Water Conductivity Testing
At ISCA Cosmetic Testing, we offer precise water conductivity testing to assess the ionic content of aqueous solutions and cosmetic formulations. Conductivity measurement is a vital quality control step for water-based products, helping to ensure consistency, purity, and compliance with formulation specifications.
Using calibrated, industry-standard equipment, we determine the electrical conductivity of your sample in micro siemens per centimetre (µS/cm), providing an accurate indication of dissolved salts, ions, and other conductive materials present. This service is particularly valuable for:
Formulation development – verifying water quality before blending.
Quality assurance – ensuring batch-to-batch consistency.
Regulatory compliance – meeting purity requirements for raw materials and finished products.
Troubleshooting – identifying potential contamination or formulation instability.
Our experienced technical team delivers fast turnaround times, clear reporting, and guidance on interpreting results to help you maintain product integrity and performance.
Ideal for: aqueous-based cosmetics, personal care products, raw material testing, and purified water systems.
E.g. Batch number, formulation number etc. This is to allow us to uniquely identify your sample in our laboratory.
This should correspond to the label on your sample.
