Study Notes

Disinfection and Its Purpose

Disinfection is the process of eliminating or reducing microorganisms, excluding bacterial spores, from a surface or object.
The main difference between disinfection and sterilization is that disinfection reduces the number of microorganisms, whereas sterilization eliminates all microorganisms, including spores.

Chemical Disinfection

The purpose of chemical disinfection is to reduce the number of microorganisms on a surface or object using a chemical disinfectant.

Traditional Use of Disinfectants

Disinfectants are traditionally used to clean and disinfect surfaces, especially in healthcare settings, to reduce the transmission of infections.

Disinfectants and Antiseptics

A disinfectant can be used as an antiseptic, but not all antiseptics can be used as disinfectants, as antiseptics are used to prevent infection on living tissue.

Viricides

The purpose of a viricide is to inactivate or destroy viruses.

Bacteriostats

When a bacteriostat is removed from bacteria, the bacteria can resume growing and multiplying.

Disinfectants and Product Quality

The effect of a disinfectant on the quality of a product can be detrimental, as some disinfectants can alter the physical or chemical properties of the product.
