HydroBlue® 90

HydroBlue® 90 will optimize your value chain

Sodium dithionite is a reducing agent, added in the yarn dyeing process with the indigo before denim fabric is made. Unique to BASF, the stable sodium dithionite content of HydroBlue® 90 products ensures an even steadier and more consistent dyeing effect on the yarn to minimize offspecification products along the value chain. It increases your efficiency, the safety of your workers, the quality of your products, and the satisfaction of your customers.

The quality of Hydrosulfite is one of the most important factors for denim manufacturers because faults in denim dyeing are difficult to detect until the very last moment – i.e. when the jeans have been produced. This means that denim quality largely depends on the quality of the Hydrosulfite reducing agent and indigo used. Manufacturers turning to BASF for consistent product quality has a direct bearing on production results. We are currently the only company in the world to produce Hydrosulfite in an improved formate process. This has helped us to achieve the highest consistent product quality and stability yet available, named HydroBlue® 90.
