Common questions

What is biocide made of?


What is biocide made of?

Biocidal products are often composed of mixtures of one or more active substances together with co-formulants such as stabilisers, preservatives and colouring agents.

What is biocide chemistry?

Biocide is a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means. Biocides are divided into two types, oxidizing and nonoxidizing.

How do you make biocide?

In the method of producing biocides from an aqueous flow of process water, a water flow containing ions, such as halogens, which give rise to conductivity are conducted through an electrolysis cell in order to generate chemicals with biocidal performance.

Is biocide harmful to humans?

Biocides are used to control harmful and unwanted organisms and microorganisms. However, not only do they kill pathogens, they also kill non-pathogens, meaning they may also be dangerous for humans. Biocides pose a particular risk to pregnant women, unborn life, small children, or people with serious chronic illness.

What are biocides examples?

Biocides are used to suppress harmful organisms that can cause damage to natural or manufactured materials. These harmful organisms include pests and germs. Examples of biocidal products are insect repellents, disinfectants and industrial chemicals like anti-fouling paints for ships and material preservatives.

What is the difference between biocide and pesticide?

Pesticides are used to combat undesirable organisms. The term pesticide comprises plant protection products and biocides. Biocides combat harmful organisms as well, but they are not strictly related to agriculture. Examples are disinfectants, rat-poison, wood preservatives and repellents.

Is an antibiotic a biocide?

Antibiotic is a more specific term that refers only to materials produced by an organism (esp. a microorganism) and that have biocidal or biostatic effect. So all biocides and antibiotics are antimicrobials. Not all antimicrobials and, as commonly used, no biocides are antibiotics.

Is biocide safe to use?

Which is an oxidizing agent in a biocide?

Composition: There are at least two main classes of biocide. On the one hand there are oxidizing agents such as chlorine dioxide and hydrogen peroxide. These happen to be the same chemicals that are also widely used for pulp bleaching.

How are biocides used in the real world?

To a silicon backbone, derivatives of the biocide were covalently attached. The mechanical properties as well as antifouling/fouling-release performance tests showed significant reduction in macro-fouling with sustained fouling-release characteristics for these coatings ( Choi et al., 2007 ).

Why are biocides used on the surface of coatings?

The presence of the biocide on the coating surface was expected to deter fouling organisms from attaching to the surface of the coating. Allyl glycidyl ether was used to provide crosslink functionalities.

How many biocides are needed for a biofilm?

It has been reported 117 that compared to the dosages applied to planktonic bacteria, 10 times or more is needed for sessile bacteria established as a biofilm. There can exist a variety of factors that would render biocide ineffective. These factors will be leading into the application of biocide dosages much higher than necessary.
