Auxiliaries for leather finishing
Auxiliaries for leather finishing
Auxiliaries in leather finishing encompass a wide range of additives—including softeners, leveling agents, anti-tack components, and film formers—designed to improve the feel, uniformity, and functionality of the final leather product. Historically, many of these auxiliaries contained solvents, heavy metals, or non-biodegradable surfactants that raised environmental and health concerns during application and downstream processing. Sustainable alternatives now emphasize water-based systems, solvent-free carriers, and readily biodegradable components that meet the rigorous environmental criteria set by Leather Working Group (LWG), ZDHC, and regional environmental agencies. These auxiliaries maintain key performance attributes—like gloss, touch, and mechanical durability—while improving air and water emissions profiles. As the leather industry moves toward increased traceability and responsible chemical use, suppliers offering transparent ingredient disclosure, validated environmental impact data, and compatibility with cleaner production technologies are in higher demand. B2B networks support tannery sourcing teams in identifying auxiliaries that are both high-performing and sustainable—helping brands maintain product quality while advancing environmental stewardship.
