EISAI ANNOUNCES LAUNCH OF CRYSTAL VEIL® MASK BOKIN 24, A NEW 24-HOUR MASK SPRAY THAT CONTAINS THE LONG-ACTING ANTIMICROBIAL AGENT ETAK®Helps Prevent the Adherence of Viruses and Bacteria to Face Masks

(Production of CRYSTAL VEIL® MASK BOKIN 24 ended as of January 2016.)

Eisai Co., Ltd. (Headquarters: Tokyo, President & CEO: Haruo Naito, “Eisai”) announced today that it will launch the new mask spray Crystal Veil® Bokin 24 (classified as miscellaneous goods) on Tuesday, September 18. Crystal Veil Mask Bokin 24, which contains the long-acting antimicrobial agent Etak®, is sprayed onto face masks prior to use, making it difficult for viruses and bacteria to adhere to the mask surface for a prolonged period of time.

Crystal Veil Mask Bokin 24 is designed to ensure that face masks remain clean and hygienic. While people that wear face masks often worry about whether or not the masks are still hygienic after prolonged use, spraying Crystal Veil Mask Bokin 24 on the mask prior to use provides a sustained antimicrobial effect. Spraying the mask just once prevents viruses and bacteria from adhering to the mask surface for a period of approximately 24 hours.

Etak, the main ingredient in the new spray, is a long-acting antimicrobial agent containing both antimicrobial and adhesive substances that was developed by Professor Hiroki Nikawa of the Department of Oral Health Engineering at Hiroshima University's Graduate School of Biomedical Sciences. The adhesive ingredient in Etak chemically binds to sprayed surfaces, thereby ensuring that the bactericidal ingredient provides a prolonged antimicrobial effect even after the agent dries.

Crystal Veil Mask Bokin 24 helps ensure that face masks remain clean and hygienic for a prolonged period of time through the simple action of spraying, thereby providing consumers who wear them with a sense of reassurance. Eisai remains committed to ensuring the delivery of products that satisfy the diversified needs of consumers and to making further contributions to increase the benefits provided to them.
