pH value analysis measures how acidic or alkaline a product is. Pentyl Labs performs this testing using ASTM E70, which describes direct pH measurement with a calibrated electrode. This method applies to liquids, semi-solids, and water-based formulations.
pH plays a key role in product quality. Therefore, manufacturers monitor pH to ensure products remain stable, safe, and consistent.
pH affects ingredient compatibility, product appearance, and overall performance. In addition, pH changes may signal instability, contamination, or formulation drift. For this reason, routine pH testing helps manufacturers detect issues early.
Many cosmetic, personal care, and cleaning products must stay within defined pH ranges. As a result, pH testing supports both internal specifications and external expectations.
ASTM E70 uses direct electrochemical measurement. First, the laboratory calibrates the pH meter using certified buffer solutions. Next, the analyst measures the sample under controlled conditions.
This approach delivers accurate and repeatable results. Moreover, it works well across many product types when proper calibration and handling are used.
Manufacturers apply pH value analysis to cosmetics, personal care products, cleaning formulations, raw materials, and finished goods. Testing often occurs during formulation development or reformulation.
Additionally, pH testing supports stability and compatibility studies. By tracking pH over time, manufacturers can spot trends that may affect shelf life or performance.
Manufacturers use pH data to confirm that products meet specifications. Furthermore, results support quality control programs, batch release decisions, and customer documentation.
pH testing often works alongside Chemical Analysis Services and Stability and Compatibility Testing. Together, these services provide a clearer picture of formulation behavior.
Overall, pH value analysis provides essential insight into product quality and consistency. ASTM E70 offers a reliable method for direct pH measurement. As a result, manufacturers gain confidence in product performance, stability, and quality control.
