REPLACEMENT SYNTANS -

Replacement syntans are leather chemicals used as synthetic substitutes of vegetable tanning agents for retanning of chrome tanned wet blue leather or E.I. tanned leathers.

 

Replacement syntans are based on the condensation products of phenol and naphthalene sulfonic acids.
  • Replacement syntans are favoured for retanning chrome leather to improve fullness and level dyeing thru uniform uptake and penetration of fatliquors and dyes which leads to improvement in buffing properties.
  • Replacement syntans reduce cationic charge of chrome leather.
  • Replacement syntans are used to produce white leathers.
  • Replacement syntans are also amphoteric with respect to their ionic charge and these can be used at different pH conditions exhibiting pH dependant tanning properties.
