Optical Brighteners in Laundry
The question

Is Optical Brighteners in Laundry safe in laundry detergent?

CautionLaundry detergent

Fluorescent UV-absorbing chemicals that make whites appear brighter. They deposit on fabric and transfer to skin with wear — a concern given their potential to be skin sensitizers and endocrine disruptors.

What the research flags

  • Skin sensitization and contact allergy — particularly with sun exposure (photoallergy)
  • Potential endocrine disruption in some stilbene derivatives [inference]
  • Poor biodegradability — aquatic toxicity
  • Remain deposited on fabric through washing — continuous skin transfer

Regulatory
Some stilbene-based brighteners restricted in EU
