  • Applications

    Fucosterol (CAS 17605-67-3) is used as a plant sterol in cosmetics and personal care formulations for skin conditioning and emulsion stability; it is commonly evaluated as an ingredient in nutraceuticals and functional foods; it can serve as a bio-based additive in polymers and coatings/inks to influence formulation properties and compatibility; in pharmaceutical contexts it may be used as an intermediate or excipient in formulations; its use is formulation- and regulation-dependent across these industries.
