Isoflavone

Isoflavone (CAS 574-12-9, EC 611-522-9) is a naturally occurring plant polyphenol belonging to the flavonoid family, also referenced under the synonyms 3-Phenylchromone and NSC 135405. It carries no assigned E-code and is classified as a pharmaceutical intermediate with documented activity in personal care, food, and healthcare applications.

In cosmetic formulations, isoflavone functions as an antioxidant by scavenging free radicals and as a skin conditioner by modulating estrogenic receptor pathways at the cellular level, supporting barrier integrity and skin protection. In food and nutraceutical contexts, it serves as a bioactive colorant and stabilising agent, where its chromone backbone contributes to oxidative stability in finished products.

Isoflavone is supplied as a solid in research and commercial grades, compliant with REACH registration requirements applicable to EU-based trade. Procurement teams should confirm purity specifications and batch documentation directly, as grade availability and packaging formats vary by supplier and intended application.
