Natural active ingredients and additives

This module is dedicated to the study of the main classes of cosmetic additives, as well as natural, biotechnological and synthetic active ingredients.

The first part of this course will focus on marine flora, with particular emphasis on the general composition and specific characteristics of different algae. What is the role and effectiveness of marine flora in cosmetics?

The course will conclude with case studies and perspectives.

A second part will focus on the plant world, enabling formulators and those in charge of regulatory affairs to understand how plant molecules are used for their beneficial effects in relation to the main cosmetic indications. Essential oils: what are their production techniques, chemical compositions, cosmetic properties, formulation and safety of use?

The third part of the module will focus on the different classes of additives used in cosmetics.

Emphasis will be placed on the chemical and organoleptic study of the main raw materials (synthetic or natural) used in cosmetics perfuming, and the regulatory constraints linked to their use (cosmetics directives on allergen dosage).

The families of fragrance molecules used in cosmetics (molecules with no organic function or containing alcohol, aldehyde, ketone or ester functions) will be studied:
- molecules with an aromatic ring
- phenol-type molecules
- cyclic and acyclic aliphatic molecules.
- acyclic and cyclic terpene molecules
- odor field.

-Notions of stability and volatility of molecules.

The course concludes with an apprenticeship in the formulation of fragrance compositions for cosmetic products.
