Gum Benzoin / Benzoin
Commonly used in incense-making and perfumery, due to its sweet-vanilla smell and fixative properties (allowing for slower dispersal of essential oils and other mineral fragrances). It can also be used in cosmetics, veterinary medicines, and candles. As a flavourer it is found in alcoholic and non-alcoholic beverages, baked goods, chewing gum, frozen dairy, gelatins, puddings, and soft candies.
There are two types of Benzoin: benzoin Siam (Styrax tonkinensis found in Thailand, Laos, Cambodia, and Vietnam), and benzoin Sumatra (Styrax benzoin, found on the island of Sumatra).
