Camellia sinensis Leaf Extract (Decaffeinated)

Decaffeinated Camellia sinensis leaf extract is derived from the young leaves of the green tea plant (Camellia sinensis) through aqueous or hydroalcoholic extraction followed by a decaffeination step, yielding a polyphenol-rich concentrate standardized to ≥50% catechins, predominantly epigallocatechin gallate (EGCG). Formulators select this decaffeinated variant specifically when caffeine is undesirable—such as in products targeting sensitive skin, children's formulations, or where caffeine's vasoconstrictive activity conflicts with the intended skin benefit—while retaining the full antimicrobial and antioxidant potency of the catechin fraction. Its broad-spectrum free radical scavenging, inhibition of lipid peroxidation, and demonstrated antimicrobial activity against gram-positive bacteria make it a valued multifunctional active in natural preservation systems.
