Still need it? It is a standardised 16-section PDF covering hazards, first aid measures, handling and storage, and disposal.
