Benzoin siam, derived from the resin of the Styrax tonkinensis tree found primarily in Thailand, Laos, and Cambodia, is a popular ingredient in perfumery and incense. This resin, once extracted, is often processed into a balsamic material known for its distinctive rich and warm fragrance. The scent profile of benzoin siam is characterized by its sweet, vanilla-like aroma with subtle spicy and almond-like undertones. It exudes creamy, and caramel-like notes, making it deeply soothing and comforting. Benzoin siam not only adds a complex sweetness to fragrances but also acts as a fixative, enhancing the longevity and depth of other notes. Commonly blended with woods, resins, spices, and floral notes, it is favored in oriental and amber scent compositions for its luxurious and inviting scent.
