Our Borrebright products are stable and functional over a broad pH and temperature range, and are useful in leather tanning formulations. Adjusted to a pH between 3 and 5, they perform similarly to traditional vegetable tannins like mimosa and quebracho extracts.

Borrebright are light coloured biopolymers based on lignin, the natural binder of wood fibres in trees. They are highly compatible with natural synthanes and synthetic tanning agents.

Borrebright products compared to a standard lignosulfonate (at the far right).

Key benefits offered: 

  • High dispersant efficiency 
  • Cost-effective solutions 
  • Sustainable alternatives to synthetic tanning agents 
  • Improved buffering capabilities 
  • Improved soaking ability 
  • Low viscosity at high concentrations  

In addition to Borrebright, we offer a wide range of other lignosulfonates (calcium, sodium and ammonium) for this application. Our technical experts can help you select the right product according to your planned use, requirements and geographical location.
