Endocrine Disruptors in Fabrics: Why You Should Care!
A fabric label tells you whether a garment is made from cotton, polyester, linen, or a blend. But the story goes on.
At NoName, we have seen how dyeing, printing, finishing, and coatings can influence the chemical profile of a finished garment. This is why endocrine disruptors in fabrics matter for fashion startups.
Endocrine disruption happens when certain chemicals interfere with the body's natural hormone signals. They may mimic, block, or alter how hormones work.
This does not mean avoiding all synthetic fabrics or choosing natural fibres blindly. The smarter approach is to understand how the fabric is processed and whether the finished garment meets relevant safety and compliance standards.
For startups, responsible fabric sourcing can be an important step toward creating safer, more compliant, and more trustworthy products.
Quick Summary: Endocrine-Disruptors in Fabrics
Chemical | Where it may occur in textiles | Why brands should care |
PFAS | Water- and stain-resistant finishes | Some PFAS are associated with health concerns and are increasingly restricted |
Phthalates | Plasticised prints and PVC-related materials | Certain phthalates can interfere with hormonal and reproductive systems |
Bisphenols | Certain plastics, coatings and textile-related materials | Some have hormone-like activity |
Formaldehyde | Wrinkle-resistant and easy-care finishes | Can irritate and has carcinogenicity concerns |
Nonylphenol/NPEs | Textile processing and cleaning | Can have endocrine activity and environmental impacts |
What Is Endocrine Disruption and How Does It Happen?
Our bodies use hormones to regulate growth, metabolism, reproduction, and development.
Endocrine disruption occurs when an external chemical interferes with these hormone signals. It may mimic hormones, block them, or affect how the body produces and processes them. (NIEHS)
So, how does this relate to clothing?
Chemicals can enter textiles during dyeing, printing, finishing, coating, and other manufacturing processes. If certain substances remain in the finished garment and migrate from the material, they may contribute to exposure through skin contact.
Importantly, synthetic fabrics are not automatically unsafe, and natural fibres are not automatically chemical-free. What matters is the chemical profile of the finished garment and whether it meets relevant safety and compliance requirements.
For fashion startups, this makes chemical management an important part of fabric sourcing and clothing product development.
5 Textile Chemicals Fashion Brands Should Know
Endocrine-disruptors in fabrics can enter a garment through dyes, prints, finishes, coatings, or other textile processing.
They are not automatically linked to a particular fibre, so brands should consider the complete finished garment during fabric sourcing and clothing manufacturing.
1. PFAS
PFAS are chemicals used to provide water, oil, and stain resistance. They can be found in certain performance finishes and coatings.
Fabrics and clothing to watch: Waterproof polyester or nylon, rain jackets, outdoor clothing, performance wear, water-repellent fabrics, and stain-resistant garments.
Some PFAS have been associated with endocrine and other health concerns. This makes PFAS an important consideration in textile chemical compliance and fabric sourcing.
2. Phthalates
Phthalates are plasticisers used to make certain plastics flexible. In apparel, they can be associated with plasticised prints, PVC materials, and flexible coatings.
Fabrics and clothing to watch: Printed cotton T-shirts, graphic hoodies, sweatshirts, coated fabrics, PVC prints, rubberised graphics, and garments with plastic components.
Certain phthalates can interfere with hormonal and reproductive systems, making them relevant when assessing endocrine disruptors in fabrics.
3. Bisphenols, Including BPA
BPA is mainly associated with certain plastics and resins and is known for its potential hormone-like activity.
Fabrics and clothing to watch: Synthetic or recycled-material products, coated fabrics, plastic trims, and certain printed or coated garments.
However, polyester does not automatically mean it contains BPA. Its presence depends on the specific material and manufacturing process, which is why proper textile testing matters.
4. Formaldehyde
Formaldehyde can be used in certain textile finishes to provide wrinkle resistance, easy care, and dimensional stability.
