Cinnamic alcohol is a naturally occuring fragrance found in resins and balsams. It is used as a fragrance and flavoring agent for its odor of hyacinth.
Cinnamic alcohol is prepared synthetically by the reduction of cinnamic aldehyde. It is found in the free state or as an ester in cinnamon leaves, hyacinth, essence of daffodil flowers, and various other resins and balsams. The International Fragrance Research Association recommends that it be used in a concentration less than 4% because of its sensitizing ability.
The enzyme alcohol dehydrogenase, present in human skin can convert the cinnamic alcohol to cinnamic aldehyde.
