Answer 2

Answer:

Phenol was the first widely used antiseptic and disinfectant.

Explanation:

Phenol was one of the first antiseptics (carbolic acid). 0.2% solution of phenol is an antiseptic while 1 percent of its solution is a disinfectant. It is bacteriostatic at doses of 0.1%–1% and bactericidal/fungicidal at doses of 1%–2%.

Since phenol has a great ability to penetrate organic material, it is typically employed to disinfect machinery or organic components that need to be destroyed (eg, infected food and excreta). Due to its irritant, corrosive, and possible systemic toxicity properties, phenol is currently only used to cauterise infected locations, such as the infected umbilicus of infants. It is frequently used in cutaneous treatments for stings, bites, burns, etc. to alleviate itching and manage infections due to its local anaesthetic and antibacterial properties.

Hence, phenol was the first widely used antiseptic and disinfectant.
