Synthetic Middle Notes

Hedione (methyl dihydrojasmonate) – A jasmine-like molecule with sheer, dewy floral character and radiant diffusion. Not powerful in scent but dramatically increases lift and sillage of compositions. Used in almost all modern florals, especially for mimicking natural freshness.

Aldehyde C-14 (peach lactone) – Milky, fruity-amber material with a creamy peach skin impression. Adds softness, warmth, and a gourmand touch to floral and fruity hearts. Often found in peach, apricot, and osmanthus-type accords.

Rosalva – Clean, rich, warm rose alcohol with soft floral and green effects. Used as a synthetic rose booster with excellent stability and volume. Useful in creating abstract floral hearts or supporting naturals.

Lilial (now mostly replaced with substitutes like Lysmeral) – Soft, powdery floral with green, lily-of-the-valley and muguet notes. Often used to bring floralcy and volume to soap-like accords, floral bouquets, and musky blends.

Florol (also called Moskenox) – Transparent, elegant muguet floral with a dewy, clean character. Great for building watery florals and softening harsh edges in the heart.

Phenyl Ethyl Alcohol (PEA) – Rosy, honeyed, slightly green. Though naturally derived, it's mostly used in synthetic form. Acts as a supporting floral heart that smooths and rounds other materials, especially rose and carnation.

Helional – Fresh, aquatic-floral with green and metallic facets. Key for marine accords and ozone-clean compositions, often used to give watery lift and brightness to synthetic florals.

Methyl Ionone Gamma – Powdery, woody-floral violet material with soft tea and iris nuances. Gives a soft, elegant character to heart notes and is essential in iris, violet, and woody floral blends.

Lyral (now replaced with safe substitutes like Lilyflore) – Fresh, lily-like floral with powdery nuances. Often used in muguet accords and to add light floralcy without dominating the heart.

Auralva (or similar jasmine-type materials) – Transparent synthetic jasmine with clean, radiant lift and no animalic undertones. Used when a crisp white floral presence is needed in modern or minimalist compositions.

Cyclamen Aldehyde – Fresh, watery, slightly green floral with metallic edge. Boosts diffusion and provides crispness to soft florals, often used in spring-themed or aquatic heart accords.

Aldehyde C-18 (coconut lactone) – Creamy, tropical, and sweet with a strong milky-coconut impression. Adds a gourmand, sunny dimension to florals, especially when used in ylang, gardenia, or tuberose blends.

Calone – Marine, watermelon-like, and slightly floral. Extremely diffusive; used at trace levels in heart notes to build transparent, breezy florals and aquatic compositions.

Exaltolide / Habanolide – Musks that can radiate from the heart depending on structure. They provide a soft, skin-like, clean backdrop that enhances other materials and boosts longevity and texture.

Indole – Animalic, jasmine-derived molecule used at very low doses to dirty up and enrich white florals. Adds depth, mystery, and an old-school French perfumery signature to the heart.

Cassyran – Green, fruity-blackcurrant note with strong diffusion. Replaces or enhances natural cassis and adds juicy, sharp realism to florals and fruity florals.

Methyl Anthranilate – Grape-like, fruity, with a floral-orange blossom edge. Often used in orange blossom, neroli, or exotic floral blends. Can lend a nostalgic or playful sweetness to the heart.

Lactones (various types: C-10, C-12, Gamma-undecalactone, etc.) – Milky, creamy, and fruity depending on size. Used to bring creaminess and body to white florals, fruity florals, and gourmand blends.
