Arch Chemicals Secures EPA Registration For Purista

Arch Chemicals Inc., Norwalk, Conn.,
plans to launch the Purista® brand name to the US apparel and home textiles market — a result of
the Environmental Protection Agency’s (EPA’s) acceptance of a registration amendment to include the
use of Purista antimicrobial treatments on apparel and other textiles.

Purista treatments — currently used by more than 30 retailers on such items as linens,
towels, socks and suit linings — protect textiles from odor-causing bacteria.

“The EPA acceptance opens a major growth opportunity for the Purista brand in the sizable US
clothing and home textiles market,” said Peter Cowey, international business manager, textile
treatment business.
