Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name BETA-SITOSTERYL ACETATE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Beta-Sitosteryl Acetate

Beta-sitosterol 3-O-acetate is a steroid ester obtained by the formal condensation of the hydroxy group of beta-sitosterol with acetic acid. It has been isolated from the mycelia of Cordyceps sinensis. It has a role as a plant metabolite and a fungal metabolite. It is an acetate ester and a steroid ester. It is functionally related to a sitosterol. It derives from a hydride of a stigmastane. — ChEBI
