As all Bioniq® Repair products are based on the principle of biomimetics, we never use harmful or questionable ingredients. Consequently, Bioniq® Repair-Toothpaste contains zero microplastics or nanoplastics. Our toothpastes do not contain tiny plastic beads made of polyethylene, otherwise known as microbeads, as abrasive particles. We only use mineral-based abrasives (silica and hydrated silica).
