  • Applications

    Costic acid is a natural product component associated with Costus species and is commonly evaluated for use in perfumery as a fragrance ingredient and potential fixative. In cosmetics and personal care, it may be incorporated as a botanical extract constituent or intermediate in formulations. It can serve as an intermediate in organic synthesis for industrial manufacturing, and may have applications in polymers and plastics as a specialty additive or precursor. In coatings and inks, it may be used as an additive or intermediate depending on the formulation, while other uses are typically subject to local regulations and formulation limits.
