Indications
Cleaning and disinfection of:
- skin and mucous membranes
- wounds
- burns
- ulcers
- abscesss

Preparation
- Concentrated solution of 5 % chlorhexidine digluconate to be DILUTED before use. Check whether the supplied concentrated solution can be diluted with non-distilled, ordinary water (in this case, the solution must contain a cosolvent).
- There are solutions of 20 % chlorhexidine, but they contain generally no cosolvents and must therefore be DILUTED WITH DISTILLED WATER to avoid a possible precipitation of chlorhexidine.

Dilution
- Used in an aqueous solution of 0.05 % chlorhexidine = 10 ml of the 5 % solution in 1 litre of water.
- Use drinking water from the water mains or boiled water, filtered if necessary.

Products that generate CHLORINE (Calcium hypochlorite = HTH, Chlorinated lime, Bleach, Sodium dichloroisocyanurate or NaDCC)

Therapeutic action
- Strong disinfectants (generate active chlorine)

Indications
- Disinfection of objects, instruments, linen...
- Disinfection of floors, surfaces (tables, sinks...)

Preparation
- Calcium hypochlorite grains (HTH) ..+/-70 % active chlorine
- Chlorinated lime powder, bleaching powder+/- 25 % active chlorine
- Solutions of sodium hypochlorite (bleach, Milton(R):
· Bleach 12° chlorometrical degrees .. +/- 4 % active chlorine
· Bleach 15° chlorometrical degrees ...+/- 5 % active chlorine
· Concentrated bleach 48° chlorometrical degrees... +/- 15 % active chlorine
(to be diluted in 3/4 litre water to become bleach with 4 % active chlorine)

- Sodium dichloroisocyanurate or NaDCC:
· Powder ..60-65 % active chlorine
· Tablets (Javel solid(R)) 1.5 g active chlorine per tablet

The power of the disinfectants that generate chlorine is expressed in active chlorine (generally percentage in active chlorine).

The amount of active chlorine is sometimes expressed in chlorometrical degrees.
1° chlorometrical = approximately 0.3 % active chlorine

The amount of chlorine in diluted solutions is expressed in % or in ppm (parts per rnillion) of active chlorine (1 ppm = 1 mg/litre = 0.0001%).

Dilution
-The amount of active chlorine must always be checked on the packaging of the product to correct the dosage if necessary.
-In certain conditions, solutions with a stronger content of active chlorine can be made by adjusting the dosage.
-Always dilute in non-metal containers just before use.
-A deposit in HTH or chlorinate lime solutions is normal (use the upper part). -Prepare solution with clean water.


FIGURE

Precautions
-Handle the concentrated products with care (avoid jolts and exposure to high temperatures or flames).
-Avoid inhaling vapours and dust when opening or handling the containers.
- Do not mix with detergents.
-Do not bring the dry product, particularly calcium hypochlorite, in contact with organic materials (for example: corpses): risk of explosion.
-Disinfection of linen
Only suitable for cotton and linen (but risk of discolouration). Soak for maximum 15 minutes. Do not exceed 0.1% (1,000 ppm) of active chlorine. Rinse abundantly (at least 3 times) with clear water after soaking.
-Disinfection of instruments
To avoid corrosion, use only for stainless steel instruments. Do not use solution containing more than 0.1 % (1,000 ppm) of active chlorine frequently, do not leave in contact for more than 30 minutes, instruments and solution should be cold, rinse abundantly and dry after disinfection.
-NaDCC is less corrosive than solutions of calcium hypochlorite and bleach.

Remarks
-Chloramine T (sodium tosylchloramide) also produces chlorine (25 % active chlorine), but acts more slowly than the products described above. It is especially suitable as an antiseptic for infected wounds and mucous membranes because it is less irritating.
-Calcium hypochlorite, bleach and concentrated bleach can be used to prepare antiseptic solutions (DAKIN solution) if 1 teaspoon of sodium bicarbonate is added to the final solution (to neutralise the alkalinity).
· For wounds: solution of 0.1 % (1,000 ppm) active chlorine.
· For mucous membranes: solution of 0.05 % (500 ppm) active chlorine.

- Trichloro-isocyanuric acid containing 90 % of active chlorine is very similar to NaDCC, but its use is limited by poor solubility. It is mainly used for chlorination of pool water as pellets placed in a float.
-Storage:
· Store in air-tight containers: protectedfrom light and heat (and humidityfor solids).
· Chlorinated lime, bleach and concentrated bleach are difficult to keep (maximum a few months for the last two).
· Calcium hypochlorite is relatively easy to keep.
· NaDCC is much more stable.
