How Vanguard tests Aluminum chlorohydrex

Method for the $250 identity, purity and quantity test: ICP-MS metal content, against a reference standard, with results in 3 to 5 business days.

The USP monographs cover identity by chemical tests for aluminum and chloride and infrared spectroscopy, content calculated from aluminum and chloride results, and arsenic and iron limits and pH. Full testing to the USP Aluminum Chlorohydrex Polyethylene Glycol or Propylene Glycol monograph is available and quoted.

What's reported

  • Metal content by ICP-MS, against the label or specification
  • Purity, as percent of total peak area
  • Quantity, against the label claim
  • Identity, reported as match or no match against the reference standard
  • With monograph testing (quoted): the monograph’s tests against its limits

Tests and prices

$250

Questions about Aluminum chlorohydrex testing

Is the $250 test the same as USP monograph testing?

No. The $250 test covers identity, purity and quantity by ICP-MS for metal content. Full testing to the USP Aluminum Chlorohydrex Polyethylene Glycol or Propylene Glycol monograph is available and quoted.

What is the difference between chlorohydrex, dichlorohydrex and sesquichlorohydrex?

They are aluminum chloride hydroxide complexes with different aluminum to chloride ratios, each bound to propylene glycol or polyethylene glycol. The ratio is worked out from the measured aluminum and chloride content.

Why is there no single formula or CAS number?

These materials are polymeric complexes with variable water and glycol content, so the monograph gives a general formula. The test reports aluminum content and, where quoted, chloride and the aluminum to chloride ratio.

Can the salt be tested in a finished antiperspirant?

Yes, aluminum can be measured in a stick, gel or roll-on, but the result is total aluminum for the product. Telling which aluminum salt was used needs the raw material.
