Properties and stability
Colorless to light yellow liquid. It has the aroma of impatiens but with hints of hyacinth and jasmine.
Storage method
Sealed, store in a cool and dark place.
Synthesis method
Obtained from the direct esterification of cinnamyl alcohol and acetic acid. After the esterification reaction, the finished product is obtained through neutralization, washing, drying and vacuum distillation.
Purpose
Prepare soaps and daily cosmetic fragrances. It is used as a fixative and fragrance ingredient in the preparation of lily of the valley, jasmine and gardenia essences and oriental-flavored perfumes. As edible spices, according to the provisions of Japan’s “Food Additives Official Protocol”, the purity is required to be above 98%, and it must not be used for purposes other than flavoring. Food flavors such as cinnamon, apple, cherry, and pineapple can also be prepared and used in condiments and candies.
