LYRAL TOCO IFF – floral, sweet and creamy note with hints of lilac, lily of the valley and powdery white flowers

Lilac-floral, refreshing, cyclamen-like. Used in floral notes, such as white flowers, lily of the valley, lily, and lilac. Liral, as an aldehyde, forms Schiff bases in combination with methylanthranilate and indole. It crystallizes at room temperature. Soft and delicate floral notes of lily, cyclamen, and lilac, reminiscent of hydroxycitronellal. Exceptional persistence and diffusion. A powerful mixing agent, it gives fullness to the fragrance throughout all stages of drying. A colorless, viscous liquid, almost non-fluid at room temperature. Practically insoluble in water, soluble in alcohol and oils.

Viscosity further increases with exposure to air, sunlight, and excessive heating, likely leading to polymerization and decomposition. The scent is delicately sweet, light, and floral, with extraordinary persistence and a release that surprises most people who encounter it for the first time. Some claim not to detect the scent of this substance, but upon closer inspection, it generally becomes apparent that this aldehyde possesses strength and volume beneath the delicate surface of the scent.

It has not been found in nature and likely never will be, as its structure and chemical group do not suggest its natural existence. Initially, it was thought that lyral had only fixative properties, such as in high-end perfumes, soaps, and other products. However, it was soon discovered that lyral has a floral fragrance that, when properly "processed" by a perfumer, often surpasses hydroxycitroneallal and any other floral chemical or chemical combination. Its use has thus steadily expanded, from a single lily-of-the-valley flower to a mandatory note in cosmetic perfumes, where persistence and sweetness are required—powdery, lingering finish. It pairs perfectly with common ionones and resinoids (Styrax, Tolu, Peru, etc.) and can both complement and replace hydroxycitroneallal. It is widely recognized that it significantly surpasses hydroxycitroneallal in overall effect and stability. Lyral has a higher boiling point than hydroxycitroneal and is apparently more stable under moderate alkaline conditions. It forms Schiff bases with anthranilates and condensation products with indole, skatole, quinolines, and some other aromatic substances.

The usual concentration for use is from 1 or 2% as a floral modifier or partial fixative up to 6, 8 or 10% in typically floral and persistent perfumes.
