Cotton On Women All Day Crew Tee
Lower concern. Basic cotton tee with no known PFAS treatments.
All Day Crew Tee is primarily cotton without disclosed water-repellent, stain-resistant, or antimicrobial finishes typical of PFAS-treated apparel. Cotton On makes no PFAS claims; standard wash-and-wear cotton poses minimal PFAS risk.

What Cotton On Women All Day Crew Tee is made of, ingredients and materials
This is a 100% cotton crew neck tee. Cotton fiber itself is a natural cellulose material with no inherent chemical hazards at the fiber level. Hazard risk in cotton apparel comes from dyes, finishing resins, and treatments applied during manufacturing. No specific coatings or water-repellent finishes are named for this product, which lowers concern for persistent chemical residues.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Azo dyes and synthetic dyes
Cotton apparel typically uses standard industrial azo dyes. No known issues or recalls are on record for Cotton On basics, but composition of dyes is not disclosed. Azo dyes can release carcinogenic amines under certain conditions (heavy metal catalysts, extreme heat, or degradation); risk is low for normal wear and washing.
Lead
Trace heavy metals can remain as contaminants in synthetic dyes or from dyebath residues. No recalls or test results are on record for this product. Risk is low with standard industrial oversight, but not guaranteed without third-party testing or certification.
Source, ATSDR ↗Microfiber shedding and environmental persistence
Cotton sheds natural fibers during washing, which biodegrade in standard sewage and landfill conditions. Risk to wearer is negligible; concern is primarily environmental. Frequent washing and mechanical stress (dryer use, pilling) increase shedding; line drying reduces it.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No specific finishing treatments are named for this crew tee. If formaldehyde-based resins were used, they are typically applied in small amounts to cotton basics and off-gas significantly during the first few washes; pre-washing mitigates exposure.
Source, ATSDR ↗Antimony in polyester
This product is 100% cotton, so antimony (a catalyst used in polyester production) is not a concern.
The full breakdown
The brand's record and disclosure
Cotton On is a large, mainstream fast-fashion retailer with no widely publicized chemical safety disclosures or certifications (such as GOTS or OEKO-TEX) on record for this line. The brand's PFAS stance is silent, meaning no public commitment to restrict or disclose PFAS use. No major chemical safety recalls or controversies are documented for Cotton On basics in recent years, but transparency on manufacturing chemicals and supplier audits is not evident.
How it compares in its category
Basic cotton crew tees are among the lowest-risk apparel items because they involve minimal chemical processing compared to performance fabrics, denim, or colored synthetics. Cotton On's price point and fast-fashion model suggest standard dyeing and finishing, not premium or certified processes. A certified organic cotton tee or GOTS-certified equivalent would offer more assurance of restricted chemical use, but this product sits at typical mainstream standards.
If you buy it
Wash before wearing to reduce loose dyes and any residual finishing chemicals. Launder in cold water and line dry to extend durability and reduce microfiber shedding. Watch for color bleeding in the first few washes, particularly if dyed darker. Replace when fabric thins, seams fray, or pilling becomes excessive; early retirement is preferable to shedding microfibers into the wash cycle.
