Metal analysis


Chemical Composition and Formula Compliance Analysis

Evaluation of product formulation compliance and control of substances regulated under cosmetic safety requirements.

  • Active Ingredient Analysis
  • Screening of Prohibited and Restricted Substances according to regulatory requirements
  • Heavy Metals and Contaminant Analysis
  • PFAS and Total Fluorine Analysis
  • Stability Testing
  • Product–Packaging Compatibility Testing
  • Toxicological Assessment and selected In vitro testing

Metal analysis is performed for a broad range of elements, including:

  • Aluminium
  • Arsenic
  • Herbs, Spice and condiments
  • Arsenic trioxide (As₂O₃)
  • Barium
  • Beryllium
  • Cadmium
  • Cobalt
  • Chromium

  • Lead
  • Antimony
  • Selenium
  • Tin
  • Zinc
  • Mercury

Testing is conducted using validated in-house methods, referencing ISO 21392:2021 and EPA Method 7473 for mercury analysis, ensuring analytical accuracy suitable for cosmetic safety assessment.


Microbiological Testing

Assessment of product microbiological safety and control of biological contamination risks.

  • Specific Microorganism Testing for pathogens or objectionable organisms relevant to consumer safety
  • Non-Specific Microorganism Testing (Total Microbial Count) to monitor overall contamination levels
  • Preservative Efficacy Testing (Challenge Test) to evaluate the effectiveness of the preservative system throughout the product’s shelf life

Safety and Performance Evaluation

Support for clinical-level safety and efficacy assessments to substantiate product claims.

  • Skin Irritation and Safety Testing (e.g., HRIPT – Human Repeat Insult Patch Test)
  • Dermatological and Ophthalmological Testing
  • Testing for Sensitive Skin and Specific Target Groups
  • Anti-aging Efficacy Testing
  • Instrumental Measurement of Hydration, Skin Elasticity, and TEWL (Transepidermal Water Loss)
  • SPF Testing
  • Deodorant Efficacy Testing
  • Image-based Evaluation and Digital Image Analysis

These services support substantiation of claims such as:

  • Dermatologically Tested
  • Non-Irritating
  • Suitable for Sensitive Skin
  • And other regulatory-compliant product claims

All testing is performed using appropriate scientific methodologies to generate reliable, defensible data suitable for regulatory submission and market compliance.
