Using Alcohol as a Disinfectant and Antiseptic

1. Using Alcohol as a Disinfectant and Antiseptic

This lesson will discuss how alcohol can be used as a disinfectant and antiseptic but not a sterilant. We'll also talk about what it kills and doesn't kill and why ethyl alcohol and isopropyl alcohol are the two most commonly used alcohol-based disinfectants.

What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages

2. What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages

We will explore a disinfectant known as phenol. We'll cover what its mechanism of action is, what it can and cannot kill, its advantages and disadvantages and its involvement in enzyme systems.

Chlorine and Quaternary Ammonium Compounds: Advantages and Disadvantages

3. Chlorine and Quaternary Ammonium Compounds: Advantages and Disadvantages

This lesson covers the very common and well-known disinfectants chlorine and quaternary ammonium. We will talk about their advantages, disadvantages, and uses in addition to the types of microbes they can kill.

What Are Peroxide Antiseptics? - Definition, Types & Uses

4. What Are Peroxide Antiseptics? - Definition, Types & Uses

We will discuss chemical substances known as peroxides. You'll learn about hydrogen peroxide and peracetic acid as well as the way by which they kill microbes and whether or not they are used as a sterilant, disinfectant, or antiseptic.

What is Formaldehyde? - Definition, Uses & Structures

5. What is Formaldehyde? - Definition, Uses & Structures

Do you remember that liquid in a jar that you used in biology class to preserve the frog you dissected? That liquid contains a substance known as formaldehyde. In this lesson, we will learn more about formaldehyde, its structure and its other uses.

What Is Ethylene Oxide? - Uses, Safety & Technology

6. What Is Ethylene Oxide? - Uses, Safety & Technology

This lesson will discuss how a type of gas, called ethylene oxide, can sterilize equipment. We'll talk about the way by which it does this, what its advantages are, as well as the dangers it poses to human health if used improperly.

Chlorhexidine, Iodine & Silver: Uses and Modes of Action

7. Chlorhexidine, Iodine & Silver: Uses and Modes of Action

This lesson will discuss four commonly heard of chemical antiseptics: namely, iodine and iodophors, silver nitrate, silver sulfadiazine, and chlorhexidine, and it will cover the ways by which they kill microbes.
