TGA-Approved Disinfectants for Healthcare Cleaning
How the TGA disinfectant registration system works in Australia, what the AUST L number on a product label means, how to search the ARTG to verify kill claims, and how to select the right registered disinfectant for each zone type in your healthcare facility.

How the TGA Registers Disinfectants
In Australia, disinfectants used in healthcare settings are classified as therapeutic goods regulated by the Therapeutic Goods Administration (TGA). Any product that claims to kill pathogens in a clinical or healthcare context must be listed on the Australian Register of Therapeutic Goods (ARTG) before it can legally be supplied for that use. Products making healthcare disinfection claims without ARTG listing are not legally compliant for clinical use — regardless of label language.
The ARTG contains two relevant listing categories for disinfectants. An AUST L number (Listed) indicates a product assessed for safety, quality, and compliance with labelled claims at a level appropriate for lower-risk products — the standard for most healthcare disinfectants. An AUST R number (Registered) indicates higher-level pre-market assessment for more complex or higher-risk products. For accreditation purposes, both confirm the product is on the ARTG with assessed kill claims. Most clinical disinfectants carry AUST L numbers.
The ARTG entry for a listed disinfectant confirms the registered product name, the sponsor (manufacturer or importer), the indications (what the product is listed for), and — most importantly — the kill claims assessed. These claims specify which organisms the product kills, at what concentration, and in what contact time. Using a product outside those conditions does not constitute compliant use even with an AUST L number on the label.
How to Search the ARTG to Verify a Product
The ARTG is publicly searchable at no cost via the TGA website. Every facility manager can independently verify the registration status of any product in their cleaning programme.
The AUST L number alone is not enough: A product with a valid AUST L number used at the wrong dilution does not satisfy the TGA registration requirement. If the ARTG entry specifies 1:100 dilution for bactericidal kill and your facility uses it at 1:200 to reduce product cost, the product is not being used under its registered conditions. The AUST L number does not follow you if you deviate from registered use conditions.
Kill Claims — What Each Means for Zone Selection
The kill claims in a product's ARTG entry determine which healthcare zones it is appropriate for:
- Bactericidal (gram-positive and gram-negative): The minimum for any clinical zone disinfectant. NSQHS Standard 3 reference organisms include Staphylococcus aureus (gram-positive) and Pseudomonas aeruginosa (gram-negative). A product with only gram-positive coverage does not satisfy the standard for clinical zones.
- Virucidal — enveloped viruses: Covers influenza, coronaviruses (including SARS-CoV-2), RSV, HIV, Hepatitis B, and Hepatitis C. Carried by most TGA-registered QAC and hospital-grade alcohol products. Minimum for zones where respiratory or bloodborne virus transmission is a concern.
- Virucidal — non-enveloped viruses: Covers norovirus, adenovirus, and rotavirus. Not carried by most QAC or alcohol products. Specifically required for gastroenteritis outbreak response and faecal-oral transmission zones. Sodium hypochlorite products and specific AHP formulations carry this claim.
- Sporicidal: Kills bacterial spores — specifically Clostridioides difficile. Required for C. difficile terminal cleans. Sodium hypochlorite at appropriate concentration and specific registered sporicidal products carry this claim. QAC and alcohol products do not.
- Fungicidal / Mycobactericidal: Required for immunocompromised patient environments, TB exposure management, or mould remediation. Not required for most general healthcare zones.
Zone-Matched Disinfectant Selection Reference
| Zone / Use Case | Minimum Kill Claim Required | Suitable Product Type | Key Exclusions |
|---|---|---|---|
| General clinical surface — ward bay, consulting room, outpatient | Bactericidal (gram+ and gram−) + virucidal enveloped | TGA-registered QAC or hospital-grade combined detergent-disinfectant | Bactericidal-only products; products without gram-negative coverage |
| Sanitary zone — patient bathroom, toilet, shared facilities | Bactericidal + virucidal enveloped; sporicidal if C. diff present | TGA-registered QAC for routine; sodium hypochlorite 1,000 ppm if C. diff risk | Detergent-only products; alcohol wipes as primary disinfectant |
| Gastroenteritis outbreak — all affected surfaces | Virucidal non-enveloped (norovirus); bactericidal | Sodium hypochlorite 1,000–10,000 ppm; registered AHP with non-enveloped virucidal claim | QAC disinfectants; alcohol-based products — neither kills norovirus |
| C. difficile isolation room terminal clean | Sporicidal with confirmed C. diff spore kill claim | Sodium hypochlorite 1,000 ppm minimum (10-minute contact); registered sporicidal AHP or peracetic acid | QAC; alcohol; standard AHP without sporicidal ARTG claim |
| Blood spill disinfection | Virucidal enveloped (HBV, HCV, HIV) at high organic load | Sodium hypochlorite 10,000 ppm (1%) after cleaning; registered AHP with HBV virucidal claim under organic load | Alcohol — efficacy reduced by blood proteins; QAC at standard concentration unreliable against HBV under organic load |
| Electronic equipment and device surfaces | Bactericidal + virucidal enveloped; surface-compatible with electronics | TGA-registered QAC wipes confirmed compatible with polycarbonate and electronic coatings | Hypochlorite on electronics (corrosive); alcohol 70%+ on polycarbonate screens (degrades coating) |
| Food contact surfaces — aged care dining, nutrition areas | Bactericidal; product must be registered for food-safe use | TGA-registered food-safe surface disinfectant with food-contact claim in ARTG entry | Standard clinical disinfectants not cleared for food contact; high-concentration hypochlorite without rinse step |
Concentration and Contact Time as Non-Negotiable Conditions
A TGA-registered product's kill claims apply only when used at the registered concentration and held on the surface for the registered contact time. These are conditions of registration, not recommendations.
