Biocides are classified as antimicrobial agents that encompass a broad spectrum of activity, specifically designed to kill all types of microorganisms. This classification is due to their effectiveness in a variety of applications including sanitation, preservation, and disinfection. Unlike substances that merely reduce or inhibit the growth of microorganisms, biocides actively destroy them, making them critical in environments requiring stringent hygiene standards.

The focus on biocides killing all microorganisms distinguishes them from agents that only reduce their levels or inhibit their growth. This aspect is especially important in settings such as hospitals or laboratories, where the complete eradication of pathogens is essential to ensure safety. Understanding the nature of biocides and their role in public health and safety highlights the importance of choosing the right microbial control measure for specific situations.
