Is Fragrance-Free the Same as Unscented? No, and Here Is Why It Matters

Is fragrance-free the same as unscented?

No, and the gap between them is the most useful piece of label literacy a Canadian shopper can pick up in one minute.

The convention across the cleaning and personal-care industries is this. Fragrance-free means no fragrance materials were added to the formula. Unscented means the finished product does not smell of anything in particular, and one of the accepted ways to achieve that is to add a masking fragrance that covers the base odour of the raw ingredients. Surfactants, solvents and preservatives do not smell of nothing. Something has to deal with that, and the cheapest something is more fragrance.

So a bottle can carry the word “unscented” honestly, in good faith, while containing added fragrance chemicals. If you are avoiding fragrance because it triggers a headache or an airway, “unscented” has not solved your problem.

We should be honest about the limits of our own knowledge here. We could not find a Canadian regulation that defines either term for household cleaning products. The distinction above is an industry convention, widely used and widely explained, not a legal test. That absence is itself the point of this article.

Why is there no Canadian rule on this?

Because Canadian cleaning-product labelling was built to communicate acute hazard, not to describe contents.

Household chemical products fall under the Consumer Chemicals and Containers Regulations, 2001. That regime requires hazard symbols, warning statements, safety instructions and first-aid statements based on how a product is classified. On ingredients it asks for very little: hazardous ingredients present at 1% or more must be listed in the first-aid statement, in descending order of proportion. Everything below that threshold can be absent. So can the entire fragrance mixture, at any concentration.

A single word like “fragrance” or “parfum” can stand for dozens to hundreds of individual chemicals, protected as trade secret. In Canada it does not even have to appear.

Marketing words get similar treatment. The Competition Bureau’s final greenwashing guidance, published in June 2025, confirms there is no pre-market approval for environmental and health-adjacent claims. The Act prohibits claims that are false or misleading in their literal meaning or their general impression, and it is enforced after the product is on the shelf. The Bureau’s own instruction to businesses is “when in doubt, spell it out”, which is a fair description of what a good label should do and a fair description of what most labels do not.

One small irony worth noticing: Health Canada itself uses the loose word. Its mould guidance repeatedly specifies cleaning with “a small amount of unscented soap solution”, and CMHC says the same. The intent is clearly to keep fragrance out. The vocabulary has just never been tightened.

What is the practical difference between the two labels?

Three habits close the gap:

1. Read the ingredient list, if the company gives one. Canadian law does not require it, so a full voluntary list is a genuine signal rather than a courtesy.
2. Scan for the words that mean fragrance: fragrance, parfum, aroma, “natural fragrance”, “essential oil blend”, and any named oil such as limonene, linalool, lavender or citrus.
3. Prefer a published standard to a claim. Green Seal’s GS-37 standard counts every fragrance component present at 0.01% or more toward the product’s VOC limit, and prohibits formulating with asthmagens, phthalates and formaldehyde donors. That is a written, checkable criterion. A leaf on a bottle is not.

The EWG Verified programme goes further on disclosure specifically, requiring every intentionally added ingredient including each fragrance component, plus the 26 EU-designated fragrance allergens, to be listed. Use that mark for what it is good at, which is transparency. EWG is an advocacy organisation running a paid certification programme, and its hazard-ranking methodology is criticised by many toxicologists, so we would not lean on it for a toxicity judgement.

Who is actually affected by scented cleaning products?

More people than the phrase “fragrance sensitivity” suggests, though the numbers are self-reported and should be quoted as such.

Anne Steinemann’s cross-national population surveys across the US, Australia, the UK and Sweden found 32.2% of adults reported adverse health effects from fragranced consumer products. The figure specific to cleaning is the one that matters to a cleaning company: 15.7% reported health problems from being in a room cleaned with scented products, and 17.4% from air fresheners or deodorisers. Among people with asthma, 57.8% reported adverse effects from fragranced products, including respiratory problems in 43.3%, migraine in 28.2% and asthma attacks in 27.9%.

Read those as “a meaningful share of people report reacting”, not as clinical prevalence. They come from population surveys and self-reported symptoms, and from a single research group. Even discounted heavily, they describe a large enough group that a cleaner walking into a stranger’s home should default to fragrance-free rather than assume it does not matter. If asthma is the reason you are reading this, the application method matters as much as the scent, and we cover that in the safest cleaning products for asthma.

Health Canada’s Healthy Home Guide reaches the same conclusion without any survey: “Minimize the use of scented products, such as plug-in or aerosol deodorizers (air fresheners). These products can hide odours by producing VOCs. VOCs can cause breathing problems, headaches, and irritation to the eyes, nose and throat.” That is the government of Canada advising against fragrance in the home, and it is the strongest single citation on this whole site for why we work the way we do.

Does natural fragrance count?

Yes, it counts, and this is where we argue against a product a lot of natural-cleaning companies happily sell.

Essential oils are terpene-rich by definition. Citrus and pine terpenes such as d-limonene react with indoor ozone to form formaldehyde, hydrogen peroxide and secondary organic aerosol, documented in chamber work at ozone concentrations as low as 17.2 to 21.4 parts per billion. We are not claiming this reaction is producing a measurable dose in a Fraser Valley living room, where outdoor ozone is often modest. We are saying a lemon essential-oil cleaner is a limonene source in exactly the way a synthetic lemon cleaner is, and “scented with real plants” is not a health claim.

Conventional fragrance carries its own separate issue. Phthalates such as DEP are used to make scent last longer, they are endocrine disruptors, and they are not banned from fragranced consumer products in Canada, where they can sit undisclosed under “parfum”. Canada has acted on DEHP in cosmetics, medical devices and children’s vinyl products, but not on fragrance generally. The magnitude of human harm at consumer exposure levels is genuinely debated, so we will not tell you an air freshener is damaging your hormones. We will tell you that the ingredient can be there and you cannot see it.

Where the evidence points most cleanly is at the fragrance-free end of the scale. A 2023 chamber study of 30 cleaning products found conventional products generally emitted more VOCs at higher concentrations than green products, and fragrance-free products emitted the least of all. That study was authored by researchers at the Environmental Working Group, which you should factor in, and earlier headspace work found little difference between green and conventional products, so the green-versus-conventional comparison is contested. The fragrance-free finding is the part everyone’s data agrees on.

The short version

Fragrance-free and unscented are not synonyms. One describes what was left out, the other describes how the bottle smells, and the second can be achieved by putting something in. Neither word is defined in Canadian law for cleaning products, and no Canadian label has to disclose a fragrance mixture at all, so the front of the bottle is the least informative surface on it. Check for a voluntary ingredient list, scan it for fragrance, parfum, aroma and named oils, and give weight to certifications with published criteria.

If you react to scented products, that is exactly why we clean fragrance-free rather than natural-smelling. Our pricing page lists what a visit costs, and the fragrance-free option is not an upcharge. It is just how we work.
