What is sodium persulphate?

With the formula Na2S2O8, sodium persulphate is a white solid soluble in water, non-hygroscopic and with a good shelf-life. It can also be called sodium peroxydisulphate. It’s very irritant to the eyes and may be toxic by skin absorption. This salt is typically synthesised via oxidation of sodium hydrogen sulphate.

2 NaHSO4 → Na2S2O8 H2

How is sodium persulphate used?

Common applications include curing of formaldehyde-based adhesives, and radical initiator in polymerisation reactions, such as the manufacture of acrylonitrile butadiene styrene. Other uses include as hair cosmetics or an ingredient in detergent, due to its bleach-like properties. It can also be used to replace ammonium persulphate in etching of printed circuit boards, or used for pickling of several metals including copper and others.

Finally, niche applications include:

  • Soil remediation
  • Manufacture of dyes
  • Modification of starch
  • Activator of bleach
  • Oxidising agent
  • Ion exchange agent
  • Water treatment

How safe is sodium persulphate?

This compound is not combustible, but it may enhance fire and explosion of other chemicals. Also, it may release irritating and corrosive gases in case of fire. Dangerously, it may explode if in contact with combustible or reducing compounds. Risks of exposure include redness and pain if in contact with skin and eyes, difficulties breathing if inhaled and nausea and vomiting if ingested.
