Phthalates, Fragrance & Hormones: What’s the Connection?
Learn how phthalates are linked to hormones, what endocrine disruption means, and why ingredient awareness helps you make confident clean beauty choices.
If you think back to being a teen, or if you are navigating monthly cycles, perimenopause, or menopause, you already know this. Hormones have a way of making themselves known.
They influence how we feel, how we sleep, our energy, our mood, our skin, and how we move through the day. Sometimes everything feels steady and predictable. Other times, not so much.
Hormones may be tiny, but their impact is anything but small.
Lately, conversations about hormone health have expanded into the personal care and beauty products we use every day. You have probably seen phrases like “phthalates (THAL-ates) are endocrine disruptors” floating around online.
Those conversations are referring to how phthalates may interact with the endocrine (EN-duh-krin) system, which is the body’s hormone system. Before we go further, let’s take a moment to explain what that actually means.
What Is the Endocrine System?
The endocrine system is your body’s hormone system. It produces and releases hormones and helps different parts of the body communicate with one another.
These hormones quietly guide things like:
-
Energy and metabolism
-
Stress response and mood
-
Growth and development
-
Reproductive health and hormonal cycles
Hormones work in very small amounts, which means even subtle changes can have an effect. The goal of the endocrine system is balance. When everything is working smoothly, those hormone signals help keep the body steady and supported.
Because this system is so sensitive, researchers pay close attention to anything that might interfere with how those signals are sent or received.
Where Phthalates Come In
Phthalates are a group of chemicals that have been used in a wide range of consumer products. In personal care products, certain phthalates have historically been used to help fragrance last longer, blend evenly, or dissolve scent ingredients more smoothly.
Because phthalates have been so commonly used, they have also been widely studied. Some research suggests that certain phthalates may interact with the endocrine system, which is why they come up so often in clean beauty and hormone health conversations.
Not all phthalates behave the same way, and research is still ongoing. Still, this possible connection is enough that scientists and health experts continue to study them closely.
How Phthalates Have Been Linked to Hormone Interference
Research suggests that some phthalates may affect hormones in a few different ways.
Some may act like hormones, sending signals that do not belong. Others may interfere with normal hormone communication, making it harder for messages to get where they are meant to go. Some may also influence hormone levels by affecting how hormones are made or broken down.
This type of interaction is often referred to as endocrine disruption. It does not point to immediate harm, but it does help explain why long term exposure and cumulative effects are still being studied.
Since hormones help guide so many important processes in the body, even small disruptions may matter over time.
Fragrance, Transparency & Why Labels Can Feel Confusing
One reason phthalates are discussed so often is their connection to fragrance.
In the U.S., fragrance formulas are typically considered proprietary. This means brands are not required to list every individual ingredient that goes into a fragrance blend. Instead, labels often include a single word like “fragrance” or “parfum.”
Without full transparency, that umbrella term may sometimes include ingredients like certain phthalates or other chemicals, unless a brand clearly states otherwise, such as noting that a product is phthalate free.
This does not mean fragrance itself is always harmful. It does mean that consumers do not always have a clear view of what is included, which is why fragrance continues to be a common topic in clean beauty conversations.
Why Awareness Matters
Learning about ingredients like phthalates is not about fear or trying to get everything perfect. It is about understanding what researchers are studying and why certain ingredients raise questions.
Awareness gives us more room to choose.
-
To read labels with a little more confidence
-
To ask better questions
-
To support brands that value transparency
The research around hormones and ingredients is still evolving. But knowledge helps us make thoughtful, informed choices based on what feels right for our bodies and our lives.
At Ivy & Elder, we believe clean beauty should feel supportive, not overwhelming. Education is simply another way we care for ourselves.
