Viscosity dosage

Viscosity analysis is an essential method for evaluating a liquid's or fluid's resistance to flow. 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 : measurement based on density or gravity
• Rotary rheometer (on request): for advanced shear behavior analysis

Measured parameters

• Dynamic viscosity (in mPa·s or cP)
• Thixotropy (variation as a function of time and shear)
• Apparent and actual viscosity
• Measurement temperature, flow curves (optional)

Affected matrices

• Cosmetics: creams, gels, lotions, shampoos
• Food processing: sauces, syrups, purees, drinks
• Nutraceuticals: liquid plant extracts, suspensions
• Animal nutrition: porridges, pastes, nutritional gels
• Industrial products: inks, paints, glues, solvents, technical sludges

Industrial applications

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