Flavors and fragrances from Kuraray - for the scent of nature

Which fragrance do you prefer: fresh lemon, berry and forest fruits or natural cocoa? Kuraray offers various unique terpenoids that can be used to make synthetic aroma chemicals. Citral, for example, offers a fresh lemon fragrance - and it is also one of the most important raw materials for the production of a wide range of aroma chemicals with the scent of oranges or lilies. In addition to citral, our portfolio includes isoprenol, isovaleraldehyde and prenol. These substances can be converted into a variety of authentically scented flavors - from blueberries and blackberries to coffee, tomatoes, grapes and even white bread.

It is used in many fragrance compositions where a lemon fragrance is required. Citral is also used as the basis for producing other aroma chemicals and vitamin A.

Solvents for household products such as cleaners and air fresheners as well as industrial applications such as coatings and degreasers have to be safe and environmentally compatible. You too can use 3-methoxy-3-methyl-1-butanol (MMB) from Kuraray to make your formulations better and greener.



Solvents play a central role in organic reactions especially when it comes to extracting the organic compound produced. Sometimes the presence of water in the reaction medium can be a real issue as it is the case in Grignard reactions. MTHP from Kuraray is an excellent hydrophobic solvent that can be used to make your organic reactions cleaner, greener and simple
