Science
Mechanism of Action
This ingredient operates as an antioxidant by actively inhibiting reactions driven by oxygen, thereby preventing the oxidation and subsequent deterioration of other components within a formula. Beyond its protective role, it acts to condition the skin, and has been identified with properties that may contribute to a bleaching or brightening effect.

Stability
Methoxy PEG-45 Thioctate exhibits dual solubility, being both fat and water soluble. PEG-45, a related component, dissolves extensively in water and various organic solvents. While specific pH stability for this derivative is not documented, some PEG-modified compounds demonstrate pH sensitivity, with stability observed at pH 8.5 but rapid collapse at pH 5.0 in specific cases.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated 'METHOXY PEG-45 THIOCTATE'. However, related PEG ingredients are generally considered safe for cosmetic use. Specifically, PEG-45M is deemed safe in low concentrations, provided rigorous filtration processes eliminate any 1,4-dioxane impurities. The panel has also concluded that alkyl PEG/PPG ethers are safe when formulated to be non-irritating. A general consideration exists regarding anti-PEG antibody formation, which primarily impacts drug delivery systems rather than topical skincare safety. No specific SCCS or FDA status is available for this exact ingredient.
