Cosmetic & Personal Care Product Testing
Independent Cosmetic Testing, Skincare Analysis & Formulation Characterization
Cosmetic and personal care products are complex formulations that combine oils, polymers, surfactants, pigments, preservatives, active ingredients, fragrances, minerals, botanical materials, and functional additives. Small changes in raw materials, processing, packaging, storage, or ingredient compatibility can affect appearance, stability, quality, and performance.
Materials Metric provides independent cosmetic testing and personal care product analysis for beauty brands, skincare companies, makeup manufacturers, contract manufacturers, formulators, ingredient suppliers, startups, researchers, and individual clients. Our work can support formulation development, quality investigations, contaminant screening, supplier evaluation, competitive product analysis, and customized scientific troubleshooting.
Industry Risks & Technical Challenges
Common technical challenges may include:
- Emulsion separation, sedimentation, precipitation, or viscosity changes
- Unexpected discoloration, odor changes, oxidation, or ingredient degradation
- Trace metals or other contaminants in pigments, minerals, and finished products
- Raw-material variability and supplier-related composition differences
- Particle agglomeration, dispersion problems, or inconsistent pigment distribution
- Packaging interactions, extractables, residues, or product-container incompatibility
- Batch-to-batch differences in composition or physical behavior
- Unknown ingredients, foreign particles, residues, or manufacturing contaminants
Our Analytical Approach to Cosmetic Product Testing
Cosmetic testing is most useful when the analytical plan is matched to the formulation and the specific question. Depending on the product, Materials Metric may combine chemical, elemental, thermal, microscopic, physical, and microbiological methods to build a more complete understanding of formulation behavior.
- ICP-MS or ICP-OES for trace metals and elemental composition
- GC-MS and LC-MS/HPLC for volatile, semi-volatile, preservative, active, and formulation components
- FTIR and Raman spectroscopy for ingredient, polymer, residue, and material identification
- SEM/EDS and microscopy for particles, pigments, morphology, residues, and foreign material
- DSC and TGA for thermal behavior, volatile content, transitions, and compositional comparisons
- Particle-size, rheology, pH, viscosity, and other physical characterization where appropriate
- Stability, microbiology, or preservative-efficacy studies through the appropriate specialized workflow when included in scope
- Comparative analysis of reference, competitor, control, and problem formulations
Standards & Technical Frameworks
Cosmetic test plans depend on product type, intended market, formulation, claim, and project objective. Where relevant, studies may be designed with reference to recognized cosmetic, microbiological, analytical, or client-specific methods. Regulatory responsibility and market-specific requirements should be confirmed for the intended product and jurisdiction.

Common Cosmetic Investigations We Support
- Why is a cream, lotion, or serum separating?
- Why did a cosmetic product change color, odor, viscosity, or texture?
- Does a makeup product or pigment contain trace metals?
- Why are two production batches analytically different?
- What is an unknown particle, residue, or contaminant in a finished product?
- How does a prototype compare with a reference or competitor formulation?
- Did a raw-material or supplier change alter the product?
- What analytical methods can help characterize a proprietary cosmetic formulation?

Frequently Asked Questions
What testing can be performed on cosmetic products?
Cosmetic products can be evaluated using chemical, elemental, physical, thermal, microscopic, microbiological, and stability-related methods. The most appropriate test plan depends on the formulation, intended use, suspected problem, target market, and the decision the data must support.
Can makeup be tested for heavy metals?
Yes. Techniques such as ICP-MS or ICP-OES can quantify selected metals in makeup, pigments, mineral ingredients, and other cosmetic materials after appropriate sample preparation. The element list and reporting limits should be defined based on the product and project objective.
Can you compare our cosmetic formula with a competitor?
Yes. Comparative analytical testing can identify measurable similarities and differences in chemical fingerprints, elemental composition, pigments, particles, thermal behavior, volatile or semi-volatile components, and other formulation characteristics. The scope can be tailored to the specific competitive question.
Can Materials Metric investigate why a cosmetic product changed or failed?
Yes. Changes such as separation, discoloration, residue formation, precipitation, odor, or texture may be investigated using a combination of analytical techniques. The goal is to identify measurable differences and develop evidence-based hypotheses for the observed behavior.
