At HertzandHealth, we’re digging into the hidden chemicals in conventional underwear and how choosing eco alternatives can support your health and the planet.
Why Eco Chemical-Free Underwear Is Better for Your Body and the Planet
At HertzandHealth, we believe conscious choices, especially the ones closest to your skin, can make a big impact. Underwear is worn daily, against some of the most sensitive areas of the body, yet it’s often made with synthetic fabrics, harsh chemicals, and questionable manufacturing practices.
This article is part of our ongoing research into low-tox living, and while we don’t endorse specific brands, we’re here to share helpful information so you can make empowered choices. As always, we encourage you to do your own research too.
1. Why It Matters: Skin Contact + Chemical Exposure

Many conventional underwear options are made using:
- Synthetic fabrics (like polyester and nylon)
- Chemical treatments including:
- Formaldehyde (for wrinkle resistance)
- Azo dyes (some are carcinogenic)
- Flame retardants
- PFAS (used for water and stain resistance)
- These substances can absorb into the skin over time and may contribute to:
- Hormonal imbalances
- Skin irritation
- Long-term toxic load
2. Benefits of Eco & Chemical-Free Underwear
Switching to underwear made from natural, untreated fabrics can support your:
- ✅ Skin health (less irritation, fewer rashes)
- ✅ Vaginal/genital health (better airflow, fewer infections)
- ✅ Immune system (lower toxic exposure)
- ✅ Environmental impact (lower water use, less pollution)
3. What to Look For When Shopping
Instead of listing brands, here are independent criteria you can look for:
Look For
- GOTS-certified organic cotton
- OEKO-TEX® certification
- Plant -based fibers
- Low-impact or natural dyes
- Minimal packaging & ethical sourcing
Look For Why It’s Good
- Free from pesticides, ethically grown
- No harmful chemicals used in the production
- Like bamboo, hemp or unbleached cotton
- Reduce chemical exposure
- Better for the planet and people
4. Start Small—Every Switch Matters
You don’t need to overhaul your entire underwear drawer overnight. Try:
- Swapping in 1-2 new pairs made from natural fibre’s
- Reading labels more carefully
- Supporting brands that share ingredient and sourcing transparency
