Electrolyte stable AOX free fatliquor

GREIBOSOL G64

GREIBOSOL G64 is a high-performance fatliquor based on a special mixture of anionic and non-ionic fatty substances, developed to deliver outstanding softness and excellent fibre binding in the production of high-quality leather. The product is free from AOX compounds and readily biodegradable, reflecting a commitment to both product performance and environmental responsibility.

The formulation of GREIBOSOL G64 ensures a very uniform distribution of natural fat substances throughout the leather cross-section, resulting in consistently soft, fluffy leather with a well-defined handle. Its high electrolyte stability makes it a reliable choice across a broad range of wet-end conditions, maintaining consistent performance even in liquors with elevated salt concentrations.

GREIBOSOL G64 offers excellent lightfastness and outstanding stability to heat ageing, properties that are particularly valued in leathers intended for demanding end uses such as automotive upholstery, furniture, and high-grade fashion articles. These characteristics ensure that the leather retains its appearance and mechanical properties throughout its service life.

A further notable property of GREIBOSOL G64 is its contribution to very uniform dyeing results. By promoting even distribution of fat substances within the fibre structure, the product supports level dye penetration and consistent colour development across the full surface of the leather.

Application Examples

GREIBOSOL G64 is well suited to the production of soft, high-quality leathers across a variety of end uses, including upholstery leather, garment leather, and fashion accessories. Its ability to deliver a fluffy, uniform handle whilst maintaining excellent fibre binding makes it a versatile fatliquor for both light and medium-weight articles.

Due to its high electrolyte stability, GREIBOSOL G64 performs reliably in liquors containing elevated concentrations of neutral salts, as commonly encountered in post-chrome and retanning stages. This stability ensures that the fatliquoring effect is not compromised by the presence of electrolytes in the process bath.

The uniform distribution of fat substances achieved with GREIBOSOL G64 also has a direct positive effect on subsequent dyeing operations. Leathers fatliquored with GREIBOSOL G64 typically exhibit very level dye uptake and consistent shade development, reducing the risk of unlevel dyeing in production.

For leathers intended for dry-cleaning applications, GREIBOSOL G64 provides the necessary resistance to solvent exposure whilst retaining the desired softness and handle characteristics throughout the cleaning process.

In main fatliquoring for stabilization about 10% of the total amount of fatliquor used.
