Years ago, I stood in a store aisle holding a product boldly labeled “fragrance free.” On the surface, it felt like a safe choice—especially for someone trying to reduce chemical exposure at home. But something didn’t sit right. I had already seen too many clients react to products that were supposedly “safe,” and I’d personally experienced headaches and irritation from items that promised to be gentle.
So I did what most people don’t have the time—or energy—to do. I looked deeper.
What I found changed how I approach labels forever.
“Fragrance‑free” doesn’t always mean what we think it means. And once you understand how ingredients are disclosed—and what’s not required to be disclosed—you start to realize why so many people still react to products that claim to be better choices.
This is why I don’t rely on marketing claims. I rely on data.
And in this post, I’m going to show you how to do the same—without turning this into a second full‑time job.
Health Risks of Fragrances (What the Research Actually Shows)
Fragrance is not a single ingredient. It’s a catch‑all term that can legally represent hundreds to thousands of undisclosed chemicals.
From a building biology and environmental health perspective, this matters because many fragrance compounds are known to:
- Irritate the respiratory system – Fragranced products are associated with asthma attacks, airway inflammation, and reduced lung function. Population studies published in Environmental Health Perspectives have shown that fragranced consumer products are a significant source of indoor air pollution and respiratory symptoms.
- Affect the nervous system – Headaches, migraines, dizziness, and cognitive effects such as brain fog are commonly reported. A large survey study published in Air Quality, Atmosphere & Health found that fragranced products triggered neurological symptoms in a substantial portion of the population.
- Disrupt endocrine function – Certain fragrance ingredients (including phthalates, often used as fragrance solvents) are known endocrine disruptors. The CDC has repeatedly reported widespread human exposure to these compounds through everyday products.
- Act as chemical sensitizers – Repeated low‑level exposure can increase sensitivity over time, especially in children and individuals with compromised detoxification pathways.
Another under‑discussed issue is secondary pollutant formation. Research from the U.S. Environmental Protection Agency shows that fragrance VOCs—such as terpenes—can react with indoor ozone to form formaldehyde and ultrafine particles. These secondary pollutants may be more irritating than the original fragrance itself, particularly in tightly sealed homes.
The takeaway is simple but important: fragrance exposure is not benign, especially in indoor environments where air exchange is limited and exposure is chronic.
Why “Fragrance Free” Doesn’t Mean Healthy
Here’s the hard truth: “Fragrance free” is a marketing term, not a regulated health standard.
In the United States, manufacturers are not required to disclose individual fragrance ingredients because fragrance formulations are protected as trade secrets under federal law. This means a product can legally be labeled fragrance free while still containing fragrance‑related chemicals.
A product labeled fragrance free may still include:
- Masking fragrances designed to neutralize odors
- Fragrance components embedded within other ingredients
- Preservatives or solvents that off‑gas and behave similarly to fragrance chemicals
This explains why two products—both labeled fragrance free—can have completely different chemical profiles and very different impacts on indoor air quality.
For people with asthma, migraines, eczema, chemical sensitivities, autoimmune conditions, or hormonally driven symptoms, this distinction is critical. Many of the families I work with feel discouraged because they believe they’ve made all the “right” choices—yet symptoms persist.
That’s not a personal failure.
It’s a labeling problem.
How to Read an MSDS (Without Feeling Overwhelmed)
An MSDS—now more accurately referred to as an SDS (Safety Data Sheet)—is one of the most transparent documents a manufacturer provides.
Unlike product labels, SDS documents are created for occupational safety and regulatory compliance, not marketing. While they are not perfect, they often reveal far more than front‑of‑package claims.
Step 1: Locate the SDS
- Search online: Product name + SDS
- Check the manufacturer’s website under safety, compliance, or technical documentation
If a company makes this information difficult to find, that alone is meaningful data.
Step 2: Focus on the Sections That Matter
You do not need to read all 16 sections.
Start here:
- Section 2 – Hazard Identification: Look for health effects, signal words, and exposure warnings
- Section 3 – Composition / Ingredients: Note proprietary blends, fragrance references, or undisclosed components
- Section 8 – Exposure Controls: Pay attention to ventilation recommendations or protective equipment
- Section 11 – Toxicological Information: This section often reveals irritation, sensitization, or chronic exposure risks
Step 3: Interpret the Language
Pay close attention to phrases such as:
- “May cause respiratory irritation”
- “May affect the central nervous system”
- “Prolonged or repeated exposure”
If a product requires gloves, eye protection, or mechanical ventilation for workers, it’s reasonable to pause before assuming it’s harmless for daily use in a home—especially around children.
How to Do Your Own Research Without Stressing Yourself Out
One of the biggest barriers to healthier choices isn’t lack of care—it’s overwhelm.
You do not need to research everything at once. In fact, trying to do so often backfires and leads to decision fatigue.
Here’s a grounded approach I recommend:
- Work one product category at a time (cleaners, laundry, personal care, air fresheners)
- Prioritize exposure over perfection (daily use, airborne products, large surface areas)
- Use symptoms as data alongside research
- Stick with brands that consistently disclose information
Reduction lowers overall toxic load. And just as importantly, a calmer approach supports the nervous system—which plays a real role in resilience and recovery.
Brands I Trust (and Why Transparency Matters)
I don’t trust brands because they use the right buzzwords. I trust them because of their behavior over time.
The companies I’m most comfortable recommending tend to:
- Fully disclose ingredients beyond the label
- Make SDS documents easy to access
- Avoid fragrance entirely rather than relying on masking agents
- Respond clearly and directly to ingredient questions
Transparency is not perfection—it’s accountability. And it matters far more than any single marketing claim.
Final Thoughts: Labels Are the Starting Point, Not the Finish Line
If there’s one thing I want you to take away from this, it’s this:
“Fragrance free” is not a guarantee of safety—it’s an invitation to look deeper.
Your home should support your health, not quietly work against it.
Learning how to read an SDS is one of the most empowering skills you can develop as a homeowner. It moves you away from marketing claims and toward informed, confident decisions.
Frequently Asked Questions About Fragrance‑Free Products
Is fragrance free the same as unscented?
No. Unscented products often contain masking fragrances designed to neutralize odor. These masking agents can still release fragrance chemicals into indoor air.
Are natural or essential‑oil fragrances safer?
Not necessarily. Essential oils are complex chemical mixtures and can still trigger respiratory irritation, migraines, or sensitization—especially in enclosed indoor environments.
Why do companies hide fragrance ingredients?
Fragrance formulas are protected as trade secrets under U.S. law, allowing manufacturers to avoid full ingredient disclosure.
Do I need to avoid all fragrance forever?
For some people, temporary avoidance helps reduce symptoms and overall toxic load. For others, long‑term avoidance is necessary. This is highly individual.
What’s the most impactful step I can take?
Start by removing fragranced products that affect indoor air quality first—air fresheners, candles, sprays, and heavily scented cleaners.
