UNITED STATES CONSUMER PRODUCT SAFETY COMMISSION DIRECTORATE FOR LABORATORY SCIENCES DIVISION OF CHEMISTRY 10901 DARNESTOWN RD GAITHERSBURG, MD 20878 Test Method: CPSC-CH-C1001-09.3 Standard Operating Procedure for Determination of Phthalates April 1st, 2010 This document provides detailed information on test methods that will be used by the U.S. Consumer Product Safety Commission’s (CPSC) testing laboratory (LSC) for the analysis of phthalate content in children’s toys and child care articles covered by the standard set forth in the Consumer Product Safety Improvement Act Section 108. It has been concluded that in order to protect children from the hazard the Act intended to address, that “concentrations of more than 0.1 percent” must apply per plasticized component 1 part of a children’s toy or child care article . CPSC staff has determined that using an appropriate combination of the methods of extraction and analysis presented herein is sufficient to determine the concentration of the six regulated phthalates in most consumer products. Adjustments may be necessary for products made from certain materials, and should be based on sound chemistry and materials science knowledge as well as appropriate solvents for the materials. The general approach is to dissolve the sample completely in tetrahydrofuran, precipitate any PVC polymer with hexane, filter and then dilute the solution with cyclohexane, and analyze by Gas Chromatography-Mass Spectrometry (GC-MS). Definitions 1. Sample – An individual consumer product or a group of identical consumer products from a batch to be tested. 2. Component Part – Individual sub-unit within a product.
