Fatliquoring agent for upholstery and soft leathers
GREIBOSOL G94A
GREIBOSOL G94A is a high-performance fatliquoring agent specifically developed for upholstery and soft leathers, combining outstanding softness properties with a valuable emulsifying function that makes it a versatile component in both single-product and multi-component fatliquoring systems.
Leathers treated with GREIBOSOL G94A are very light and soft with a pleasant waxy touch, supported by good light fastness and heat resistance that make it particularly suitable for upholstery and automotive leather applications where long-term colour and handle stability under light and heat exposure are critical requirements.
A distinguishing feature of GREIBOSOL G94A is its excellent emulsifying capacity: it is readily soluble in water and can be added directly to the float without prior dilution, while simultaneously being capable of emulsifying up to 20% of its own weight of water-insoluble oils. This makes GREIBOSOL G94A an ideal carrier and emulsifier for other fatliquor components within a multi-component fatliquoring recipe, improving the stability and distribution of the overall fatliquor system throughout the leather cross-section.
GREIBOSOL G94A ensures even dyeing and is compatible with other fatliquoring agents, offering maximum flexibility in fatliquor recipe design. Its neutral odour makes it particularly well suited for applications where residual odour in the finished leather is a quality or regulatory requirement, such as automotive upholstery.

Application Examples
GREIBOSOL G94A is the preferred fatliquor wherever a light, soft leather with a pleasant waxy character, reliable light and heat fastness, and the ability to integrate and stabilise other fatliquor components within the recipe are required.
In upholstery leather production for furniture and automotive applications, GREIBOSOL G94A delivers the consistent lightness, softness, and waxy handle expected of premium quality upholstery articles, while its good light fastness and heat resistance ensure that the leather retains its handle and colour stability over the service life of the finished product.
In multi-component fatliquoring systems, GREIBOSOL G94A’s ability to emulsify up to 20% of its own weight of water-insoluble oils makes it a valuable stabilising and distributing component, enabling the incorporation of raw oils and other water-insoluble fatliquor components into a stable, finely dispersed emulsion that ensures uniform distribution throughout the leather fibre structure.
For soft leather articles where even dyeing is a priority, GREIBOSOL G94A supports a uniform and consistent colour distribution across the full hide, making it a reliable choice for light shades, natural colours, and pastel leather articles where colour uniformity is critical.
