Please read all information below and general product information before purchase.
Not intended for use in food, vape liquids or other internal use.
Intended to be mixed with other fragrances: on its own, the scent can be dull or even unpleasant.
Do not use undiluted on the skin: it is a raw material, not a finished product.


Helvetolide (Fir) has a soft musky scent, not very animalic, more reminiscent of ambrettolide or orris. The scent is not particularly strong, undiluted use is usual. Typical use is in musk accords, especially in combination with fruit and floral scents. You usually use between 0,1% and 10% of this substance in the fragrance composition. It is quite diffusive and transfers this property to the entire fragrance composition. In perfumes it is mainly a base note, but with a clear radiance to the heart and even to the top of the perfume. It is stable in most products, including soaps and candles.

Keep cool, dry, dark and out of the reach of children.


Helvetolide (Fir) is a colourless to pale yellow liquid at room temperature. The purity is at least 90% (sum of four isomers) and the substance has a fairly long shelf life. Anosmia, the inability to smell (certain) fragrances, is common with musk fragrances: you may temporarily or permanently not smell this substance at all, or barely or distorted. It does not occur in nature, but the synthetic version is used for use as a fragrance. This is partly based on renewable raw materials, partly on fossil fuels. The manufacturer is the Swiss company Firmenich.
