Ingredients and Raw Materials in Perfumery: Complete Guide to Aromatic Components

Definition of Raw Materials in Perfumery

The aromatic raw materials are all the components used to create fragrances, classified into two main categories: natural (extracted from plants, flowers, woods, resins, and animal substances) and synthetic (molecules created in the laboratory). These ingredients make up the perfumer's palette, determining the character, quality, and olfactory properties of each fragrance.

Importance in Modern Perfumery

  • Aromatic diversity: More than 3,000 ingredients available
  • Constant innovation: New synthetic molecules every year
  • Sustainability: Eco-responsible alternatives to scarce ingredients
  • Consistency: Uniform quality in mass production

Main Classification of Ingredients

1. Natural Ingredients (60% of the market)

Essential Oils

Definition: Volatile essences extracted from aromatic plants by steam distillation.

Main characteristics:

  • Obtained by physical methods (without chemical alteration)
  • Complex composition (50-300 different molecules)
  • Natural variability depending on origin and harvest
  • Biodegradable and renewable

Main essential oils:

  • Rose - The queen of flowers, available as essential oil and absolute
  • Lavender - Versatile aromatic, relaxing and fresh
  • Bergamot - Elegant citrus, base of colognes
  • Neroli - Orange blossom, delicate and sophisticated

Absolutes

Definition: Concentrated extracts obtained by solvent extraction, preserving maximum aromatic fidelity.

Obtaining process:

  1. Extraction with hexane → Concrete
  2. Extraction with alcohol → Absolute
  3. Final concentration: 95-99% aromatic purity

  • Historical revolution: They transformed perfumery in the 20th century

Synthetic Musks

Musk - Family of warm and sensual molecules.

  • Evolution: From animal origin to synthetic for sustainability
  • Types: White musks, macrocyclics, nitro-musks
  • Function: Fixation, sensuality, skin note

Aquatic Molecules

Innovation of the 90s that created the aquatic family.

  • Calone: Marine molecule that evokes ocean breeze
  • Cascalone: Softer aquatic freshness
  • Ozonic molecules: Recreate the scent of air after rain

Fruity Molecules

Synthetic recreation of fruit aromas impossible to extract.

  • Apple: Molecules that recreate fresh Green apple
  • Pear: Juicy and refreshing notes
  • Red fruits: Synthetic raspberry, strawberry, currant
