Frequently asked questions
What is sodium hypochlorite 20% and where is it used?

Sodium hypochlorite 20% (CAS 7681-52-9, NaClO) is a greenish-yellow homogeneous liquid containing a minimum of 190 g/dm³ active chlorine. It is used for the disinfection of drinking water networks and swimming pool water (Brand A - registered disinfectant), as an oxidising reagent in the vitamin industry (Brand B), for bleaching textile fabrics, in industrial water treatment and in wastewater disinfection.

What packaging is available and is it kept in stock?

It is supplied in rubber-lined steel tanks and in corrosion-resistant containers lined with rubber, polyethylene or fibreglass (UN 1791). It must be stored in special containers protected from sunlight. KORKİMYA ships ex-stock from its Istanbul warehouse and keeps local stock for fast delivery against import lead times.

Is it REACH-registered and is a safety data sheet provided?

Yes. The product is registered under the Turkish KKDIK / REACH framework and ships with a compliant safety data sheet (SDS). Because sodium hypochlorite reacts with acids and organic substances, the separate storage and ventilation instructions on the SDS must be followed.

How can I get a sample and a price quote?

KORKİMYA offers free samples and price quotes with invoicing. The active chlorine concentration (minimum 190 g/dm³) and a certificate of analysis (CoA) are shared on request. Specify the quantity you need and the delivery location to receive a quote.
