M1 - Flavors & Fragrances (ICAP P2)

This teaching unit is dedicated to the acquisition of notions related to pigments, dyes and adsorbents, from the point of view of their structures and their applications. Emphasis will be put on applications in the field of flavors & fragrances (food coloring, perfumery) and cosmetics (hair coloring, powders, toothpastes...). Some sessions are specific to each of the two courses (P1, Cosmetics Engineering; P2, Flavors & Fragrances) of the Master's degree in Chemistry specializing in Cosmetics, Flavors and Fragrances Engineering (ICAP). The UE includes lessons given in lectures and tutorials.

Some fundamental basics of microbiology will be covered so that students have an overview of the diversity of microorganisms. The mode of nutrition and multiplication of bacteria according to the physico-chemical parameters of the environment will be studied.

The composition and role of the skin and digestive microbiota will be discussed.

The microbiological criteria used for the quality control of cosmetic and food products will be defined.

Physical and chemical antimicrobial agents to control microbial growth will be reviewed.

At the practical level, the student will be expected to know how to handle bacteria and to know the rules of microbiological safety. Usual techniques of microbiological controls and effectiveness of preservatives will be performed on cosmetic products.

This EU addresses:

- the foundations of colorimetry, which allow to define an unambiguous measure of color from psychophysical experiments.

- the principle and practical use of color measuring devices (colorimeters and spectro-colorimeters).

- the principles of color reproduction, particularly in the context of perfumes and cosmetics.

Theoretical ideas are complemented by an important part of observation and manipulations during the practical sessions.

The professionalization project provides a link between the traditional practical work and the internship in a laboratory or company. It is carried out in the form of a tutored project consisting of putting the student in a professional situation through collaborative (group) work based on the realization of a project in response to a problem set by a company, community, association or academic. It is part of the core curriculum of the Chemistry Master's program and is carried out under the responsibility of a member of the teaching team (university or industry). Carried out throughout the semester, this project aims to relate and anchor the knowledge/know-how acquired in the framework of the Bachelor's degree and the beginning of the Master's degree through this professional situation. These situations will be directly linked to the Master's program chosen by the students. In addition to the disciplinary skills of chemistry, other relational, organizational and communication skills, intrinsically linked to project management, will also be acquired and will arm the students for their future professional life.

Answer a research problem: example of synthesis of new phosphorescent materials.
