- Dark violet crystals to be dissolved
- Tablets to be dissolved: they come in various dosages 0.25 g, 0.5 g and 1 g.
- Dilute 0.01% (100 mg to 1 litre of water).
- The concentration must be precise:
• if it is too concentrated, it is caustic
• if it is too diluted, it is ineffective.
A balance is necessary to obtain the right concentration from the crystals.
- Handle dry product or concentrated solutions with care (skin burns and risk of explosion if brought into contact with an easily oxidisable product).

- Repeated application dries the skin.
- This product offers no particular advantages other than that it is not very costly.
- Its use is counter-indicated because of the constant errors made in diluting from crystals and the risks of the tablets being swallowed.
