Disperse Dyes (Synthetic Fabric)
The question

Is Disperse Dyes (Synthetic Fabric) safe in activewear?

CautionActivewear

Synthetic dyes used in polyester, nylon, and acetate fabrics that readily migrate onto skin due to poor fiber bonding. A leading cause of textile contact dermatitis and among the most common allergens in patch testing. Some disperse dyes release carcinogenic arylamines and have mutagenic potential.

What the research flags

  • Major cause of textile contact dermatitis — among top 10 patch-test allergens
  • Migrate onto skin from synthetic fabrics, especially under sweating conditions
  • Some dyes release carcinogenic arylamines under metabolic conditions
  • Mutagenic potential documented in in vitro testing

Regulatory
EU banned carcinogenic disperse dyes in textiles (REACH Annex XVII)
