What Are Biofilms?

The best way to protect against biofilms is to prevent their formation.

Biofilms are intelligent and resistant.

Biofilms protect microorganisms from disinfection, allowing weakened pathogens to recover and grow. Removing a biofilm can require up to 1,000 times more disinfectant than normal, and in as little as 48 hours it can repopulate if not completely removed.

Why do Biofilms Matter?

Failure to eliminate and remove biofilms can create significant challenges for human health and industry. Biofilms, the natural habitat of microorganisms, impact daily life by harboring dangerous pathogens, bacteria and viruses. In addition, biofilms cause billions in economic damages through energy loss, equipment damage and product contamination, putting both brands and consumers at risk for foodborne illness outbreaks.

The Difference Sterilex

Sterilex's patented PerQuat technology was the first chemical formulation to receive EPA registrations with anti-biofilm claims for industrial and public health uses, including drinking water lines.

EPA Registration

Sterilex's PerQuat liquid disinfectants are the only ones on the market approved by the EPA to attack biofilm bacteria and remove biofilm completely.

Proprietary Chemicals

Dual active ingredients give Sterilex disinfectants their unique properties of efficacy against biofilms and provide a superior level of performance through multiple physical and chemical mechanisms of action.

Continued Protection

If not completely removed, biofilms can repopulate within 48 hours. Continued use of Sterilex's PerQuat products helps ensure that a system is completely clean by controlling biofilm, microbial seed dispersal and re-inoculation of the system.

Reaches niches of safeguarding

PerQuat foaming chemistry expands to reach all the impossible-to-reach places.

Biofilm Matrix Collapse

The chemical combination penetrates and collapses the EPS structure to break down and remove biofilms.

Kills Biofilm Bacteria

Kills up to 99.9999% of bacteria in biofilms.

Operational Benefits of Biofilm Control

Reduces risk of recall

Protects a food processing plant's assets: end product and equipment

Reduction of stoppages and retentions caused by product contamination

Reduces labor requirements by reducing scrubbing and rework

Reduces water by reducing rework

Prolongs shelf life by controlling spoilage organisms
