About

A brominated ester compound with significant hazard warnings including skin sensitization and reproductive toxicity concerns, warranting careful handling.

Benzyl 2,4-Dibromobutanoate is a brominated carboxylic acid ester carrying multiple GHS hazard statements: H315 (skin irritation), H317 (skin sensitization), H361f (reproductive toxicity), H319 (eye irritation), H400/H410 (aquatic toxicity), and H335 (respiratory irritation). The presence of two bromine atoms on the butanoate chain raises concern under EU REACH and Cosmetic Regulation frameworks. While not currently listed in EU restriction annexes, the hazard profile suggests this substance would face scrutiny if used in cosmetic formulations, particularly given the reproductive toxicity flag. EU Annex II would likely ban substances with H361f classification if intended for cosmetic use.

Known concerns

  • H361f - suspected reproductive toxicity
  • H317 - may cause allergic skin reaction
  • H400/H410 - very toxic to aquatic life
  • H315/H319/H335 - irritant to skin, eyes, and respiratory tract
  • Not listed in EU cosmetic annexes but hazard profile is highly concerning
