Lipases offer the tanner two advantages over solvents or surfactants: improved fat dispersion and production of waterproof and low-fogging leathers. Alkaline lipases are applied during soaking and/or liming, preferably in combination with the relevant protease. Among other things, the protease opens up the membranes surrounding the fat cell, making the fat accessible to the lipase. The fat becomes more mobile and the breakdown products emulsify the intact fat, which will then distribute itself throughout the pelt so that in many cases a proper degreasing with surfactants will not be necessary. This facilitates the production of waterproof and low-fogging stock. Lipases can also be applied in an acid process, e.g. for pickled skin or wool-on and fur, or a semi-acid process for wet blue.
Not many companies offer this solution by enzymatic way. AESL is one of the few companies offering degreasing enzyme.

SEBDEFAT: is unique degreasing agent for wet blue used for retaining and fat liquoring operation
SEBDEGREASE: is new generation enzyme based ecofriendly biodegradable, degreasing agent. It has optimum swell regulating properties which result in excellent grain smoothness
Given the amount of legislation on the environment tanners are required to reduce all kinds of pollution (solid waste, dissolved or suspended substances in effluents). It is well known that beam house operation cause the highest pollution during the leather manufacturing process. The replacement of the conventional dehairing process with sodium sulfide and lime by a less polluting procedure is of paramount important to the tanner.
Several alternatives to the conventional process have studied from renowned institutes & tanners all over the world. Yet most processes could reduce use of Sulfide to about 40-50% level. Hence, tanners have had to resort to vigorous measures in Effluent Treatment part.

SEBDEFOLD: It is a free flowing white powder for defolding of Leather.
In this final beam-house process, residues of non-collagen protein and other interfibrillary material are removed. This leaves the pelt clean and relaxed, ready for the tanning operation. Traditionally, pancreatic bates have been used, but bacterial products are gaining more and more acceptance. By combining the two types of protease or using SEBate Acid, the tanner gets an excellent bate with synergistic effects which can be applied to all kinds of skin and hide. The desired result of a clean grain with both softness and tightness is achieved in a short time.
Pickled skins and wet-blue stock have become important commodities. A secondary bating is necessary due to non-homogeneity. For skins as well as double face and fur that have not been limed and bated, a combination of an acid protease and lipase or Acid Bate / SEBate Series from AESL ensures increased evenness, softness and uniformity in the dyeing process. Wetblue intended for shoe uppers is treated with a semi-acid protease combined with a lipase, resulting in improved consistency of the stock.

SEBBATE ACID: A versatile acidic bate with combination of different enzymes
SEBBATE ALKALI: It is highly concentrated powder providing better economy of use in bulk leather tanning.
Restoration of the water of salted stock is a process that traditionally applied surfactants of more or less biodegradability. Alkaline Proteases, with a pH optimum around 9-10, are now widely used to clean the stock and facilitate the water uptake of the hide or skin. The enzyme breaks down soluble proteins inside the matrix, thus facilitating the removal of salt and hyaluronic acid. This makes room for the water. Lipases provide synergy.
