Use of 2-mercapto-pyridine-N-oxide its salts and metal complexes for the preservation of animal skins and leather

摘要

The use of mercapto-pyridine-N-oxide and/or its alkaline earth salts, and its metal complexes for preserving animal skins and leather is described. The mercapto-pyridine-N-oxide in combination with a phenolic active ingredient is suitable for the protection and preservation of animal skins and feathers. Wet chrome leathers treated with the combination incubated for 28 days at 95% relative humidity at 20-30 degrees Celsius exhibited no mould growth after at least 28 days.
