Pigments, dyes and adsorbent: Structures and characteristics

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.

Hourly volumes* :

CM : 10 h

TD : 10 h

The objective of this course is to provide students with knowledge in the field of dyes, pigments and adsorbents in order to understand the associated problems in the field of cosmetics, flavors and fragrances engineering. The objectives are as follows:

• Know how to identify the chemical classes to which dyes and pigments belong
• To know the link between chemical structures and colors, as well as the types of chromic phenomena (halochromism, photochromism, thermochromism).
• Know how to use the Colour Index data (generic name, constitution number, ...).
• To know the regulations associated with pigments and dyes in the fields of specialization of the ICAP Chemistry Master.
• To know and know how to characterize the physico-chemical properties of powders used in the field of specialization of the ICAP Chemistry master.
