HydroBlue® 90 LowPCF non food grade

HydroBlue® 90 is an improved formate-based hydrosulfite. It was formulated with a high degree of stability. HydroBlue® 90 offers an extra-long shelf life of two years. The smallest variation in terms of sodium dithionite content can affect dyeing results, such as ring dyeing, fastness, and color fixation. With the consistent sodium dithionite content in HydroBlue® 90, reliable dyeing results are achieved to reproduce the same shade. In addition, measurements show that HydroBlue® 90 contain significantly less SO2 than other hydrosulfites, resulting in a reduced odor. HydroBlue® 90 is also dustfree. HydroBlue® 90 is a GOTS approved additive by ECOCERT Greenlife as well as certified according to ZDHC Level 3 v3.1.
