Due  to  its  powerful wetting  properties,  it  is  recommended  for the wetting backing  of  mineral and crust  leathers.  About  0.2  -  0.5%  of  DECIWET -  DOS  on  the  weight  gives  excellent  results without the  presence  of  liquor  ammonia.  The  best  procedure  is to  run the  rinsed skins  in 500% float @ 60oC with  DECIWET  -  DOS  for  2 to  3  hrs.  And  leave  the  skin  overnight  in the bath.  The  skin  are  washed  next  day  and  are  ready  for  dyeing. 

 

It is  also useful  in the  stripping of  vegetable  tanned leathers before  mineral  tanning.  About  0.2%  of  DECIWET-DOS on the dry  weight of skin is  recommended.  The  best  way is  to  run the  rinsed leathers  with  the  detergent in the drum for  1 hour  and  leave  overnight in the  bath.  Next day  rinse  and proceed  with  stripping  with  additional alkalies  as required,  followed  by  through  washing.
