We deliver reliable, defensible data that supports product safety dossiers, regulatory notifications, and consumer confidence in an increasingly scrutinized market.
Our security and compliance testing services address a wide range of regulatory and safety concerns, including but not limited to:
The European Union has significantly expanded the list of fragrance allergens requiring mandatory labeling under Regulation (EU) 2023/1545, with enforcement beginning July 2026. The updated regulation mandates the identification and quantification of 81 additional fragrance allergens beyond the original 26 substances. Our expanded allergen screening service employs targeted GC-MS and LC-MS/MS methodologies to deliver comprehensive, quantitative data that ensures your products remain compliant with the most current EU requirements.
| Analytical Method | Description and Regulatory Context |
|---|---|
| GC-MS Targeted Allergen Quantification | Gas chromatography-mass spectrometry method optimized for volatile and semi-volatile fragrance allergens. Covers the full expanded EU allergen list with detection limits below the 0.001% (leave-on) and 0.01% (rinse-off) labeling thresholds set by Regulation (EU) 2023/1545. |
| LC-MS/MS for Non-Volatile Allergens | Liquid chromatography-tandem mass spectrometry for fragrance allergens with low volatility or thermal sensitivity that are not amenable to GC analysis. Ensures complete coverage of the expanded allergen panel. |
| Allergen Content Compliance Report | Comprehensive reporting with quantitative results for each detected allergen, comparison against regulatory thresholds, and clear pass/fail assessment for EU labeling compliance. |
Per- and polyfluoroalkyl substances (PFAS) have emerged as a significant regulatory concern in cosmetics, driven by proposed restrictions in France, several U.S. states, and the European Union. PFAS compounds may be present as intentionally added ingredients (e.g., film formers, emulsifiers) or as unintended contaminants from raw materials and processing aids. Our PFAS screening services combine targeted quantitation with non-targeted discovery workflows to provide a complete picture of fluorinated compound presence in your products.
| Analytical Method | Description and Regulatory Context |
|---|---|
| LC-QTOF High-Resolution Mass Spectrometry | High-resolution accurate mass analysis enabling both targeted quantification of known PFAS compounds and non-targeted screening for unknown or emerging fluorinated substances. The QTOF platform provides the mass accuracy and sensitivity required to detect PFAS at trace levels in complex cosmetic matrices. |
| Targeted PFAS Panel Quantification | Quantitative determination of a defined panel of priority PFAS analytes using isotope dilution and reference standards. Covers compounds of regulatory interest under current and proposed restrictions. |
| Total Organic Fluorine Screening | Combustion ion chromatography (CIC) for total organic fluorine as a screening tool to assess the overall PFAS burden in raw materials and finished products, complementing compound-specific analyses. |
Mineral oil hydrocarbons can migrate from packaging materials into cosmetic products, raising concerns about the accumulation of mineral oil aromatic hydrocarbons (MOAH), which may contain potentially genotoxic and carcinogenic constituents, and mineral oil saturated hydrocarbons (MOSH), which can accumulate in human tissues. Our LC-GC coupled analysis provides the most reliable methodology for MOAH/MOSH determination in compliance with European regulatory guidance.
| Analytical Method | Description and Regulatory Context |
|---|---|
| LC-GC Online Coupled Analysis | Online coupled liquid chromatography-gas chromatography with flame ionization detection (LC-GC-FID), the reference method for MOAH and MOSH determination. The LC step separates MOSH and MOAH fractions, which are then individually analyzed by GC to produce quantitative hydrocarbon profiles. |
| MOSH Quantification by Carbon Number Range | Quantitative determination of MOSH fractions (C10–C50) in cosmetic products and raw materials, with reporting by carbon number range to support risk assessment according to German BfR and EU recommendations. |
| MOAH Detection and Quantification | Sensitive detection and quantification of MOAH at sub-ppm levels, with characterization of the aromatic hydrocarbon profile to distinguish between alkylated and non-alkylated MOAH species. |
The global shift away from animal testing has created a pressing need for integrated, non-animal approaches to cosmetic safety assessment. Our NGRA services combine computational predictive tools, in vitro toxicity testing, and exposure modeling in a structured framework aligned with the International Cooperation on Cosmetics Regulation (ICCR) principles. This integrated approach delivers a scientifically defensible safety assessment that meets regulatory expectations in the United States, the EU, and China.
