Preparation and storage of antiseptic solutions: essential precautions

Antiseptics are disinfectants used for bodily care (disinfecting the skin, wounds and mucosa).

As paradoxical as it may seem, water-based antiseptic solutions may be contaminated by germs when being handled and may become germ cultures, especially in the case of the Pseudomonas aeruginosa (pyocyanic).

TO AVOID THE CONTAMINATION OF SOLUTIONS, ESSENTIAL PRECAUTIONS MUST BE TAKEN:

- Make all water-based dilutions either with:

· drinking water from a distribution network

· boiled water, previously filtered if necessary or

· water filtered through a well-maintained candle-shaped filter in good condition (brushed and disinfected or boiled once a week).

- Change all water-based solutions once a week at least.

To facilitate this, set one day of the week when all solutions are systematically changed.

- Prepare only small volumes at a time to avoid wastage or temptation to keep expired solutions.

- Never add fresh solution to a residue of out-dated solution (wash the bottles and allow them to dry before refilling them)

- Do not use a cork stopper

Indicate the name and concentration of products on all bottles.
