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.

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.

Screening of volatile organic compounds (VOC) from paper, board, and plastics. The method can be used to analyze volatile residues from printed packaging. For evaluation of recycling process efficiency, please see our extended package for VOC screening.

Alkyl ketene dimers (AKD) are used as hydrophobic sizing agents in paper and board to improve water resistance. However, AKDs not bound by the fiber matrix can hydrolyse into dialkyl ketones (DAKs). For paper and board intended for food contact, BfR recommendation XXXVI states that DAK transfer into foodstuff may not exceed 5 mg/kg food. The package includes an analysis of the following substances from a food simulant: Substance Structure CAS No 16-Hentriacontanone (palmitone) C31H62O 502-73-8 16-Tritriacontanone C33H66O 15740-35-9 18-Pentatriacontanone (stearone) C35H70O 504-53-0 The analysis can be performed with the following simulants and approaches: Food simulant Type of testing Applicable standard Iso-octane Conventional migration EN 13130-1 Iso-octane Solvent extraction EN 15519 Tenax Conventional migration EN 14338

Determination of mineral oil saturated hydrocarbons (MOSH) with polyolefin oligomeric saturated hydrocarbons (POSH) and mineral oil aromatic hydrocarbons (MOAH) in various matrices, including: Food contact materials (e.g., paper, board, plastics, rubber), Printing inks (incl. carbon black), Cosmetic products and raw materials, Lubricating oils and greases, white oils. The results are reported as the concentrations of fractions of MOSH/POSH and MOAH, with grouping based on the number of carbon atoms in the substances. The reported fractions are listed in the table below: MOSH/POSH (C10-C50), total MOAH (C10-C50), total MOSH/POSH (≥C10-≤C16) MOAH (≥C10-≤C16) MOSH/POSH (>C16-≤C20) MOAH (>C16-≤C25) MOSH/POSH (>C20-≤C25) MOAH (>C25-≤C35) MOSH/POSH (>C25-≤C35) MOAH (>C35-≤C50) MOSH/POSH (>C35-≤C40) MOSH/POSH (>C40-≤C50) In case the sample contains high amounts of MOSH, POSH, or poly alpha olefins (PAO), the levels should be indicated before shipping samples. Moreover, the LOQ is higher for samples with high MOSH, POSH, or PAO content due to dilution. Additionally, the safety data sheets (SDS) should be supplied with the samples when available.

Determination of bisphenol S content in various matrices, including: Consumer goods made from plastic, elastomers, and rubber, Food packaging (plastic, paper, multi-materials). Testing is recommended especially for paper and board food packaging that contains recycled fibers and comes into contact with moist and fatty foods. To be compliant with German BfR Recommendation XXXVI, such packaging must not release bisphenol S into food in amounts exceeding 0.05 mg/kg. Extraction is possible with various techniques, including: Solvent extraction, Cold water extract (EN 645), Hot water extract (EN 647), Solvent extract (EN 15519).

We offer several accredited methods for determining the total fluorine (TF) content of combustible materials: EN 14582, based on combustion ion chromatography (CIC). The method is recommended by the Nordic Council of Ministers as a quick and powerful total fluorine screening technique., EN 15408 using oxygen bomb combustion treatment followed by ion chromatography (IC). This method can be applied to plastic sheets and granules, and it is also possible to determine the total content of S, Cl, and Br. , ASTM D7359-23, based on oxidative pyrohydrolytic combustion, followed by CIC.. The most suitable method is typically selected based on the sample matrix. However, please let us know if you wish a specific standard to be followed.
