Sodium Dichloroisocyanurate (NaDCC) is a chlorine-releasing compound used for disinfection of medical devices, instruments, linen, floors, and surfaces, with specific preparations and precautions for different applications.
- Sodium dichloroisocyanurate (NaDCC) is a disinfectant and chlorine-releasing compound. - It is used for disinfection of medical devices, instruments, linen, floors, and surfaces. - NaDCC comes in effervescent tablets, granules, and powder. - The recommended concentration for disinfection solutions is 0.1% active chlorine (1000 ppm). - Precautions include preparing solutions with cold water, avoiding contact with acid solutions and detergents, and protecting stainless steel instruments from corrosion. - NaDCC can be used for wound antisepsis, but only if the formulation is intended for this purpose. - Some formulations can be used for disinfecting drinking water, following the manufacturer's instructions. - NaDCC is also known as sodium troclosene and sodium dichloro-s-triazinetrione. - It should be stored in an airtight container, protected from light, heat, and humidity.

Indications
- Disinfection of medical devices, instruments, linen, floors and surfaces
Forms and strengths
- 1.67 g NaDCC effervescent tablet, releasing 1 g active chlorine when dissolved in water.
Also comes in different strengths and in granules and powder.
Preparation and use
Pre-disinfection of soiled instruments
- 0.1% active chlorine solution (1000 ppm): 1 tablet of 1 g active chlorine per litre
Immediately after use, soak instruments for 15 minutes, then clean instruments.
Disinfection of clean instruments
- 0.1% active chlorine solution (1000 ppm): 1 tablet of 1 g active chlorine per litre
Soak previously cleaned instruments for 20 minutes, rinse thoroughly and dry.
Disinfection of linen
- 0.1% active chlorine solution (1000 ppm): 1 tablet of 1 g active chlorine per litre
Soak for 15 minutes, rinse thoroughly (at least 3 times).
General disinfection (surfaces, floors, sinks, equipment, etc.)
See Chlorine-releasing compounds and Antiseptics and disinfectants, Part two.
Precautions
- Prepare solutions with cold water, in non metallic containers.
- NaDCC can corrode metal. The risk is limited for good quality stainless steel instruments if concentration, contact time (20 minutes maximum) and thorough rinsing recommendations are respected.
- For disinfection of linen: use only for white cotton or linen (risk of discolouration).
- Do not expose the product to flames. Do not incinerate.
- DO NOT SWALLOW. Do not store NaDCC tablets near oral tablets.
- Avoid inhaling vapours and dust when opening or handling the containers.
- Do not mix with acid solutions such as urine, etc. (release of toxic chlorine gas) and detergents.
Remarks
- NaDCC may be used for wound antisepsis but only if the formulation is intended for this purpose: 0.1% active chlorine solution (1000 ppm): 1 tablet of 1 g active chlorine per litre. For prolonged use, protect the healthy skin around the wound with vaseline.
Caution: some formulations used for disinfecting floors contain additives (detergents, colouring, etc.) and cannot be used on wounds. Check label or leaflet.
- Some formulations can be used for the disinfection of drinking water (Aquatabs®, etc.). Follow manufacturer's instructions.
- NaDCC is also called sodium troclosene, sodium dichloro-s-triazinetrione.
Storage
– In airtight container, protected from light, heat and humidity, in a well ventilated room
