Laboratory rheological analysis: characterization of mechanical and textural properties
Optimize the texture and stability of your products using rheology
Rheological analysis is essential for understanding and optimizing the behavior of materials under stress. Whether ensuring the stability of a cosmetic emulsion, adjusting the viscosity of a liquid food supplement, or optimizing the texture of a food product, this expertise is crucial.
YesWeLab provides you with a network of specialized laboratories , capable of accurately assessing the viscosity, elasticity, consistency and thixotropy of your formulations. Thanks to cutting-edge instruments such as the rotational rheometer, the capillary viscometer or the creep test , we help you control the shaping, transformation and use of your raw materials or finished products.
What rheological analyses should be carried out in the laboratory?
Our laboratories carry out studies adapted to the needs of your sector, including:
- Measurement of dynamic and kinematic viscosity for Newtonian, pseudo-plastic or dilatant behaviors. These analyses make it possible to evaluate the resistance to flow of a fluid as a function of the applied stress, essential for optimizing the formulation and implementation of products.
- Viscoelastic behavior via oscillation analysis : This technique measures the response of a material subjected to periodic deformations, which is crucial for characterizing gels, creams, polymers and other substances with both solid and liquid properties.
- Flow curves and stress threshold : these determine the stress at which a product begins to flow, a key parameter for adapting the transport, storage and application conditions of viscous or pasty products.
- Stability of emulsions and gels : phase separation test . This analysis evaluates the tendency of a mixture to separate phases over time, which is essential to ensure the shelf life and effectiveness of cosmetic, food and pharmaceutical formulations.
- Powder rheology : density, flow, compressibility.
These parameters influence the storage, shaping and homogeneity of powders in industrial processes, particularly for the food, pharmaceutical and chemical industries.
- Texture of finished products : penetration, firmness, and cohesion tests. These tests assess the sensory and mechanical properties of products, such as the flexibility of a cream, the strength of a tablet, or the consistency of a food.
