Pigments, dyes, and adsorbents: Structures and characteristics

This teaching unit is dedicated to acquiring knowledge related to pigments, dyes, and adsorbents, from the perspective of their structures and applications. Emphasis will be placed on applications in the field of flavors & fragrances (food coloring, perfumery) and cosmetics (hair coloring, powders, toothpaste, etc.). Some sessions are specific to each of the two tracks (P1, Cosmetics Engineering; P2, Flavors and Fragrances) of the Master's degree in Chemistry, specializing in Cosmetics, Flavors, and Fragrances Engineering (ICAP). The teaching unit includes lectures and tutorials.

Hourly volumes:

CM: 10 a.m.

Tutorial: 10 a.m.

The objective of this course unit is to provide students with knowledge in the field of dyes, pigments, and adsorbents in order to understand the issues associated with the specialty field of cosmetics, flavor, and fragrance engineering. The objectives are as follows:

• Know how to identify the chemical classes to which dyes and pigments belong
• Understand the link between chemical structures and colors, as well as the types of chromic phenomena (halochromism, photochromism, thermochromism).
• Know how to use Colour Index data (generic name, constitution number, etc.).
• Know the regulations associated with pigments and dyes in the areas of specialization of the ICAP Chemistry Master's degree.
• Understand and be able to characterize the physical and chemical properties of powders used in the field of specialization of the ICAP Chemistry Master's degree.

Bachelor's degree in Chemistry (Organic Chemistry, Materials Chemistry, Life Sciences Chemistry, Physical Chemistry)
