Description

This course is designed to introduce students to concepts related to pigments, dyes, and adsorbents, focusing on their structures and applications. Emphasis will be placed on applications in the fields of flavors and fragrances (food coloring, perfumery) and cosmetics (hair coloring, powders, toothpaste, etc.). Some sessions are specific to each of the two tracks (P1, Cosmetic Engineering; P2, Flavors and Fragrances) of the Master’s in Chemistry with a specialization in Cosmetic, Flavor, and Fragrance Engineering (ICAP). The course unit consists of lectures and tutorials.

Hourly volumes*:

CM: 10 a.m.

TD: 10 a.m.

Objectives

The purpose of this course unit is to provide students with knowledge in the field of dyes, pigments, and adsorbents so that they can understand the related issues in the specialized field of cosmetics, flavors, and fragrances engineering. The objectives are as follows:

  • Be able to identify the chemical classes to which dyes and pigments belong
  • Understand the relationship between chemical structures and colors, as well as the types of color-changing phenomena (halochromism, photochromism, thermochromism).
  • Know how to use data from the Colour Index (generic name, constitution number, etc.).
  • Understand the regulations governing pigments and dyes in the specialized fields covered by the ICAP Master's in Chemistry program.
  • Understand and be able to characterize the physicochemical properties of powders used in the specialized field of the ICAP Master’s in Chemistry.
