Chromium chloride

Chromium chloride suppliers and sourcing guide

Chromium chloride for food and supplement use is chromium (III) chloride, usually the hexahydrate, made by dissolving chromium (III) oxide or hydroxide in hydrochloric acid and crystallizing. It forms dark green, hygroscopic crystals that dissolve in water and contain about 20% chromium. Because chromium is dosed in micrograms, brands buy it as a diluted trituration or inside a trace mineral premix.

Forms and grades of chromium chloride

Suppliers sell different products under the same name. Specify the one you need.

Hexahydrate crystals
The USP grade, used by premix and trituration makers.
Triturations
Chromium chloride diluted on a carrier to a stated chromium level.
Mineral premixes
Blends with other trace minerals at fixed ratios.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Assay: Chromium chloride content by titration or chromium by ICP-OES.
Hexavalent chromium: A limit test for chromium(VI), which should not be present.
Water content: Confirms the hexahydrate.
Iron and other metals: Limits on iron, lead and arsenic by ICP-MS.
Content uniformity: For triturations, assay of several samples from the lot.

Storage, lots and expiry

Storage and shelf life

Chromium chloride hexahydrate absorbs moisture readily, so keep it in tightly sealed containers in a dry place. Triturations should also be protected from humidity. Shelf life is set by the supplier's specification, with assay and hexavalent chromium the usual retest checks.

Lots and expiry dates

Record the chromium assay, dilution strength and hexavalent chromium result for each lot, and double-check dosing math between the pure salt and triturations.
