Boronal

Description and usage notes:

An unusual and interesting ingredient with many facets. For this perfumer the immediate first impression is of a sweet-caramel note that doesn’t appear in other odour descriptions (see also Koavone where something similar was detected, though less prominently than here).  The very long drydown odour of this product is very reminiscent of a good grade of natural ambergris, with a slightly powdery quality: this effect lasts for many days on a smelling strip.

An ideal material for linking floral heart and top notes with woodier base notes, also useful to add complexity to violet accords in combination with ionones and methyl ionones. Boronal can feature in ambergris accords and can be used in many other compositions to lend depth and interest.

Symrise describe it as: “Odor: floral, reminiscent of boronia absolute, with violet accents and shades of hay, bran, leather and wood.  Use: Stable in: body lotion (poor), shampoo (good), soap (good), ap roll-on (good), powder (good), cleaner citric (good), cleaner apc (good), bleach (poor).”

Scent & Chemistry point out that boronal is an interim product of the sythesis of beta-ionone into cetalox (the racemic form of ambrofix). They describe boronal as “a floral odorant reminiscent of boronia absolute with sweet violet accents and ambery nuances”

Arcadi Boix Camps, writing in 1999, describes this material as: “a very old product used in one of the bases that formed Alliage.  It is nearly forgotten.  It is strong with important parts of boronia absolute, the jewel of Tasmania, orris and violet. [Boronal] blends well with ambrox, Ambrinol, ambrinoloxide, dihydro-beta-ionone, reseda body, candalum and other sandalwood chemicals, and with sandalwood oil, mate absolute, myroxide, myrrh and resins of orient”
