I used to spray myself with perfume every single morning without thinking twice. During my first pregnancy, my favourite scent started making me nauseous. Not just "oh that's strong" nauseous. Properly, pull-over-the-car nauseous.
I assumed it was hormones. It probably was, partly. But when I started digging into why, what I found stopped me reaching for that bottle again.
The fragrance I was spraying on myself every day wasn't just "perfume." It was a chemical cocktail I had no way of identifying.
What Does "Fragrance" Actually Mean on a Label?
Here's the legal loophole that keeps most of us in the dark.
Under Australian labelling law, brands must list every cosmetic ingredient except one.
Fragrance (or parfum, if they want to sound fancy about it).
That single word can legally represent hundreds of individual chemicals. The formula is protected as a trade secret. You have no way of knowing what's in there.
These blends can include:
- stabilisers
- solvents
- synthetic aroma chemicals
- scent fixatives
- preservatives
Many perfumes rely on these synthetic chemicals to make scent stronger and longer-lasting. For people reducing their exposure to unknown compounds, that's a problem. You're spraying something on your skin every day without knowing what it actually is.
The Chemicals Hidden Behind "Fragrance"
Some of those undisclosed chemicals are endocrine disruptors. Meaning they interfere with your normal hormone production.
Phthalates are widely used to make fragrance last longer on skin. They're plasticisers that stabilise scent molecules. They're classified as endocrine disruptors.
Parabens are preservatives used to extend shelf life. Research published by the National Library of Medicine found associations between paraben exposure during pregnancy and thyroid dysfunction in newborns. The thyroid regulates metabolism, growth, and development. If it's disrupted early, it affects everything downstream.
Synthetic musks are used to extend and anchor scent. Some have been detected in human tissue and breast milk. Let that sink in.
These studies show associations, not proven causation. But they're worth knowing about when the word "fragrance" is the only information you have.
Why Your Body Reacts Differently During Pregnancy
During pregnancy, hormonal changes increase your sensitivity to volatile compounds in the air. Some fragrance chemicals may also interact with hormone pathways that are already active during pregnancy, which can heighten the reaction.
Your nausea isn't weakness. It's your body telling you something's off.
But here's the thing: you don't have to be pregnant to be affected by endocrine disruptors. You're exposed to them every day through every scented product in your routine. Shampoo. Deodorant. Body wash. Moisturiser. Each one potentially carrying its own undisclosed fragrance blend.
It adds up. And it matters.
The Switch: Essential Oil Perfumes vs Synthetic Fragrance
Natural perfumes use essential oils derived from plants instead of synthetic fragrance chemicals. They list their ingredients in full. No "fragrance" catch-all. No hidden chemicals.
This isn't about being afraid of your perfume. It's about knowing what you're putting on your body.
Solid perfumes made with essential oils contain no alcohol, no synthetic fixatives, and no hidden fragrance blends. They're also plastic-free and travel-friendly. For people reducing their exposure to synthetic chemicals, solid essential oil perfume is a practical switch.
How to Start Reducing Your Exposure
Switching everything overnight isn't realistic. But these small changes can help reduce daily exposure:
- Choose products that list every ingredient in full
- Look for essential oil-based perfumes instead of synthetic fragrance
- Avoid products that use "fragrance" or "parfum" as a catch-all
- Apply scent to clothing rather than directly to skin if you're sensitive
- Start with one switch and go from there
Most people start with perfume, then move to deodorant, then shampoo. You don't have to do it all at once. Just start somewhere.
FAQ: Synthetic Fragrance and Your Health
What does "fragrance" mean on a perfume label?
It is a legally protected catch-all term. One word can represent hundreds of individual chemicals that brands are not required to disclose. Fragrance formulas are classified as trade secrets under Australian labelling law.
Can synthetic fragrance affect thyroid function?
Some fragrance preservatives, particularly parabens, have been studied for their effects on thyroid function. Research from the National Library of Medicine found associations between paraben exposure during pregnancy and thyroid dysfunction in newborns. The research shows associations, not proven causation. More research is ongoing.
What are phthalates and are they in perfume?
Phthalates are chemicals used to make fragrance last longer on skin. They are classified as endocrine disruptors, meaning they can interfere with normal hormone production. Because fragrance formulas do not require ingredient disclosure, it is difficult to know which products contain them.
Why did my perfume make me feel sick during pregnancy?
Hormonal changes increase sensitivity to volatile compounds in the air. Some fragrance chemicals may also interact with hormone pathways that are already active during pregnancy, which can heighten the reaction. Your body was signalling that something wasn't right.
What is a natural perfume made of?
Natural perfumes use essential oils derived from plants instead of synthetic fragrance chemicals. They list their ingredients in full, with no "fragrance" or "parfum" catch-all on the label. You know exactly what you're spraying on your skin.
Is solid perfume better than spray perfume?
Solid perfumes made with essential oils contain no alcohol, no synthetic fixatives, and no hidden fragrance blends. They are also plastic-free and travel-friendly. For people reducing their exposure to synthetic chemicals, solid essential oil perfume is a practical and easy switch.
Why should I care about fragrance if it's legal?
Just because something is legal doesn't mean it's safe. The fragrance loophole exists because the industry lobbied for it. You have a right to know what you're putting on your body. Choosing transparent brands is one way to reclaim that control.
Real Talk.
Synthetic fragrance is more common than most people realise. And the labelling loophole means most of us have no idea what we're actually applying.
Your nausea, your sensitivity, your gut feeling that something's off. That's not weakness. That's your body trying to protect you from unknown chemicals.
Choosing products with transparent ingredient lists is one of the simplest ways to take back a little control. And it starts with swapping one bottle at a time.
Viva La Body's Natural Perfume Collection uses essential oils only. No synthetic fragrance. No phthalates. No "parfum" catch-all. Every ingredient is listed. Every ingredient belongs there.
Make the switch. Your hormones will thank you.
