Viscosity determination

Viscosity analysis is an essential method for assessing the flow resistance of a liquid or fluid. This key parameter strongly influences the stability, usability, and industrial processing of many products. It is applicable to the food, cosmetics, nutraceutical, animal nutrition, and technical formulation sectors.

Objectives of the analysis

The analysis aims to:

• Determine the dynamic viscosity of a fluid (in cP or mPa·s)
• Control the consistency and texture of a product
• Track batch variations in production
• Optimize the formulation (stability, rheology, application)
• Validate compliance with technical specifications

Available analytical techniques

• Brookfield Viscometer : Standard measurement at defined temperature and speed
• RVA (Rapid Visco Analyzer) : rapid consistency test, ideal for production
• Capillary or falling ball viscometer : measures according to density or gravity
• Rotational rheometer (on request): for advanced analysis of shear behavior

Measured parameters

• Dynamic viscosity (in mPa·s or cP)
• Thixotropy (variation with time and shear)
• Apparent and real viscosity
• Measuring temperature, flow curves (optional)

Affected matrices

• Cosmetics: creams, gels, lotions, shampoos
• Food industry: sauces, syrups, purees, drinks
• Nutraceutical: liquid plant extracts, suspensions
• Animal nutrition: porridges, pasta, nutritional gels
• Industrial products: inks, paints, glues, solvents, technical sludge

Industrial applications

• Quality control in production line
• Development and validation of new formulations
• Regulatory or marketing compliance (texture, appearance, performance)
• Stability study of products sensitive to temperature or shear variations
