Aldehyde C10

 4,95 incl. VAT  4,09excl. VAT


Aldehyde C10 is an aromachemical for use in, for example, perfume and air fresheners.


Aldehyde C10 has an odour that is difficult to describe. Perfumers simply call it the scent of aldehyde. It is somewhat reminiscent of fat, oil, wax, but it is also often associated with clean and fresh. The scent is very strong, it is almost always used in dilution. A 10% dilution is common, but a 1% dilution may be useful. It is not necessary to dilute yourself: we already sell a 10% dilution of Aldehyde C10 in DPG elsewhere in the webshop.

The substance is used in aldehyde perfumes, a classic group of perfumes of which Chanel n°5 was the first. A usual dose is then up to a maximum of 0,5%. In lower doses, it is used to enhance citrus scents. Citrus scent naturally contains aldehydes like these, but these cannot be trapped in the essential oil, so you have to add them afterwards.

It is mainly a top note in perfumes (although technically a base note!). The substance is not very stable, use with alcohol is recommended because it extends the shelf life.


Aldehyde C10, or decanal, is a colourless to pale yellow liquid at room temperature. The purity after production is at least 97%. The substance does not have a long shelf life, the substance is converted into so-called trimers or decanoic acid. This makes the smell less strong, but it can still be used. The substance occurs in nature, but the synthetic version is used for use as a fragrance. This is usually based on vegetable raw materials.


The 10 and 50 ml packaging is made of brown glass with a black cap. The 250 g package is made of aluminum with a white cap.


Aldehyde C10 is classified as a dangerous substance, with the following characteristics:

H319 - Causes serious eye irritation.
H412 - Harmful to aquatic life with long lasting effects.

An allergic reaction cannot be ruled out, but it is unusual.
