Caution

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

2,2'-methylenebis(6-bromo-4-chlorophenol) is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This halogenated bis-phenol compound is structurally related to bromochlorophene and used as an antimicrobial preservative. The EU Cosmetics Regulation (EC) No 1223/2009 Annex VI (list of preservatives) permits its use at a maximum concentration of 0.1%, though it is distinct from bromochlorophene which carries a different restriction code (V/37). Bis-phenol compounds raise concerns regarding endocrine-disrupting potential.

Known concerns

  • EU restricted preservative (0.1% max)
  • bis-phenol structural alert
  • potential endocrine concern
