Rheology Analysis

With the development of the cosmetics industry, there are many types of cosmetic formulations, and most of the cosmetic systems are heterogeneous and indeterminate structures. Cosmetic products that usually exist in the form of emulsions, suspensions, etc., among them, the component compatibility, phase state, process conditions and storage conditions have an impact on the stability, quality and performance of the product. The characteristics required for the properties by many cosmetics include: emulsion stability, spreadability, suspension, thermal stability, extrudability, thickening effect, etc.

Since many cosmetic emulsions are non-Newtonian fluids, they often have complex shear and time-related characteristics. This means that from the beginning of production to entering the market, the viscosity of emulsion cosmetics changes with the changes in the applied shear stress. Therefore, the “history of the shear stress of cosmetics” becomes very important. What often needs to be controlled is not only viscosity, but all rheological properties. In addition to viscosity, it also includes plastic change value, stress-dependent relationship, and time-dependent relationship, etc.

Creative BioMart can provide rheology analysis services to analyze the micro-rheological properties of samples. Using our analyze methods, we can understand the characteristics of cosmetics, so as to identify cosmetic raw materials and intermediate products and control the production process.
