L-Valine
INCI: VALINE
L-Valine (CAS 72-18-4) is a cosmetic antioxidant functioning as Essential branched-chain amino acid that inhibits lipid peroxidation and. NOAEL 628 mg/kg bw/day (cross-referenced against ToxValDB ECHA IUCLID); EU Regulation 1223/2009 status: permitted. Industrial safety data is also available in the chemical safety database. Same-CAS public records also appear in industrial chemical safety and pharmaceutical data.
Function
Essential branched-chain amino acid that inhibits lipid peroxidation and enhances the accessibility of fat-soluble reactive oxygen species (ROS) for scavenging. The hydrophobic branched-chain side chain of valine partitions into lipid-rich environments (sebum, membrane bilayers), enabling antioxidant protection in the lipid phase of the skin. Component of the free amino acid antioxidant pool.
