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) 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). The analysis package covers the following substances Substance CAS N:o Abbreviation Hexamethylcyclotrisiloxane 541-05-9 D3 Octamethylcyclotetrasiloxane 556-67-2 D4 Decamethylcyclopentasiloxane 541-02-6 D5 Dodecamethylcyclohexasiloxane 540-97-6 D6 Tetradecamethylcycloheptasiloxane 107-50-6 D7 Hexadecamethylcyclooctasiloxane 556-68-3 D8 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.

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 using combustion ion chromatography (CIC). By default, TOF is analyzed as total fluorine (TF). If required, total inorganic fluorine (TIF) can be measured as well, and TOF calculated as the difference between TF and TIF. 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.

Direct and oxidative TOP assay for quantification of target PFAS and precursor compounds in packaging materials, designed to verify compliance with the EU Packaging and Packaging Waste Regulation (PPWR).
