The majority of  producers and sellers of leather items require now that those items do not contain any amount of Cr  VI.

The use of  many types of Fatliqours generates by ageing Cr VI  ,therefore not detectable immediately after its production.

TRUPOFIX SA2 can prevent the oxidation of Cr III to Cr  VI.

This can be performed by addition of    TRUPOFIX SA2 to the final stage of leather wet treatment or even sprayed on dry leather flesh side.

Moreover leather exceeding  the amount of  3 ppm of Cr VI can be sprayed with a solution of  TRUPOFIX SA2 in order to lower  Cr VI to the prescript content.
