GranLux® AOX-G3 ECO is a lignan-rich antioxidant and bacteriostatic extract derived from the knotwood of Norway spruce (Picea abies), dissolved in natural Propanediol. Sourced from uncultivated trees in Northern Scandinavia, this extract is exceptionally rich in polyphenolic lignans. These semi-polar compounds function as potent free radical scavengers across both aqueous and lipid environments, offering a natural, high-performance alternative to synthetic antioxidants.
Key Benefits and Performance
-
Superior Antioxidant Profile: Demonstrates significantly lower IC50 values than BHA and BHT. It provides a superior stoichiometric peroxyl radical scavenging ratio of 1:4 (compared to 1:2 for Trolox®).
-
Broad-Antioxidant Protection: Offers defense against lipid peroxidation, LDL oxidation, superoxide anions, and peroxyl radicals.
-
Bacteriostatic Efficacy: Displays robust antimicrobial activity. CTFA M3 2001 challenge testing shows no microbial growth against Gram-positive (S. aureus), Gram-negative (E. coli, P. aeruginosa), yeasts (C. albicans, M. furfur), and moulds (A. niger).
-
Extreme Stability: Highly resilient to environmental stress; heat stable and exceptionally stable under UV radiation.
-
Non-Phototoxic: UV absorption occurs only in the UVC range, eliminating phototoxicity pathways and supporting the photostability of UV filters in sun care.
