Common Name(s): Platinum thioethylamino hyaluronic acid,platinum thioethylamino hyaluronic acid,platinum-ha conjugate,luxury anti-aging metallic bioconjugate
CAS Number: N/a
DESCRIPTION
What It Does: Provides platinum nanoparticle sod-mimetic antioxidant activity through the platinum surface's ros catalytic dismutation alongside ha's exceptional 1,000ร water retention โ the luxury anti-aging combination of the most antioxidant precious metal and the most potent natural humectant.
Why It's Used: Platinum's sod-mimetic antioxidant activity provides a unique inorganic radical scavenging mechanism โ unlike organic antioxidants that are consumed in the radical reaction, platinum's catalytic surface can scavenge multiple ros without being depleted.
How It Works: Platinum nanoparticles: pt surface provides catalytic oโโขโป โ hโoโ dismutation (sod-mimetic, not consumed); hโoโ โ hโo + ยฝoโ (catalase-mimetic). the thioethylamino linker: s-pt coordination bond tethers pt to ha โ stable conjugate maintaining pt surface catalytic activity. ha backbone: 1,000ร water h-bonding from polyanionic carboxylates.
Typically Found In: Luxury anti-aging,premium humectancy,precious metal cosmetics
