This text has been automatically translated and may contain errors. Aldehyde C12 MNA is a fragrance for use in, for example, perfume or other cosmetics.

Use

Aldehyde C12 MNA has a typical aldehyde smell: greasy, waxy, but also citrus. The smell is strong and can be overpowering. Making a dilution of, for example, 10% can therefore be useful. Typical use is in aldehydic fragrances and for enhancing citrus. You usually use a trace of up to 1% of this substance in the fragrance composition, sometimes a little more. In aldehydic fragrances you use this for the special effect that Chanel No 5 has become famous for. In citrus scents, it returns the natural freshness that the essential oil no longer has. In perfumes it is mainly a top note if you look at the effect, but a base note if you look at the evaporation. It is stable in a surprising number of products, including soap and deodorant. A 10% solution can be made with all common solvents. 96% alcohol is preferred as this promotes the stability of the aldehyde.

Properties

Aldehyde C12 MNA is a colorless to pale yellow liquid at room temperature. The purity is at least 97% when we receive it. The substance is sensitive to oxygen from the air and also spontaneously changes into other substances (trimers). The 97% is therefore quickly less. That does not always matter in this case: the smell becomes less strong, but the other products to be expected are not more allergenic, more irritating or in any other way more dangerous. Also, no disturbing odors or solids are formed. We also recommend stockpiling for no more than 6-12 months and sticking to the expiration date as much as possible. The substance occurs in nature, but the synthetic version is used for use as a fragrance. As a rule we have the product made by the Swiss Firmenich, incidentally we can sell the same molecule from another supplier. This aldehyde is called 2-methylundecanal in common chemistry, but the name Aldehyde C12 MNA is common in perfumery. C12 because it contains 12 C atoms and MNA stands for methyl nonyl acetaldehyde, again an alternative designation for this substance.

Packaging

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 stopper and a white cap.
