Main ingredient

Efficient free radical remover and reducing agent

Product Features

The hexavalent chromium in the leather is eliminated by the mechanism of reduction, and the oxidized radical existing between the leather fibers has a capturing function, which effectively inhibits the formation of hexavalent chromium. It can effectively reduce the content of hexavalent chromium in chrome tanning crust leather, and prevent the production of hexavalent chromium in the subsequent processing of chrome tanning crust leather, which helps the leather to maintain good ecological properties.
