About

Mibk is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

MIBK (CAS 108-10-1) is a ketone solvent listed as a VOC and subject to REACH restrictions for worker and consumer exposure. Under EU cosmetic regulation it functions as a solvent or denaturant, not primarily as a fragrance. SCCS has evaluated its exposure from cosmetic use and noted concerns about inhalation exposure in aerosolized products. It is not banned but requires specific product-type restrictions, particularly in sprays.

Known concerns

  • VOC classification and environmental concerns
  • Inhalation irritation risk in aerosolized products
  • REACH exposure restrictions
  • SCCS concern noted for spray applications
