Theme 1.2: Innovative and Sustainable Cosmetic Forms and Ingredients

Objectives

In a context of sustainable transition of industry (SSbD european framework):

• Develop innovative formulas, nano- or non-nano, mainly based on dispersed systems
• Develop innovative preparation processes
• Better understand the molecular interactions occurring within complex formulas and between the skin and the formulas

Summary

The research activities of this theme concern formulation and manufacture of liquid and semi-solid dosage forms (solutions, emulsions, suspensions, gels, creams, films, foams).

Our team has an expertise in nanoencapsulation (alginate nanocapsules, lipid nanocapsules, stimuli-responsive polymeric nanosystems) as well as in incorporating the nanosystems into finished products for cutaneous application.

We pay attention for physicochemical characterization of nanosystems and final dosage forms using a large spectrum of techniques.

We also evaluate the formulations for their potential toxicity and determine skin penetration of active molecules (cell cultures, reconstructed skin, human skin biopsies in diffusion cells).

Current work particularly concerns the incorporation into formulas of new multifunctional ingredients: natural deep eutectic solvents (NaDES).
