KLAR® is the world’s first calcium-based bioceramic nicotine pouch, offering a nicotine sensation like nothing else. Here’s the lowdown on bioceramic innovation – and why it creates such a powerful nicotine experience you simply won’t find anywhere else.

From the world of medical technology

Wondering what a ‘bioceramic’ is? You’re not alone. Beyond a range of tried-and-tested medical applications such as implants, bone grafts and dental work, the world of bioceramics is not well known. 

In fact, bioceramics are advanced biocompatible materials, offering unique levels of strength and stability. They’re also excellent at releasing medicines in steady, smooth, controlled doses. Crucially, bioceramics are completely safe for human use. They don’t react in contact with our bodies, but stay inert – hence the term ‘biocompatible’. 

It starts with the nanostructure

All bioceramic materials have an adjustable nanostructure: a hard but porous structure with lots of tiny holes, where medicines – or other substances – can be loaded for release.

By fine-tuning the exact bioceramic material, the size of its nanostructure holes and the ingredients of the substance to be released, Emplicure – the innovators behind KLAR – were able to create a faster, more efficient nicotine delivery system.

The secret is SERATEK™

Each KLAR pouch contains SERATEK™, our patented bioceramic material. Naturally sourced and precision engineered in Emplicure’s bioceramic laboratory in Sweden, SERATEK is a calcium compound, coated in nicotine and blended with food-grade ingredients. SERATEK’s unique, fine-tuned properties are the secret to KLAR’s incredibly satisfying nicotine release.

The benefits of bioceramics

Powered by our proprietary SERATEK technology, KLAR delivers a 25% stronger kick with less nicotine*. SERATEK also provides a more stable delivery system, minimising impurities and giving you a smoother, more consistent sensation.

But that’s not all. KLAR pouches are noticeably smaller and softer than standard pouches. As soon as you pop in a KLAR pouch the SERATEK granules trigger instant hydration, resulting in a more comfortable feeling. 

The combined result of all this has to be felt to be believed.

Only KLAR delivers a noticeably bigger, smoother kick than equivalent standard pouches. Giving you a stronger, better nicotine experience overall, while reducing your nicotine intake by nearly half.

Why not try KLAR for yourself and feel the difference made by bioceramic technology?
