Active Ingredient Analyses

The efficacy of biocidal products is contingent upon their constituent active substances. These compounds are designed to eliminate, inactivate, or inhibit the proliferation of microorganisms.

What is an Active Substance?

An active substance is the active component of a biocidal product that acts against microorganisms or harmful organisms. This substance ensures that the product fulfills its primary function. Active substances can serve various purposes, such as bactericide (bacteria-killing), virucide (virus-killing), fungicide (fungus-killing), or algicide (algae-inhibiting).

What are the Functions of an Active Substance?

The primary functions of active substances in biocidal products include:

1. Eliminate or Inhibit Microorganisms: The active substance acts by destroying the cell wall of microorganisms, impairing their enzymatic activity, or damaging their DNA structures, thereby preventing their proliferation.
2. Disinfection: The active substance facilitates hygiene by eradicating microbial contamination on surfaces or within water systems. This function is of paramount importance, particularly within the healthcare and food industries.
3. Protection: Within certain biocidal products, the active substance safeguards the product or surface from microbial degradation. For instance, it is utilized in wood preservatives or paint additives.
4. Control of Harmful Organisms: Active substances are capable of controlling not only microorganisms but also insects, rodents, and other pests. These compounds exert their effect on the nervous system or are absorbed via the respiratory tract.
