Leather Industry
Formic Acid plays a critical role in the leather industry, serving as a depilatory and deashing agent for hides. For example, in the production of high-quality cow leather, formic acid solutions are used to remove hair from cattle hides. By precisely controlling the concentration and treatment time of formic acid, it effectively dissolves the tissue connecting hair to the skin, achieving thorough depilation without compromising the quality of the leather. In the subsequent deashing process, formic acid neutralizes alkaline substances such as lime in the leather, adjusts its pH level, and leaves the leather softer with an enhanced texture.
