Descriptions

Comment (FraterWork)

Syringa aldehyde opens with a strong, sweet floral-green burst—immediately recognisable as the honeyed, powdery heart of lilac blossom. It shares the phenylacetaldehyde family's floral-green intensity but arrives with less pungency and more warmth. Beneath the floral top, a soft animalic facet and mimosa-like sweetness give it a living, breathing quality. This is one of the essential building blocks for lilac accords, where it provides the warm, honeyed-floral depth that hydroxycitronellal and terpineol alone cannot achieve. Use it in hyacinth bases for green-floral impact, in rose accords for added freshness, and in mimosa compositions where its powdery sweetness enhances the honeyed character. It also brings a gentle animalic warmth to white florals—think indolic without the indole. SYRINGA ALDEHYDE VS PHENYL ACETALDEHYDE [https://fraterworks.com/products/phenyl-acetic-aldehyde] These two aldehydes are easy to confuse, but they occupy very different olfactory spaces. Phenyl acetaldehyde is the powerhouse of the two—an overwhelmingly intense green-floral hyacinth note with harsh, almost aggressive pungency at full strength that softens into honeyed, chocolatey sweetness on extreme dilution. It is the sharpest and greenest of the three, and demands careful dosing at fractions of a percent. Syringa aldehyde sits in the middle: it is structurally a phenylacetaldehyde with a methyl group added to the para position of the ring, which softens the harshness dramatically. The result is warmer, more honeyed, and more powdery—recognisably floral-green but without the aggressive bite, making it far easier to work with in lilac and mimosa accords. aromachem Best Seller
