Properties of Ideal Disinfectant
An ideal disinfectant or antiseptic has the following
characteristics:
1.
Ideally, the disinfectant should have a wide spectrum of
antimicrobial activity. It must be effective against a wide variety of
infectious agents (Gram-positive and Gram-negative bacteria, acid-fast bacteria,
bacterial endospores, fungi, and viruses) at high dilutions.
2.
It should act in the presence of organic matter.
3.
It should not be toxic to human or corrosive. In prac-tice, this
balance between effectiveness and low toxicity for animals is hard to achieve.
Some chemicals are used despite their low effectiveness, because they are
relatively nontoxic.
4.
It should be stable upon storage and should not undergo any
chemical change.
5.
It should be odorless or with a pleasant odor.
6.
It should be soluble in water and lipids for penetration into
microorganisms.
7.
It should be effective in acidic as well as in alkaline media.
8.
It should have speedy action.
9.
If possible, it should be relatively inexpensive.
