REACH ISO Sodium Formate in Leather Industry: Dosage, Methods & Best Practices

Product Description:

Sodium formate, a simple organic salt with the chemical formula HCOONa, has become an indispensable auxiliary agent in modern leather production. Its unique properties—mild reactivity, pH-regulating capabilities, and compatibility with various processing chemicals—make it a valuable asset across multiple stages of leather manufacturing, from raw hide treatment to the final finishing touches.​

Applications:

In the critical tanning phase, sodium formate plays a dual role that directly impacts leather quality. During chrome tanning, the most widely used tanning method today, maintaining a stable pH between 3.8 and 4.2 is essential for ensuring chromium salts bond effectively with collagen fibers. Sodium formate acts as a reliable buffer here, slowly releasing formate ions to prevent abrupt pH fluctuations that could cause chromium precipitation or uneven tanning. This not only improves chromium absorption rates by up to 15% in industrial settings but also enhances the leather’s resistance to heat and moisture, key attributes for durable end products. Additionally, after the acid-intensive pickling process, sodium formate serves as a mild neutralizer, gently raising the hide’s pH to 5.0–5.5, creating optimal conditions for subsequent retanning and dyeing without damaging delicate collagen structures.
