Polycyclic aromatic hydrocarbons (PAH) in plastic and rubber (AfPS GS 2019:01 PAK)

Cyclosiloxanes are the primary building blocks of siloxane polymers and, ultimately, silicone rubber. Hence, cyclosiloxanes can remain in the final silicone article as residual impurities. Several cyclosiloxanes (D4, D5, D6; see table below) are considered harmful to the environment and human health. These three substances are listed in the REACH Candidate List of substances of very high concern (SVHC). Substance Abbreviation CAS N:o Octamethylcyclotetrasiloxane D4 556-67-2 Decamethylcyclopentasiloxane D5 541-02-6 Dodecamethylcyclohexasiloxane D6 540-97-6 The Nordic Swan Ecolabel criteria for greaseproof paper sets the limit values for D4, D5, and D6 impurities in silicone coating as 400 ppm per substance and 1000 ppm for the sum of D4, D5, and D6. In addition to the restricted substances listed above, this analysis package includes the quantification of cyclosiloxanes D3, D7, and D8.

Test package includes the following substances: Benzo(a)pyrene [benzo(def)chrysene] [CAS: 50-32-8] , Benzo(e)pyrene [CAS: 192-97-2] , Benzo(a)anthracene [CAS: 56-55-3] , Chrysene [CAS: 218-01-9] , Benzo(b)fluoranthene [CAS: 205-99-2] , Benzo(j)fluoranthene [CAS: 205-82-3] , Benzo(k)fluoranthene [CAS: 207-08-9], Dibenzo(a,h)anthracene [CAS: 53-70-3].

Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. They have also been used as additives in products such as cosmetics and personal care items. Several phthalates have been identified as endocrine-disrupting agents or as chemicals toxic to reproduction. Exposure to phthalates can occur through: Oral exposure Food: Exposure occurs via migration from food packaging., Children's toys: Children often put toys in their mouths.., Inhalation: Breathing in dust from vinyl flooring or fragrances (like perfumes) can cause exposure to phthalates via inhalation., Skin contact: Phthalates present in cosmetics, lotions, and soaps can be absorbed through the skin.. For other listed matrices apart from cosmetics, the analysis package covers the following substances included in the REACH Authorization List: Substance Abbreviation CAS number Diisobutyl phthalate DIBP 84-69-5 Dibutyl phthalate DBP 84-74-2 Benzyl butyl phthalate BBP 85-68-7 Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Di(n-octyl) phthalate DNOP 117-84-0 Diisononyl phthalate DINP 68515-48-0 Diisodecyl phthalate DIDP 26761-40-0 Products that contain restricted phthalates in concentrations higher than 0.1% may be removed from the market. The analysis package for cosmetic products contains the following phthalates: Substance Abbreviation CAS number Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Benzyl butyl phthalate BBP 85-68-7 Dibutyl phthalate DBP 84-74-2 Diisononyl phthalate DINP 68515-48-0 Di(n-octyl) phthalate DNOP 117-84-0 Diisodecyl phthalate DIDP 26761-40-0 All the above-mentioned substances are prohibited in cosmetic products (Annex II of Regulation (EC) No 1223/2009).

Analysis for quantifying dioxins and furans (PCDD/F) in various packaging materials (e.g. food and cosmetics packaging) and their raw materials, including plastics, paper, and rubber. Dioxins and furans are a family of chlorine-containing chemicals considered bioaccumulating, persistent organic pollutants (POPs) that can be toxic even at low doses. While regulatory limits apply mainly to food and feed, packaging materials can be a source of indirect exposure to dioxins and furans. Recycled materials tend to pose relatively high risks, depending on the quality of the raw material and the effectiveness of the decontamination process. The following substances are included in the analysis: Dibenzo-p-dioxins (PCDDs) Polychlorinated dibenzofurans (PCDFs) 2,3,7,8-TCDD. 2,3,7,8-TCDF. 1,2,3,7,8-PeCDD. 1,2,3,7,8-PeCDF. 1,2,3,4,7,8-HxCDD. 2,3,4,7,8-PeCDF. 1,2,3,6,7,8-HxCDD. 1,2,3,4,7,8-HxCDF. 1,2,3,7,8,9-HxCDD. 1,2,3,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDD. 1,2,3,7,8,9-HxCDF. OCDD. 2,3,4,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDF. 1,2,3,4,7,8,9-HpCDF. OCDF. Testing is often performed for the following reasons: Analyzing recycled PE, PP, and LDPE intended for cosmetics packaging according to CosPaTox guidelines., Analyzing paper and board bleached with elementary chlorine according to the requirements of TemaNord 2008:515 guidelines..

Determination of the total organic fluorine (TOF) content in combustible materials by combustion ion chromatography (CIC). TOF analysis gives information about the total amount of organic fluorinated compounds. It can also be used to evaluate the presence of per- and polyfluoroalkyl substances (PFAS) in the material, even though individual PFAS compounds can't be analyzed with this method. The analysis is suitable for many different materials. Please describe the sample in detail when requesting an offer to help us prepare a quote quickly.

Extended analysis package for phthalates in various matrices using the GC-MS technique. Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. Phthalates are also found as additives in products, including cosmetics and personal care items. Several phthalates have been identified as being endocrine-disrupting or toxic to reproduction. Exposure to phthalates can occur, e.g., through food (chemicals can transfer from packaging), children's toys (when put in their mouths), and dust from vinyl flooring.

Targeted screening and quantification of 164 PFAS compounds in various types of food contact materials with GC-MS/MS and LC-MS/MS methods. The analysis is also suitable for materials intended for other applications. Examples of target analytes include PFOS, PFOA, PFHxS, and PFNA. The full list of compounds is available upon request. Note that when evaluating compliance with EU or US regulations on PFAS in food packaging, a total organic fluorine (TOF) analysis should be conducted in addition to the targeted screening. We are happy to provide a formal offer for both analyses.
