Alkaline lipase Greasex 50L is one of the leather enzyme products of Novo Nordisk AS. After extensive control trials on pigskins, evaluating effects by degree of fat removal and qualities of result leather, we got1 Fat removal rate can be increased by 10%and leather qualities such as napping and softness can be improved by using Greasex 50L together with liming enzyme NUE 0.6 MPX2 Some surfactant together with Greasex 50L is good to fat removal, and the recommended ratio is 0.05%～0.1%∶13 The fat content in the skins is lower after treated with Greasex 50L,which also benefits the successive processes, such as bating, pickling and tanning. As a result, the leather qualities, such as fineness of grain, softness, napping and evenness of dyeing can be improved.
