TFL launches two reductive unhairing agents, able to replace sulphide

19 February 2019

Ecological leather processing starts in the Beamhouse with Hair-Save, Low Sulphide Unhairing. With the launch of PELLVIT LSG, and ERHAVIT LSU, TFL have successfully provided the leather industry with a cost-effective, ecological and sustainable system to facilitate hair-save unhairing for quality leathers.

Although in practice most tanners still run hair-burn processes with huge sulphide offers, hair-save systems are rapidly becoming the new industry standard. The main challenge for the tanneries is to remove the hair completely, with a sulphide offer of 1% or less, including a proper removal of hair-roots and fine-hair.

With ERHAVIT LSC & ERHAVIT LSR, TFL launches two new reductive unhairing agents, allowing the industry to even further reduce the use of sulphide.

ERHAVIT LSC – Liming agent for improved hair follicle cleaning-out

ERHAVIT LSC is a reductive unhairing agent based on organic sulphides, and is free of inorganic sulfides and enzymes. It prepares the hair for hair loosening in the Hair-Save unhairing process and improves the cleaning-out of the hair follicle. For optimum removal of hair residues, ERHAVIT LSC is best used together with ERHAVIT LSU. 

ERHAVIT LSR – Highly concentrated reductive unhairing agent replacing sulfide

ERHAVIT LSR is a highly concentrated, low smell reductive unhairing agent based on organic sulphides and free of nitrogen, inorganic sulphides and enzymes. It can partly or completely replace sodium sulphide and sodium hydrosulphide and thus is part of the TFL Low Sulphide System. The unhairing product is a key element in ecological unhairing of hides and skins.

The products present further ecological benefits within the Low Impact Beaming and Tanning strategy of TFL with the target to further increase the use of sustainable, environmentally-friendly chemicals with a good eco tox profile.
