• There is two chemicals in a glow stick,
  hydrogen peroxide, and diphenyl
  oxalate, plus a fluorescent dye. The
  chemicals encased in the plastic tube
  are the dye and the phenyl oxalate
  compound, while hydrogen peroxide
  sits in the glass vial.
• When the vial is broken, the
  chemicals mix and a reaction takes
  place. The phenol oxalate becomes
  oxidized, breaking up into two
  molecules of phenol and one of a
  peroxyacid ester.
• The peroxyacid decomposes quickly
  into C02 gas, exciting the dye that
  once relaxed, releases a photon of
  light.
Diphenyl Oxalate & Fluorescent Dye                                                    Peroxyacid Ester
                                                            Two molecules of Phenol

                                        Hydrogen Peroxide




                     Peroxyacid Ester
• The Dangers of glow stick is in the
  hydrogen peroxide and phenol (produced by
  a by-product). Phenol is toxic and can cause
  irritation when in contact with skin. Other
  side effects include swelling, burning, and
  in some extreme cases, nausea and
  vomiting. It’s advise to prevent ingestion of
  the substance.
