Derminol Liquor

Derminol Liquor is a high-performance fatliquor used in the leather tanning industry, specifically during the retanning and fatliquoring stages of wet-end leather processing. It is an emulsified blend of synthetic, semi-synthetic, or natural-based oils designed to impart softness, flexibility, and lubricity to leathers. Derminol Liquor provides deep penetration, excellent grain lubrication, uniform softness, and high lightfastness. It is compatible with both chrome-tanned and vegetable-tanned leathers. Derminol Liquor enhances leather feel, milling behavior, and aging resistance, and can be used alone or in combination with other fatliquors to achieve specific leather characteristics. It also contributes to environmental compliance by offering low BOD/COD values in effluents.
Description
Derminol Liquor Uses
Primary UsesÂ
- Leather Tanning and Retanning
- Used in the fatliquoring stage to reintroduce essential oils into leather after tanning, restoring softness and flexibility lost during tanning.
- Ensures deep fiber penetration and even distribution of lubricants throughout the hide.
- Suitable for full-grain, corrected grain, split leathers, and nubuck.
- Enhances grain tightness, reduces brittleness, and improves resistance to cracking during flexing.
- Provides softness without tackiness, allowing for easy mechanical handling and further processing.
- Used in the production of garments, footwear uppers, upholstery, belts, and automotive leathers.
- Grain Lubrication and Milling Behavior
- Improves grain break and surface smoothness, ensuring a soft handle and silky touch.
- Promotes uniform milling, allowing for enhanced grain pattern and character in finished leather.
- Helps prevent grain rupture during mechanical operations like staking or toggling.
- Heat and Light Stability
- Provides heat stability to leather, making it suitable for hot plate pressing and drying.
- Offers excellent lightfastness, making it ideal for pale or pastel-colored leathers.
- Dye Affinity Enhancement
- Improves dye penetration and uniformity by opening up the fiber structure.
- Facilitates deeper, richer coloration in dyed leathers.
Secondary UsesÂ
- Water-Repellent Leather Formulations
- Certain Derminol variants provide moderate hydrophobicity, useful in the production of water-resistant or water-repellent leathers.
- Used in combination with hydrophobic agents for waterproof footwear and outdoor leather goods.
- Specialized Leather Effects
- Employed in the creation of suede, nubuck, and brushed leathers to achieve unique surface textures.
- Supports the development of soft, waxy, or oily leathers with deep, luxurious hand-feel.
- Low Environmental Impact Leather Processing
- Formulated to reduce COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) values in wastewater.
- Suitable for use in eco-friendly or ZDHC-compliant leather production systems.
- Leather Restoration and Reconditioning
- Used in post-tanning or restoration processes to soften and rejuvenate dried or aged leather.
- Improves feel and pliability of restored leather without altering original color or finish.
