In perfumery, a fixative is a substance used to stabilize and prolong the scent of a fragrance. It slows down the evaporation of volatile components, ensuring the perfume maintains its character and lasts longer on the skin.

🌿 Types of Fixatives

• Natural fixatives — Resins (benzoin, labdanum), balsams (tolu, peru), woods (sandalwood, cedar), and animalic notes (musk, ambergris, civet).
• Synthetic fixatives — Compounds like phthalates, ambroxan, galaxolide, and Iso E Super, designed to mimic natural fixative properties.
• Musk fixatives — White musks and nitro musks (historically used, now largely replaced for safety reasons).

⚙️ Role in Fragrance Oils

• Stability — Prevents rapid evaporation of lighter notes.
• Longevity — Extends wear time on skin and fabrics.
• Balance — Helps harmonize top, middle, and base notes.
• Projection — Enhances diffusion and sillage of the fragrance.