Fabrics and clothing to watch: Wrinkle-resistant shirts, easy-care garments, treated cotton fabrics, uniforms, and other special-finish clothing.
Formaldehyde is mainly associated with irritation, sensitisation, and carcinogenicity concerns, rather than being classified simply as an endocrine disruptor.
5. Nonylphenol (NP) and NPEs
Nonylphenol and nonylphenol ethoxylates have been used in textile processing as cleaning, wetting, and processing agents.
Fabrics and clothing to watch: They can be relevant across cotton, polyester, nylon, blends, and other textiles because they may enter the supply chain during dyeing, washing, preparation, and finishing.
Their importance extends beyond the finished garment to chemical management and wastewater control during textile manufacturing.
For fashion startups, understanding these chemicals can make fabric sourcing and clothing product development more informed. The goal is not to avoid every synthetic fabric, but to understand how the fabric was processed and whether the finished garment meets appropriate textile safety and compliance standards.
How Exposure to Textile Chemicals Happens
Skin contact: Sweat, moisture, body heat, and friction can influence the migration of some chemical residues from clothing to the skin.
Textile processing: Chemicals can enter garments during dyeing, printing, finishing, coating, and other manufacturing processes.
Synthetic fabrics: Polyester, nylon, acrylic, and elastane are not automatically endocrine disruptors. The concern depends on the chemicals used during processing and the chemical profile of the finished garment.
For fashion startups, this makes fabric sourcing, textile testing, and chemical compliance important parts of responsible clothing manufacturing.
How Can Fashion Brands Reduce Chemical Risks?
For a fashion startup, textile chemical compliance can sound complicated. You do not need to become a textile chemistry expert or manage dozens of technical documents yourself.
The right clothing manufacturing partner can help you identify the checks that matter for your product, materials, and target market.
1. Start With the Right Manufacturer
Work with a clothing manufacturer experienced in fabric sourcing, textile testing, and international production. They can help evaluate suitable fabrics, finishes, prints, and testing requirements before production begins.
How NoName helps: At NoName, we work with fashion startups on fabric sourcing and product development, helping them select materials based on product requirements, quality expectations, and target markets.
2. Consider Natural Fibre Options
Organic cotton, linen, and merino wool can be suitable choices for brands looking to use plant-based or animal-based natural fibres. However, natural does not automatically mean chemical-free. Processing, dyeing, finishing, and other treatments still matter.
How NoName helps: Our fabric sourcing team helps brands compare material options based on fabric composition, performance, quality, and product requirements.
3. Check Relevant Certifications
Certifications such as OEKO-TEX® STANDARD 100 and GOTS (Global Organic Textile Standard) can provide additional assurance around textile safety and chemical management.
You do not need every certification for every garment. The right choice depends on your product, materials, and target market.
How NoName helps: We help brands understand which fabric certifications and testing requirements are relevant to their products, avoiding unnecessary specifications.
4. Be Careful With Special Finishes
If your garment needs to be waterproof, stain-resistant, wrinkle-free, antimicrobial, or anti-odour, find out what treatment is being used.
These finishes can involve additional chemicals, so they should be reviewed for suitability and compliance before approval.
How NoName helps: Our team works with brands on fabric finishes and performance requirements, helping them evaluate suitable options during product development and sourcing.
5. Check the Finished Garment
Chemical safety is not only about the base fabric. Your final garment may include:
Fabric + dye + print + finish + coating + trims
Testing and compliance checks should therefore consider the finished product, especially when selling in markets with strict requirements.
How NoName helps: At NoName, we look at the garment as a complete product, considering fabric, printing, finishing, trims, and construction, rather than evaluating the fabric alone.
6. Let Your Manufacturer Guide the Process
For startups, the easiest approach is to communicate your product requirements and target market early.
At NoName, we help fashion brands make these decisions during fabric sourcing and product development, so they do not have to navigate every technical specification alone.
Our approach: The goal is not more paperwork. It is making the right checks at the right stage so your garment is ready for production and the market you plan to sell in.
