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.

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. Sample preparation (air drying and milling of the sample to particles <1 mm) is included in the displayed price.

Content of 15 polycyclic aromatic hydrocarbons (PAHs) in plastic and rubber and products made from them (e.g., toys, kitchenware) according to AfPS GS 2019:01 PAK. If PAH levels are sufficiently low, the product may be granted a GS mark (a voluntary German product safety label). The test package includes the following substances: Naphthalene [CAS: 91-20-3], Acenaphthylene [CAS: 208-96-8] , Acenaphthene [CAS: 83-32-9] , Fluorene [CAS: 86-73-7] , Phenanthrene [CAS: 85-01-8] , Anthracene [CAS: 120-12-7] , Fluoranthene [CAS: 206-44-0] , Pyrene [CAS: 129-00-0] , Benzo(a)anthracene [CAS: 56-55-3] , Chrysene [CAS: 218-01-9] , Benzo(b)fluoranthene [CAS: 205-99-2] , Benzo(k)fluoranthene [CAS: 207-08-9] , Benzo(j)fluoranthene [CAS: 205-82-3] , Benzo(e)pyrene [CAS: 192-97-2] , Benzo(a)pyrene [benzo(def)chrysene] [CAS: 50-32- 8] , Indeno(1,2,3-cd)pyrene [CAS: 193-39-5] , Dibenzo(a,h)anthracene [CAS: 53-70-3] , Benzo(g,h,i)perylene [CAS: 191-24-2].

Targeted screening and quantification of 165 PFAS compounds in various materials with accredited in-house methods based on ISO 23702-1, CNS 15808, and CEN/TS 15968. The service includes both LC-MS/MS analysis of low-volatility PFAS and GC-MS analysis of volatile PFAS substances. Examples of target analytes include PFOS, PFOA, PFHxS, and PFNA. The full list of compounds is available upon request. In addition to plastic and paper, the measurement is suitable for textiles, leather, wood, metals, paints, and coatings.  One common application of this analysis is evaluating compliance with EU and US regulations on PFAS in food packaging. If this is the goal, a total organic fluorine (TOF) analysis should be conducted in addition to the targeted screening. We are happy to provide a single offer that includes both analyses.

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 the oxygen transmission rate of plastic films and sheet-like materials. The test is performed on two parallel samples simultaneously. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Oxygen permeability is typically measured at 23 °C and 0% relative humidity as per standard ASTM D3985. In moist conditions, for example at 38 °C and 90% relative humidity, standard ASTM F1927 is used. Please disclose the desired temperature (from 10 °C to 38 °C) and relative humidity (either 0% or from 20% to 90%) upon ordering. This measurement is suitable for plastic films with OTR values between 0.05 to 20 000 cm³/(m² * day).
