Why understanding Endocrine Disruptors Chemicals (EDCs) might be the most important thing you do for your health today.
By Entela Çeliku, PhD, Chemist & Ingredient Safety Expert at Kungul
They’re silent, invisible, and disturbingly common. Endocrine-disrupting chemicals, known as EDCs, are woven into the fabric of our daily lives, from the lipstick on your lips to the dust in your home. Though we don’t see them, they see us every day, influencing the way our hormones behave, and often not for the better. Hormones regulate everything from metabolism to fertility, from childhood brain development to mood, sleep, and immune balance. And yet thousands of everyday products contain substances that interfere with this delicate balance, sometimes with consequences that only show up years later.
At Kungul, we’re committed to pulling back the curtain and making it easier for you to understand, avoid, and replace the worst offenders.
What Are EDCs, Really?
Endocrine-disrupting chemicals are external substances not made by the human body that interfere with the normal function of hormones. Some mimic natural hormones like estrogen or testosterone, confusing your body’s messaging system. Others block hormone receptors or disrupt how hormones are synthesized, transported, or broken down. Hormonal communication is how your brain speaks to your organs, and how your organs speak to each other. So when that communication is hijacked, even at very low doses, vthe result can be widespread imbalance.
For example, phthalates (commonly used in fragrances and plastics) disrupt testosterone production. Brominated flame retardants, found in furniture and electronics, interfere with thyroid hormones, which are essential to brain development in infants and children. And once exposed, the effects can be subtle, delayed, and long-lasting.
How EDCs Affect Your Health
The health consequences of EDC exposure are now well-documented across global studies. These include:
- Reproductive issues such as infertility, early puberty, endometriosis, and low sperm count.
- Neurological impacts including ADHD, mood disorders, and reduced cognitive performance.
- Metabolic disorders like insulin resistance, obesity, and type 2 diabetes.
- Hormone-dependent cancers including breast, testicular, prostate, and thyroid cancers.
- Early puberty in girls, now more common than ever, with links to later risks like breast cancer and cardiovascular disease.
Perhaps most concerning is the vulnerability during key life stages, pregnancy, infancy, and puberty when the endocrine system is developing. Disruption during these periods can have lifelong or even transgenerational consequences.
Where Are You Exposed?
Unfortunately, EDCs are not rare ingredients, they’re everywhere. In your water, in your furniture, and especially… in your bathroom cabinet. Let’s take a closer look at common endocrine disruptors in cosmetics and personal care products:
The Hormone Disruptors Hiding in Your Skincare Routine
While your makeup bag might seem harmless, many of its contents are anything but. The beauty industry has long relied on synthetic chemicals to preserve, scent, stabilize, and protect products but at a cost to your hormonal health.
Here are some of the most problematic EDCs found in everyday personal care:
Parabens
These are synthetic preservatives found in moisturizers, foundation, shampoo, shaving foam, and more. On ingredient labels, look for names like Methylparaben, Ethylparaben, Propylparaben, and Butylparaben.
Parabens can mimic estrogen and have been detected in breast tissue samples, raising concerns about their role in hormone-related cancers and fertility disruption.
Oxybenzone (Benzophenone-3)
A UV filter commonly found in sunscreens and SPF-infused cosmetics.
Oxybenzone can disrupt hormone function and has estrogenic effects. Studies have found it in the urine of nearly every American tested. It has also been banned in places like Thailand, Hawaii, and Palau for its environmental impact on coral reefs.
4-Methylbenzylidene Camphor (Enzacamene)
Another UV filter used in sunscreen and anti-aging creams.
Banned in the EU as of 2024 due to endocrine-disrupting concerns, with all affected products required to be removed or reformulated by 2025.
Still permitted in the UK, even though it’s also banned in the USA and Japan.
Triclosan
An antimicrobial preservative once common in soaps and toothpaste. While banned in U.S. hand soaps, triclosan is still present in various cosmetic and hygiene products.
It affects thyroid hormone activity and may contribute to antibiotic resistance, creating a dual health risk.
What’s hidden under “fragrance”?
Manufacturers can legally hide dozens to hundreds of chemicals under the word “fragrance” or “parfum” without disclosing them individually. This is considered a trade secret in both the EU and the U.S.
Some of the common endocrine-disrupting chemicals that can be found in these mixtures include:
- Phthalates (especially DEP – diethyl phthalate): used to make scents last longer; known to disrupt testosterone and affect male reproductive development.
- Synthetic musks (e.g., galaxolide, tonalide): can accumulate in the body and have weak estrogenic effects.
- Benzophenones: used in some fragrances and linked to estrogenic activity.
- Styrene and lilial (butylphenyl methylpropional): linked to hormone disruption and recently restricted in the EU.
Why this matters
Fragrance compounds:
- Can mimic estrogen or block androgen receptors
- Are absorbed through the skin, inhaled, and sometimes ingested
- Can bioaccumulate, especially synthetic musks, which are detected in human fat, breast milk, and even cord blood
The Problem With Labels
One of the reasons EDCs continue to thrive in consumer products is that they’re often not clearly labeled. Ingredient lists might hide toxic compounds behind umbrella terms like “fragrance,” or omit them entirely if they’re used in packaging rather than the product itself.
Even worse, companies may reformulate products without notice, meaning that what was considered safe a year ago may not be safe today. Scientific testing struggles to keep up with the pace of product innovation and marketing.
Consumers are left in the dark, unless they know how to read between the lines.
What You Can Do to Protect Yourself
It’s nearly impossible to avoid all endocrine disruptors, but you can dramatically reduce your exposure with a few smart steps:
- Switch to safer personal care products. Use tools like the Kungul app to scan ingredients and find clean alternatives. Prioritize products that are fragrance-free, paraben-free, and phthalate-free.
- Avoid heating food in plastic or storing it in single-use containers. Use glass, stainless steel, or ceramic instead.
- Filter your tap water using a filter that removes pharmaceutical and pesticide residues and choose organic produce when possible
- Ventilate your home daily and vacuum regularly to reduce indoor pollutants and flame retardants found in dust.
- Be cautious with scented candles, sprays, and synthetic air fresheners.
- With children: Wash new toys and clothes before use. Choose wooden toys, organic cotton, and avoid plastic teethers or soft plastic toys.
- Replace items gradually. You don’t need to throw everything out overnight, just start with the products you use most often, especially those applied to large areas of skin or used on children.
Final Thoughts: You Deserve to Know
Endocrine-disrupting chemicals may be small, but their impact is enormous. They influence fertility, growth, cognition, and disease risk, often silently, and often too late to trace back.
At Kungul, we believe you deserve full transparency. You shouldn’t need a chemistry degree to understand what’s in your body lotion, lipstick, or sunscreen. That’s why we’re here to help you navigate the shelves, scan smarter, and feel confident in your choices.
Because when you protect your hormones, you protect your future. Scan your personal care products with the free Kungul app.
