What is an Antimicrobial Additive?


What is an Antimicrobial Additive?

An antimicrobial additive is a technological innovation designed to resist, inhibit, and prevent the growth of microbes, such as bacteria and mould. BioCote® has harnessed the properties of antimicrobial materials, known as ‘active ingredients,’ and formulated them into a range of antimicrobial additives.

Integrated into a surface during the manufacturing process, an additive will encompass a specific antimicrobial active, such as silver ion technology, and can be formulated into a concentrated powder, liquid suspension or masterbatch pellet depending on the target material and manufacturing process. Once infused into a product, the antimicrobial additive will work continuously to make a product more hygienic, minimising the potential for cross-contamination and extending a product’s functional lifetime.

Examples of Antimicrobial Additives

Silver Ion Technology: Silver ions possess potent antimicrobial properties, disrupting microbial cell membranes and interfering with essential cellular functions. It is widely used in medical equipment, textiles, plastics, and coatings, silver ion technology provides continuous protection against a broad spectrum of microorganisms.

Copper-Based Additives: Copper ions exhibit antimicrobial efficacy by compromising microbial cell walls and interfering with cellular processes. Found in surfaces, fabrics, and coatings, copper-based additives contribute to reducing the microbial spread.

Quaternary Ammonium Compounds (QACs): QACs disrupt microbial cell membranes, leading to cell leakage and eventual microbial inactivation. Commonly used in disinfectants, sanitisers, and coatings, QACs provide reliable antimicrobial protection in various environments.

Benefits of BioCote® Additives

BioCote® antimicrobial additives work 24 hours a day, 7 days a week to reduce the levels of microbes by up to 99.99%, reassuring end-users that their product is permanently protected and therefore less likely to harbour damaging microorganisms.

The technology’s ability to minimise microbial colonisation also reduces the potential for staining and unpleasant odours, meaning a protected product will stay fresher for longer and have an increased functional life cycle – offering a significant cost benefit to the consumer. BioCote® silver ion additives will not wear off or leach from the surface they are manufactured into, making them safe for use in a variety of products such as baby toys, kitchen appliances and bathroom accessories.
