Standard Guide for Analyzing Complex Phthalates

Importancia y uso:

5.1 The regulatory candidate list classifies substances by CAS number. Complex branched phthalates, such as DINP or DIDP, manufactured with a defined alcohol distribution and registered by CAS number with a chemical description of the composition, shall be considered a single substance with that composition as described.

5.2 It is possible for the alcohols used in the manufacture of complex branched phthalates to vary in isomer composition. Care must be used to ensure a representative standard is used to the quantitation of the level of a complex branched phthalate.

5.3 This guide is intended to provide a method on how to interpret and determine data from an analysis involving complex branched phthalates with defined CAS numbers. The test procedure employed shall be used to provide speciation information to assist use of the schematic flow diagram.

Note 3: A discussion on analytical challenges in complex branched phthalate analysis is found in: “Analytical Challenges in Detecting Regulated Phthalates in Flexible PVC Products,” SPI Flexible Vinyl Products Division, 23rd Annual Compounding Conference, July 17, 2012.
