H2COLOR PREMIUM technology, is a process where washing-off is improved with H2COLOR-AUX, but also high fastness to multiple washing with detergents containing peroxides is assured, by applying OXYPROTECT, a peroxide protecting agent, at the end of the dyeing and washing-off process.

Dyes are screened by ECOFOOT for their peroxide sensitivity, or a list of reactive dyes that have already been tested showing showing higher resistance to peroxides are recommended,  according to test ISO105C09. These dyes will reach 100% or near that mark, when submiitted to the test, after being treated with OXYPROTECT. Dyes are more sensitive to peroxides when applied at vey low liquor rations or by Pad-batch and those are the processes that need OXYPROTECT.
