3. Conclusion and outlook

The success of innovations in the field of cosmetic active ingredient extraction, in terms of discovery, intensification and sustainability, is the result of the accumulation of academic and industrial know-how in the fields of physics, biology, process engineering and natural product chemistry. Eco-extraction" of cosmetic active ingredients is a new concept that meets the challenges of the 21st century: protecting the environment and consumers. In this eco-extraction approach, the concept of eco-extract could be introduced. It would be an extract obtained and marketed in such a way as to be the fruit of an entire value chain in both senses of the term: economic and eco-responsible. This chain would begin with harvesting, continue through the transformation, extraction and separation processes, and end with the formulation and marketing stages.
