The distribution of compounds between the gas phase, various liquid or colloidal phases and adsorption to interfaces is of crucial importance for the flavor and fragrance industry as well for the production and extraction processes. While flavor and fragrance compounds are typically small or medium-sized molecules, many of them have demanding and unusual stereochemistry and ring structures. For these molecules, we offer one of the best prediction tools for partitioning, vapor pressures and liquid-liquid extraction on the market.
- Liquid extraction prediction
- Vapor liquid equilibria estimation for distillation purposes
- Screening for the best solvents, cosolvents or entrainers
- Total or partial vapor pressure prediction without use of experimental data
- Prediction of flash points for pure compounds and mixtures
- Estimation of fragrance adsorption to cloth or hair or other materials
Vapor pressure (VP)
COSMOtherm can predict the vapor pressures and their temperature dependency for pure compounds and mixtures even without experimental data. If available, experimental VP data can be used to enhance the accuracy of the predictions. Use COSMOtherm to design new compositions, to optimize the development, or to provide temperature and composition-dependent pressure data (VP(T,x)) to your customers.
Extraction & distillation
Choose the most effective solvent and conditions for your extraction or select cosolvents and entrainers for distillation. Apply our modules for the modelling of liquid extraction, liquid-liquid-equilibrium, liquid-vapor-equilibrium or solvent screening to design and optimize your technical processes.
Adsorption & adhesion
Measuring the adsorption or adhesion of fragrance compounds can be a difficult and time-consuming task. Use our tools to build simple and effective models to predict the adsorption to about any material. Knowing the different air-material partition coefficients of your fragrance compounds will provide insight into the olfactory changes when transferred to different matrices.
