Artikel Beschreibung
Methoxymethylbutanol (MMB) is a fragrance carrier and solvent designed specifically for use in reed diffuser air fresheners. The product is virtually odourless, with perhaps a faint hint of mint or ether; if it were to have a scent profile, it would be classified as a top note, as the liquid evaporates effectively and steadily. This combination of properties makes it an ideal carrier for fragrance ingredients in reed diffuser fluids and many other types of diffuser liquids. Many fragrance ingredients dissolve readily in it, making it similar to alcohol and DPG in this regard. It is easy to use: simply mix it with the desired fragrance ingredients in the required ratio, and it is ready. A fragrance concentration of 30–50% is common. Methoxymethylbutanol (MMB) has a flash point of 71°C, meaning that a spark is only sufficient to ignite it at temperatures of 71°C or higher. This is a very high temperature, which is why it can be shipped without special restrictions and does not require flammability information on the label. If you wish to reduce its flammability, note that it is miscible with water in any proportion; adding 5–10% water raises the flash point to a level where it is no longer measurable. However, a downside to this is that the solubility of fragrance ingredients decreases. Although the substance is permitted for use in cosmetics, such use is uncommon, and there is limited experience with it; therefore, we do not recommend using it in this way. At room temperature, Methoxymethylbutanol (MMB) is a colourless to pale yellow liquid. It has a minimum purity of 99% and a long shelf life. It is a synthetic substance derived from fossil-based raw materials and is manufactured by the Japanese company Kuraray. Like many fragrance ingredients, this substance is quite volatile; be sure to keep it in a tightly sealed container until use, otherwise the bottle could gradually empty without you noticing. This substance is made from isoprene, derived from petrochemical sources such as crude oil. Its biodegradability in the environment is moderate.