| NGRA Component | Description and Application |
|---|---|
| In Silico Predictive Modeling (QSAR) | Quantitative structure-activity relationship modeling using established computational platforms to predict toxicological endpoints including genotoxicity, skin sensitization, and repeated-dose toxicity based on chemical structure. |
| In Vitro Cytotoxicity Profiling | Cell viability assessment in human dermal fibroblasts and keratinocytes to establish concentration-response relationships and determine points of departure for risk assessment. |
| Exposure Assessment (PBPK Modeling) | Physiologically based pharmacokinetic modeling to estimate systemic exposure following dermal application, accounting for product type, application frequency, and body surface area. Provides the exposure component of the margin of safety calculation. |
| Integrated Safety Dossier | Compilation of all NGRA data into a structured safety assessment report following the ICCR framework, suitable for inclusion in Product Information Files (PIF) and regulatory notifications. |
Phototoxicity occurs when a chemical substance absorbs UV or visible light and transfers the absorbed energy to biological targets, causing tissue damage. Certain cosmetic ingredients, particularly those in leave-on products and sunscreens, have the potential to induce phototoxic reactions. Our in vitro phototoxicity testing follows the OECD Test Guideline 432, providing a validated, animal-free method for assessing phototoxic potential.
| Test Method | Description and Regulatory Context |
|---|---|
| 3T3 Neutral Red Uptake Phototoxicity Test (OECD TG 432) | Assessment of the relative reduction in viability of Balb/c 3T3 fibroblasts exposed to the test article in the presence versus absence of a non-cytotoxic dose of simulated solar irradiation. The photoirritation factor (PIF) and mean photo effect (MPE) are calculated to classify phototoxic potential. This OECD-validated method is accepted by regulatory authorities worldwide as a stand-alone test for phototoxicity. |
| UV-Vis Spectral Analysis | Pre-screening of test articles by UV-visible spectrophotometry to determine light absorption in the 290–700 nm range. Substances without significant absorption in this range may be exempted from further phototoxicity testing. |
Eye irritation potential is a critical safety endpoint for all cosmetic products, particularly those intended for use near the eye area. Our in vitro eye irritation testing utilizes reconstructed human corneal epithelium models that closely mimic the morphological and biochemical properties of the human cornea. This approach provides reliable discrimination between non-irritant, mild irritant, and irritant substances without the use of live animals or human volunteers.
| Test Method | Description and Regulatory Context |
|---|---|
| Reconstructed Human Corneal Epithelium (RhCE) Assay | Topical application of the test article to a three-dimensional reconstructed human corneal epithelium model followed by measurement of tissue viability via MTT reduction. The assay reliably distinguishes non-irritant (UN GHS No Category), mild irritant (Category 2), and irritant (Category 1) substances. This method is accepted under OECD Test Guideline 492 and is suitable for a wide range of cosmetic product types. |
| Hemolysis Test for Ocular Irritancy Screening | Complementary screening assay evaluating the hemolytic potential of test articles on red blood cells as an indicator of ocular membrane damage. Provides rapid, cost-effective preliminary screening prior to more detailed RhCE testing. |
A: Regulation (EU) 2023/1545 becomes enforceable in July 2026 for new products placed on the market. Given the significant expansion from 26 to over 80 fragrance allergens, we recommend initiating screening of your current product portfolio as early as possible to identify reformulation needs and avoid supply chain disruptions.
A: Targeted analysis quantifies specific, known PFAS compounds against certified reference standards. Non-targeted analysis uses high-resolution mass spectrometry to detect any fluorinated compounds present, including novel or unexpected PFAS species that may not be on standard target lists. A comprehensive PFAS strategy typically employs both approaches.
A: NGRA frameworks are increasingly recognized by regulatory bodies worldwide, including the EU Scientific Committee on Consumer Safety (SCCS), as the appropriate path forward for cosmetic safety assessment in the absence of animal data. Our NGRA dossiers are structured to meet the expectations outlined in ICCR guidance and relevant SCCS notes of guidance.
A: Phototoxicity testing is particularly relevant for leave-on products applied to sun-exposed skin, including facial creams, serums, hand creams, lip products, and any formulation containing UV-absorbing ingredients. Products that are rinsed off immediately or are not applied to light-exposed skin may be of lower priority. A UV-Vis absorption pre-screen can help determine whether phototoxicity testing is warranted for your specific product.
A: We test both finished cosmetic formulations and individual raw materials or ingredients. Testing finished products provides the most direct assessment of consumer safety, while raw material testing is essential for supplier qualification and proactive risk management in the formulation development stage.
