Formaldehyde
Toxins · VOC / IARC Group 1
High priority
Bottom line
Read Off Label rates Formaldehyde a HIGH avoidance priority (8.0/10) based on strong evidence of high chronic harm magnitude and high acute in salons exposure prevalence.
Lumber Liquidators 2015 scandal highlighted laminate flooring as a major source.
The intervention here is reducing exposure, not adding a compound.
What this is
Lumber Liquidators 2015 scandal highlighted laminate flooring as a major source. Keratin straightening treatments have been repeatedly associated with levels far exceeding salon worker safety thresholds. New-home off-gassing peaks in first 6-12 months. HEPA doesn't remove formaldehyde — activated carbon needed.
Mechanism
Reactive aldehyde; off-gasses from pressed-wood products (particleboard, MDF), laminate flooring, keratin hair treatments (Brazilian blowouts), some fabrics; indoor concentrations often 10x outdoor
Dose & route
Solid wood > engineered wood; avoid keratin/Brazilian treatments; ventilate after new furniture/flooring
