Kill Claims Are Not Marketing Language

Walk through any cleaning supply aisle and you will see dozens of products making claims about eliminating bacteria, fighting germs, and protecting surfaces. Most of these statements are marketing. Kill claims are different.

In Canada, a disinfectant kill claim is a regulated assertion. Before a manufacturer can state that a product kills a specific pathogen, the product has to meet Health Canada’s efficacy standards for that claim under the stated conditions. There are two routes to a Drug Identification Number (DIN). Under the monograph pathway, the manufacturer attests that the product fully conforms to Health Canada’s Hard Surface Disinfectants Monograph and keeps its efficacy data on file. Pathogen-specific claims beyond the monograph go through a full review, where the manufacturer submits safety and efficacy evidence. Since the Biocides Regulations came into force on May 31, 2025, new surface disinfectants are authorized as biocides and carry an 8-digit identification number instead of a new DIN. Either way, the kill claim then appears on the label as a legally registered statement.

This matters enormously for facility managers and procurement teams. A product that says kills 99.9% of bacteria without a DIN is making a general marketing claim. A product with a DIN that lists Staphylococcus aureus, Influenza A, and norovirus in its registered claims is telling you, with Health Canada’s backing, exactly what it will eliminate and under what conditions.

The Four Components of a Kill Claim

Every legitimate kill claim on a Health Canada registered disinfecting wipe contains four elements. Understanding each one helps you evaluate whether a product is genuinely suitable for your setting.

1. The Named Pathogen

The kill claim specifies the exact organism the product is proven to eliminate. This may be a bacterium (such as MRSA or E. coli), a virus (such as norovirus or influenza A), or a fungus (such as Candida auris). A product that lists a specific pathogen has been tested against that organism. A product that does not list it has no registered claim against it and cannot be assumed to kill it.

This is why reviewing the full kill claim list before purchasing is essential for regulated settings. A wipe that kills MRSA but has not been tested against C. diff is not suitable as a sole disinfectant in a long-term care facility where C. diff is an active concern.

2. The Required Concentration

Kill claims specify the active ingredient concentration at which the product achieves its stated kill. This is why dilution matters in liquid disinfectants, and why wipe saturation matters in commercial wipe products. A wipe that dries out in the canister or is underloaded with solution during manufacturing may not deliver the required active ingredient concentration to the surface, making the kill claim effectively void in practice.

When evaluating wipe products, ask suppliers for their quality control documentation on solution loading per wipe. Consistent saturation is a manufacturing standard, and it is one where product quality can vary between suppliers.

3. The Dwell Time

Dwell time is the period the surface must remain visibly wet with the product for the kill claim to be achieved. It is listed on the product label for each registered pathogen and it is not optional. A surface that dries before the dwell time has elapsed has not been disinfected to the standard claimed, regardless of the product used.

4. The Surface Type

Kill claims are tested on specific surface types, typically hard, non-porous surfaces such as stainless steel, plastic, and glass. Using a disinfecting wipe on a porous surface, a fabric, or an incompatible material does not guarantee the kill claim applies. Always confirm that the surfaces in your facility match the surface types referenced in the product’s registered kill claims.

Common Pathogens and the Settings That Require Their Kill Claims

How to Read Kill Claims on a Label

When reviewing a disinfecting wipe product for procurement, here is what to look for on the label and in the product’s Health Canada registration:

• Drug Identification Number (DIN): Confirms Health Canada registration. A disinfecting wipe must carry a Health Canada DIN (or, for products authorized under the Biocides Regulations since May 31, 2025, an 8-digit biocide identification number). Without one, any disinfectant claim is unregistered and cannot be relied upon in a regulated environment.

• Pathogen list: The specific organisms the product is registered to kill. Match this list against the pathogens of concern identified in your facility’s infection control protocol.

• Dwell time per pathogen: Note that dwell times may vary by organism. A product may achieve a 30-second kill on influenza A but require 4 minutes for C. diff. The longest required dwell time for your highest-priority pathogen is the one that governs your protocol.

• Active ingredient and concentration: Typically a quaternary ammonium compound (quat), hydrogen peroxide, or sodium hypochlorite (bleach). Each has different compatibility with surface types, materials, and adjacent products. Bleach-based wipes are the most common choice for C. diff claims but are not appropriate for all surfaces.

• Directions for use: Health Canada registered products include specific use instructions that are part of the registered claim. Using the product in a manner inconsistent with those instructions (wrong surface type, insufficient wet contact time, improper storage) can invalidate the kill claim.

Why Kill Claim Review Belongs in Your Procurement Process

For many facilities, wipe procurement is treated as a commodity purchase. A buyer compares price per wipe, places an order, and moves on. Kill claim verification is rarely part of the conversation at the purchasing stage, even in settings where it clearly should be.

The consequence of that gap shows up in two ways. First, operationally: staff follow a cleaning protocol using a product that does not achieve the kill claims the protocol assumes, creating a false sense of compliance. Second, legally: in the event of an infection outbreak, a facility that cannot demonstrate it used a product with registered kill claims against the relevant pathogen is in a significantly weaker position.

A straightforward kill claim review at procurement does not take long and provides durable documentation that the product selected matches the facility’s infection control requirements. Roxton can provide its DIN confirmation, Safety Data Sheet and kill claim listing on request to support that process.
