Question

Which if the following is an antiseptic
A) Lysol
B) Carbolic acid
C) Iodine
D) All

Answer 1

Hint:- Antiseptics are chemicals that kill or inhibit the growth of microorganisms on a surface or area. These are usually used in life concentrations, unlike the disinfectants. These are applied to the skin to prevent infections.

Complete answer:-
Carbolic acid is another name for phenol. It was introduced by Lister and is more commonly used to sterilize surgical instruments. Lysol as an antiseptic was introduced by Gustav Raupenstrauch to cope with the cholera epidemic. Lysol has cresol as a component. Lysol kills almost 99.9 percent of microorganisms. Lysol is more widely used as a disinfectant than an antiseptic.
Povidone-iodine is the commonest form of iodine used to disinfect the skin before any kind of surgery. It may also be used to sanitize the hands. Iodine can be used to disinfect minor wounds as well. Iodine is a good antiseptic and does not interfere with wound healing. It is effective against both gram-positive and negative bacilli. Iodine acts against bacteria, fungi, viruses, and even spores. Iodide is used as an antiseptic at a low concentration.
Thus, the right option is D.

Note:- Disinfectants are chemicals that are used for the same purpose as antiseptics but the main difference is that antiseptics are used on the skin and disinfectants are used to kill or inhibit the growth of microorganisms in a particular area. Examples of disinfectants are lime, Bordeaux mixture, DDT, etc. Disinfectants are stronger than antiseptics. They may harm the skin if applied to it.