The most common compliance failure is contact time violation: a registered disinfectant is applied and immediately wiped, achieving a cosmetic clean without the dwell time required for pathogen kill. Even with the correct product at the correct concentration, immediate wiping means the kill claims have not been satisfied. The AUST L number does not protect a facility that uses the product incorrectly.
Concentration violations are equally significant. Over-diluting reduces the active ingredient below the assessed level. Under-diluting can damage surfaces and, for certain chemistries, reduce efficacy through product instability. Both directions are non-compliant use of the registered product. Your cleaning staff must know — not assume — the registered concentration and contact time for every product they apply.

Action Steps
- Run an ARTG audit of every disinfectant currently in use at your facility. For every product: confirm the AUST L number returns a current ARTG listing; confirm kill claims match the zones it is used in; confirm registered concentration matches dilution practice; confirm contact time is being observed. Any failure on any check must be corrected before the next accreditation assessment.
- Build your product register from the ARTG entries, not the product labels. The ARTG entry is the authoritative source for kill claims and use conditions. Your product register should cite ARTG-confirmed claims — not label claims, not supplier marketing, not verbal assurance.
- Confirm you have a registered non-enveloped virucidal product in your register. If every product is QAC-based, you cannot manage a gastroenteritis outbreak with compliant chemistry. Add sodium hypochlorite at working concentration — confirmed against the ARTG — before you need it.
- Train cleaning staff on concentration and contact time for every product they use. Staff applying product and immediately wiping are using a registered product in a non-compliant way. Training must cover contact time as a specific, timed requirement — not "leave it a moment".
- Review product register currency quarterly. ARTG listings change without proactive notification. A quarterly check of each product's ARTG status takes minutes and prevents the situation where a delisted product continues to be used as registered.
FAQ
Both indicate TGA-assessed products on the ARTG. AUST L (Listed) is the standard for most healthcare disinfectants — assessed at a level appropriate for lower-risk therapeutic goods. AUST R (Registered) indicates higher-level pre-market assessment for more complex products. For accreditation purposes, both confirm the product is on the ARTG with assessed kill claims. Most clinical disinfectants you encounter will carry AUST L numbers.
No — and it may reduce efficacy for some chemistries. TGA kill claims are assessed at a specific concentration and the product is registered for use at that concentration. Using a higher concentration is not covered by the ARTG listing, may damage surfaces or equipment, and with some formulations (such as certain AHP products) can impair the antimicrobial mechanism. It also effectively means you are using an unregistered formulation that shares an active ingredient with the registered product.
ARTG entries change when a product's sponsor updates the formulation, changes the product name, withdraws the product, or allows the listing to lapse — without necessarily notifying facilities using the product. A product that was ARTG-listed when added to your register may have been delisted since. Quarterly verification of all products catches any changes before they become an accreditation assessment finding.
It depends on the product's registered contact time condition. Some TGA-registered disinfectants — particularly certain QAC formulations — are registered with "allow to air dry" as the contact time condition, which is compliant when followed. For products with a defined timed contact (e.g., "leave wet for 5 minutes"), allowing air drying without timing is not compliant if the surface dries before the contact time is reached in warm or ventilated environments. Check the specific product's ARTG entry for the exact contact time condition.
No — ARTG listing is associated with the product and its sponsor, not a specific distribution channel. A registered product can be purchased from any legitimate supplier. However, always confirm the AUST L number on the physical product received matches your ARTG verification — particularly when switching suppliers or receiving products in different packaging — to ensure you are receiving the registered formulation and not a different product in similar packaging.
