Genistein is a natural phytoestrogen and isoflavone derived from plants like soy, widely used in cosmetic formulations for its antioxidant, anti-aging, and skin-lightening properties. It helps protect skin cells from oxidative stress, supports collagen production, and is often found in anti-wrinkle creams, serums, and UV-protective products. In the laboratory, genistein also serves as a chemical probe for investigating cell signal transduction pathways, being a known tyrosine kinase inhibitor. This cosmetic-grade Genistein has a CAS number of 446-72-0, molecular formula C15H10O5, and a molecular weight of 270.24. It requires storage at -15 to -20°C, with a signal word of Warning. Molekula supplies Genistein from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
