Myraldene / Empetal

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.

Descriptions

Each entry contains a short list of scent notes with occasionally other short commentary to assist those who may not have encountered the material previously to decide whether it is of interest: I recommend you make your own assessment of each and every perfumery material you use however.

After pricing, quantity options and other basic details scroll down for narative descriptions: these are intended to assit interested readers as well as potential purchasers to assess the uses and potential of the material in question.

Many of the descriptions contain quotations from the manufacturer of the product and in addition I have quoted fairly extensively from Arctander[1] and from Arcadi Boix Camps[2] – both independent writers and both highly experienced perfumers.

There are also some quotes from Bedoukian[3] where details of the chemistry of a material are significant and from Scent & Chemistry[4] the authors of which have taken an analytical approach to the art of perfumery that is unusual and very useful. Quotations have been included from the extremely useful teaching books by Calkin & Jellinek[5] and Curtis & Williams[6] and Surburg and Panten [7] as well.

Anything not identified as a quotation is my own opinion of the material in question and it’s uses, but I am grateful to many other sources and perfumers as well as the expert authors named here.  Please note that these descriptions are copyright of the author and, other than properly achnowledged fair use quoations as defined in English Law, republication in any form is not permitted.

Spelling

A quick note about spellings: this website is primarily written in British English - it is after all written by an English Perfumer - however most of the authors mentioned here and many of the manufacturers were writing for American audiences and published using American English: where that is the case I have, as far as possible, preserved the spelling used in the source material.  As a result there may be inconsistencies on any given page, but that seemed to me better than arbitrarily changing material in the process of quotation.


Quantity Options

We’ve recently had a change of policy - and bought some new containers - so now all ingredients are sold by weight whether they are solids or liquids.  Only the 10ml and 5ml sizes incorporated in kits, and a few inexpensive materials such as solvents, are still done by volume.  Even the 5ml and 10ml sizes will now be filled to contain 5g or 10g regardless of whether the material is solid or liquid.

Liquids up to 10g in glass bottles (where the fill level may vary as illustrated above), 30g and 50g in HDPE Plastic.

Those materials available in 1Kg are normally supplied in aluminium flasks similar to those used for the 500g size, though we do supply a few materials in HDPE bottles as well.

Finally please note that, with some 500 different materials and so many size options we don’t hold ready-to-sell stocks: when you buy perfumery ingredients we will prepare them to order for you.  This means that large orders can sometimes take a few days to prepare and also that we don’t offer refunds on ingredients, unless of course there is a fault of some kind.
