Description and usage notes:

Typically powerful aldehyde impact, here with a distinctive fruity-orange character, with an exceptionally good ‘fresh-air’ quality.  It is longer lasting than most too and can contribute to many types of fragrance particularly citrus, muguet and other floral types.  Interestingly this material has been on the market for a very long time, having originally been developed from research into insect repellents, but has only relatively recently become popular in fine fragrances.

The same aldehyde is produced by Givaudan (Empetal and Myraldene) and is also offered by many other manufacturers to various purity levels and mixtures of isomers but the material offered here is manufactured by IFF who give a typically short and simple description: “An aldehydic with orange, ozonic and fruity characteristics. Strong and persistent. Clean outdoors effect” 

Arcadi Boix Camps, writing in 1978, mentions this material in the context of Aldehydes in general, saying that “…products like the so-called myrac aldehyde, with its greasy, citric, flowery scent, something like lauric aldehyde or the citronellal and geranyl oxyacetaldehydes, have interesting metallic flowery notes”.

Arctander describes the odour as: “Powerful and penetrating, waxy-citrusy, in dilution fresh-floral, clean and light odor with some resemblance to Dodecanal, Cyclamal and Myristic aldehyde.”

He goes on to say that: “This aldehyde, marketed several decades ago, has taken a long time to become popular, and it is questionable if one can make that statement even today. It is beyond doubt, that the aldehyde has an excellent influence upon Bergamot and other citrusy odors, and that its effect includes the “aldehydic” top- note effect to a certain degree. It performs well in soap and adds freshness to a wide range of odor types from Pine needle to Muguet, from Violet to Lilac, etc. Its very low cost makes it a candidate for industrial masking, detergent fragrances and many other large-volume products. It blends well with Ionones and the CedarWood-like Cyclohexane derivatives in modern soap odors.” 

Finally he mentions that “The hydroxylated aldehyde, known under the name ‘Lyral’, is listed in this work as Hydroxymethyl-penty l-cyclohexene-carbox-aldehyde. It is far more successful than the title aldehyde, but it is in no way olfactorily related to it.”

It is produced to a minimum 96% purity (the current batch is over 99%), lasts about two days on a smelling strip and typical use levels range from tiny traces up to about 10% of the fragrance concentrate.

As this is such a powerful material and so easy to overdose we also offer it at 10% in IPM.
