FAQ - Technical & Supply Chain
-
Q:
Are Calcium Stearate and Calcium Distearate the same material?
A: Yes. Calcium Stearate and Calcium Distearate are commonly used for CAS 1592-23-0. A commercial calcium stearate grade may nevertheless reflect its fatty-acid feedstock, manufacturing route and physical form. Confirm the CAS number, calcium or ash basis, free fatty acid and intended-use grade rather than approving the name alone. -
Q:
Which specifications should be agreed for Calcium Stearate?
A: Agree calcium or ash content, free fatty acid, moisture, melting range, bulk density, color and particle-size distribution, with the test methods stated. Polymer, construction, pharmaceutical and other grades may use different feedstock and impurity controls. Compare the batch COA with the application-specific TDS before approving a substitute. -
Q:
How should the physical form of bulk Calcium Stearate be selected?
A: Powder offers high surface area and dispersion but can create more dust; low-dust granules improve flow and dosing. Specify powder, fine powder or granule form, particle limits, bulk density, dusting requirement, bag liner and pallet pattern. Also confirm animal, vegetable or other fatty-acid origin when the destination market requires that declaration.
