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 it's to guarantee the stability of a cosmetic emulsion, adjust the viscosity of a liquid food supplement, or optimize the texture of a food product, this expertise is crucial.
YesWeLab provides you with a network of specialized laboratories capable of accurately evaluating the viscosity, elasticity, consistency, and thixotropy of your formulations. Using cutting-edge instruments such as the rotary rheometer, capillary viscometer, and creep tester , we help you master the shaping, processing, and use of your raw materials or finished products.
What rheological analyses should be performed in the laboratory?
Our laboratories conduct studies tailored to the needs of your sector, including:
- Measurement of dynamic and kinematic viscosity for Newtonian, pseudo-plastic, or dilatant behavior. These analyses allow for the evaluation of a fluid's resistance to flow as a function of applied stress, essential for optimizing product formulation and implementation.
- 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 at what stress a product begins to flow, a key parameter for adapting the transport, storage and application conditions of viscous or pasty products.
- Emulsion and gel stability : phase separation test . This analysis assesses the tendency of a mixture to separate over time, which is essential to guarantee the shelf life and efficacy 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 test, firmness, cohesion. These tests allow for the evaluation of the sensory and mechanical properties of products, such as the suppleness of a cream, the resistance of a tablet, or the consistency of a food.
