Frequently Asked Questions
What is sodium persulfate used for?
Sodium persulfate (CAS 7775-27-1, Na2S2O8) is a water-soluble oxidizing salt used as an initiator for emulsion and solution polymerization, as a strong oxidizing agent for chemical processing, and as an oxidative bleaching agent. It is also used as a depolarizer in battery manufacture. RawSource supplies it in bulk for these industrial applications.
Is sodium persulfate a bleach?
It functions as an oxidative bleaching agent, releasing active oxygen as an oxidizer rather than acting as a chlorine-based bleach. It is most commonly used as a polymerization initiator and chemical oxidant. Match the grade to your bleaching or oxidation process when ordering.
What is another name for sodium persulfate?
It is also called sodium peroxydisulfate or sodium peroxodisulfate, CAS 7775-27-1, formula Na2S2O8. Note that it is distinct from sodium bisulfate (a different acid salt). Verify the CAS on the CoA to avoid confusing the two.
What is the UN number and HS code for sodium persulfate?
It ships under UN 1505 and classifies under HS 2833.40 (peroxosulphates/persulphates). As an oxidizer it carries specific DOT shipping requirements; confirm classification and packaging against the current SDS before transport. RawSource provides the SDS with every shipment.
What is the cost of bulk sodium persulfate?
Bulk pricing depends on grade, order volume, and packaging (drums, totes, or IBCs). Request a current quote from RawSource with your target quantity and we will return delivered pricing plus a CoA and SDS.
What is the REACH and TSCA regulatory status of Sodium Persulfate (Sodium Persulphate)?
Sodium Persulfate (Sodium Persulphate) (CAS 7775-27-1) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 231-892-1).
