Vartest Accredited to Test For Phthalates Under CPSIA:

Vartest has obtained A2LA accreditation to test for phthalates under the Consumer Product and Safety Improvement Act (CPSIA). This test (designation CPSC-CH-C1001-09.3) provides an excellent complement to Vartest’s lead and heavy metal detection testing services, allowing our laboratory to ensure full safety compliance for a range of materials and products.

Phthalates are compounds of phthalic acid widely used as plasticizers, chemical compounds which increase the strength and malleability of plastics. Found in or on the majority of plastic or polymeric products worldwide, including toys, textiles, garments, and upholstery, phthalates and plasticizers in general are produced and used by the millions of tons per annum. However, phthalates’ weak chemical bond to the plastics in which they are used (specifically, the lack of a covalent bond) allows them to be relatively easily released into the environment when the plastics age. This process has been associated with certain detrimental effects to the environment, resulting in phthalates’ regulation under CPSIA as of February 10, 2009.

Vartest tests for phthalates using the Standard Operating Procedure supplementary to CPSC-CH-1001-09.3, dissolving the sample in a solution of HPLC-grade tetrahydrofuran (THF), precipitating sample polymers with HPLC-grade hexanes, and filtering the solution through a .45μm polytetrafluoroethylene (PTFE) filter. The filtered solution is then subjected to gas chromatography and mass spectrometry (GCMS) to isolate and identify the resultant phthalates. Samples are monitored using both full scan mode and selected ion monitoring (SIM), and our machinery runs a quality control sample each day. Products tested include fabric adhesives, coatings, print applications, children’s products, plastic components of various garments, and other end use items.
