Rockenzyme WS-20 – Enzymatic Soaking Auxiliary for Green and Salted Hides

High-Performance Enzymatic Soaking Agent for Leather Processing

Rockenzyme WS-20 is a specialized enzymatic soaking auxiliary developed for the efficient soaking of green and salted hides and skins. Based on a carefully selected pancreatic enzyme mixture, the product improves the soaking process by promoting the removal of natural impurities, proteins, blood residues, and dirt while helping restore the natural softness and elasticity of raw stock.

Suitable for all types of leather, Rockenzyme WS-20 enhances the penetration of water into the hide structure, ensuring cleaner pelts and better preparation for subsequent beamhouse operations.

Why Choose Rockenzyme WS-20?

The soaking stage is one of the most important steps in leather manufacturing, directly affecting the quality and uniformity of the finished leather. Rockenzyme WS-20 has been designed to optimize this process while preserving the natural fiber structure of hides and skins.

Key Benefits:

• Effective soaking auxiliary for green and salted raw stock.
• Accelerates the removal of proteins, blood, and impurities.
• Improves water penetration into hides and skins.
• Promotes uniform soaking and rehydration.
• Helps restore the natural softness and elasticity of the pelt.
• Supports cleaner and smoother leather surfaces.
• Improves the efficiency of subsequent liming and tanning operations.
• Suitable for different leather types and processing systems.
• Easy to apply directly into the soaking float.

How Rockenzyme WS-20 Works?

Rockenzyme WS-20 contains a pancreatic enzyme complex that acts on non-structural proteins and unwanted organic matter present in raw hides and skins.

During soaking, the enzyme promotes:

• Faster and more uniform rehydration.
• Better opening of the fiber structure.
• Removal of blood, dirt, and soluble proteins.
• Cleaner pelts and grain surfaces.
• Improved penetration of subsequent leather chemicals.

The result is a well-prepared pelt with enhanced softness and consistent quality for the following processing stages.

Applications:

Rockenzyme WS-20 is recommended for:

• Soaking of green hides.
• Soaking of salted hides and skins.
• Bovine leather processing.
• Sheep and goat leather production.
• Beamhouse operations.
• Wet-blue preparation.
• Conventional soaking systems.

Technical Specifications

Recommended Application:

Rockenzyme WS-20 is added directly to the soaking process without prior dissolution.

To achieve optimum enzyme performance, the soaking liquor pH should be adjusted using caustic soda or soda ash:

• Initial pH: 10.0–10.5
• Final pH: 9.0–9.5

Maintaining the recommended pH range ensures efficient enzymatic activity and consistent soaking results.

The exact dosage depends on the type of raw stock, storage conditions, and tannery process parameters.
