Clothing is more than just fabric and fashion—it touches your body thousands of hours a year. Yet, few consumers realise that common chemicals like BPA (Bisphenol A) frequently lurk in our shirts, socks, and even underwear.
How much BPA is in textiles? How much gets absorbed through skin? And what can you do to avoid it?
In this deep dive, you’ll discover:
-
Where BPA is hiding in your wardrobe—and why it ends up there
-
What science says about your potential exposure and health effects
-
Regulatory benchmarks and why they may not be enough
-
Practical strategies to remove BPA from your wardrobe and protection from future contamination
BPA in Clothing: How It Gets There
Though most associated with plastic bottles and food can linings, BPA also appears in the fashion industry, especially in polyester, polyester blends, and coated activewear.
-
Textile Manufacturing: BPA often acts as a dye-fixing agent, adhesive, or an anti-static coating.
-
Synthetic Fabric Additives: Materials like polyester and spandex may contain BPA to boost durability, moisture management, and color retention.
-
Fast Fashion & Sportswear: A 2021 CDC-style audit revealed polyester-spandex socks and sports bras from major brands like Adidas, Hanes, and Nike contained BPA at up to 19 times California’s legal limit.
That’s alarming, especially when these items are worn against the skin and often in sweaty, warm conditions.
How Much BPA Are You Wearing? And Why It Matters
Several landmark studies have shed light on BPA levels in textiles and their impact:
-
A recent analysis of 57 fabric samples found BPA in concentrations ranging from <50 ng/g to over 600 ng/g, with recycled fabrics containing nearly twice as much BPA as conventional ones.
-
Wear tests simulating sweaty skin indicated that exposure could exceed EFSA’s tolerable daily intake of 0.2 ng/kg bw/day, especially when wearing wet or humid clothes.
-
An earlier study found 82% of everyday garments—from socks to baby clothes—had BPA or BPS, with average BPA levels up to 13,000 ng/g.
These aren’t trace contaminants—they’re pervasive in our daily clothing.
Health Impacts: What BPA Does to Your Body
BPA is a well-known endocrine-disrupting chemical. Its structure allows it to mimic estrogen, triggering effects such as:
-
Reproductive harm in both men and women (e.g., fertility issues, PCOS).
-
Links to increased risk of breast, prostate, kidney, and testicular cancers.
-
Neurodevelopmental impacts: anxiety, depression, ADHD, and delayed puberty in children.
-
Metabolic health issues: obesity, type 2 diabetes, and heart disease
-
Thyroid dysfunction, asthma risks, and immune suppression
And it doesn’t end there. Studies also link BPA to epigenetic changes and breast tissue alterations that may lead to cancer.
Why Skin Contact Changes Everything
You’re not just wearing BPA—you’re absorbing it. Factors that amplify risk include:
-
Direct dermal transfer, especially with warm, moist skin and tight garments
-
High exposure in infants and toddlers to polyester-coated baby clothes
-
Lower metabolic clearance via the skin compared to oral exposure
This raises significant concern—and should prompt conscious changes in wardrobe and washing habits.
What You Can Do: 7 Actions to Reduce BPA Exposure
A. Audit Your Wardrobe
Look for polyester, spandex, and treated athletic wear that may contain BPA.
B. Choose Natural & Certified Fabrics
Go for OEKO-TEX® Standard 100, GOTS, or bluesign® certified items that prohibit BPA.
C. Prioritise Reputable Brands
Support companies that test for BPA and publish clean safety data, such as Orbasics and other certified eco brands.
D. Rinse & Wash Before Wearing
Studies show washing can reduce BPA by up to 50%. Always pre-wash new clothing.
E. Avoid Synthetic Baby Clothes
Prefer organic cotton over polyester blends for infants and children to lower exposure risk.
F. Advocate for Disclosure
Demand brands test for and label BPA—or phase it out. Use petitions and social media to push for better industry standards.
G. Support Stronger Regulation
Pressure agencies worldwide to regulate BPA in textiles and enforce safe standards, keeping companies accountable.
The Takeaway: Clothes Should Heal Carefully
BPA in clothing isn’t a fringe threat—it’s a pervasive risk that touches us every single day. When textiles are loaded with chemicals, our skin becomes an unwitting passageway for exposure.
But the good news? You have the power to change it. By choosing natural, certified fabrics and supporting brands that test and disclose, you help safeguard your body and demand better standards.
The next time you buy clothes, pause and ask: What am I really wearing—and will it wear me down?
