Although there are various anti bacterial makeup brushes, such as makeup brushes with Charcoal fibers. They can only kill some bacterial within certain period. After some period, they will lose such effect, also they can not kill all bacterial. As a professional makeup brush factory, Kingyin want to develop a kind of synthetic hair that can be permanent anti bacterial and can kill all kinds of bacterial.
Since last year, under the support of a USA/France BioShield company, Kingyin have put immense manpower, material and financial resources into such develop/research. After continuous sampling and testing in USA, Switzerland and France laboratories , we finally reach a significant result: our makeup bush samples showed 99.9999% reduction against Escherichia coli,Staphylococcus aureus, Pseudomonas aeruginosa after one hour contact time. All these bacterial are the strongest bacterial to be killed. And most important, no matter how many times to be washed, it is non-leaching.
Any interest to have your permanent anti bacterial makeup brushes, please feel free to contact us, we can send you test reports.
