Innovative bioinspired solvents named MINAC, LTTM or NADES, appeared in the scientific literature now 20 years ago. These natural solvents are formed by combining two or more natural compounds, such as organic acids, sugars, or amino acids, interacting through weak bonds (like hydrogen bonding) to create stable, biodegradable, and often biocompatible solvents. In the cosmetic field, this new class of solvents is gaining attention as a sustainable alternative to certain controversial organic solvents, offering a more environmentally friendly and potentially more skin-compatible option. They enable the extraction and solubilization of delicate natural actives (such as antioxidants, vitamins, and polyphenols) while preserving their integrity and biological activity. Additionally, their ability to penetrate the skin’s superficial layers makes them promising vectors for delivering active ingredients more effectively. Overall, these solvents contribute to developing more sustainable and potentially more efficient cosmetic products, aligning with consumer demand for more natural and eco-friendly products. This workshop will present these new solvents, their potential as cosmetic ingredients, but also the currents limitations and PI aspects.
