EPIZOZYME-ANWA is an enzyme-based bating agent with an optimum efficiency at a PH range of 3-5.5. it can be used up to temperatures of 55˚C. Its dosage should be around 0.3-0.5%on hide and skin weight; in any case, it's suggested to EPIZOZYME-ANWA in small scale before going full stream in order to detect its best dosage in the process.

Attention: In order to high activity of this bating agent it should be used carefully in PH range above 6.5 and if in this condition is used in excess amount or time maybe cause damage in the hides or skins.

It is therefore extremely suitable for the application in the pickle process to remove pickle folds and to achieve a clean grain.

Wet blue can be treated with EPIZOZYME-ANWA to level out the differences of the raw material and to improve the evenness and shade intensification of the dyeing. Also when our wet blue needs extra bating by this agent it get-at-able.

An acidic bate with EPIZOZYME-ANWA is Particularly recommended for wet blue showing a very compact and irregular fiber structure such as calf or goat skins.

It improves the evenness of the leather due to a better opening up of the fibers. Application of EPIZOZYME-ANWA often increase cutable area into the normally loose belly area resulting in an even larger improvement in area.


- Anti-wrinkling properties for both pickled hides and skins and wet blues.
- Remove the fold marks in pickled skins and wet blues.
- Noticeably increase the tear strength.
- Improve the smoothness and softness of grain.
- Increase the shade intensification of the dying.
- Increase the area yield (between 3-5%).

Recommendation for dissolving:
EPIZOZYME-ANWA can be dissolved in cold water or added undissolved.

Maximum one Year if stored dry.EPIZOZYME-ANWA should be stored dry and below 30˚C. opened packing should be consumed within 4 weeks.

Although EPIZOZYME-ANWA provided in a low dust formulation slight dust formulation can occur when weighing out the product (wear a protective face mask).
