Product Overview
Formic Acid 90% (HCOOH), also known as methanoic acid, is a highly concentrated organic acid widely used in industrial, agricultural, and chemical processing applications. This technical-grade solution provides strong acidity, rapid reactivity, and excellent solubility, making it ideal for descaling, pH control, leather processing, textile dyeing, and chemical manufacturing.

Formic acid is valued as a more biodegradable alternative to mineral acids while still delivering powerful performance in cleaning, antimicrobial control, and industrial processing. Its versatility and consistent concentration make it a reliable choice for demanding applications requiring a strong, fast-acting acid.
