SOLCALC Software – Frequently Asked Questions

Overview & Capabilities

  • What is the SOLCALC software?

SOLCALC software is an Excel-based add-in specifically engineered for drug formulation applications. It facilitates a broad variety of PC-SAFT calculations, including classical phase equilibria and metastable states, and assesses the impact of humidity on formulation stability. Additionally, it enables the evaluation of glass transition temperature (Tg), wet Tg, shelf life, and molecular mobility. This tool is instrumental in the digital design of drug formulations, providing a robust platform for comprehensive formulation analysis.

  • What can the software calculate?

The software offers a comprehensive range of calculations essential for drug formulation. It provides analyses for amorphous solid dispersion (ASD) phase diagrams, humidity effects, water sorption, phase separation, and both glass transition (Tg) and wet Tg temperatures. It evaluates the shelf life of ASDs, determines miscibility, and includes customized functions for advanced calculations (e.g. thermodynamic activities, fugacities) that can lead to complexer calculations like an entire spray drying processes (encompassing assessments of residual solvent, solvent accumulation during drying, and enabling virtual design of experiments).

SOLCALC is designed to perform calculations on a standard PC with ordinary hardware specifications, allowing analysis of complex mixtures without requiring specialized equipment. This efficiency ensures that users can obtain comprehensive insights quickly and effectively.

  • How do you ensure the security and privacy of data?

We prioritize the security and privacy of your sensitive information. SOLCALC ensures that all data remains local on your device, with no communication between the software and our servers. This policy guarantees that your data is not stored or processed in the cloud.

  • How much does the SOLCALC software cost?

For detailed pricing information on SOLCALC software, we invite you to contact us directly. The software is offered through a 1-year subscription model, emphasizing our dedication to continuous innovation and consistent updates. Our team is committed to understanding your specific needs and will provide you with a customized offer tailored to your requirements.

Applications & Further Information

  • Can SOLCALC handle complex formulations and diverse excipients? 

Yes, the software is equipped with built-in capabilities for rigorous modeling of complex formulations, including lipid-based formulations, ternary amorphous solid dispersions (ASDs) and surfactant-containing ASDs. Its versatility allows for the analysis of a wide range of components within any formulation. The software further supports a wide range of excipients, such as sugars, lipids, amino acids, among others. Numerous publications demonstrate the benefits of this modeling approach.

  • What happens if a compound of interest is not in the database?

We have strategies to characterize unknown material and can do the parameter fit for these compounds (e.g. a polymer: fitting to vapor sorption data) with limited amounts for training data sets. Additionally, new excipient grades can be considered. Our approach is validated by practical applications and publications, including a notable collaboration with the excipient supplier Nisso Chemical. Read the publication here.

  • What kind of training data is required?

The software requires only few data points to effectively train the model for a new substance, typically as few as 5 solubility measurements in organic solvents. This is significantly less data than what is usually needed for AI/ML tools. Its robustness stems from a solid physical foundation that describes intermolecular interactions, ensuring accuracy and reliability with minimal input.

  • Are there updates available for the software?

Solcalc is constantly updated, expanded to incorporate newly characterized compounds and integrated with new functions. This ongoing development is especially relevant for users interested in different grades of excipients or in comparing offerings from various suppliers. By choosing SOLCALC, you can be confident utilizing a software that is kept up-to-date with the latest characterizations and data, facilitating informed decisions and enhanced research outcomes.
