Cosmetic Testing Services
Active Ingredient Purity
HPLC purity quantification for cosmetic actives — retinoids, peptide actives (Argireline, Leuphasyl), vitamin C derivatives, niacinamide, hyaluronic acid.
Identity Confirmation
Mass spectrometry to confirm the identity of active ingredients and raw materials. Detects substitutions, adulterants, and off-spec material.
Preservative Efficacy Testing
Challenge testing to verify that your preservative system effectively inhibits microbial growth under use conditions (ISO 11930 / USP <51>).
Stability Testing
Accelerated and real-time stability to assess physical, chemical, and microbiological stability. Identifies degradation products via HPLC impurity profiling.
pH and Solubility Assay
Confirm pH of finished formulations and solubility profile of active ingredients across relevant pH ranges and solvents.
Toxin & Contaminant Screen
Screening for heavy metals (lead, mercury, arsenic, cadmium), PAHs, nitrosamines, and restricted substances per EU Cosmetics Regulation and FDA requirements.
