Basic Chromium Sulfate is a trivalent chromium salt supplied as a chemical raw material, also referred to as basic chromium sulfate tanning salt, basic chromic sulfate, or chromium(III) basic sulfate in technical documentation. Identified by CAS 10101-53-8, it consists of chromium(III) coordinated with sulfate and hydroxyl groups, forming a partially neutralized structure that enables controlled interaction with collagen fibers. It is typically applied as a chrome tanning agent in industrial leather processing systems where stable chromium fixation and reproducible tanning behavior are required. From a supply perspective, the material is provided with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

FAQ - Technical & Supply Chain
-
Q:
How is basic chromium sulfate different from chromium sulfate?
A: Basic chromium sulfate contains hydroxylated chromium species, while chromium sulfate is a neutral salt without basicity, leading to different reactivity in tanning systems. -
Q:
Is basic chromium sulfate mainly supplied for industrial tanning processes?
A: Yes. It is typically supplied as an industrial raw material intended for use in chrome tanning formulations rather than as a finished product.
