Textile (allergic) contact dermatitis

Synthetic-fibre & disperse-dye safe

Zero synthetic content, for the specific, diagnosed allergy to disperse dyes and resin finishes used almost exclusively on polyester and nylon.

• Disperse dyes (used to colour polyester and nylon) and formaldehyde-resin 'easy-care' finishes are among the most common causes of diagnosed textile contact allergy, and they're not used on natural or regenerated-cellulosic fibres.
• Unlike eczema, this isn't about softness: wool, cotton, linen, silk and TENCEL are all fine here, because the allergen is the synthetic-fibre dye/finish, not the fibre's texture.
• The rule is strict, zero percent synthetic content, including recycled polyester/nylon, since the allergen is chemical, not about virgin-vs-recycled sourcing.

Sources: Contact Dermatitis (clinical literature) (identifies disperse dyes as a leading textile allergen, near-exclusively on polyester/nylon); American Contact Dermatitis Society (lists formaldehyde-resin finishes (permanent-press/easy-care) as a recognised textile allergen).

This is general information, not medical advice.We filter by disclosed fibre composition only, we can't see dye or finish chemistry, and everyone's skin is different. If you have a diagnosed condition or allergy, please check with your dermatologist or GP, especially before switching fabrics for a first time.
