Description and usage notes:

Hercolyn D (as distinct from plain Hercolyn) is a specially deodorised quality of Hercolyn primarily useful as a perfumery solvent rather than an aromatic ingredient, although it does still have some residual odour.  This material is a very high viscosity, sticky, solvent; pourable but thick and straw-to-pale-amber in colour, with good solubility in ethanol. It has extremely helpful fixative effects and is also useful as a general blender. Like BB, DOA and IPM, Hercolyn D is a suitable solvent for candle fragrances. Arctander points out that this is not “a well-defined chemical.  The commercial product under subject name consists of the Methylesters of hydrogenated rosin acids, mainly:
  • A) Tetrahydro methylabietate and
  • B) Dihydro methylabietate.”
It is produced by “By Methyl-esterification of the hydrogenated acids from American Turpentine rosin.”  he also suggests some uses: “Regular Hercolyn has a faint, woody-piney odor of considerable tenacity. Hercolyn D is the most commonly used in perfumery, where the material finds application as a blender-fixative in many types of low-cost fragrance, particularly those designed for household products and for industrial purposes. Ii is particularly suitable for pine odors, but it can be used in modest amounts in most non-floral and a few floral fragrance types.” 
In more recent times Hercolyn has become popular in Oud fragrances and recreations and in the heavier masculine woody-amber types and in leather fragrances, as well as being a useful solvent for non-alcoholic fragrances popular in Arab markets where its high viscosity is an asset.
Arctander goes on to caution that “The excessive use of Hercolyn, e. g. as a diluent, may not alter the odor of a pine fragrance very much, but it may cause some problems in the solubility of the fragrance, or its compatibility with certain cosmetic raw materials in the functional product. And in the more delicate floral fragrances, e. g. the conventional ‘Appleblossom’ type for many household products, there is a distinct limit to the amount of Hercolyn to be used without a perceptible change of the fragrance. The woody-piney notes of Hercolyn are particularly conspicuous in such florals or delicate fragrance types.”  Nevertheless he concludes: “In all, Hercolyn is one of the most useful blenders for low-cost fragrances, and it is, in many cases, a better fixative than Diethylphthalate.” Curiously it is now used in some of the most expensive fine fragrances on the market as well.

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.
