Physicochemical Testing
What is Physicochemical Testing?
Physicochemical analysis characterizes a cosmetic formula’s composition, structure and physical behavior. This category brings together targeted measurements of active content, particles, pH, flow and molecular features, alongside broader property-testing programs.
Why do you need this service?
Use physicochemical characterization to compare formula composition and behavior during development or quality investigation. Selected measurements can inform specifications and stability studies without establishing shelf life on their own.

Physicochemical analysis services
Characterization establishes what a formulation contains and how it behaves. It supports formulation development, specifications and interpretation of later stability or performance studies. Select a targeted method when the question is narrow, or a coordinated analytical program when several properties need investigation.
Composition and structure
Active ingredient quantification measures selected compounds and can track their concentration during storage. Microscopic analysis examines droplets, crystals and dispersion structure to help explain visible or textural changes.
Particles and flow
Particle size distribution analysis characterizes the size range of a dispersed phase using a method appropriate to the material. pH and viscosity profiling measures acidity and flow behavior under defined conditions, providing useful indicators of batch consistency and change over time.
Broad property testing and molecular evidence
The individual physicochemical analysis service combines selected bulk-property measurements into a broader workup. Spectroscopic characterization adds chemical fingerprints or information about molecular features and interactions where the technique can resolve them.
These results inform formulation development by identifying measurable targets and explaining why prototypes differ. Characterization alone does not establish clinical efficacy, safety or shelf life.

Applications of physicochemical testing
Choosing targeted measurements
Active quantification can investigate a selected compound, microscopy can examine dispersion structure, and particle sizing can characterize a relevant dispersed phase. pH and viscosity measurements should state conditions because temperature, method and handling affect the result.
Explaining prototype differences
Spectroscopy and broader property testing can help investigate an unexpected batch or storage change. These results can guide reformulation and the design of subsequent stability or performance studies. Characterization is not a universal preclinical stage and does not itself validate clinical efficacy, safety or long-term stability.
