*Products marketed with implied or explicit public health claims, such as specific antibacterial “kill” claims, need to be registered with the EU ECHA and or US EPA under FIFRA as biocidal/pesticidal products or devices and are not currently permitted. Please familiarize yourself with the relevant regulations concerning permissible claims.

Challenge: Cell phones are a germ-magnet!

In general, smartphones are 10 times dirtier than a toilet seat. People use their phones everywhere, incl. the bathroom (88%) and the kitchen(89%). 25% of cell phone owners have never cleaned their phone. Phones are competing with money for the No. 1 spot of dirtiest things to touch!

Solution: HeiQ antimicrobial additives

HeiQ’s antimicrobial additives for coatings and master batches offer an extra degree of hygiene protection to help alleviate consumer concerns. For cell phones, the easiest way to give this protection to the whole product is by incorporation of the antimicrobial into the display glass coating or into the phone casing material.
