Biocote
All of the plastic components in our Series 2 range are infused with BioCote antimicrobial additives. This means those materials are permanently protected from a wide spectrum of microbes, including bacteria, mould and fungi.
It also makes the coating resistant to surface staining, bad odours and material degradation.
Chilly’s bottles with BioCote® technology reduces the growth of bacteria and mould on the surface—supporting a more hygienic product over time.

Thanks to BioCote® antimicrobial protection, Chilly’s bottles are designed to stay fresher and cleaner for longer, even with everyday use.
WHAT IS ANTIMICROBIAL TECHNOLOGY?
BioCote® antimicrobial technology is designed to help reduce the growth of microbes—like bacteria and mould—on surfaces, including those used in Chilly’s bottles. The technology is added during manufacturing, helping your bottle stay cleaner and fresher for longer, wherever you go.
WHAT ARE THE ADVANTAGES AND BENEFITS OF BIOCOTE® ANTIMICROBIAL TECHNOLOGY IN CHILLY’S BOTTLES?
By helping to minimise the growth of microbes like bacteria, mould, and odour-causing organisms, BioCote® technology keeps your Chilly’s bottle looking fresher and more durable. It helps maintain the condition of your bottle over time because it reduces microbes that cause staining, discolouration, and unpleasant odours.
HOW LONG DOES BIOCOTE® LAST IN CHILLY’S BOTTLES?
BioCote® antimicrobial technology remains effective throughout the lifespan of your Chilly’s bottle, providing long-lasting protection. Unlike other antimicrobial treatments that wear off or degrade over time, BioCote® remains effective for up to 50 years, ensuring a hygienic and clean bottle for years to come.
WHAT SORT OF BACTERIA DOES BIOCOTE® ANTIMICROBIAL TECHNOLOGY WORK AGAINST IN CHILLY’S BOTTLES?
BioCote® antimicrobial technology has been proven effective against a wide range of bacteria, including those commonly found in drinking water, such as E. coli, Salmonella, Legionella, and Campylobacter. This protection helps to maintain a cleaner material inside your Chilly’s bottle, giving you peace of mind with every sip.
IS BIOCOTE® SAFE IN CHILLY’S BOTTLES?
Absolutely! BioCote® technology is non-leaching and uses minimal quantities, making it both safe and effective for all users. It's HACCP-approved and meets the highest standards for safety and hygiene, ensuring that your Chilly’s bottle remains free from unwanted microbes without compromising your health.
ARE CHILLY'S BOTTLES RECYCLABLE, AND WHAT HAPPENS TO THE BIOCOTE® TECHNOLOGY DURING RECYCLING?
Yes, Chilly's Series 2 bottles are designed with sustainability in mind. The main body and collar of the bottle are recyclable. The Take Back scheme allows customers to send back their used bottles for recycling.
Regarding BioCote® antimicrobial technology, it is integrated into the bottle's material and does not affect the product's recyclability. The technology remains embedded within the recycled material, continuing to provide antimicrobial properties even after the product has been processed and repurposed.
Please note: While BioCote® technology offers lasting antimicrobial protection, it doesn't replace regular cleaning. To keep your Chilly's bottle in optimal condition, we recommend washing it as usual.
