Neutral protease

The preparation is widely used in the tanning industry for skins dehairing and bating of hide. The full weakening of the hair connection with the dermis occurs when using enzymes in the process of dehairing.

Wool is separated on the entire length and becomes clean and soft, it can be used as secondary raw materials. The front part of the skins remains compact, shiny, as a result the finished leather has high quality, and their quantity is increased up to 5%.

The consumption norm of neutral protease is 0.02-0.03% of the hide mass. The optimum bating mode is achieved at temperature 39°C and pH of 7.8. The duration of the processing is from 20 to 90 minutes depending on the weighing out of raw materials.
