This Extrait de Perfume Formulation module explains how to make high-quality perfumes with a fragrance oil concentration of 20–40%, which produce a long-lasting and luxurious scent. This module distinguishes between different types of perfumes based on their essential oil content, such as Extrait de Parfum, Eau de Parfum, Eau de Toilette, Eau de Cologne, and Eau Fraiche. Complete with explanations of the laboratory and industrial tools used, this module also presents three perfume formulation examples: Fresh Aromatic, Sweet Floral, and Sweet Gourmand. Each formula consists of top notes, middle notes, and base notes that are arranged to create a balanced aroma. The manufacturing process involves gradual mixing from base to top notes, dissolution with alcohol, and a 48-hour curing stage to allow the aromas to blend perfectly. This module emphasizes the importance of proper mixing techniques, selecting high-quality ingredients, and storing the perfume in a cool, dark place to maintain its stability and character.
