7. Perfume Ingredients and Sources:

Perfume ingredients come from both natural and synthetic sources. Here’s a breakdown:

Natural Ingredients:

• Essential Oils: These are extracted from plants, flowers, and fruits through methods like steam distillation or cold pressing. Examples include rose oil (from petals), bergamot (from citrus rind), and lavender.
• Absolutes: These are concentrated, highly aromatic oils extracted through solvent extraction. Commonly used for delicate flowers like jasmine and tuberose, which are too fragile for steam distillation.
• Resins and Balsams: These sticky substances come from trees and plants, like frankincense, myrrh, and benzoin. They add depth and warmth to perfumes, often used in base notes.
• Animalic Ingredients: Historically, perfumes used substances from animals for their strong, long-lasting qualities. These include ambergris (from whales), civet, and musk (from deer). Today, animal-derived ingredients are largely replaced with synthetic alternatives due to ethical concerns.

Synthetic Ingredients:

• Aroma Chemicals: These are lab-created molecules that mimic or enhance natural scents. Some aromas cannot be effectively extracted from nature (like lily of the valley), so synthetics replicate those scents. Synthetic molecules can also stabilize or enhance the longevity of a perfume.
• Iso E Super: A popular synthetic molecule that has a velvety, woody-amber scent. It is often used to add smoothness and roundness to a fragrance.
• Calone: A synthetic used to impart fresh, marine-like notes, often used in aquatic fragrances.

8. Fragrance Development Stages:

Perfume creation is a highly complex and creative process that involves several stages:

a. Concept Development:

This is the initial step where the brief is created. A perfumer, also called a nose, will gather inspiration and ideas based on the desired mood, setting, or story for the fragrance. This can include a season, a place, or an emotion.

b. Scent Composition:

Perfumers combine raw materials in different proportions to create a balance between the top, heart, and base notes. This stage requires immense knowledge and experience in how individual ingredients interact.

Perfume creation is like blending music – each note must harmonize with others to create a complex and appealing composition. They will typically start with a core accord, which is a harmonious blend of ingredients forming the perfume’s “skeleton.”

c. Testing & Tuning:

Once the initial formula is created, it’s tested on skin and strips to observe how the scent evolves over time. The perfumer may make adjustments, tweaking the formula to refine the balance or improve longevity.

d. Maceration:

After blending, the perfume undergoes maceration, a process where the mixture is allowed to “rest” for several weeks. This allows the ingredients to fully meld, deepening the scent. Similar to wine, perfumes can mature and improve over time during maceration.

e. Stabilization and Bottling:

After maceration, perfumes are filtered to remove any impurities, then packaged. Some perfumes are further diluted before bottling, depending on the desired concentration (e.g., EDP, EDT).
