Common Name(s): Hydrolyzed potato tuber extract,solanum tuberosum hydrolysate,chlorogenic acid antioxidant conditioner
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from chlorogenic acid's catechol radical scavenging, mild brightening from tyrosinase cu2+ chelation, and skin conditioning amino acid humectancy from the hydrolysate fraction.
Why It's Used: Potato hydrolysate provides a cost-effective natural antioxidant with chlorogenic acid content among the highest of any botanical source โ the catechol pharmacophore providing both antioxidant and mild tyrosinase inhibiting brightening activity.
How It Works: Enzymatic hydrolysis (protease + amylase) yields amino acids, oligopeptides, and oligosaccharides from potato protein and starch. chlorogenic acid (5-caffeoylquinic acid, 3-8% dry weight) provides radical scavenging through catechol h-atom donation and mild tyrosinase inhibition via competitive cu2+ chelation (ic50 ~50 um). free amino acids (glutamic, aspartic, lysine) provide sc-compatible humectant conditioning.
