Company Swiftly Resolves Electric Toothbrush Mold Issue Through Material Innovation

Following customer feedback regarding mold growth on electric toothbrushes after a period of use, our company promptly established a dedicated technical team to conduct an in-depth analysis of the root causes of mold formation and to initiate systematic research focused on material formulation and anti-mold performance.

The project team screened various anti-mold additives and conducted multiple rounds of formulation optimization and anti-mold efficacy validation, taking into account matrix material compatibility and molding process characteristics. Through repeated testing and comparative analysis, a new material solution was successfully developed that combines excellent processability with highly effective anti-mold functionality. To verify the anti-mold performance of this solution, our company commissioned a third-party testing institution to conduct rigorous testing in accordance with the *GB 21551.2-2010* standard (*Antibacterial, Disinfection, and Purification Functions for Household and Similar Electrical Appliances – Special Requirements for Antibacterial Materials*). The test results demonstrated that the product's anti-mold performance fully complied with the standard requirements, effectively resolving the mold issue that concerned the customer.

This technical breakthrough not only helped eliminate a quality concern during product use for the customer but also further validated our company's technical expertise and rapid response capabilities in the fields of material development and anti-mold technology. Moving forward, our company will continue to be guided by customer needs, leveraging a rigorous R&D system and a professional technical team to provide customers with more reliable and comprehensive material solutions.
