About

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

Protokylol (4-[1-hydroxy-2-[(1-methyl-3-phenoxypropyl)amino]ethyl]benzene-1,2-diol) is a resorcinol derivative with beta-adrenergic agonist activity. As a sympathomimetic drug with structural similarity to catecholamines, it is subject to pharmaceutical regulation and is not permitted in EU cosmetic products. The compound lacks any cosmetic-compatible safety profile and carries cardiovascular stimulation risks.

Known concerns

  • Unauthorized pharmaceutical stimulant in cosmetics
  • Beta-adrenergic agonist — cardiovascular risk
  • No EU cosmetic authorization
