Description
Isobutyl methyl tetrahydropyranol features a soft floral scent belonging to the muguet (lily of the valley) family, with additional floral notes reminiscent of rose, cyclamen, lavender and lilac. It is characterized by a versatile aromatic nature, allowing it to be combined with other scents, such as botanicals or citruses, to create complex fragrance compositions. \n\nThis ingredient is synthesized in a laboratory using various methods, including the use of 3-methyl-3-buten-2-ol, a natural substance found in oranges, blackcurrants, grapes and hops. In modern perfumery, there is a growing trend toward using renewable raw materials in its production, contributing to the preservation of the planet's natural resources.
Additional information
