  • Applications

    Cannabidiol (CBD; CAS 13956-29-1) is used primarily in cosmetics and personal care formulations as an active botanical ingredient in creams, serums, and lip balms; in pharmaceuticals, CBD is used as an active pharmaceutical ingredient in some prescription formulations or is under development for cannabinoid-based therapies; in food processing, CBD extracts are considered a botanical ingredient for dietary supplements, functional foods, or beverage formulations where permitted; in industrial contexts, CBD and hemp-derived extracts are evaluated for use as specialty additives or process ingredients where regulatory frameworks allow.
