Des Solutio – Scientific Consulting Solutions Lda. is a NOVA University spin-off company that arises from the need to respond to several requests for scientific advice in research and development, in the field of green chemistry and sustainable development, namely through the use of a new generation of solvents known as eutectic solvents (DES – Deep Eutectic Systems).

Mission & Vision

Our mission is to offer integrated consulting services that contribute to the development of value-added products for our customers.

DES Solutio intends to establish its presence in the international context as a reference company in the area of eutectic solvents and intends to be the first to market these natural-based solvents for research and development.

We intend to value the knowledge generated in academia, promoting the bridge between research and industry and streamlining marketing processes. It is also the company’s objective, in collaboration with other research centers, to contract research and development services at a laboratory level that may be required by the companies that contact us.

We envision a greener and more sustainable future, where the toxic solvents used in the majority of processes could be replaced by natural alternatives.

Social Responsibility

Des Solutio conducts its business in a transparent and ethical manner, being concerned with social, cultural, economic and environmental issues. Through its work, the company intends to have a positive impact on society, in order to achieve sustainability in all its activities, and a positive impact on the planet, due to the aim of globalizing the use of natural solvents in several areas. In addition, there is a concern about people and their well-being, through proper and fair operating practices.



Nature is the most plentiful source of compounds. Many of these compounds (vitamins, phenols, flavonoids, antioxidants) have been used in different applications for long time, namely for nutritional, cosmetic or pharmaceutical purposes, where the main extraction process was commonly based on the use of organic solvents. The problem is that these solvents have a harmful effect on health and environment, due to its toxicity. In this context, safety regulations are getting tighter and companies are looking for “greener” alternatives, while consumers demand for organic products.

Des Solutio aims to explore natural solvents bio-inspired in nature – the natural Deep Eutectic Solvents (NADES). These are mixtures of two or more naturally occurring chemical components that, when combined at a particular molar ratio, become liquid at room temperature. Nearly 106 combinations of natural DES could be envisaged and the possibilities that arise from the ability to tailor new solvents with the most adequate properties for a given application are huge.

Des Solutio’s team has built over time a set of DES libraries where each DES is targeted to a particular application. The company is focused in the development of new NADES for:

  • Extraction
  • Cosmetics
  • Pharmaceutics

If your company is interested in any of these applications and would like to discuss the feasibility of process implementation, please contact us.
