Purpose and Scope
This test method is an alternate to AATCC Method 149, Chelating
Agents: Chelation Value of Aminopolycarboxylic Acids and Their
Salts; Calcium Oxalate Method.
The active ingredient content of ethylenediaminetetraacetic acid
(EDTA), N-hydroxyethylethylenediaminetriacetic acid (HEDTA) and
diethylenetriaminepentaacetic acid (DTPA) and their salts is
usually expressed by the calcium chelation value (CaCV). Titration
with a calcium salt using either oxalate or a dye indicator, as
done in AATCC Method 149, yields a value which includes partially
substituted EDTA, HEDTA, DTPA, nitrilotriacetic acid (NTA),
iminodiacetic acid (IDA), glycolate and other weak chelating agents
found in some commercial products. This alternative procedure
excludes the effect of the partially substituted products,
providing a more stringent value.
