Natural coumarins are most commonly found in tonka beans and cassia essential oils. Vietnam cassia essential oil contains up to 2-5% coumarin. After many years of manufacturing these aroma chemicals, Techvina has always looked for ways to optimize the production method so that the finished product can meet the standards of all customers.
Since the beginning of 2023, Techvina's research and development team has successfully improved production methods. Coumarin has a mild sweet smell and has completely eliminated the smell of cinnamon, pure white color, and long crystalline form. Purity up to 99.9%.
As soon as the finished product from the research room is available, Techvina has sent samples to all customers with needs and good news when most customers approve of the quality.
On average, Techvina can produce 10 tons of natural coumarin per year from Cinnamic Aldehyde and Benzaldehyde production.
